Description

Polymeric synthetic resin composite waterproof sheet, manufacturing method and construction method using same {COMPLEX WATERPROOF SHEET OF MACROMOLECULE SYNTHETIC RESIN

The present invention relates to a polymer synthetic resin composite waterproof sheet, a method for manufacturing the same, and a construction method using the composite waterproof sheet manufactured by the same method.

In particular, the present invention is the upper layer of the polymer synthetic resin sheet and the polymer to give flexibility and adhesion by mixing rubber and tackifier in polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC) which is a waste of the polymer synthetic resin Provided is a composite waterproof sheet composed of a rubberized asphalt sheet or a lower layer of a sticky unvulcanized rubber sheet bonded to an upper layer of a synthetic resin, and a method of manufacturing the same. In addition, the present invention provides a construction method using such a composite waterproof sheet.

In more detail, the present invention is a composite waterproof sheet of which the upper layer is composed of polymer synthetic resin sheet and the lower layer is composed of rubberized asphalt sheet or tacky unvulcanized rubber sheet. This is a waterproof sheet used for reinforced concrete structures such as rooftop waterproofing, parking lot, ammunition, hangar, etc .. The upper layer and the lower layer are made of waterproof materials with different materials and properties, but the materials are integrated into a composite waterproof sheet. In order to complement each disadvantage and to maximize the advantages, integrally connect and joint between the rubberized asphalt sheet of the lower layer and the adjacent rubberized asphalt sheet, or between the adhesive unvulcanized rubber sheet and the adjacent adhesive unvulcanized rubber sheet. First room The method of manufacturing a composite waterproof sheet which achieves the effect of construction, and then obtains a perfect waterproof construction effect in a double by connecting the polymer composite sheet of the upper layer and the adjacent polymer synthetic sheet in one piece to obtain a waterproof construction effect. And a construction method using the same.

Rainwater or groundwater inundation and penetration into the cracks caused by shrinkage and relaxation of the reinforced concrete structures of the finished construction and civil engineering, or the cracks caused by floating settlements, will lead to a decrease in the life of the finished construction and civil engineering structures. It is a very important factor for.

As a conventional waterproof technique for this, the sheet waterproofing material has been used as the most popular waterproof sheet of the rubberized asphalt sheet.

As a conventional rubberized asphalt sheet, asphalt is the main material. Asphalt property itself has waterproofness and low price, so it has been commonly used. However, asphalt sheet has poor adhesion with the base concrete to be waterproofed, and when water penetrates, there is a closed end where water moves under the waterproof layer. Since the connection bonding between the asphalt sheets is made by thermal fusion, there is a possibility that defects are generated due to the lack of complete bonding at the connection part or the end part, and rubberization is caused by aggregate or reinforcing bars before and after waterproofing the asphalt sheet. As a result, the asphalt sheet was damaged, which caused a lot of defects.

In addition, conventional coating film waterproofing materials include asphalt-based coating film waterproofing materials or rubber-based coating film waterproofing materials such as CR rubber. The conventional coating film waterproofing material has advantages and disadvantages according to the material, but the coating film waterproofing material is difficult to form a uniform and uniform thickness even if the coating is repeatedly applied over several times to form a stable thickness while performing a waterproofing coating regardless of the material, Not only there are limitations in construction such as delayed post-operation due to long curing time after construction due to large amount of pinholes and air bags (air bags) caused by bubbles on the coated surface. In addition, after construction, the waterproofing layer may be damaged by aggregates or reinforcing bars, which may provide a resource provider.

In general, the conventional waterproofing materials are installed by attaching a waterproofing layer protective material such as ethylene vinyl acetate (EVA) foam sheet or PE foam fibrous plate on the outer surface (surface) of the waterproof layer so as not to damage the waterproof layer when backfilling. However, the waterproofing layer and the protective material are not completely adhered, so that the protective material attached during the backfilling process after the waterproofing layer is pushed away or damaged and the waterproofing layer is also damaged to obtain a waterproofing effect. This is a contradiction of the dysfunction in which the protective material to protect the waterproof layer provides the cause of the important defect. On the other hand, in order to protect the waterproof layer, there is a method of stacking bricks on the surface of the waterproof layer to form a wall, and then backfilling, but there is a problem that the construction air is delayed and the construction cost is excessive.

In addition, sheets made of high-molecular synthetic resins such as EVA and HDPE combine very strong tensile and tear strength with high elongation, excellent chemical resistance and durability, but are excellent as waterproofing materials, but they are extremely poor in adhesion and cannot be bonded to the ground concrete. It is not possible to use it as a waterproofing material because it has no exponential effect due to the failure of the connection part because it is impossible to bond the sheet and sheet, but it is applied to the waterproofing material of the induction method such as turn-nel, but it cannot be attached to the base concrete. Since the connection between the sheet and the sheet must be melted and joined with the high temperature hot air of 300 ℃ ~ 500 ℃, the joining work is cumbersome and the effect is incomplete, so it is inevitable to leak or Induce water leaking or flooding after immersion and waterproof construction It was applied only to the waterproofing method of water treatment, and it was not used as a waterproofing material for general civil engineering and construction structures and could not be used.

As described above, the conventional waterproof material, regardless of the type, and the homogeneous waterproof material consisting of a single main material is the main dominant, the inventors are formed by integrating different materials excellent in each of the physical properties and waterproof properties, although the material is very different. If you manufacture a composite waterproofing material, it will be the best and groundbreaking composite waterproofing material by supplementing each disadvantage and maximizing its advantages, and the construction effect is obtained by double-waterproofing effect with waterproof material of different materials and materials. It was conceived that it would be waterproof construction without any defects, and high-molecular wastes such as PP, PE, PS, ABS, PVC, which are general-purpose resins, which are used for various industrial wastes such as industrial or agricultural use and discarded. Recycling synthetic resins has helped to remove environmental pollution.

In order to satisfy the above conditions, if the upper layer is made of polymer synthetic resin and the lower layer is made of rubberized asphalt or sticky unvulcanized rubber, the lower layer of rubberized asphalt or unvulcanized sticky rubber exhibits perfect waterproofing. In addition, the polymer resin of the upper layer is the perfect waterproofing material as the second perfect waterproof function, and the upper layer of the polymer synthetic resin protects the rubberized asphalt or adhesive unvulcanized rubber of the lower layer from aggregate or reinforcing bars during construction. It was conceived that it is the most ideal waterproofing material which is different from the conventional waterproofing material in terms of waterproofing construction by fundamentally blocking the defects in construction.

However, in the composite waterproof sheet of the polymer synthetic resin, the upper polymer synthetic resin layer has advantages of strong tensile strength, chemical resistance and durability, but lacks flexibility and hardens in winter, so it is impossible to precisely construct corners. In particular, the physical properties of the polymer synthetic resin sheet is extremely poor adhesiveness and there are many problems in the connection bonding between the polymer synthetic resin sheet, and also the bonding of the polymer synthetic resin of the upper layer and the rubberized asphalt or adhesive unvulcanized rubber of the lower layer is poor. Since the upper layer and the lower layer are not integrally attached and there is a problem that these layers are separated, the composite sheet having the polymer synthetic resin as the upper layer has many problems in practical use.

The inventors added rubber to the polymer synthetic resin and added plasticizer oil and tackifier to add flexibility and tackiness to the polymer synthetic resin, enabling precise construction of corners and maintaining continuous flexibility even in homogeneous groups. By providing self-adhesiveness and adhesiveness, the bonding between the polymer synthetic resin sheet is simple and integral, but the effect is perfect.The polymer synthetic resin sheet on the top and the rubberized asphalt sheet or adhesive on the bottom It is firmly attached to the unvulcanized rubber sheet so that there is no layer separation, thereby providing a perfect composite sheet.

In particular, the above-mentioned polymer synthetic resin is used for recycling industrial waste by using polymer synthetic resins such as PP, PE, PS, ABS, and PVC, which are general-purpose resins that are used for industrial or agricultural purposes, and are disposed of for various industrial wastes. While contributing to the elimination of environmental pollution, it is cost-effective and provides a good quality waterproofing material at an affordable price.

Hereinafter, the present invention will be described in detail with reference to Examples.

Example 1

Preparation of Upper Layer 10-Polymer Synthetic Resin Sheet

1. The composition of the polymer synthetic resin sheet is as follows.

Polymer resin: ethylene vinyl acetate EVA copolymer ------------------- 10%

Polypropylene PP --------------------------------------- 10%

Polyvinyl Chloride PVC -------------------------------------- 20%

Polystyrene PS ----------------------------------------- 30%

Rubber: Natural rubber or Synthetic rubber (SBR rubber, BR rubber, IR rubber, ⅡR rubber

EPT rubber, NBR rubber, SBS rubber, SIS rubber) ---------- 30%

Plasticizer: DOP (dioctyl phthalate) --------------------------------- 5%

Soya bean oil -------------------------------- 0.5%

Tackifier: Petroleum resin ------------------------------ 5%

Kumarone resin ---------------------------- 5%

Polybutene ---------------------------------- 15%

Filler: calcium carbonate ---------------------------- 7%

White carbon ----------------------------------- 10%

In the above composition, the content of the polymer synthetic resin and the rubber corresponds to the raw material as the main component, and the addition ratio of the plasticizer, the tackifier and the filler is determined based on 100% of the total weight of the resin and the rubber as the raw material. Addition amount of the imparting agent and filler indicates the relative addition percentage (%) with respect to 100% of the total amount of synthetic resin and rubber as raw materials.

The polymer synthetic resin is a thermoplastic resin, and recycled industrial wastes of PE, PP, PS, ABS, and PVC, which are general-purpose resins, and EVA uses raw materials. In the above blending ratio, recycled ABS resin as industrial waste may be added in place of EVA (10%) as a raw material, and recycled PE (10%) in place of recycled PP (10%). It is necessary to replace and add one and stir, and PVC is added by regenerating soft PVC. When using other types of recycled resins other than the above-mentioned polymer synthetic resin, which is a general-purpose resin, tackifiers and plasticizers are added with appropriate variation. Can be used.

When the petroleum resin and the tackifier are added at least 10%, respectively, the resin elasticity and the impact resistance are inferior and the tensile strength tends to be lowered. The polybutene also functions as a tackifier and a plasticizer.

The polymer synthetic resin sheet constituting the upper layer of the polymer synthetic resin composite waterproof sheet of the present invention is a general-purpose resin PP, PE, PS, ABS, PVC, EVA. Kneader mixer or Banburyy mixer which is a closed pressurized mixing machine by adding plasticizer, tackifier, and filler to at least one rubber base of natural rubber or synthetic rubber to polymer synthetic resin such as ABS After mixing and stirring evenly in the machine, the extruder or calender is extruded or rolled to a thickness and a constant width of 0.5 mm to 2 mm, and withdrawn to a sheet while attaching the release paper 20 to one side and cutting it to a certain length and rolling it roundly. The sheet is produced only by the polymer synthetic resin itself.

The polymer synthetic resin sheet is prepared by injecting a polymer extruder and an additive as raw materials into a hopper of a mixer (mixtruder), and mixing, stirring, and extruding in a screw inside the extruder. Insufficient agitation, causing the polymer synthetic resin sheet to separate or form a layer, which may cause defects. It is a closed mixing machine in a mixer or short-barrier mixer at a temperature of 140 ° C. to 170 ° C. corresponding to the heat deformation temperature of the polymer synthetic resin. Mixing and stirring in a compulsory manner while pressurizing at a pressure of 7 kg / cm 2 was uniformly mixed with the rubber and resin to be mixed, evenly dispersed without layer separation or evenly mixed.

The inventors selected PP, PE, PVC, ABS, and PC, which are polymer synthetic resins, respectively, and rolled the mixture by stirring at 140 ° C to 170 ° C while adding rubber, plasticizer, tackifier and filler in a mixer. As a result, the resin's inherent physical properties such as resin elasticity and impact resistance are inferior, and the flexibility is very high. The surface hardness reaches 30 degrees, and a primer is applied and bonded for adhesion between the resin and the resin. When peeled off, the adhesion was weak and incomplete bonding. As a result, the adhesion is partially achieved by rubber and tackifier added to PP, PE, ABS, EVA, and PVC (the stirring of PVC alone is stirred at 110 ° C). Many polymer synthetic resins, PP, PE, PVC, EVA and ABS, were found to be incompletely bonded due to their lack of wetness and adhesion.

The present inventors noted that polystyrene resin PS has a very poor elongation rate, and is hard to break and breaks when impacted. However, the PS resin is added to the above-described PP, PE, or PVC resin. The sheet was prepared by mixing rubber and plasticizer, tackifier and filler, and evenly mixing the mixture to prepare the sheet. In other words, the sheet had excellent flexibility, good tensile strength and elongation, and excellent resin elasticity, impact resistance and adhesion.

Polymer synthetic resin sheets such as PP, PE, and PVC are dried on the surface, and mixed with a small amount of semi-dry soybean oil 0.5% and PS resin, and stirred. When the surface of the film is wet, it exhibits a synergistic effect with the added tackifier. The bond between the sheet and the polymer, which is a polymer synthetic resin, was further improved (however, when 1% or more of soybean oil was added, it was not good to add more than 1% because soybean oil was excessively extracted and the adhesion was lowered.

While mixing the polymer synthetic resin and rubber, the temperature of the roller (open roller), which is a rubber mixing machine, is first increased to 70 ° C. to 80 ° C., rather than adding the rubber directly to the polymer synthetic resin in a mixing machine or a short-bar mixer. Addition of rubber while stirring EVA to stir evenly to disperse the EVA and rubber. Put into the mixer or half-barrier mixer and stir by adding polymer synthetic resin such as PS, PE, PP, PVC It was good to stir well while dispersing evenly, or to stir well by adding rubber while stirring the PS resin in the mixer of 140-170 ℃ and then adding and stirring thermoplastic resin such as PP, PE, PVC, ABS, etc. Rather than mixing and stirring the synthetic polymer synthetic resin alone, the synthetic polymer resin of various varieties This property is for stirring a mixture was further improved.

Example 2

The inventors of the present invention is a polymer synthetic resin by adding a natural rubber or synthetic rubber and a tackifier and a plasticizer, filler to the polymer synthetic resin is very poor adhesion between the polymer synthetic resin sheet formed of a polymer synthetic resin such as PP, PE, EVA, etc. Although the adhesiveness of the sheet was improved well and the bonding of the rubberized asphalt sheet or the adhesive unvulcanized rubber sheet on the opposite side of the polymer synthetic resin sheet was improved, the polymer synthetic resin sheet and the rubberized asphalt sheet or the adhesive unvulcanized rubber were improved. In order to further improve the bonding of the sheet, the adhesive reinforcing sheet 24 obtained by depositing and drying natural rubber or synthetic rubber latex on a sheet punched like a fiber or a mesh made of fiberglass or PE or the miga of the present invention Dilute 200 weight of sulfur rubber dough to 1000 weight of toluene Adhesion reinforcement sheet 24 obtained by immersing the dissolved thin rubber primer in a dry state is superimposed on the upper portion of the polymer synthetic resin sheet, and the rubberized asphalt sheet or the adhesive unvulcanized rubber sheet is disposed on a certain thickness ( 1 mm to 2 mm), the upper polymer synthetic resin sheet layer and the lower part are formed by the adhesive reinforcing sheet 24 in which the hole is punched like a mesh or The rubberized asphalt sheet layer or the sticky unvulcanized rubber sheet layer is more firmly attached to obtain a perfect composite sheet, and the layers of the polymer synthetic resin sheet of the upper layer and the rubberized asphalt sheet or unvulcanized rubber sheet of the lower layer are completely separated and not completely separated. Can be bonded.

In general, the waterproof construction of underground structures is waterproofed on the outer wall of the concrete structure, and the EVA foam sheet or PE foam fiber board is attached or racked to the outside (surface) of the completed waterproof layer, and then the backfill is made to protect the waterproof layer. To complete the construction. However, EVA foam sheet or PE foam fiber board is not completely bonded with the waterproofing material. Therefore, during the backfilling process, the waterproofing material of the waterproofing layer is pushed away or damaged due to the loss of the waterproofing layer. There is a fatal disadvantage of dysfunction that provides the cause of defects (waterproof failure), and the protection of the waterproof layer by stacking bricks is expensive and burdensome and delayed air.

On the other hand, the composite waterproof sheet of the present invention excludes EVA foam sheet and PE foam fiber board or racking to protect the waterproof layer while improving the defects caused in the backfilling process, and attaches wet cement mortar kneaded with water to the waterproof layer. Use as waterproofing layer protection material.

When waterproofing is performed by the method of the present invention, a composite waterproof sheet is used as an intermediate medium, and the inside (inside) and the outside (outside) are sealed with cement concrete, thereby allowing perfect plywood construction.

Manufacturing Process of Polymer Composite Waterproof Sheet

Looking at the manufacturing process of the composite waterproof sheet according to the present invention according to the components and component ratios as described above, first, while stirring the natural rubber or synthetic rubber (30%) to the roller by adding EVA (10%) and evenly mixed stirring The mixture is mixed in a sealed mixer, a mixer or short-barrier mixer, mixed with PS (30%) and evenly mixed with PP (10%), PVC (20%) and plasticizer DOP (5%) and soybean oil (0.5). %) And stir to evenly mix, add tackifier petroleum resin (5%), guarone resin (5%) and polybutene (10%) and stir, add filler calcium carbonate (14%) Finally, the mixture is stirred to evenly mix to obtain a polymer synthetic resin composition.

Then, polybutene (10%), modified phenolic resin (10%), petroleum resin (20%) and vinyl acetate resin (5%), which are tackifiers, were added to the mixture and stirred and mixed to disperse evenly. Calcium carbonate (30%), white carbon (10%) and clay (10%) were added and stirred and mixed. Finally, DM (2%), D (0.8%), T / T (1%), After addition of NA-22 (1%), the mixture was stirred well to prepare an unvulcanized rubberized asphalt dough.

Alternatively, natural rubber or synthetic rubber (SBR rubber, IR rubber, EPT rubber, IIR rubber, CR rubber, NBR rubber, Urethan rubber, CPE rubber, SBS rubber, SIS rubber) and at least one rubber main body (100%) is added and stirred. With respect to the rubber base material, polybutene (10%), petroleum tackifier, which was mixed and stirred with magnesium oxide (5%), stearic acid (2%), zinc oxide (5%), and sulfur (2%) as vulcanizing aids. Resin (5%), Kumaron resin (7%) and rosin (5%) were added to the mixture and stirred.Then, calcium carbonate (20%) and cray (20%) were added and mixed. While adding carbon (8%) and black carbon (6%), process oil (5%) and DOA (10%), which are softeners, are added and stirred to evenly mix. After cooling the unvulcanized sticky rubber dough prepared in this step, the rubber roller was stirred again while vulcanizing the rubber dough, DM (2%), M (1%), and T / T (1%). ), TRA (2%) is added and stirred to prepare a sticky unvulcanized rubber dough which is converted to vulcanized rubber at room temperature.

After the above process, the unvulcanized sticky rubber dough and the unvulcanized rubber dough or the rubberized asphalt dough are manufactured, and then the first calender machine is used to make a constant width and thickness of 0.5 mm to 2 mm. Rolling out the polymer synthetic resin sheet of the sheet, inserting a mesh sheet made of glass fiber as a reinforcing material, or inserting the sheet punched like a mesh on top, the glass fiber mesh on one side of the rolled and drawn polymer synthetic resin sheet Rolling out the second calender machine in the first calender machine and attaching the rubberized asphalt sheet or the adhesive unvulcanized rubber sheet to one side with the adhesive reinforcing sheet attached to one side while being attached. Attached to be applied with a thickness, withdrawal paper is attached to the outer surface, withdrawal, rolled up and cut to a certain length The.

Accordingly, a polymer synthetic resin sheet is formed on one side of the adhesive reinforcing sheet, and the composite waterproof sheet of the present invention coated with rubberized asphalt sheet or adhesive rubber sheet on the opposite side of the adhesive reinforcing sheet is obtained. While attaching a release paper manufactured separately to the outer surface of the composite waterproof sheet, cut it to a certain length and wrap it roundly.

If there is only one calender machine, first, the polymer synthetic resin is rolled out and drawn out, and then the glass fiber mesh, which is an adhesive reinforcing sheet, is attached to the upper part and drawn out, and then it is repeated in the same machine and the rubberized asphalt sheet or the adhesive unvulcanized rubber sheet is repeated. At the same time as the rolled out, and the adhesive reinforcing sheet prepared first is applied to the polymer synthetic resin sheet is inserted in a certain width and thickness, while attaching a release paper to the outer surface cut and rolled round packaging.

In addition, when the adhesive reinforcing sheet is not inserted in the middle, the synthetic resin sheet may be rolled out and rolled out while directly applying the rubberized asphalt sheet or the adhesive unvulcanized rubber sheet. However, in the case of manufacturing by an extruder, it is different from just extracting from the extruder, and the rest of the processes are prepared in the same manner.

Construction method using composite waterproof sheet

The construction process using the composite waterproof sheet of the present invention as described above will be described.

On the upper surface of the basement structure or the basement concrete on the roof, a plurality of composite waterproof sheets are bonded to each other in a state where they are attached to each other.

As described above, when constructing the composite waterproof sheet according to the present invention, the unvulcanized adhesive rubber sheet or rubberized asphalt sheet attached to one side of the composite waterproof sheet is brought into close contact with the upper surface of the base concrete, and the polymer synthetic resin sheet is upwards. In the facing state, each waterproof sheet is constructed so as to overlap a predetermined width (10 cm) with a neighboring waterproof sheet. In this state, when the pressure is applied from the upper side, the adhesive unvulcanized rubber sheet or rubberized asphalt sheet is firmly adhered to the upper surface of the cement concrete, and because of the strong adhesiveness of the adhesive unvulcanized rubber sheet or rubberized asphalt sheet, The overlapping parts of the connecting parts of the waterproof sheet are bonded to each other as one body to be integrated into one component, and the upper polymer synthetic resins are also bonded to integrate the overlapping parts together. Construction can be done.

In addition, the polymeric synthetic resin sheet or adhesive unvulcanized rubber sheet or rubberized asphalt sheet is drawn out by rolling to a thickness of 0.5 mm to 1 mm, and the sheet is cut into 5 cm to 8 cm widths, cut into tapes, and rolled up to produce a sheet. An adhesive tape for one connection connection part is attached to the upper part of the connection part constructed by overlapping the above-mentioned composite waterproof sheet and the upper part of the end part of the composite waterproof sheet where the composite waterproof sheet is attached to the ground concrete. As a result, it is possible to obtain a perfect construction effect.

Therefore, even if the construction area is wide, two kinds of different waterproofing materials are used to achieve the effect of waterproofing the entire area in one piece without any gaps, and then the upper part of the connection part between the sheet and the sheet and the end portion of the sheet attached to the base concrete. Attaching a tape formed of polymer synthetic resin or adhesive unvulcanized rubber or rubberized asphalt, which is the material of the waterproofing material, has a characteristic of exhibiting a perfect waterproofing effect by obtaining a triple waterproofing effect.

After completing the construction by attaching the composite waterproof sheet of the present invention to the ground concrete, attaching the wet cement mortar kneaded with water on the surface of the waterproof layer to a thickness of 1.5cm ~ 2cm, the mortar is cured and cured while the polymer of the present invention It is strongly bonded to the surface of synthetic resin to protect the waterproof layer safely during backfill construction.

The composite waterproof sheet manufactured by the present invention is self-adhesive, so that in summer, the pressing portion of the sheet and the sheet are connected by pressing, and the adhesive is integrally formed. However, the surface of the ground concrete in winter or due to site conditions in winter When contaminated with the cement powder and dust, a rubber primer prepared by dissolving 40 weights of the above mixed viscous unvulcanized rubber or rubberized asphalt dough in 150 weights of toluene is prepared and coated on the sheet-to-sheet connection part. After applying the spray or brush to the bottom of the sheet to be attached, the construction as described above is more integrally combined and completely attached to complete the construction.

After completion of construction, the adhesive unvulcanized rubber or rubberized asphalt layer bonded with the ground concrete is gradually activated and cured (vulcanized), which not only strengthens the adhesion with the ground concrete, but also exhibits strong tensile strength and tear strength and high elongation. Done.

In the case of waterproof construction using the composite waterproof sheet according to the present invention, the first sticky unvulcanized rubber layer or rubberized asphalt layer is firmly and strongly adhered to the ground concrete, and exhibits perfect waterproof function first. Not only did the polymer resin layer of the upper layer exhibit perfect waterproof function in the second time, but also by attaching the above-described waterproofing tape to the upper part of the sheet and the end portion of the sheet, and then completely sealing it. In order to achieve the most perfect and breakthrough waterproofing effect by showing the effect of waterproofing during construction, during the construction, the upper polymer synthetic resin layer prevents damage of the waterproofing layer from aggregate or rebar during construction, and after the construction is completed Dough wet cement mallet-attach to refill This prevents damage to the waterproof layer of the stand.

In addition, the polymer synthetic resin contributes to the recycling of industrial wastes by using polymer synthetic resins such as PP, PE, PS, PVC, and ABS, which are general-purpose resins, which are used for various purposes, such as industrial and agricultural, and disposed of.
