本试验以生长在内蒙古西部沙漠地区的沙柳为原材料,以脲醛树脂胶(UF)和环保阻燃胶(KF)为胶粘剂,通过调整施胶量、胶液配比(KF/UF)、热压温度、热压时间等因素制取E1级沙柳材刨花板,并对刨花板的性能和效益进行分析。通过本次试验得出的生产E1级沙柳材刨花板的最佳施胶量9%,胶液配比(KF/UF)2:10,热压压力为1.5MPa,热压温度为180℃,热压时间为300 s。所研制的E1级沙柳材刨花板生产成本低,各项性能良好。
Using Salix trunk in desert of the western Inner Mongolia as raw material and urea formaldehyde(UF) and BL-formaldehyde Scavenger(KF) as adhesive,this paper studied on the class E1 Salix Particle Board by means of adjusting rate of spreading,ratio of one kind of glue to the other,namely KF to Urea formaldehyde,pressing temperature,pressing time and etc.We mainly make research on the effect of rate of spreading,ratio of different glue,that's say,the ratio of KF to Urea formaldehyde,pressing temperature,pressing time on free formaldehyde content,modulus of rupture,internal bond and fire-proofing property of board in the experiment.As far as the production of class E1 board is concerned,the best figure of rate of spreading and ratio of different glue is 9 percent and 20 percent respectively.Also,the best hot-pressing condition includes pressing force of 1.5MPa,pressing temperature of 180℃ and pressing time of 300s.The development of the E1 class Salix particleboard production cost is low,the performance is good.
