1、按性状分类： 1, according to character classification: （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；如裕满实业替代三氯乙烯替代品FRB-1.1，碳氢清洗剂FRB-101、FRB-111、FRB-121、FRB-122，白电油替代品FRB-1.1F、FRB-662、FRB-663；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) solvent metal degreasing agent, usually insoluble in water, not water metal degreasing agent diluted; such as the margin of the full industrial substitute TCE substitutes FRB-1.1, FRB-101, FRB-111, hydrocarbon cleaning agent FRB-121, FRB-122, white oil replacement for FRB-1.1F, FRB-662, FRB-663; the traditional use of kerosene and diesel, gasoline, trichloroethylene, trichloroethane, three white oil belong to solvent degreasing agent. （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，如裕满实业高效水基除油剂WP-751、中性除油剂WHC-1、弱碱性除油剂WHC-2、碱性除油剂WHC-5、酸性除油剂WP-20等属于水基类除油剂。 (2) the water-based metal degreasing agent is soluble in water, the water can be added in metal degreasing agent dilution, such as Yu full industrial high efficient water-based degreasing agent WP-751, neutral oil removal agent WHC-1, alkaline degreasing agent WHC-2, alkaline degreasing agent WHC-5, acidic degreasing agent WP-20 to water-based removal oil agent. 2、按酸碱度分类： 2, according to acid-base classification: （1）酸性金属除油剂，是指PH值低于7的除油剂，如裕满实业酸性除油剂WP-20 PH值为6.5； (1) acidic metal degreasing agent, refers to the pH value of less than 7 of the degreasing agent, such as Yu full industrial acid degreasing agent WP-20, pH value of 6.5; （2）中性金属除油剂，是指PH值约等于7的除油剂，如裕满实业中性除油剂WHC-1 PH值为7； (2) neutral metal degreasing agent, refers to the pH value of about 7 of the degreasing agent, such as Yu Jie industrial neutral degreasing agent WHC-1, pH value of 7; （3）碱性金属除油剂，是指PH值大于7的除油剂，如裕满实业弱碱性除油剂WHC-2 PH值9、水基除油剂WP-751 PH值为11。 (3) alkaline metal degreasing agent, refers to the pH value greater than 7 of the degreasing agent, such as Yu industry, weak alkaline oil removal agent WHC-2, pH value 9, water-based degreasing agent WP-751, pH value of 11.
