由于塑料有很多优点,它的使用范围不断扩大,在工程上已代替了部分金属。因此,加工塑料的方法也日益引起重视。目前用的手工锯和机械锯,缺点是劳动强度高、费料、费时并产生有害气体和粉尘,污染环境,影响职工身体健康。现介绍一种经常温处理再切割的方法,其效率比手工锯切提高六百倍,比机械圆锯切割提高三百倍,切割时无切屑、噪音,有利于环境卫生。其方法是:
Due to the many advantages of plastic, its use has been expanding and has replaced parts of the metal in engineering. Therefore, the processing of plastic methods are also increasingly attention. The current hand saws and mechanical saws, the disadvantage is the high labor intensity, costly, time-consuming and produce harmful gases and dust, pollute the environment, affecting the health of workers. Is now introduced a method of re-cutting at room temperature, the efficiency of six hundred times more than manual sawing, cutting three hundred times more than mechanical circular saw cutting no chip, noise, is conducive to environmental health. The method is:
