First, the nature of the product:
Sodium dichloroisocyanurate is a high-efficiency, broad-spectrum, new systemic fungicide that kills a variety of bacteria, algae, fungi and germs. The product is chemically stable, easy to store and transport; safe, simple, low dosage and long lasting effect. The mechanism of action of Sodium dichloroisocyanurate is: Spraying on the surface of the crop can slowly release hypochlorous acid (HClO), by denaturation of the bacterial protein, changing membrane permeability, interfering with the physiological and biochemical system of the enzyme system and affecting DNA synthesis, etc. The pathogen died rapidly.

Second, the product uses:
Sodium dichloroisocyanurate for swimming pool water treatment, industrial circulating water algae removal. It is used for disinfection of tableware and disinfection, prevention of disinfection in families, hotels, hospitals and public places; environmental disinfection of breeding places in fish farming, sericulture, livestock, poultry and other breeding industries. Others, Sodium dichloroisocyanurate can also be used for textile bleaching, wool anti-shrinkage, paper tampering, rubber chlorination, battery materials, etc.

Wool anti-shrinkage treatment agent

The aqueous solution of Sodium dichloroisocyanurate uniformly releases hypochlorous acid, which acts on the protein molecules of the wool scale layer to destroy a part of the bonds in the wool protein molecule, thereby preventing shrinkage. In addition, the use of Sodium dichloroisocyanurate solution to treat wool products can also prevent the bonding of wool during washing, that is, the phenomenon of "pilling". The shrink-treated wool has almost no shrinkage, and the color is bright and the hand feels good. The wool can be immersed in wool or wool blended fibers and fabrics with 2% to 3% of Sodium dichloroisocyanurate solution and other additives. And its products can not afford the ball, not felt. Typical formulations are: (1) Sodium dichloroisocyanurate 0.5 parts (mass, the same below), 0.15 parts of acetic acid, 0.02 parts of humectant, 600 parts of water, 200 parts of wool fabric, soaking time at room temperature is 0.5h; (2) Sodium dichloroisocyanurate 0.5 parts, 0.15 parts of peracetic acid, 0.02 parts of humectant, 600 parts of water, and 200 parts of wool fabric.

Textile industry bleaching

In the textile industry, Sodium dichloroisocyanurate is mainly used as a bleaching agent for natural and synthetic fibers. Bleaching of natural and synthetic fibers destroys the pigments contained in the fibers. Sodium dichloroisocyanurate can produce hypochlorous acid in water. Hypochlorous acid can react with the conjugate bond of the chromophore in the fiber to change the wavelength of light absorption by the fiber and destroy the pigment in the fiber to achieve the purpose of bleaching. Compared with traditional bleaching agents, Sodium dichloroisocyanurate has many unique advantages. For example, general bleaching agents are required to be used at higher temperatures, while high temperatures exacerbate the bleaching agent's erosion of fibers and reduce the strength of fibers, while Sodium dichloroisocyanurate Good bleaching effect even at lower temperatures; in addition, bleaching natural and synthetic fibers with Sodium dichloroisocyanurate not only has good bleaching effect, but also less fiber attack, and also improves the tensile strength and elongation of the fiber. Rate, for cotton fabrics, there is also the effect of removing cotton pulp, improving hydrophilicity and preventing cellulose degradation.

Sterilization and disinfection of aquaculture

Silkworms are very vulnerable to pests and diseases. If the sun is not visible, the silkworms are easily deadlocked. Sodium dichloroisocyanurate is a good silkworm, silkworm and silkworm disinfectant, such as Sodium dichloroisocyanurate or Sodium dichloroisocyanurate. Spraying or smoking the disinfectant aqueous solution prepared by uniformly mixing the stabilizer and the accelerator can disinfect the silkworm, the silkworm, and the silkworm, and can prevent the silkworm disease. It not only has a good killing effect on the disease of silkworm virus, fungal disease, bacterial disease and protozoa, but also for gastrointestinal type peptic polyhedrosis, gastrointestinal type pus virus, blood type thick disease polyhedron, etc. It has a remarkable killing effect. Compared with the commonly used silkworm disinfectant, it has a fast dissolution rate, good stability, long potency, no adverse effects on the growth and development of silkworm and silkworm. One of the best disinfectants in the industry.

3.3.2 Sterilization and disinfection of aquaculture 
Sodium dichloroisocyanurate can effectively prevent fish diseases caused by bacteria, fungi and algae, and has obvious curative effects on fish viral diseases. It can be used for various fish, shrimps, crabs, Clear ponds in fish aquaculture, disinfection of fish species, disinfection of water bodies and disinfection of fish tools.

Sodium dichloroisocyanurate can be used as an additive in household dry bleaching agents, bleaching detergents, cleaning powders, dishwashing liquids, etc., to bleach and sterilize, and to increase the function of detergents, especially for protein and juice. The cleaning effect is best.

3.5 For disinfection of household sanitary disinfection
tableware, add Sodium dichloroisocyanurate 400~800mg per 1L of water, and completely kill E. coli after soaking and disinfecting for 2min. The killing rate of Bacillus can reach 98% or more for more than 8min, and can completely kill B type within 15min. Hepatitis virus surface antigen, in addition, Sodium dichloroisocyanurate can also be used for the disinfection of fruits, eggs, deodorization of refrigerator fungicides and disinfection and deodorization of toilets.

3.6 Swimming pool water disinfection
If the water in the swimming pool is not disinfected, the bacteria will grow easily. The pool wall is covered with a layer of slippery and dirty microbial algae. The pool water emits an unpleasant smell, and the swimmers come into contact with the slippery algae. It will be annoying, polluted pool water will also cause swimmers to get infected, light skin infection, severe eyes, respiratory organs infected, if you add Sodium dichloroisocyanurate in the pool water, not only the water is blue, clear and bright, the pool wall is smooth, no The adherent, the swimmer feels comfortable, and is harmless to the human body at the use concentration, and has high sterilization efficiency, which is very beneficial for protecting the health of the people.

Disinfecting 
Sodium dichloroisocyanurate in drinking water can effectively kill various algae organisms and destroy the color and odor of pollutants such as hydrogen sulfide in water. At a concentration of 2 x 106, the killing rate for E. coli, osteitis virus, sputum disease, and hepatitis virus can reach 100%.

3.8 Industrial circulating water treatment
Many industrial sectors (such as thermal power plants, petroleum refineries, chemical plants, etc.) require a large amount of cooling water to take away the heat generated in the process, many equipment such as heat exchangers, condensers, circulation A large amount of dirt is generated in the pipeline, cooling tower, and pump system due to the rapid propagation of algae. The use of fungicides to treat cooling water is one of the most effective methods, of which Sodium dichloroisocyanurate is an important fungicide. Sodium dichloroisocyanurate is used in industrial circulating water treatment system. It is an important component of industrial cold water tower water treatment agent. It can effectively prevent the growth of algae microorganisms, does not cause corrosion to industrial equipment, and can maintain the circulating water system for a long time. Water quality.

Cleaning and disinfection in the food industry, public places

Sodium dichloroisocyanurate is used more and more in the cleaning and disinfection of food processing plants, dairy processing plants, breweries, and soft beverage plants. Equipment (tanks, pipes, containers, utensils, tools, utensils, venues) that are not only in the production process, but also in the cafes, cold drinks shops, teahouses, restaurants, cafeterias (pallets, plates) , bowls, tablecloths, hand towels, etc.) Sodium dichloroisocyanurate is also often used for cleaning and disinfection to prevent infection of the disease, eliminating pigmentation, mildew, odor, etc. caused by protein, to achieve the effect of maintaining the gloss of the utensils.
