Specification of wood cubes

(1) the effect on the permeability of wood. According to research, Xing'an larch heartwood contains arabinogalactan 8.73% sapwood contains 5.75%, a large number of distribution in the cavity of the tubular cells, seriously impede the internal moisture in the form of liquid to the wood to the external diffusion and anticorrosion and other modification of the liquid by the surface of the wood to the internal infiltration, which led to the larch wood is difficult to dry easy to crack and due to the difficulty of impregnation and the effect of modification treatment is not good.

(2) the impact on the wood pulp process. Larch wood is the main raw material for pulp and paper making, during the cooking period the arabinogalactan contained in the wood consumes a large number of cooking chemicals, affecting the quality of pulp; at the same time, due to its own hydrolysis, increasing the content of monosaccharides and organic acids in the black liquor of the pulp, exacerbating the environmental pollution.

(3) the cement curing effect. In the cement wood manufacturing process, cement is the adhesive of the wood. However, the cement itself does not have adhesive effect, only after the formation of hydration crystallization has adhesive force and overall strength, so the good and bad crystallization is directly related to the quality and performance of cement particle board. The experimental results proved that larch arabinogalactan has serious adverse effects on the hydration and crystallization process of cement, which can delay the setting of cement and reduce the strength of cement curing wood.
