1、按性状分类：
1. Classification according to the characters:
（1）溶剂类金属除油剂，通常是指不溶于水，不能加水稀释的金属除油剂；传统所用的煤油、柴油、汽油、三氯乙烯、三氯乙烷、白电油等都属于溶剂类除油剂。
(1) the solvent metal deoiling agent usually refers to the metal deoiling agent that is insoluble in water and can not be diluted with water; the traditional kerosene, diesel, gasoline, trichloroethylene, three chloroethane, and white electric oil are all solvent deoiling agents.
（2）水基类金属除油剂是指可溶于水，可加水稀释的金属除油剂
(2) water based metal degreasing agent is a metal degreasing agent which can be dissolved in water and can be diluted with water.
2、按酸碱度分类：
2. Classification according to acidity and alkalinity:
（1）酸性金属除油剂，是指PH值低于7的除油剂，
(1) acidic metal degreasing agent is an oil removal agent whose pH is less than 7.
（2）中性金属除油剂，是指PH值约等于7的除油剂；
(2) neutral metal degreasing agent refers to degreasing agent whose pH is equal to 7.
（3）碱性金属除油剂，是指PH值大于7的除油剂，
(3) alkaline metal degreasing agent is an oil removal agent whose pH is greater than 7.
3.按温度分类：
3. according to the temperature classification:
(1) 常温金属除油剂；
(1) metal deoiling agent at normal temperature;
(2)中温金属除油剂；
(2) medium temperature metal deoiling agent;
