| 1、注意零件污垢的种类和性质 1. Pay attention to the type and nature of parts dirt. 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 on automobile parts vary greatly, including oil, dirt, carbon deposit, rust and other solid oil and grease residues. Scale and rust can be removed by acidic degreasers; the carbon deposit is hard and has strong adhesion. Only a few degreasers can be removed, such as heavy oil cleaner. 2、防治零件被腐蚀 2, prevention and control parts are 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, aluminum and other easily corroded parts and precision instruments, instrument parts, etc., to choose near neutral, less corrosive, strong anti-corrosion deoiling agent, such as precision parts cleaning agent. 3、要考虑除油条件 3, 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, high temperature oil removal agent can be used. 4、注意除油剂的的浓度 4. Pay attention to the concentration of degreasing agents. 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 deoiling agent has a great relationship with the deoiling effect. Generally, with the increase of the concentration, the deoiling ability is also enhanced. However, when the concentration reaches a certain level, the deoiling ability is not significantly improved. 5、要掌握除油剂温度 5. Master the temperature of degreasing 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 Generally speaking, with the increase of the temperature of the degreaser, its decontamination ability also increases, but when the temperature exceeds a certain value, the decontamination ability will decrease. Also, be careful not to use degreasing agents under super cold conditions. 6、掌握除油剂的使用时间 6. Master the use time of degreasing agents. 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 deoiling agent can be used many times at a time, and its use time mainly depends on the number of deoiling parts and the degree of deoiling agent pollution. In general, the degreasing agent can be used for two weeks in a continuous manner. In order to save the use of deoiling agent and improve the quality of deoiling agent, the deoiling sequence should be reasonably arranged according to the characteristics of parts. 7、使用酸性除油剂时一定注意安全 7, pay attention to safety when using acidic degreasing agent. 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。 The popular degreasers on the market now are harmless to the body, but after all, it is a chemical product, if accidentally into the eyes, will also cause varying degrees of injury. If splashes into the eye carelessly applies the massive clear water flushing, the non-operation personnel is far away from the work environment and the chemical liquid storage place. |
