dithiocyanomethane is a highly efficient, broad-spectrum bactericidal algicide, which has a high efficacy in killing the main bacteria, fungi and algae present in the circulating water, and the efficacy is maintained for a long time. As long as the concentration of 0. 3mg/L in water is maintained, it can effectively kill microorganisms. It is a non-oxidizing bactericide. The bactericidal and antibacterial effects of dithiocyanomethane are related to the pH value of water, and it has a good stable bactericidal effect in the range of pH 6~7. When the pH value is higher than 8.5, the decomposition is easy, and the sterilization effect is affected. Since dithiocyanomethane is insoluble in water and cannot be used directly, it is generally used in combination with solvents, dispersants or other bactericidal agents.
can cause eye damage and skin irritation, swallowing or adsorption is harmful and can even be fatal. Protection should be done to avoid contact with the skin. Keep away from heat and fire sources during storage and transportation.
