一、清除油污1.用碱性溶液除油。对钢铁零件表面的动植物油脂和矿物油指的清除,可采用碱性溶液加入少量乳化剂,经加温后清洗。若采用压力喷射,除油效果更佳。清洗完后,应用加热的清水喷射,冲洗掉零件表面残留的碱溶液。2.用有机溶剂除油。为防止碱溶液对精密零件(如高压油泵、喷油器等)的强烈腐蚀,一般可采用有机溶剂,如汽油、煤油、柴油、
First, clear the oil 1. With alkaline solution degreasing. On the surface of the steel parts of animal and vegetable oils and mineral oil refers to the removal of alkali solution can be used by adding a small amount of emulsifier, after heating cleaning. If the pressure jet, degreasing effect is better. After cleaning, the application of heated water jet, rinse off parts of the surface residual alkali solution. 2. Degreasing with organic solvent. In order to prevent alkali solution on the precision parts (such as high pressure pumps, injectors, etc.) of the strong corrosion, the general can use organic solvents, such as gasoline, kerosene, diesel,
