        摘要：This paper took a Chinese particleboard plant for example. A syste-malic tecknology investigation using raw material both from the plant and theWKI (Fraunhofer-Institute for Woodresearch) was carried out at the WK1.Theexperiment design and data calculation were processed with a statis tical me-thod.The results showed that the consumption of raw material could be de-creased, the quality of particleboard could be improved and the benefit could beincreased with some measures in the production prosess.Under certain technologyconditions, the binder consumption could be reduced by 30 percent.

        摘要：Method of test for toxicity of wood preservatives to soft-rot fun-gus was studied in order to establish standard method.The amount of decayand the loss in weight of test blocks of Chinese whip- poplar (Populus tomen-tosa)wood against soft-rot fungus was evaluated in laboratory. This methodwas adopted in the present study for the tests of toxicity of water borne andoil borne preservatives against soft-rot fungus-Chaetomium globosum.

        摘要：In this paper,some technical problems about the designing of en-ergy-saving furnace kiln were discussed,such as increasing selfproduced dra-ught force to improving ventilation;heating the stack by a combination of se-veral heat conduction ways; and reducing heat loss, Thus,the condition ofhigh speed drying and low energy consumption was reached。

        摘要：The feasibility of using hardboards for making concrete-form boardwas investigated. The combined effect of drying time after resin soaking,soaking time, ratio of resin to water, and hot,pressing pressure, time andtemperature on the properties of the concrete-form board was also studiedwith the orthogonal experiment. The concrete-form board was finally producedin one factorbased on the result.

        摘要：In this paper, the working circulations and evaluation methods ofhigh-temperature heat pump dehumidification,were presented. On the basis ofresearch and development of RCG30G high-temperature heat pump dehumidifierfor wood drying(HTHPD),a series of practical drying tests were performed.The results are as following:1.RCG30G HTHPD can save energy effectivelywhile drying timber, and also has advantages of high drying speed, good dry-ing quality and lower drying cost.2.Using the refrigerent R142b can raise thesupply air temperature (Max.> 70℃) ’ shorten the drying cycle and reducethe energy consumption and the ozonospheric disturbance.3.By drawing se-cond return air from the low temperature area of kiln into HTHPD, the heatloss of kiln was reduced greatly, meanwhile the air volume need of the con-denser can be met perfectly.
