English name: Sodium dichloro-isocyanurate
Sodium Dichloroisocyanurate is an important variety of chlorinated isocyanuric ACID products. It is a broad-spectrum, high-efficiency and low-toxicity disinfectant with a wide range of uses. It is also an ideal upgrading product for traditional disinfection products such as sodium hypochlorite, bleaching powder and bleaching powder essence.
Sodium dichloroisocyanurate is mainly used for:
Wool shrink-proof treatment agent
Using 2% - 3% sodium dichloroisocyanurate solution and adding other additives to impregnate wool or wool blended fibers and fabrics can make wool and its products not pilling and felting.
Bleaching in textile industry
In the textile industry, sodium dichloroisocyanurate is mainly used as a bleaching agent for natural fibers and synthetic fibers. Compared with traditional bleaching agents, sodium dichloroisocyanurate has many unique advantages. For example, general bleaching agents are required to be used at higher temperatures. High temperatures will intensify the erosion of bleaching agents on fibers and reduce fiber strength, while sodium dichloroisocyanurate can still achieve good bleaching effect even at lower temperatures. In addition, sodium dichloroisocyanurate is used to bleach natural and synthetic fibers, which not only has good effect, but also can improve the tensile strength and elongation of fibers.
Sterilization and disinfection of aquaculture
Sodium dichloroisocyanurate is a good disinfectant for the silkworm room, silkworm tools and silkworm body. If sodium dichloroisocyanurate or sodium dichloroisocyanurate is used as the main body, and the disinfectant water solution mixed with stabilizer and accelerator is sprayed or smoked, it can disinfect the silkworm room, silkworm tools and silkworm body, and can prevent and cure silkworm disease. At the same time, sodium dichloroisocyanurate can effectively prevent and cure fish diseases caused by bacteria, fungi and algae, and has obvious curative effect on fish viral diseases. It can be used for pond cleaning and disinfection, water body disinfection and fish gear disinfection of various fish, shrimp, river crab, bullfrog and other aquaculture.
Detergent additive
Sodium dichloroisocyanurate can be used as an additive for household dry bleach, bleach detergent, cleaning powder, tableware detergent and other washing products, playing a bleaching and sterilization role, improving the function of detergent, especially for protein and fruit juice.
Civil sanitary disinfection
When tableware is disinfected, 400-800 mg of sodium dichloroisocyanurate is added to each liter of water. Immersion and disinfection for 2 minutes can completely kill Escherichia coli, the killing rate of Bacillus can reach more than 98% for more than 8 minutes, and hepatitis B virus profile antigen can be completely killed in 15 minutes. In addition, sodium dichloroisocyanurate can also be used to disinfect the appearance of fruits and eggs, disinfect and deodorize refrigerators, and disinfect and deodorize toilets.
Disinfection of swimming pool water
Add sodium dichloroisocyanurate into the swimming pool water, not only the water is blue, clear and shiny, the pool wall is smooth, and there is no adhesion, so swimmers feel comfortable, but also it is harmless to human body at the correct concentration, with high sterilization efficiency, and is very beneficial to protect human health.
Adjust the dosage according to the size and water quality of the swimming pool. Add 2-3 grams per cubic meter of water (2-3 kilograms per 1000 cubic meters of water)
Drinking water disinfection
Sodium dichloroisocyanurate used in drinking water can effectively kill all kinds of algae and destroy the color and smell of hydrogen sulfide and other pollutants in water. At a certain concentration, the killing rate of Escherichia coli, dysentery and hepatitis virus can reach 100%.
Industrial circulating Water Treatment
A large amount of cooling water is needed in the industrial field. Many cooling water equipment will have a large amount of dirt due to the rapid growth of algae, which will affect the use of cooling water. It is a very effective way to solve this problem by using fungicides to treat cooling water. Sodium dichloroisocyanurate is used in the industrial circulating water treatment system, which can effectively prevent the growth of algae microorganisms and will not cause corrosion to industrial equipment.
When euchlor is used as biocide in the circulating cooling water system, 15-20ppm is added every 2-3 days in summer, every 3-5 days in spring and autumn, and every 5-7 days in winter. To ensure the killing effect, non-oxidizing bactericide can also be added regularly.
Cleaning and disinfection of food enterprises and public places
Sodium dichloroisocyanurate is used more and more widely in the cleaning and disinfection of the food industry. Not only the equipment in the production process should be cleaned and disinfected, but also the utensils in cafes, cold drinks shops, tea houses, restaurants and other places should also be cleaned and disinfected with sodium dichloroisocyanurate to prevent disease infection and eliminate stains, mildew, and odor caused by protein.
In the above fields, sodium dichloroisocyanurate is often used in combination with phosphate, silicate, general active agent and neutral salt to enhance its efficacy.
