DCCNa is a highly efficient disinfectant with high solubility in water, long-lasting anti-virus ability and low toxicity, so it is widely used as drinking water disinfectant and household disinfectant. DCCNa can hydrolyze hypochlorous acid in water, and can replace hypochlorous acid in some cases, so it can be used as bleach. And because DCCNa can be large-scale industrial production, the price is low, so it is widely used in many industries:
Wool shrinkage treatment agent
DCCNa can release hypochlorous acid uniformly in aqueous solution, interact with protein molecules in the wool scale layer, break some bonds in the protein molecules, and change the molecular structure to prevent wool shrinkage. In addition, DCCNa can also be added to laundry detergent and other detergents, so that it can effectively prevent the occurrence of wool bonding and pilling when washing wool products. The wool fabric treated by DCCNa has bright color, good hand feel, and basically will not shrink. Adding 2%~3% DCCNa solution to wool or wool blend fiber and fabric leaching additives can effectively prevent wool and its products from pilling, felting and other phenomena.
Textile bleaching
DCCNa is also widely used in bleach for natural and synthetic fibers in the textile industry. Bleaching works by destroying pigments in natural and synthetic fibers. DCCNa can release hypochlorous acid uniformly in aqueous solution, and hypochlorous acid can change some color base groups in the fiber through addition reaction with its conjugated bond, destroy the original pigment in the fiber, and change the wavelength of light absorbed by the fiber, so as to achieve the purpose of bleaching. Compared with the use of traditional bleach, DCCNa has a great advantage, the traditional sense of bleach can only be used under low temperature conditions, because the speed of traditional bleach to destroy the molecular structure of the fiber will be accelerated under high temperature conditions, and the strength of the fiber will be rapidly reduced under its influence. DCCNa can still obtain good bleaching effect even at low temperature. In addition, the molecular structure destruction rate of natural fiber and synthetic fiber with DCCNa is slower, the bleaching effect is good, and the strength of fiber will not be greatly affected. In addition, adding DCCNa to bleach can also improve the hydrophilicity of clothing, remove the cotton pulp in clothing, and reduce the degradation rate of cellulose, while improving the flexibility and ductility of clothing.
Sterilization and disinfection of aquaculture
(1) Sterilization and disinfection of sericulture If there is some negligence in sericulture, bacteria and pests will cause damage to the silkworm, and even make the silkworm die. The use of DCCNa as the main component, adding an appropriate amount of stabilizer and accelerator, so that the three evenly mixed to form a disinfectant solution, the silkworm body and the living environment of the silkworm body disinfection and sterilization, can quickly kill the virus, fungus and bacteria affecting the silkworm. DCCNa aqueous solution can be sprayed on silkworm house, silkworm ware and silkworm body, which can prevent silkworm disease and kill gastrointestinal pyogenic polyhedron, gastrointestinal pyogenic virus and blood polyhedron. Compared with the traditional disinfectant for silkworm, the disinfectant with DCCNa as the main component has higher solubility, more stable and longer duration of efficacy. As an excellent disinfection drug for the development of sericulture, DCCNa has little effect on the growth and development of silkworm and silkworm quality.
(2) The sterilization and disinfection of aquaculture in the prevention of fish diseases, DCCNa also has a good performance. It can quickly kill bacteria, fungi and other microorganisms in the water body, and can also prevent and control viral diseases of fish. Therefore, DCCNa is often used for disinfection of aquaculture fish, shrimp, crabs, frogs and other aquatic products. It is also used in disinfection of fish species and disinfection of fish utensils. Sodium dichloroisocyanurate drinking water disinfection effect: after drinking water disinfection, the survival rate of chickens is about 97%, and the survival rate of chickens without disinfection of drinking water is 90.07% on average, nearly 7 percentage points more, the water disinfected by sodium dichloroisocyanurate to chickens drinking, is of great benefit to the health of chickens, greatly improve the survival rate of chickens, naturally improve the economic benefits.
Civil disinfection
(1) Detergent additives Add an appropriate amount of DCCNa to household tableware washing liquid and other washing products, which can increase the function of detergent, so that it can play the role of antivirulence and sterilization, and the effect of cleaning stains containing protein and juice is very significant. Weigh 600mgDCCNa and add it to 1L of water, put the tableware in water for 2 minutes to kill 100% E. coli, after 8 minutes of immersion and disinfection, the survival rate of Bacillus can be reduced to only 2%, and after 15 minutes of immersion and disinfection, the hepatitis B virus can be completely killed. In addition, DCCNa is also widely used in the disinfection of fruits, vegetables, poultry eggs and other agricultural products, and is a common addition to refrigerator disinfectants and toilet disinfection deodorants.
(2) Swimming pool water disinfection Swimming pool water is very suitable for bacteria and other microorganisms reproduction. If not disinfected regularly, algae and other microorganisms can quickly grow, giving the water a disgusting smell and sticking to the walls of the pool to form a slippery, dirty layer of dirt. Touching these dirt while swimming will make the swimmer feel disgusted, but also infect the swimmer's skin, and even infect the swimmer's eyes, respiratory tract and respiratory organs. The appropriate amount of DCCNa disinfection tablets can be added to the swimming pool water, which can not only keep the water clear and shiny, but also keep the pool wall clean, remove adhesion, and make the swimmer physically and mentally happy. In the use of the concentration of DCCNa disinfection tablet sterilization effect is good, basically no harm to the human body.
(3) Drinking water disinfection [1] Adding an appropriate amount of DCCNa to drinking water can quickly kill various germs, viruses and other microorganisms. Not only that, DCCNa can also destroy pollutant molecules such as hydrogen sulfide in water, eliminating its color and its odor. DCCNa has a significant killing effect on pathogenic viruses and Escherichia coli. When 10mgDCCNa is added to every liter of water, the survival rate of Escherichia coli in water is 0.01%.
Industrial circulating water treatment
Many thermal power plants, petroleum refining plants, chemical plants in the production process will produce a lot of heat. This heat requires a lot of cooling water to deal with. In general, these industries will use heat exchange equipment such as heat exchangers, condensers, circulation pipes, cooling towers, pump systems, etc. But the algae in these heat exchangers are very easy to multiply and breed a lot of dirt. The use of fungicides can be very effective treatment of algae in cooling water, among which DCCNa is a more commonly used fungicide in cooling water. DCCNa can effectively inhibit the propagation of algae microorganisms in cooling water, and the erosion of industrial equipment is small, and the water quality in the circulating water system can be kept in good condition for a long time. Therefore, DCCNa is an important part of industrial cooling water treatment agent.
Cleaning and disinfection of food industry and public places
Food processing industries such as dairy processing plants, breweries and other beverage plants have also begun to use DCCNa in large quantities for cleaning and disinfection. Mainly used in containers, pipelines, tools, sites and other processing process equipment disinfection and sterilization. There are also some catering industries such as cold drinks, tea houses, restaurants, etc., often use DCCNa to disinfect trays, bowls, tablecloths, hand towels and other tableware. The use of DCCNa can maintain the hygiene of tableware and food processing equipment and eliminate stains, mildew, odor, etc. caused by protein, maintain the luster of tableware and prevent the transmission of diseases.
