Caustic soda (also known as harsh sodium, sodium hydroxide) is a strong alkaline high-efficiency disinfectant, which has a strong killing effect on viruses, bacteria and spores, and can also kill certain parasite eggs. 1% - 2% of the aqueous solution is used for disinfecting pens, feeding troughs, utensils, transportation vehicles, etc.; 3% - 5% of the aqueous solution is used for disinfection of the anthrax spore contaminated site. Caustic soda has a corrosive effect on metal objects. It should be rinsed with water after disinfection; it has strong corrosion and damage to skin, coat, mucous membrane and clothing. Pay attention to its own protection when using. When disinfecting livestock houses and utensils, the animals must be empty or removed, and the ground should be washed with water for half a day, and the feeding trough can be allowed to enter. The lime milk used for disinfecting lime milk is made of 1 kg to 2 kg of quicklime and 10 kg of water. The lime milk has a strong disinfecting effect, but it cannot kill the spores of the bacteria, and is used for disinfecting the ground, railings, walls, etc. of the livestock and poultry house, and also for disinfecting the feces. Lime milk should not be stored for a long time and should be used now. The powder obtained by mixing 1 kg of quicklime and 300 ml-400 ml of water can also be sprinkled on the wet ground, around the septic tank and in the sewage ditch. Sprinkling quicklime directly on dry ground has no disinfection effect.
The grass ash water is freshly dried with 10 kg to 15 kg of grass ash, 50 kg of water is added, boiled for 20 minutes - 30 minutes (mixed while boiling), used for slag, generally used for disinfection of livestock and poultry house ground. Its composition is mainly potassium hydroxide and potassium carbonate, the disinfection effect is the same as 1% - 2% caustic soda.
Formaldehyde, also known as formalin, has a strong bactericidal power and has a strong disinfecting effect on spores, molds and viruses, but is highly irritating to the skin mucosa. 2%-5% formaldehyde is used for the disinfection of the ground, utensils, walls and excrement of the barn. It can be sprayed and steamed. The volume of 1 cubic meter is 25 ml of formaldehyde plus the same amount of water, heated to volatilize into gas or added to 25 Potassium permanganate fumigation.
Bleaching powder, also known as chlorinated lime, is a widely used disinfectant and its main component is calcium hypochlorite. The bleaching powder produces highly unstable hypochlorous acid in contact with water and has a strong bactericidal effect. The disinfection effect of bleaching powder is related to the effective chlorine content. The effective chlorine content is generally 25%-36%, but the effective chlorine is easily lost. Therefore, the bleaching powder should be stored in a closed and dry container and placed in a cool and ventilated place. Under the conditions of proper storage, the monthly loss of available chlorine is about 1% to 3%. It is not suitable for disinfection when the available chlorine content is less than 16%. Bleaching powder can kill bacterial spores, viruses and fungi, and is used for disinfection of pens, feeding troughs, utensils and vehicles. It is usually sprayed with a 5%-20% suspension, sometimes with a dry powder. Drinking water disinfection Add 0.3g-1.5g bleaching powder per liter of water, not only sterilization, but also deodorization.
The bleaching powder is used at the time of use, and the chlorine content is gradually reduced when stored for a long time. Cannot be used for the disinfection of colored cotton fabrics and metal appliances. Do not put together with flammable or explosive materials. Store in a cool, dry place. The bleaching powder solution is slightly toxic, and attention should be paid to the safety of humans and animals when using concentrated solutions.
Peracetic acid is a strong oxidant, which has a good disinfecting effect and can kill bacteria, viruses, spores and fungi. 0.5% solution spray disinfection housing, feeding trough, vehicle, etc.; because the decomposition products are non-toxic, can be used for surface disinfection of fruits, vegetables and food.
This product can not be stored for a long time after dilution, it should be used now. It is corrosive to metals and has a bleaching effect on colored cotton fabrics. Its vapor is irritating, and humans and animals cannot stay inside when disinfecting the house.
