1.正确配制清洗液一般要求配制的浓度为3～5%。如果去污慢,可以延长浸泡时间、改进清洗方法或提高温度等,以达到理想的清洗效果。配制清洗液时,通常采用称重法,即将水(井水、河水、自来水都行)和清洗剂分别按浓度要求的数量,称重后倒在一起搅拌均匀。2.掌握好清洗温度实践表明对清洗液加热,清洗效果较好。一般可加热到20～70℃。加热方法有水蒸气加热、电加热和
1. Proper preparation of cleaning solution generally requires the preparation of the concentration of 3 to 5%. If the decontamination slow, you can extend the soaking time, improve the cleaning method or increase the temperature, in order to achieve the desired cleaning effect. Preparation of cleaning fluid, usually using the weighing method, the water (well water, river water, water are OK) and cleaning agents, respectively, according to the concentration of the required amount, weighing down and stir together. 2. Grasp the cleaning temperature practice shows that the cleaning fluid heating, cleaning better. Generally can be heated to 20 ~ 70 ℃. Heating methods are steam heating, electric heating and
