        摘要：In this paper, properties of block board with cores made by 10 wood species from southern China were investigated. And the influence of these cores on properties of the block board was analyzed. The results of the study showed that even though the properties of these block boards could meet the demand of GB 5850-86, they behaved differently each other. The results also indicated that density, hardness and shrinkage of the core remarkably affected the properties of the block boards.

        摘要：In recent years, eucalyptus plantation is being developed very quickly in southern China and became an important raw material for industrial utilization. But it is necessary to determine the natural decay resistance, durability and ability of anti attack to pests. After both laboratory tests and field trials were applied, the results showed as follows: wood natural decay resistance of eucalyptus in 4～9 years after planted was relatively poor; most heartwood belonged to the moderate class, but sapwood all belonged to perishable class; the ability of wood anti attack to pests were relatively low as the wood was easy to be attacked by beetles and termites. The natural durable life of the Eucalyptus urophylla wood were slightly longer than half a year, and the wood belonged to non durable class.

        摘要：Wood density is considered as the most simple indicator of wood mechanical properties. It is widely recognized that there exists correlation between wood density and wood mechanical properties. However,it is difficult to compare with the data of wood density and mechanical properties from different countries for the different test methods being used. In this paper, conversion coefficients are presented for comparison between the data derived from Chinese Standards and American ones(ASTM).

        摘要：A treatment technology of black liquor and bleaching liquor from straw pulping process was studied in the paper. Firstly, the black liquor was treated by flocculation and filtration methods. And lignin and suspension solid etc were separated out. Then clear black liquor was mixed with bleaching liquor and treated with activated sludge process. The final flow had COD below 400 mg/L and could meet the demand of Chinese Pollution Effluent Standard in pulping process.

        摘要：With 2 coniferous tree species and 15 broad leaved tree species as testing material, an air seasoning test of lumber was carried out at Haikou region. 25 mm was chosen as main thickness of the lumber, and a small amounts of lumber with 15 and 50 mm in thickness were tested as well. The final moisture content of 20% was adopted while analyzing the data, and the following results were obtained: 1 In a year, the low drying rates occurred in Jan., Feb., Nov. and Dec.. So these months are not suitable for air seasoning of lumber in this region. 2 Among the species studied, Cyclobalanopsis patelliformis and Engelhardtia roxburghiana had lower drying rates (<1.0), Podocarpus imbricatus, Adinandra hainanensis, Artocarpus styracifolia and Schefflera octophylla , higher drying rates (2.1～3.0), and the other ten species, medium (1.0～2.0). 3 If the drying rate of 25 mm lumber was held as the base number of 1.0,the corresponding values were 2.2 and 0.3 for the 15 and 50 mm lumber, respectively. 4 An analysis of multiple regression showed that, in the process of air seasoning,the moisture content of wood was the most important factor affecting the drying rate of lumber, followed by the relative humidity and temperature. The effects of wind speed and atmospheric pressure were not significant. 5 Significant differences were found in equilibrium moisture contents among the difference wood species tested, but not the thickness of the lumber. The average EMC ofthelumbertested was 17.2%.

        摘要：This paper introduced a newly developed PF resin for particleboard manufacture specialized in low toxicity, high molecular weight and fast curing. The result shown that the curing speed of the resin was about 40% faster than that of commonly used PF resin. The properties of particleboard bonded with this resin reached German Standard DIN 68763 V100. The hot pressing time was reduced by about 25%, compared with that of commonly used PF resin.
