摘要

通过用稻草代替木材制造脲醛树脂胶稻草中密度纤维板的可行性研究 ,探讨了板材密度、施胶量和防水剂等工艺因素对稻草中密度纤维板性能的影响。结果表明 :在实验室条件下 ,当板材名义密度为 0 .8g/ cm3和施胶量为 17%时 ,脲醛树脂胶稻草中纤板性能达到现行国家标准一等品的要求 ;施加 1.2 %的石蜡乳液 ,板材的耐水性亦能满足国标要求

Abstract

The feasibility of medium density fiberboard （MDF） manufactured from rice straw with urea formaldehyde （UF） resin was investigated and the effects of board density, resin consumption and water repellent on properties of the board were also studied. Results showed that the properties of rice straw MDF with UF resin could meet the requirement of GB/T 11718 1999 when the board density was 0.8 g/cm 3 and resin consumption equaled 17%. Thickness swelling of board was improved greatly when water repellent was added at 1.2%.
