汽车零部件在机械加工、热处理、表面处理等生产过程中,产品必然会与酸、碱、盐等物质及汗渍接触,产生变色锈蚀或在加工表面形成腐蚀性隐患,从而影响产品的防锈和防锈封存质量。此外,产品在贮存、运输、销售环节中主机产品往往需要停放一段时间,处于日晒或风、霜、雨、雪的大气环境中,产品的外表面往往由于变色、起泡甚至锈蚀而失效。而像主离合器、转向离合器、轮辋、柴油泵的拉杆、柴油机的气门推杆等零部件,一旦锈蚀或卡死,就会严重影响主机性能,从而 Auto parts in mechanical processing, heat treatment, surface treatment and other production processes, the product will inevitably with acid, alkali, salt and other substances in contact with the perspiration, resulting in discoloration rust or corrosion in the processing of the formation of the surface, thus affecting the product rust and Rust-proof storage quality. In addition, the host products in the storage, transportation and sales processes often need to park for a period of time in the sun, wind, frost, rain and snow. The outer surfaces of the products often fail due to discoloration, blistering and even rusting. And like the main clutch, steering clutch, rims, diesel pump rod, diesel valve push rod and other parts, once the rust or stuck, it will seriously affect the host performance, which
