Trichloroisocyanuric acid is one of the chlorinated isocyanuric acid series products, referred to as TCCA. The pure product is powdery white crystal, slightly soluble in water, and easily soluble in organic solvents; The active chlorine content is 2 to 3 times higher than that of bleaching powder. Trichloroisocyanuric acid is an updated product of bleaching powder and bleaching spirit. The three wastes are greatly reduced compared with bleaching spirit. There is a trend in advanced countries to use it to replace bleaching spirit.

FAQ

What is the action mechanism of Trichloroisocyanuric acid?

Trichloroisocyanuric acid belongs to chlorinated isocyanuric acid esters and is a chlorinated derivative of isocyanuric acid. Its disinfection mechanism: dissolves in water to produce hypochlorous acid with microbial killing activity. Hypochlorous acid has a small molecular weight and is easy to spread to the surface of the bacteria and penetrate the cell membrane into the bacteria, causing the bacteria to oxidize the protein and cause the death of the bacteria.
