        摘要：In this paper the performance and bonding quality of urea formaldehyde resin specialized in low free formaldehyde content were studied. In the experiment, five species of poplar veneer were used for making 3 ply plywood. It was found that no matter whether the poplar veneer species were mixed or unmixed in assembling plywood a bonding strength according to National Standand could be obtained. The dosage of curing agent had considerable influence on the bonding strength property of poplar veneer.

        摘要：Oriented strand board(OSB) is one of the new types of high strength wood based panels. The analysis indicated that OSB had advantages such as suitable price, good market, flexible raw material resources and high investment benefit. However, the uses and market in China should be intensively studied.

        摘要：With wood raw materials treated respectively with NaOH and NaClo 2, parts of hemicellulose and lignin in wood removed. Compared to the binderless fiberboard made of untreated wood materials, both strength properties and water resistance of the boards made of the treated wood materials showed a significant decrease. The results indicated that both hemicellulose and lignin in wood have an important effect on the formation of self bonding of wood fibers.

        摘要：The influence of thickness and laying methods of poplar veneer on the performance of com ply with OSB as the core layer material was studied in this paper. It was found that: firstly, the strength and stiffness of the com ply in the two directions differed greatly from each other, when veneer grain was parallel to the orienting direction of the OSB, but became fairly even when perpendicular to each other; Secondly, the strength and stiffness of the com ply in the two directions were equal when the veneer was 0.85 mm thick and its grain was perpendicular to the orienting direction of the OSB.

        摘要：Methods to maximize wood surface hardness and wood dimensional stability inc lude various combinations of compression, heating, and chemical treatments. In this study, paulownia wood was treated with different concentration of low molecular weight(mol wt 350～380), water soluble melamine formaldehyde resin, being compressed while heated. The results showed that wood specimen treated with 6% resin solution retained almost complete fixation when soaked in room temperature water, while those treated with 25% resin solution retained fixation in boiling water. Moreover, the surface hardness increased from 0.122 MPa to 0.366 MPa when the wood was treated with 25% resin solution and 50% compression.

        摘要：This paper dealt with the relationship between hot pressing parameters and mechanical properties (MOR MOE and IB )of bamboo particle board by the orthogonal design method. The test results showed that the first phase pressure was the most important factor affecting the strength properties of bamboo particle board, hot pressing temperature and the first phase time also affected the strength properties, and the optimum hot pressing techno logy was obtained.
