机械加工是各行各业基础的基础,而机械加工中许多工序也存在不少污染问题,金属零部件在加工过程中由于生锈会给精度及下一道工序带来麻烦,一般都要上防锈油或脂,而下次加工时又要用清洗剂洗去防锈油或脂,有用汽油、二甲苯等有机溶剂清洗的,也有用洗涤剂清洗的,而汽油、废溶剂这些废液不仅存在有机溶剂污染问题,也会使人体中毒和引起火炎。在废液中处理汽油、柴油等有机溶剂很是不易,何况这些有机溶剂大都是石油提炼产品,本身就是能源。虽然这些防锈方法极不符合节能与环 Machining is the foundation of all walks of life, and many processes in machining there are many pollution problems, the metal parts in the process of processing due to rust will give rise to precision and the next procedure trouble, generally have to rust Oil or grease, and the next processing time with detergent to wash rust oil or grease, gasoline, xylene and other organic solvents, but also with detergent cleaning, and gasoline, waste solvents, these waste not only exist Organic solvent pollution problems, but also make the body poisoning and cause inflammation. It is not easy to dispose of organic solvents such as gasoline and diesel oil in waste liquid. Moreover, most of these organic solvents are petroleum refining products, and are energy sources in their own right. Although these rust-proof methods do not meet the energy-saving and ring
