| 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. 5、要掌握除油剂温度 5. To master the temperature of the oil removal agent 一般情况下，随着除油剂温度的提升，其除污能力也随之提高，但超过一定温度后，除污能力反而会下降。同时要注意，不要在过冷的条件下使用除油剂 In general, with the increase of the temperature of the degreasing agent, the ability to depollution is also increased, but after a certain temperature, the ability of decontamination will decrease. At the same time, do not use the degreasing agent under the condition of too cold 6、掌握除油剂的使用时间 6. Mastering the use time of oil removing agent 一次配置的除油剂可以使用多次，其使用时间主要取决于除油零件的数量与除油剂污染程度。一般情况下，一次配置的除油剂可以连续使用两周的时间左右。为了节约除油剂的使用量，提高除油剂质量，除油时应该按照零件的特性，合理的安排除油顺序。 The oil removal agent in one configuration can be used many times, and its use time depends mainly on the amount of oil removal parts and the pollution degree of the deoiling agent. In general, a configuration of the oil removal agent can be used for about two weeks in a continuous period. In order to save the use of deoiling agent and improve the quality of the deoiling agent, the order of oil removal should be arranged reasonably according to the characteristics of the parts. 7、使用酸性除油剂时一定注意安全 7. Be sure to pay attention to safety when acid deoiling agent is used 现在市面上流行的除油剂都是对身体无害的，但它毕竟是化学产品，如不慎进入眼睛时，也会造成不同程度的伤害。如不慎溅入眼睛应用大量清水冲洗，非操作人员远离工作环境及化工药液存放处。 Now the popular oil removing agents on the market are harmless to the body, but they are chemical products after all. If they enter the eyes carelessly, they will also cause different degrees of injury. If inadvertently splash into the eyes and use a large amount of clean water, the non operator is far away from the working environment and the chemical liquid storage place. |
