非水系工业清洗剂、不溶于水，不能加水使用的工业清洗剂；

如碳氢清洗剂、白电油替代品、三氯乙烯替代品等都属于此类。

传统常用的溶剂工业清洗剂有以下几类：烃类类：如煤油、柴油、汽油、环保碳氢清洗剂等；氯代烃类：如三氯乙烯，二氯甲烷以及四氯乙烯等；

酸性工业清洗剂，是指PH值低于7的工业清洗剂，如酸性水基清洗剂WP-20PH值为6.5；

中性工业清洗剂是指PH值约等于7的工业清洗剂，如中性清洗剂WHC-1PH值为7；

碱性工业清洗剂是指PH值大于7的工业清洗剂，如弱碱性水基清洗剂WHC-2碱性玻璃清洗剂WSG-130PH值均为9，碱性水基清洗剂WP-751、WHC-5、碱性光学玻璃清洗剂WSG-100PH值均为11。

Non aqueous industrial cleaning agents, industrial cleaning agents that are insoluble in water and cannot be added with water;

Such as hydrocarbon cleaning agents, white oil substitutes, trichloroethylene substitutes, etc.

The traditional commonly used solvent industrial cleaning agents include the following categories: hydrocarbons: such as kerosene, diesel, gasoline, environmental protection hydrocarbon cleaning agents, etc; Chlorinated hydrocarbons: such as trichloroethylene, dichloromethane and tetrachloroethylene;

Acidic industrial cleaning agent refers to the industrial cleaning agent with pH value lower than 7, such as acidic water-based cleaning agent wp-20with pH value of 6.5;

Neutral industrial cleaning agent refers to the industrial cleaning agent with pH value of about 7, such as neutral cleaning agent whc-1ph value of 7;

Alkaline industrial cleaning agent refers to the industrial cleaning agent with pH value greater than 7, such as weak alkaline water-based cleaning agent whc-2, alkaline glass cleaning agent wsg-130ph value is 9, alkaline water-based cleaning agent wp-751, whc-5 and alkaline optical glass cleaning agent wsg-100ph value are 11.
