摘要
研究了以互花米草为原料的刨花板制造工艺,互花米草通过截断、再碎、干燥等加工制成工艺刨花碎料,以脲醛树酯为胶黏剂,采用正交实验设计,研究施胶量、热压温度、目标密度等工艺因素对刨花板主要物理力学性能(静曲强度、弹性模量、内结合强度、吸水厚度膨胀率)的影响,确定最佳热压工艺条件。研究表明:(1)互花米草可以用于刨花板制造;(2)脲醛树酯胶黏剂可以用于互花米草刨花板制造;(3)最佳工艺参数:施胶量12%、热压温度170℃、目标密度0.85。
This paper states the particleboard manufacturing process by truncating,broken,drying and other processes to manufacture shavings and scrap,using urea formaldehyde resin as the adhesive,adoping the orthogonal experimental design,researched the glue content,pressing temperature and other process factors on the physical and mechanical properties of particleboard including MOR,MOE,IB and TS in order to determine the optimum conditions for hot-pressing process.The results show that:1.Spartina can be used in particleboard;2.urea-formaldehyde resin adhesive can be used for rice straw particleboard;3.optimum process parameters:temperature hot glue content of 12%,target density 0.75170℃,there has a positive meaning for the rational use of spartina to explore processing particleboard.
