工程塑料在吉林省林业生产上的推广、应用是近年来涌现的新材料新技术。工程塑料通常是指热塑性塑料,它具有预应力应变性,在一些特殊环境下(如低温、腐蚀等)仍有优良性能,并有很好的抗张强度、剪切强度、韧性、刚性、容易加工,因而,在汽车、拖拉机、蒸汽机车上有着广泛的应用。它在一定条件下可以代替镍、铬、铜等稀贵金属。据有关部门计算,一吨尼龙可代替铅3.6吨,钢10.2吨,生铁9.8吨,青铜12.2吨,黄铜7.5吨,不锈钢7.8吨。同时,由于改变了加工工艺,节约了加工工时,降低了成本,具有显著的经济效果。
The promotion and application of engineering plastics in forestry production in Jilin Province is a new technology and new material emerging in recent years. Engineering plastics usually refers to the thermoplastics, which have the prestressing strain, in some special circumstances (such as low temperature, corrosion, etc.) are still excellent performance, and have good tensile strength, shear strength, toughness, rigidity, easy Processing, therefore, in cars, tractors, steam locomotive has a wide range of applications. Under certain conditions it can replace nickel, chromium, copper and other rare metals. According to the calculations of relevant departments, a ton of nylon can replace 3.6 tons of lead, 10.2 tons of steel, 9.8 tons of pig iron, 12.2 tons of bronze, 7.5 tons of brass and 7.8 tons of stainless steel. At the same time, due to changes in the processing technology, saving processing time, reduce costs, with significant economic effects.
