        摘要：There are large rape growing areas in southern and south western China so that it is very meaningful in making particleboard from rape stalk,which to ease the lacking of wood material.Experiment results showed that mechanical and physical properties of the board were able to meet the demand of GB/T 4897—92.But conventional manufacturing technology of particleboard had to be adjusted and improved because physical and chemical characteristics of rape stalk were different from that of wood material,such as,pH value and buffer capacity of the rape stalk were higher than that of wood.Technology of tackling with the side effects derived from the raw material was also developed.

        摘要：In order to elucidate surface performance of wood treated by microwave plasma,surface wettability of wood both untreated and treated by plasma were studied by measuring contact angles of liquid water and variance of the surface was observed with SEM.Results showed that the contact angle decreased to zero after treated by microwave plasma,even if the treated condition was very weak.This indicated that wood wettability increased strongly by plasma treatment.A coarser surface caused by ablating was observed under SEM after treated by plasma.The coarse surface could possibly increase the wettability of wood surface.

        摘要：This paper analyses effects which influenced homogeneity of fiber gypsum blending and mat forming.The results were as follows:both of the blender and mat former used in this experiment had good performance and the quality of mixture and mat forming was satisfied.The piling height of fiber gypsum mixture in the bin had obvious influence on uniformity of the mat density represented by good linear relationship between the mat density and the piling height of the mixture.The board density had good linear relationship with MOR and MOE ,but had poor linear relationship with IB .The MOR,MOE ,and IB were getting higher with the board density increasing.

        摘要：Veneer gluability and the gluing technology for 6 poplar varieties were studied by means of orthogonal experimental design with assembly pattern,resin consumption,adhesive formulation,and hot pressing technology as influencing factors.It was found that it was difficult to develop a set of universal gluing technology for all of the poplars tested because of the remarkable variation in wood properties among them.However,higher bonding strength could be obtained with pressing pressure of 0.5 to 0.8 MPa,pressing time of 40 s/mm,UF resin consumption of 280 to 340 g/m 2,additive ratio of 15 between wheat flour and resin,and assembly pattern of constant thickness in most cases.The Populus deltoides barter.CV.‘Lux’(Ⅰ 69/55) and P.×euramericana Guineir CV,‘San Martino’(Ⅰ 72/58)were easy to glue.The P.bolleana L.within the sect. Populus had the lowest pH value and buffering capacity,and therefore could be well glued without any special consideration.The P.cathayana Rehd.,P.simonii Carr.,and P.gansuensis C.Wang et H.L.Ying within sect. Tacamahaca had higher pH value and buffering capacity,and therefore the glue shear strength was not able to reach the Chinese National Standard’s requirement unless appropriate conditions were adopted.
