Abstract
The invention discloses a high-density phyllostachys pubessens fiberboard. The phyllostachys pubessens fiberboard is a bamboo plywood produced by using the concept of arranging phyllostachys pubessens fiber vertically and laterally for recombination. Phyllostachys pubessens fiber belongs to coarse fiber and has better tensile strength, and the high-density phyllostachys pubessens fiberboard produced by using the recombination of the phyllostachys pubessens has the following main characteristics: 1, the bamboo plywood is the recombination of phyllostachys pubessens fiber instead of the simple recombination of bamboo chips; and 2, the phyllostachys pubessens fiber material is formed by heavy lateral and vertical pressure simultaneously, and the density and the texture are both more uniform, thereby greatly prolonging the service life of the bamboo plywood.
Description
Technical field
The invention belongs to the production technical field of bamboo offset plate.
Background technology
Along with the bamboo offset plate pours in market, by increasing user's favor.The shortcoming of bamboo offset plate is also more and more obvious at present, (has only 0.7-0.9g/cm such as present bamboo offset plate global density is little
2), quality is loose, be very easy to distortion, cracking, thereby the scope of application is narrow.And, make that the bamboo offset plate of compacting is very easy to bubble, layering because moisture content is higher behind the preceding glue of initial rubber.
Summary of the invention
The present invention utilizes the mao bamboon fiber closely to arrange up and down and bamboo offset plate that the theory that reconfigures generates.The mao bamboon fiber belongs to crude fibre, and its tensile strength is better, and its main feature of high density mao bamboon fiberboard that we utilize the reorganization of mao bamboon fiber to generate is:
1, the bamboo chip reorganization on reorganization that is the mao bamboon fiber of this bamboo offset plate rather than the simple meaning.
2, make mao bamboon fiber billot be subjected to up and down weight moulding simultaneously, density and quality are all more even, have prolonged the service life of bamboo offset plate greatly.
Present bamboo offset plate is produced, because the bamboo plate billot is mainly stressed to be the top and bottom directions, from the mao bamboon fiber, the bamboo offset plate longitudinal direction of its extrusion is more loose, the thick more this phenomenon of bamboo offset plate is just obvious more, therefore can only suppress the thick bamboo offset plate of 5-30mm, and the very easy strain cracking of bamboo offset plate, waste of material is also very big.And side pressure is adorned in our present high density mao bamboon fiberboard utilization of inventing on heating platen method has well solved this problem, because the bamboo plate billot is simultaneously stressed in direction up and down, we can suppress the bamboo offset plate of thickness 30-80mm, and density, quality are all very even, have also significantly reduced raw-material waste.
In traditional bamboo offset plate is produced because the bamboo plate billot before glue behind the glue moisture content higher, cause in the bamboo offset plate pressing process and bubble easily, ftracture, had a strong impact on the quality of bamboo offset plate.High density mao bamboon fiberboard of the present invention has been controlled the moisture content behind the glue before the glue especially, thereby has well been solved this problem in manufacture process.
The present invention utilizes traditional bamboo offset plate production technology to do improvement slightly, make the mao bamboon fiber at high temperature, be subjected to high pressure to be pressed into thicker bamboo offset plate up and down simultaneously, then the bamboo offset plate with compacting dissects into multilayer, with the outer surface of the inner surface that dissects back formation as the bamboo offset plate.The high density mao bamboon fiberboard that has utilized the advantage of mao bamboon fiber to make fully has that density is big, quality evenly, not yielding, be difficult for advantages such as layering.Can be widely used in a plurality of fields such as floor, furniture panel, decorative panel, container panel.
Its production technology is similar to traditional bamboo offset plate production:
1, the bamboo plate of buying on the market through chip select, is used for carbonization earlier.
2, (size is approximately 2 * 20 * 1950mm) bamboo plate of selecting to be rolled into the silk sheet billot of machine direction fragmentation.
3, bamboo chip is put into carbide furnace and do surface treatments such as carbonization.
4, bamboo chip is put into drying room and dry, its moisture content is reached below 13%.
5, bamboo chip is placed on impregnation in the phenolic resins adhesive, after impregnation 6-10 minute bamboo chip is pulled out, drain, put into 50-70 ℃ of chain drying room again and dry, make its moisture content reach 10-12%.
6, the density by finished product bamboo offset plate is 1.1-1.3g/cm
3Calculate, weigh up an amount of bamboo plate billot, vertically orderly arrangement is put into multi-daylight press and is installed.
7, at first under the normal temperature state that main voltage rise is high and remain on 3-5Mpa, pressurize 15 minutes.
8, then in 15 minutes, the heating platen temperature is increased to 145 ± 3 ℃, will leads pressure and side pressure and all be increased to 8-12Mpa, heat-insulation pressure keeping 45-120 minute (adjusting to some extent) according to the thickness different time.
9, in 3-8 minute, be cooled to 30-50 ℃, release die sinking then.
10, with the bamboo offset plate longitudinal section that presses, make the bamboo offset plate of suitable thickness specification, the inner surface of its generation is done the outer surface of bamboo offset plate.
11, the bamboo offset plate that suppresses just draws high density mao bamboon fiberboard after health in 7-10 days processing under air themperature 20-40 ℃, the environment of humidity 30%-45%.
The high density mao bamboon fiberboard of making according to the method, density reaches 1.1-1.3g/cm
2, quality is even, and superficial makings is clear, is well suited for doing a plurality of fields such as floor, furniture panel, decorative panel, container panel.
Description of drawings
Accompanying drawing 1 is a high density mao bamboon fiberboard press device device simple diagram.Wherein compacting tool set consists of the following components: 1 is the side pressure cylinder, and 2 is side guide, and 3 are the side pressure square steel, and 4 are the side pressure block, and 5 is heating platen, and 6 is upper padding plate, and 7 is lower bolster.
