三氯异氰尿酸 结构式

Trichloroisocyanuric acid (TCCA) is a strong oxidant and chlorinating agent which has efficient, broad-spectrum, and safe disinfection effects. It has the strongest bactericidal activity among chlorinated isocyanuric acid products against bacteria, viruses, fungi, mold, Vibrio cholerae, Bacillus. It also has certain inhibitory effect on coccidia oocysts and thus can used in the disinfection in the environment, drinking water, fruits and vegetables, livestock feeders, fish ponds and silkworm rooms.

TCCA has an excellent bactericidal property and is a new generation of broad-spectrum, high efficiency, low-toxicity fungicides, bleacher and anti-shrinking agent. It is mainly used in the disinfection and sterilization of drinking water, industrial water recycling, swimming pool, restaurants, hotels, public places, homes, hospitals, eggs and prevention of fish diseases. It has a killing effect on almost all fungi, bacteria, viruses, and spores. It is safe and convenient to use. This product can also be widely used in food, dairy, rice seed processing, fruit preservation, fiber bleaching, wool shrink, daily chemical decolorization, wood mold paper making, rubber oxidation and battery materials.

1. Swimming pool disinfection: calculate the usage according to 2-3g/m3; take effect for 30-60 minutes.

2. Public places and ground disinfection: use 1500-3000-fold diluted water solution for spraying and wiping for 30 minutes. Infectious disease epidemic area, use 150-200-fold aqueous diluted water solution for spray disinfection.

3. Disinfection of white clothing and blankets: apply 2000-3000 fold diluted solution for clean items; soak for 10 minutes; for seriously polluted items, diluted 500 times, soak for 20 minutes.

4. Disinfection of bathroom and toilet scrub; use 300-fold diluted solution for reaction of 30 minutes.

5. Sterilization of non-metallic medical equipment: use 500-1000 times diluted solution for soak of 30 minutes; disinfection of apparatus with pus and blood; apply 100-fold diluted water solution for reaction of 30 minutes.

6. Disinfection of non-metallic tableware: use 500-1000 times diluted water solution for reaction of 30 minutes.


Application in printing and dyeing industry

Trichloroisocyanuri acid contains up to 90% active chlorin and is used as a bleaching agent in the printing and dyeing industry. It is suitable for bleaching of cotton, linen, wool, synthetic fibers and blended fibers. Not only does it not damage the fibers, but its performance is better than that of sodium hypochlorit and bleaching essence, and it can be used instead of imported sodium hypochlorit.

Applications in the food industry

Instead of chloramine T for food disinfection, its effective chlorin content is three times that of chloramine T. It can also be used as a decolorizing and deodorizing agent for dextrin.

Application in wool textile industry

In the wool textile industry, it is used as an anti-shrinkage agent for wool instead of potassium bromat.

Applications in the rubber industry

It is used as a chlorinating agent in the production of rubber industry.

Used as an industrial oxidant

The oxidation-reduction electrode potential of trichloroisocyanuri acid is equivalent to hypochlorite, which can be used as a high-quality oxidant instead of hypochlorite.

other aspects

It is used as a raw material in the organic synthesis industry to synthesize various organic compounds such as tris(2-hydroxyethyl) isocyanurate. Cyanuric acid, the product of the decomposition of trichloroisocyanuri acid, is not only non-toxic, but also has a variety of uses, such as the production of a series of resins, coatings, adhesives, plastics.
