| 金属除油剂应该注意的事项。 The metal deoiling agent should be paid attention to. 1、注意零件污垢的种类和性质 1. Pay attention to the types and properties of the fouling of parts 汽车零件的污垢种类和性质差异很大，有油污、水垢、积碳、锈迹等固相油污及润滑油脂的残留物。水垢和锈迹常用酸性除油剂可去除；积碳较坚硬，且附着力强，只有少数的除油剂可去除，如重油污清洗剂。 The types and properties of dirt in automobile parts are very different, such as oil pollution, scale, carbon, rust and other solid oil pollution and the residue of lubricating oil. The acid deoiling agent is often removed from the scale and rust. The carbon deposition is hard and the adhesion is strong. Only a few deoiling agents can be removed, such as heavy oil cleaning agent. 2、防治零件被腐蚀 2. Prevent the parts from being corroded 对于铜、铅、锌及铝等易被腐蚀的零件及精密仪器、仪表的零件等，要选用接近中性、腐蚀性小的、防腐蚀能力强的除油剂，比如精密零件清洗剂。 For copper, lead, zinc and aluminum and other easily corroded parts and precision instruments, instrument parts, etc., we should choose near neutral, corrosion-resistant, anti-corrosion ability of oil removal agents, such as precision parts cleaning agent. 3、要考虑除油条件 3, the oil removal conditions should be considered 若具备蒸汽加热的条件时，可选用高温型除油剂。 If the conditions of steam heating are available, the high temperature deoiling agent can be used. 4、注意除油剂的的浓度 4. Pay attention to the concentration of the degreasing agent 除油剂的浓度与除油效果具有很大的关系，一般随之浓度的增加，除污能力也相应增强，但达到一定的浓度时，除污能力不在显著提高。 The concentration of degreasing agent is closely related to the effect of oil removal. Generally, with the increase of concentration, the ability of removing pollutants is also enhanced. But when a certain concentration is reached, the ability of removing pollutants is not significantly improved. |
