Products wood fibers (xylem fiber) is a natural renewable the timber after chemical treatment, mechanical processing of organic flocculent fiber material. Non-toxic, tasteless, non-polluting, non-radioactive. The product properties due to the capillary action of the fiber structure, the water inside the system is rapidly transferred to the surface of the slurry and the interface, so that the slurry inside the uniform distribution of water significantly reduced skinning. And so that the adhesive strength and surface strength was improved, this mechanism is also due to the reduction in tension in the drying process obviously play the role of of crack resistance. Dimensional stability and thermal stability of the wood fiber insulation materials played a very good thermal insulation concrete cracking. Has excellent flexibility and decentralized functional use of lignocellulosic mixed to form a three-dimensional network structure and enhanced support force and endurance of the system, and can improve system stability, strength, density and uniformity. Note wood fibers structural viscosity, so that the uniformity of the processed precast slurry (dry and wet material) to remain stable and to reduce the contraction and expansion of the system, greatly improved the accuracy of the construction or the preform.
