(1) Peracetic acid is a colorless and transparent liquid, easily soluble in water and organic solvents. It is weakly acidic, easily volatile, has a pungent odor, and smells of acetic acid. It is easy to explode when heated at high concentrations. There is no such danger when the concentration is below 2. The commercial product is a 20 solution. The validity period is half a year, but the diluent can only maintain its efficacy for 3 to 7 months, and is usually prepared immediately for use. This product is a strong oxidant and is a highly efficient and fast-acting disinfectant and antiseptic. It has the characteristics of fast and strong bactericidal effect and broad antibacterial spectrum. It is effective against bacteria, viruses, molds and spores. A 0.05-0.5 solution can kill spores within 1 minute, and a 0.05-0.5 solution can kill bacteria within 1 minute. This product can be used for immersion disinfection of acid-resistant plastics, glass, enamel and utensils. It can also be used for spray disinfection of duck house floors, walls, troughs and indoor air disinfection.
The concentration of commercially available peracetic acid solution is 20, and the 0.04 to 0.2 solution is used for immersion and disinfection of acid-resistant appliances. Solutions of 0.05 to 0.5 are used for spray disinfection of duck houses and surrounding environments. Note: This product should not be stored for a long time after dilution (1 solution can only maintain its efficacy for a few days). This product is irritating and corrosive to tissues and corrosive to metals. Therefore, you should pay attention to self-protection during disinfection to avoid irritating the eye and nasal mucosa. (2) Bleaching powder (chlorine-containing lime)
This product is white powder, contains 25 to 30% of available chlorine, has a chlorine smell, has strong disinfection and sterilization capabilities, and can kill bacteria, germs and spores , the bactericidal effect is strong in acidic environments, but weakened in alkaline environments. Add 5 to 10 grams of bleaching powder per cubic meter of water to disinfect drinking water, which should be ready for drinking every 30 minutes. Use 1 to 3 freshly prepared solutions to disinfect non-metallic utensils (such as tableware, feeding troughs, drinking fountains, etc.). Disinfect duck houses, manure tanks, vehicles and excreta with 10 to 20% freshly prepared solution. This product should be prepared and used immediately. It is mildly corrosive to metals and clothing and irritating to tissues (skin and mucous membranes). Disinfection personnel should pay attention to protection. (3) New benzalkonium bromide (benzylamine bromide) solution This product is commercially available in three solutions: 1, 5, and 10. When diluted with water for immediate use, it is a commonly used cationic surfactant that has both sterilization and cleaning and decontamination functions. It has a wide antibacterial range, strong and fast bactericidal power, and can kill most Gram-positive bacteria and Gram-negative bacteria. However, it is less effective against viruses and cannot kill Mycobacterium tuberculosis and mold. It also has degreasing, decontamination, etc. Function, helps disinfect skin and instruments. 0.1 solution is commonly used to disinfect hands (soak for 5 minutes), eggshells, skin, surgical instruments, and glass, enamel and other utensils (soak for more than 30 minutes). The 0.01 to 0.05 solution is used for flushing and disinfecting traumatic mucous membranes (cloaca and fallopian tube prolapse) and infected wounds. An aqueous solution of 0.15 to 0.2 is used for spray disinfection of the duck house space. This product should not be used in conjunction with anionic surfactants such as soap, washing powder, peroxide, iodine, potassium iodide, etc. During immersion disinfection, the liquid must be replaced once it becomes cloudy.
