酸性除油剂和碱性除油剂哪个好用
Which is the best use of the acid deoiling agent and the alkaline degreasing agent
酸性除油其实是酸腐蚀金属，对除油有两个促进作用：1.随着金属表面被腐蚀，黏附于金属表面上的油污也随金属离子脱落进入除油剂中；2.酸腐蚀金属产生的氢气会促使表面的油污脱落进入除油剂中。
Acid deoiling is actually acid corrosion metal, which has two promoting effects on oil removal: 1. as the metal surface is corroded, the oil that adhered to the metal surface also falls into the degreasing agent with the metal ions falling off; and the hydrogen produced by 2. acid corrosion metal causes the surface oil pollution to fall into the degreasing agent.
从以上分析可以看出，当油污较重或者滴落点高时，酸性脱脂剂无法除掉油污。总体来看，碱性除油剂远远好于酸性除油剂。
From the above analysis, it can be seen that when the oil is heavy or dropping high, the acid degreasing agent can not remove the oil pollution. Generally speaking, the alkaline degreasing agent is far better than the acid degreasing agent.
