Skill.
Background technique
Heavy bamboo floor is commonly called as bamboo filament plate, is one of bamboo flooring, it is further complete on the basis of general bamboo flooring
It is kind, so that its is more attractive and more practical.The selection of this bamboo flooring is finer than general bamboo flooring selection, its general selection
Local 4 years or more the high-quality moso bamboos in bamboo age or other bamboo kinds with similar material do material, through selection, carbonization (or boiling),
A series of strict technology processes such as drying and cold pressing (or hot pressing) produce.Heavy bamboo floor density is high, more than common bamboo flooring
It is wear-resisting, and it is smooth it is smooth, moth, indeformable and color be not graceful, while texture is clearly pleasing, is other any floor institute nothings
As method ratio, it is practically applicable to high-end residential, office, bedroom, hotel, sport place and outdoor leisure.
Heavy bamboo floor is divided into hot pressing heavy bamboo floor and cold pressing heavy bamboo floor.Hot pressing heavy bamboo floor is by bamboo wood drying, impregnation
And drying, and be heating and curing primary completion being not required to die-filling lower direct tiling pressure, it breaks and cuts after blank molding, do water balance
Complete blanket, then japanning.Cold pressing heavy bamboo floor is then to do suitable bamboo silk drying again to the following impregnation of lower moisture content
Dry, die-filling and assembly pressure puts to heat cure in constant temperature space after locking, breaks and cut after blank molding, do water balance, thus
Blanket is completed, the line that can paint does finished product.It can be seen that hot pressing heavy bamboo floor and cold pressing heavy bamboo floor are only being suppressed
Have larger difference during at blanket, the process being further processed on it after blanket is made is almost the same, be hacking,
Sanding, fluting and japanning and etc..So the processing of existing many producers transport and later period differentiation for convenience, it all can be with
Blanket is bought and sold as intermediate products, i.e., produces heavy bamboo blanket by way of hot pressing or cold pressing and sold, i.e. hot pressing
Heavy bamboo blanket and cold pressing heavy bamboo blanket, are processed after buyer buys heavy bamboo blanket, again thus according to the design scheme of oneself
Carry out differentiation production.

The requirement of anticipation is often not achieved in the density at the edge of thermally expandable sheet, is easy paralysis side, be easy to cause the density unevenness of plate.To produce
It is higher to occur cracking, the probability of the jump bad phenomenons such as silk and deformation after raw plate face japanning.The advantages of hot pressing is: hot pressing is with reference to cold
Certain deficiencies of pressure, in conjunction with the improved technique of production technology of bamboo slab rubber maturation, press the primary completion that is heating and curing, blank at
Type process is to complete to be heating and curing under the pressure of a few kiloton, even density, is not easy paralysed side and jumps silk, solves the inherence of slab
Quality problems have further raising；The shortcomings that hot pressing is: the opposite cold pressing of the density of hot pressing heavy bamboo floor wants high, broken to cut difficulty
Larger, consumables cost is also relatively high, and the opposite cold pressing of the time that hot pressing heavy bamboo is heating and curing shorter color difference is much bigger.
Under the prior art because the difficulty of hot pressing processing is greatly and high lossy, while again because cold-press process simple and
It is readily achieved, so, more and more producers tend to the processing technology of selection cold pressing, but the cold moudling of existing heavy bamboo blanket
Exist in production technology and be easy to appear paralysed side, is i.e. cold presswork is uneven, so as to cause cracking, jumps the bad phenomenons such as silk and deformation
