热压工艺对木塑复合板表面性能及稳定性的影响
Effects of hot pressing process on surface performance and dimensional stability of wood-plastic composite plywood
摘要
Abstract
Chinese fir veneer was rolled out of the hole,and combined with high density polyethylene(HDPE)film to produce non-formaldehyde wood-plastic composite plywood(WPCP).The effects of hot pressing technology(hot pressing temperature,hot pressing pressure and hot pressing time)on the surface properties and dimensional stability of WPCP by testing the surface contact angle,water absorption,and thickness swelling ratio of 2 h and 24 h.The results showed that hot pressing technology had influence on the contact angle and dimensional stability of WPCP,and the hot pressing temperature and hot pressing time have an obvious effect on the contact angle.When the temperature increased from 160℃ to 205℃,the contact angle increased rate 169％compared to reference sample;when the hot pressing time increased from 5 min to 12 min,the contact angle increased rate 146％;the effect of hot pressing pressure on the contact angle was not obvious.In addition,the impact of hot pressing temperature,hot pressing pressure on the dimensional stability was significantly greater than hot pressing time.Taking surface finishing and the dimensional stability of WPCP into account,the optimized condition was hot pressing temperature of 175℃,hot pressing pressure of 1.2 MPa,hot pressing time of 10 min.关键词
