Photocatalyst is under the irradiation of light, can produce similar photosynthetic light-catalyzed reaction, produce oxidability extremely strong free hydroxy and active oxygen, there is very strong photoredox function, the various organic compounds of oxidable decomposition and part inorganic matter, can destroy the cell membrane of bacterium and solidify viral protein, can kill bacteria and decomposing organic pollutant, organic pollution is resolved into free of contamination water (H2O) and carbon dioxide (CO2), thereby there is extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, air purification function.The characteristic of photocatalyst is to utilize airborne oxygen molecule and hydrone that contacted organic matter is converted to carbon dioxide with water, and self does not change, and but can promote the material of chemical reaction, and the term of validity is very permanent in theory, and maintenance cost is low.Meanwhile, titanium dioxide itself is nontoxic.The action principle of photocatalyst is mainly reflected in following two aspects: one, the organic pollution decomposition principle of photocatalyst: nano level TiO2, under the irradiation of ultraviolet light, produces electron hole pair owing to having absorbed luminous energy.These holes can migrate to rapidly surface to (photocarrier), and activate the H2O of its surface attachment and O2 and produce hydroxy (OH) and active oxygen (O).And the extremely strong material of these two kinds of oxidisability is understood rapidly and the hydrocarbon reaction of bacterium, virus and the macromolecule of catalyst surface attachment, generate harmless CO2 and water.This action principle is now just being widely applied in air cleaning and water sterilization field.Photocatalyst net is combined with ultraviolet lamp, can be applicable to the purification of fresh wind or air-conditioning system, sewage disposal flow process etc.There is energy-conservation, long-acting, non-secondary pollution.Two, the clean principle of the hydrophilic self-cleaning of photocatalyst: photocatalyst can effectively decompose the pollutant being attached under the effect of ultraviolet light, and produces a clean surface.The hydroxy (OH) simultaneously generating can be combined with airborne H2O and be made catalyst surface produce hydrophily.And adopted the building wall of this technology, owing to having hydrophily, under the flushing of rainwater, its surperficial solid-state attachment such as dust can be very easy to be cleaned, and has kept the clean of skin face, has saved a large amount of artificial cleaning cost.The photocatalyst material that this class is attached to building wall can utilize the ultraviolet composition in sunlight to carry out work.But uv energy required when it is excited is first higher, therefore must before producing, with high-intensity quartz burner, excite.As can be seen here, as ultraviolet light generation source---quartz burner is vital to the application of photocatalyst technology.
Owing to using nano material to make electrode, thereby electrode activity is high, and water molecule reaction is accelerated, and electrolytic cleaning effect significantly improves.
Cleaning sink material is owing to adopting nano plastic, has that intensity is high, the feature of environmental protection.PET polymerization intercalation complex technique for PET nano plastic, together joins organic montmorillonite and PET monomer in polymeric kettle and is prepared from.
ABS resin is one of five large synthetic resin, its impact resistance, heat resistance, lower temperature resistance, chemical proofing and excellent electrical properties, also there is the features such as easy processing, product size is stable, lustrous surface is good, easily application, painted, can also carry out surperficial metalling, plating, welding, hot pressing and the secondary operations such as bonding, being widely used in the industrial circles such as machinery, automobile, electronic apparatus, instrument and meter, weaving and building, is the thermoplastic engineering plastic that a kind of purposes is extremely wide.General performance: ABS outward appearance is the opaque ivory white pellet that is, and its goods are managed to make do into colourful, and have high gloss.ABS relative density is 1.05 left and right, and water absorption rate is low.ABS is good with the associativity of other materials, is easy to surface printing, coating and coating and processes.The oxygen index (OI) of ABS is 18～20, belongs to combustible polymers, and it is yellow that flame is, and has black smoke, and send special stink.Mechanical property: ABS has good mechanical property, and its impact strength is fabulous, can at extremely low temperature, use; The high abrasion resistance of ABS, good stability of the dimension, has again oil resistivity, can be used for the bearing under medium load and rotating speed.The creep resistant of ABS is larger than PSF and PC, but less than PA and POM.It is poor in plastics that the bending strength of ABS and compressive strength belong to.The mechanical property of ABS is subject to the impact of temperature larger.The heat distortion temperature of thermal property: ABS is 93～118 ℃, and goods also can improve 10 ℃ of left and right after annealing in process.ABS still can show certain toughness in the time of-40 ℃, can in the temperature range of-40～100 ℃, use.The electrical insulating property of electric property: ABS is better, and is subject to hardly the impact of temperature, humidity and frequency, can under most of environment, use.Environmental performance: ABS is not subject to the impact of water, inorganic salts, alkali and multiple acid, but dissolves in ketone, aldehydes and chlorohydrocarbon, is subject to glacial acetic acid, the erosion of plant wet goods can produce stress cracking.The weatherability of ABS is poor, easily produces degraded under the effect of ultraviolet light; After outdoor half a year, impact strength decreased half.The processing characteristics of ABS plastic: ABS is equally the thermoplastic that a kind of processing characteristics is good with PS, available general processing method processing.The fluidity of molten of ABS goes with PC than PVC, but poorer than PE, PA and PS, similar with POM and HIPS; The flow behavior of ABS belongs to non-newtonian fluid; Its melt viscosity and processing temperature and shear rate have relation, but more responsive to shear rate.The Heat stability is good of ABS, is not prone to signs of degradation.The water absorption rate of ABS is higher, before processing, should be dried processing.The drying condition of general goods is 80～85 ℃ of temperature, time 2～4h; Drying condition to the goods of specific (special) requirements (as electroplated) is 70～80 ℃ of temperature, time 18～18h.ABS goods work in-process easily produces internal stress, and the large I of internal stress is checked by immersing in glacial acetic acid; As too large in stress and goods counter stress cracking absolute prohibition, should carry out annealing in process, and actual conditions is to be put in the interior 2～4h of hot air circulation drying oven of 70～80 ℃, then is cooled to room temperature.ABS production method is divided into blending method and Graft Method.The main manufacturer in the world adopts the first grafting method of blending more mostly now, and this method is divided into again emulsion graft polymerization-suspension SAN blending method, emulsion graft polymerization-suspension SAN blending method, emulsion graft polymerization-body SAN blending method.
PLC is that programmable logic controller (PLC) essence is a kind of computer that is exclusively used in Industry Control, its hardware configuration of programmable logic controller (PLC) is substantially identical with microcomputer, and basic comprising is: one, power supply: the power supply of programmable logic controller (PLC) plays a very important role in whole system.If neither one good, reliably power-supply system cannot work, therefore, the manufacturer of programmable logic controller (PLC) also attaches great importance to the Design and manufacture of power supply.General alternating voltage fluctuation, in+10% (+15%) scope, can not taked other measure and PLC is directly connected to AC network gets on.Two, CPU (CPU) CPU (CPU) is the control axis of programmable logic controller (PLC).The function that it is given according to programmable logic controller system program receives and stores user program and the data of keying in from programmable device; Check the state of power supply, memory, I/O and warning timer, and can diagnose the syntax error in user program.When programmable logic controller (PLC) puts into operation, first it receives state and the data of on-the-spot each input unit in the mode of scanning, and deposit respectively I/O image area in, then from user program memory, read one by one user program, after command interpretation, by the result of the regulation actuating logic of instruction or arithmetic operator, send in I/O image area or data register.After all user programs are finished, finally the data in each output state of I/O image area or output register are sent to corresponding output device, so circular flow, until out of service.In order further to improve the reliability of programmable logic controller (PLC), to large-scale programmable logic controller (PLC), also adopt two CPU to form redundant system in recent years, or adopt the voting formula system of three CPU.Like this, even if certain CPU breaks down, whole system still can normally be moved.Three, memory: the memory of storage system software is called system program memory.The memory of depositing application software is called user program memory.Four, input/output interface circuit: 1. on-the-spot input interface circuit is by the input interface circuit of optically coupled circuit and microcomputer, and effect is the input channel of the connection interface of programmable logic controller (PLC) and field control.2. on-the-spot output interface circuit is integrated by exporting data register, gating circuit and interrupt requests circuit, and effect programmable logic controller (PLC) is exported corresponding control signal by on-the-spot output interface circuit to on-the-spot execution unit.Five, functional module: as functional modules such as counting, location.Six, communication module.After programmable logic controller (PLC) puts into operation, its course of work is generally divided into three phases, i.e. input sample, user program execution and output refreshes three phases.Complete above-mentioned three phases and be called a scan period.During whole service, the CPU of programmable logic controller (PLC) repeats above-mentioned three phases with certain sweep speed.One, the input sample stage: in the input sample stage, programmable logic controller (PLC) in turn reads in all input states and data with scan mode, and they are deposited in the corresponding unit in I/O image area.After input sample finishes, proceed to user program execution and output and refresh the stage.In these two stages, even if input state and data change, the state of the corresponding units in I/O image area and data can not change yet.Therefore, if input is pulse signal, the width of this pulse signal must be greater than a scan period, and under any circumstance, this input all can be read into guarantee.Two, the user program execution phase: in the user program execution phase, programmable logic controller (PLC) always in turn scans user program (ladder diagram) by order from top to bottom.When each ladder diagram of scanning, always first scan again the control circuit being formed by each contact on the ladder diagram left side, and by first left and then right, first up and then down order, the control circuit consisting of contact is carried out to logical operation, then according to the result of logical operation, refresh the state of this logic coil corresponding position in system RAM memory block; Or refresh the state of this output winding corresponding position in I/O image area; Or determine whether to carry out the specific function instruction of this ladder diagram defined.In user program implementation, only have state and the data of input point in I/O image area can not change, and other output points and software state and the data in I/O image area or system RAM memory block all likely change, and arrange superincumbent ladder diagram, its program execution result can work to the every ladder diagram of using these coils or data coming below; On the contrary, come ladder diagram below, the state of the logic coil that it is refreshed or data can only arrive the next scan period and could work to row's program in the above.If use I/O instruction immediately in the process of carrying out in program, can direct access I/O point.Use I/O instruction, the value of input process shadow register can not be updated, and program is directly from I/O module value, and output procedure shadow register can be upgraded immediately, and this is with inputting immediately some difference.Three, output refreshes the stage: after scanning user program finishes, programmable logic controller (PLC) just enters output and refreshes the stage.During this period, CPU is according to state and all output latch circuits of Refresh Data corresponding in I/O image area, then drives corresponding peripheral hardware through output circuit.At this moment, be only the real output of programmable logic controller (PLC).Programmable logic controller (PLC) has following salient feature: one, system forms flexibly, and expansion easily, be take switching value control as its speciality; Also can carry out the pid loop of continuous process controls; And can form complicated control system with host computer, as DDC and DCS etc., realize the comprehensive automation of production process.Two, easy to use, programming is simple, adopts the programming languages such as simple and clear ladder diagram, logic chart or statement list, and without computer literacy, so system development cycle is short, field adjustable is easy.In addition, can online modification program, change control program and do not tear hardware open.Three, can adapt to various severe running environment, antijamming capability is strong, and reliability is strong, far above other various types.
