TCCA Granular

TCCA 90 granular is a very strong oxidant and chlorinating agent. It has a high-efficiency, board-spectrum and relatively safe disinfection effect. Among chlorinated isocyanuric acid products, it has the strongest bactericidal ability and has a killing effect on bacteria, viruses, fungi, molds, Vibrio cholerae, spores, etc., as well as a certain killing effect on coccidian oocysts. TCCA granular can be used for the disinfection of environment, drinking water, fruits and vegetables, livestock and poultry feeding troughs, fish ponds, silkworm houses, etc.

TCCA chlorine has the effects of killing algae, deodorizing, purifying water and bleaching. It has stronger sterilization and bleaching functions than sodium dichloroisocyanurate. It can be widely used as washing and bleaching agent for cotton and hemp synthetic fabric, wool shrinking-proofing agent. TCCA granular can also be used for rubber chlorination, oil drilling mud sewage sterilization treatment, battery materials. In water treatment field, it is suitable for swimming pool disinfection, drinking water disinfection, industrial sewage and domestic sewage treatment. In addition, as a powerful disinfectant, TCCA 90 granule can be used in food processing industry, food hygiene industry, aquaculture industry, daily chemical industry, hospitals, nursery, epidemic prevention, garbage disposal, hotels, restaurants, etc…

The working principle of TCCA granular is to slowly hydrolyze in water to generate cyanuric acid and hypochlorous acid.

Hypochlorous acid acts as an oxidizing bactericial and algaecide in water. And cyanuric acid can be used as a stabilizer of hypochlorous acid. Hypochlorous acid is a very strong oxidant. It can easily pass through the cell wall of microorganisms, and then combine with the protoplasm in the cell wall, destroy cell proteins and form stable nitrogen-chlorine bonds. Meanwhile, it can also oxidize the sulfhydryl groups such as triose phosphate dehydrogenase and reduce the activity of reductase necessary for respiration.

When the concentration reaches a certain level, it can destroy the whole cell and kill microorganisms. Hypochlorous acid will also ionize into hypochlorite in water. The sterilization effect of hypochlorite is far less than that of hypochlorous acid. It is estimated that hypochlorite is 20 times less effective than hypochlorous acid. 

Therefore, the sterilization effect is ideal when the pH of the circulating water is between 6.5 and 7.5. In order to ensure the sterilization effect, the circulating water must maintain a certain amount of residual chlorine and a certain contact time. Generally, the residual chlorine content is maintained at 0.2-1.0m/L, and the contact time is maintained at 4h to meet the sterilization requirements.
