dichloro-1,3,5-triazinetrione - Application
Open Data Verified Data
dichloroisocyanate is similar to chlorine and is an oxidizing bactericide. The product can gradually release organic compounds of hypochlorous acid or chlorine in the circulating cooling water, and it can be used in the circulating cooling water system instead of liquid chlorine or hypochlorite. The dosing method is generally impact-type dosing in the catchment. The concentration of sodium dichloroisocyanurate was 25-50mg/L. When the circulating water containing hydrocarbons (oil) is not more than 5 mg/L, there will be better treatment effect. However, when the circulating water system water cooled medium leakage occurs serious, hydrocarbons or amines on the circulation of excessive water pollution, it will affect the product treatment effect.
