The types of industrial fungicides mainly include tetravalent ammonium series, phenols, chlorine and bromine oxides, halogenated, organometallic, organic sulfur and heterocyclic compounds. Trichloroisocyanuric acid industrial bactericide is widely used in ordinary production and life.
1. Tetravalent ammonium Bactericides
Tetravalent ammonium series mainly include: phenyltrimethylammonium chloride, dialkyldimethylammonium chloride, cetyltrimethylammonium bromide, cetyl arsenic hydrochloride, etc. They have become an unusual wide range of commercial products. Trichloroisocyanic acid and other industrial bactericides learned that haloalkanes can be short chain, long chain or phenyl, and different groups can be selected according to needs. Tetravalent ammonium has limited industrial applications, mainly used in medicine and public health. Therefore, in these aspects, the activity of bactericides can only kill delicate bacteria. Secondly, it is also used in swimming pools and cooling water systems as an algicide. Its mechanism of activity has been widely studied. The basic view is that tetravalent ammonium interacts with cell membrane to kill bacteria.
2. Phenol fungicide
O-phenyl p-chlorophenol, pentachlorophenol and 2,4,4-trichloro-2-phenoxyphenol, etc. Phenol is used for wood protection. Sodium phenylphenol is still an important component in cooling water treatment, and can also be used for caulking, building materials and leather protection. Similarly, p-chloro-m-xylenol is used for the protection of some water-based items, including the mold resistance of ink, emulsion, shoe polish and leather. 2,4,4-trichloro-2-phenoxyphenol can be used in personal cleaning products, cosmetics and soaps to kill bacteria.
3. Chlorine and bromine oxides and halogenated alkyl fungicides
Chlorine and bromine oxides include chlorine, nitrogen dioxide, hypochlorous acid, sodium hypochlorite, hypobromic acid, etc. The activity of chlorine gas is particularly dominated by the pH value of the solution. It shows very high activity when the pH value is less than 7, because the active bactericide sodium hypochlorite is not decomposed. Organic chlorine compounds can prevent the destruction of photolysis and improve the stability in swimming pools. Organic chlorine should also be treated with cooling water. Industrial fungicides such as trichloroisocyanic acid have learned that bromochlorodimethyl hydantoin can be rapidly hydrolyzed in water to generate hypobromic acid, with a pK of 8.8 for hypobromic acid and 7.4 for hypochlorous acid. Since the undissociated hypohalic acid is an active bactericide, the generated hypobromic acid is more active in alkaline systems. Chlorine dioxide is not as important as it used to be because of its volume; And the new technology has enabled potassium chlorate to produce chlorine dioxide. Halogenated alkyl fungicides mainly include trichloroisocyanic acid, dichlorodimethyl hydantoin, benzyl bromoacetate, etc. It is mainly used as disinfectant for swimming pool and general disinfectant, and can be used for paint, latex, recycled oil recovery, metal processing fluid and wood antibacterial agent.
Trichloroisocyanuric acid, also known as TCCA, is a white crystalline powder or granular solid with a strong chlorine irritating taste. Trichloroisocyanic acid industrial bactericide is a very strong oxidant and chlorination agent, with high efficiency, broad spectrum and relatively safe disinfection effect. It can kill bacteria, viruses, fungi, spores, etc., as well as coccidial oocysts. It is a new generation of broad-spectrum, high-efficiency and low toxicity fungicides, bleaches and anti shrinking agents. It is mainly used for disinfection and sterilization of drinking water, industrial circulating water, swimming pools, restaurants, hotels, public places, families, hospitals, poultry eggs and prevention of fish lesions.
4. Organometallic, organosulfur and heterocyclic fungicides
Organometallic fungicides mainly include organic mercury, tin, steel, arsenic and sulfur compounds. Such as phenylmercury acetate, 102102 - oxodiphenoxapyr (OBPA), tributyltin oxide, copper naphthenate, etc. Mercury compounds have broad-spectrum bactericidal activity and efficacy advantages, but due to the harm of mercury. Trichloroisocyanic acid Industrial Bactericide learned that it was eliminated first. OBPA is widely used as a mold inhibitor in plastics due to its thermal stability, low vapor and broad-spectrum activity. Organotin is mainly used in anti fouling paints. Latex paint and plastic; Organic copper is mainly used in textiles and wood; organic sulfur is mainly used in cooling water, paint, metalworking fluid, plastic and recycled oil recovery. Heterocyclic compounds except bactericides of clothing industry; It is mainly used in paint, cosmetics, leather and metal processing fluid in the industrial field.
5. Industrial amines, alkyl amines and nitro containing bactericides and hybrid Bactericides
Industrial amines, alkyl amines and nitro containing bactericides are mainly used in metalworking fluids and cosmetics. Mixed fungicides are mainly used in latex paint, textiles and floor wax.
