摘要

本研究探讨了用异氰酸酯胶粘剂制造低密度杉木刨花板的工艺条件 ,讨论了施胶量、热压温度、热压时间、热压压力和刨花含水率对板材性能的影响。结果表明 ,当板材密度为 0 .43～ 0 .48g/ cm3时 ,施胶量只需 5 % ,刨花含水率适应范围广 ,所制成的刨花板无毒 ,耐水性好

Abstract

This paper studies the technology for making nonpoisonous low density Chinese Fir ( Cunninghamia lanceolata) particleboard with diisocyanate adhesive. The effects of adhesive consumption, hot pressing temperature,time and pressure of hot pressing, moisture content of particles on properties of board were discussed. The result showed,when the density of board was 0.43～0.48 g/cm 3, the adhesive consumption was only 5%. Particles with moisture content lower than 25% were suitable for use. The manufactured particleboard was nonpoisonous with good water resistance.
