在机器的摩擦部件上使用塑料具有重大的国民经济意义。木质塑料是一种利用预先浸渍有合成树脂的粉碎木材,通过热压方法制成的高强度的材料。由于它的机械强度高,摩擦系数低,耐磨性好,原料获取容易(木材),价格较低和制造工艺简单,因此木质塑料如像许多贵重的结构材料一样有着很重要的意义。但是,尽管木质塑料具有上述性能,却仍然没有获得普遍的使用;目前对它还很少研究,同时在制造
The use of plastic on the friction parts of machines has a significant national economic significance. Wood plastic is a high-strength material that is made by hot-pressing using crushed wood previously impregnated with a synthetic resin. Due to its high mechanical strength, low coefficient of friction, good abrasion resistance, easy access to raw materials (wood), lower costs and simpler manufacturing processes, wood plastic is as important as many valuable structural materials. However, despite the above-mentioned properties, woody plastics are still not universally used; little research has been done on it at the same time,
