Higashihara et al.2000；Inoue et al.1993a；Inoue et al.1993b；Inoue et al.2008；
Ito et al.1998b；Kamke 2006；Kollmann 1936；Kollmann et al.1975；Navi and
Heger2004；Seborg et al.1945), the patent of timber densification also a lot (Sears, 1900；Walch and
Watts,1923；Oleheimer,1929；Brossmannes,1931；Esselen,1934；Olson 1934；Huang Rongfeng etc.
2011,2013).But due to many disadvantages, the industrial application of compacted wood or extremely limited.Main the having of these techniques
Learn method and machine method.The major defect of chemical method includes：
1) it cannot be guaranteed that timber natural characteristic；
2) influence timber is recycled or natural degradation again, and environment is polluted；
3) it is relatively costly.
Therefore, from the angle of environmental protection, physical mechanical method just more meets environmental protection concept of today.Existing machine in the world
The major defect of tool method includes：
1) complex process, the time is long；
2) several main methods being engaged in the laboratory of timber densification are limited to the examination of small size mostly in the world at present
Material；
3) the size resilience problem caused by Mechanical Method compacted wood；
4) some can reduce size resilience using high-temperature process (190~230 degrees Celsius) and sufficiently long time, and high temperature is long
Time-triggered protocol is damaged to Wood mechanical property, particularly wood surface, often results in partially carbonized, or causes color very
Deep and shade is widely different, generally allows compressed wood to use at all.
5) using high-temperature steam can alleviate above 4) in the subproblem mentioned, but because timber is in hot pressing iron plate high pressure
Under, steam is difficult uniformly (or even cannot) and is applied to the compression face of suppressed tree material, particularly when timber compression face is larger.
6) some hot presses steam fumarole (my previous experiments) are distributed with hot pressing iron plate and can alleviate above some
5) problem mentioned, can steam still cannot accomplish to be evenly distributed to compression wood surface, and timber under high pressure can be raised
To in spray orifice, many salient points are caused in compression wood surface.
Problems above all limits compressed wood application commercially in different degrees of and different aspect.Therefore have very much
Necessity continues to explore how to solve these problems.
Bamboo is one of renewable biological source important on the earth, and growth cycle is short, is become a useful person fast, has obtained big in recent years
Amount application.Bamboo wood has mechanical strength very high, and the elastic modelling quantity under its unit intensity can compare favourably with steel, however, bamboo
The density and mechanical strength of material horizontal (blue or green to tabasheer from bamboo) and longitudinal direction (vertical bamboo base portion to ending) are widely different, so as to cause
The integration engineering sheet material internal density and the highly non-uniform property of mechanical strength being made up of raw bamboo, it is impossible to and steel compare favourably, greatly
The big utilization for constraining raw bamboo.Separately, due to the circular arc of bamboo wall, in order to obtain the bamboo cane of rule, wave in bamboo chip process
Take substantial amounts of bamboo material.Although and common Recombined bamboo can obtain high density and relatively uniform sheet material, this kind of product is needed
A large amount of applying glues are wanted, pole is not environmentally.Above mentioned problem can be overcome by bamboo wood physicomechanical processes densification, it is possible to produce new height
Strength products, to bamboo wood using one new direction of developing..
