在伟大领袖毛主席“备战,备荒,为人民”的战略方针指引下,我国工程塑料在各个工矿部门中的应用,得到了迅速发展,取得了一定的成效。应用工程塑料,不但可以大量节约铜、镍、铬等贵重金属,而且是少、无切削加工的一项有效的技术措施,在某些方面塑料还是解决技术关键不可缺少的材料。同时我国石油工业的高速度发展和对工农业副产品的综合利用等,又为生产塑料提供了丰富的资源。目前,一个应用工程塑料的群众运动正在全国各地蓬勃开展。 工程塑料有很多优良的技术性能,例如重量轻、耐磨、抗震、耐腐蚀,有的还有自润滑性等。可用于制造各种机械零部件和管道,以代替钢材和有色金属。如塑料管道、塑料法兰、
Under the guidance of Chairman Mao's great leader, “preparing for war, preparing for war and for the people,” the application of engineering plastics in various industrial and mining sectors of our country has been rapidly developed and achieved some success. Application of engineering plastics, not only can save a lot of copper, nickel, chromium and other precious metals, but also less, no cutting of an effective technical measures, in some respects plastic or technology essential to solve the key material. At the same time, the rapid development of China's petroleum industry and the comprehensive utilization of the by-products of industry and agriculture provide rich resources for the production of plastics. At present, a mass movement using engineering plastics is booming throughout the country. Engineering plastics have many excellent technical properties, such as light weight, wear-resistant, earthquake-resistant, corrosion-resistant, and some have self-lubricating and so on. Can be used to manufacture a variety of mechanical parts and pipelines to replace steel and non-ferrous metals. Such as plastic pipes, plastic flanges,
