(6) The product is solid and can be made into white powder or granules for easy packaging and transportation, making it convenient for users to choose and use.

SDIC is an efficient disinfectant with high solubility in water and long-lasting disinfection ability, with lower toxicity, so it is widely used as a drinking water disinfectant and household disinfectant. SDIC can hydrolyze into hypochlorous acid in water, so it can replace hypochlorous acid in some cases and be used as a bleaching agent. Because SDIC can be mass-produced on an industrial scale and is relatively cheap, it is widely used in many industries:

[Wool shrinkage prevention agent]
SDIC can release uniform amounts of hypochlorous acid in water solutions, which react with the protein molecules in the wool scale layer to break some of the bonds in the protein molecules, causing changes in the molecular structure to prevent wool shrinkage. In addition, SDIC can be added to laundry detergent and other cleaning agents to prevent wool from sticking and forming balls during washing. Wool fabrics treated with SDIC have bright colors and good texture, and shrinkage is minimal; by adding 2-3% SDIC solution to wool or wool blend fibers and fabrics, the occurrence of pilling and shrinkage can be effectively prevented.

[Textile industry bleaching]
SDIC is also widely used as a bleaching agent for natural fibers and synthetic fibers in the textile industry. The bleaching principle is to destroy the pigments in natural fibers and synthetic fibers. SDIC can release hypochlorous acid evenly in water solution, which can change some chromophore groups in fibers by adding conjugated bonds through addition reaction with the altered fibers. This destroys the original color of the fibers and changes the wavelength of light absorption, thus achieving the purpose of bleaching. Compared with traditional bleaching agents, SDIC has great advantages. Traditional bleaching agents can only be used at low temperatures because the speed of destroying the molecular structure of fibers by traditional bleaching agents will accelerate at high temperatures, and the strength of fibers will be greatly affected. However, SDIC can still achieve good bleaching effects at lower temperatures. In addition, the destruction speed of SDIC to the molecular structure of natural fibers and synthetic fibers is slower, the bleaching effect is good, and the strength of fibers will not be affected too much. In addition, adding SDIC to bleaching agents can also improve the hydrophilicity of clothes, remove cotton slurry from clothes, reduce the degradation speed of cellulose, and improve the flexibility and extensibility of clothes. Using SDIC as the main ingredient, adding an appropriate amount of stabilizers and promoters, and mixing the three evenly to form a disinfectant water solution, can disinfect and kill bacteria and fungi on the silkworm body and in the living environment. It can quickly kill viruses, fungi, and bacteria that affect silkworms. SDIC water solution can be sprayed on silkworm cages, silkworm tools, and the silkworm body to prevent silkworm diseases and kill gastrointestinal pycnidial bodies of gastrointestinal pycnidial virus and hemorrhagic pycnidial virus. Compared with traditional silkworm disinfectants, SDIC-based disinfectants have higher solubility, greater stability, and longer-lasting effects. As an excellent disinfectant for the silkworm industry, SDIC has little effect on the growth and development of silkworms and the quality of silk.
(2) Disinfection and sterilization in aquaculture SDIC also has excellent performance in preventing fish diseases. It can quickly kill bacteria and fungi in water and can also prevent viral diseases in fish. Therefore, SDIC is often used for water disinfection in aquaculture of fish, shrimp, crabs, and frogs. It is also used for disinfection of fish cages and fishing tools. The disinfection effect of SDIC on drinking water: After drinking water is disinfected, the survival rate of chickens is around 97%, while the average survival rate of chickens that have not been disinfected is 90.07%. This is a difference of nearly 7 percentage points. Disinfecting the water with sodium dichloroisocyanurate (SDIC) is beneficial to the health of the chicken flock and greatly improves the survival rate of chickens. Naturally, it improves economic efficiency.

【Domestic hygiene disinfection】
(1) SDIC as a surfactant additive in household tableware detergent etc. Adding an appropriate amount of SDIC to household tableware detergent and other household cleaning products can enhance the function of the detergent and make it capable of killing bacteria and viruses. It has a particularly significant effect on cleaning stains containing protein and juice. 600mg of SDIC can be added to 1L of water. After soaking the tableware in the water for 2 minutes, 100% of E. coli can be killed. After soaking for 8 minutes, the survival rate of Bacillus spores is reduced to only 2%. After soaking for 15 minutes, the hepatitis B virus will be completely killed. In addition, SDIC is widely used in the disinfection of agricultural products such as fruits, vegetables, and eggs. It is also a common additive for refrigerator disinfectant and toilet deodorant.
(2) Water disinfection in swimming pools
Water in swimming pools is very suitable for the reproduction of bacteria and other microorganisms. If it is not regularly disinfected, algae and other microorganisms will rapidly multiply, causing the pool water to emit a nauseating odor and form a slippery and dirty sludge that adheres to the pool wall. When swimmers encounter these impurities while swimming, they will feel disgusted, and they can also infect the swimmer's skin, even the swimmer's eyes, respiratory tract, and respiratory organs. SDIC disinfectant tablets can be added to the swimming pool water in appropriate amounts, not only to keep the water clear and bright, but also to keep the pool wall clean, remove adhesive substances, and make swimmers feel happy. Under the use concentration, the SDIC disinfectant tablets have good bactericidal effect and are basically harmless to human body.
(3) Drinking water disinfection
Adding appropriate amount of SDIC to drinking water can quickly kill various bacteria, viruses and other microorganisms. Not only that, SDIC can also destroy the molecules of pollutants such as hydrogen sulfide in water, eliminating their color and odor. The killing effect of SDIC on enterovirus and E. coli is significant. When 10mg of SDIC is added to 1 liter of water, the survival rate of E. coli in the water is 0.01%.

[Industrial circulating water treatment]
Many thermal power plants, oil refineries, and chemical factories produce a lot of heat in the production process. These heat needs to be treated by a large amount of cooling water. Generally, these industrial enterprises adopt heat exchangers such as heat exchangers, condensers, circulating pipelines, cooling towers, and pump systems for heat treatment. However, algae are very easy to breed in these heat exchangers, thereby producing a lot of scale. The use of disinfectants can effectively control algae in cooling water, and SDIC is a commonly used cooling water disinfectant. SDIC can efficiently inhibit the reproduction of algae microorganisms in cooling water and has a minimal impact on the corrosion of industrial equipment. It can maintain the quality of the circulating water system in a good state for a longer period of time. Therefore, SDIC is an important component of industrial cooling water treatment agents.

【Food Industry, Cleaning and Disinfection in Public Places】
The food processing industry, such as dairy processing plants and breweries, has also begun to use SDIC in large quantities for cleaning and disinfection. It is mainly used for disinfection and sterilization of processing equipment during production processes, such as containers, pipes, tools, and production equipment. Some catering industries such as cold drink shops, tea houses, and restaurants also often use SDIC to disinfect tableware such as plates, bowls, tablecloths, and handkerchiefs. Using SDIC can keep tableware and food processing equipment clean and eliminate protein-induced stains, mold stains, unpleasant odors, and maintain the luster of tableware, preventing the spread of diseases.
