What are the disinfectants for disinfecting tableware?

Disinfectant is needed for disinfection of tableware. Which ones are usually used? Is the disinfection effect the same. Next, let's get to know it together. 1. 10% Edible caustic soda water for lye disinfectant (Warm water) Soaking and disinfecting tableware not only has a good effect of removing oil stains, but also has a certain disinfection effect. 2, chlorine-containing disinfectants, commonly used are: ① bleaching powder: white alkaline granular powder, chlorine odor, containing effective chlorine 25 ~ 30% (Generally calculated at 25%). Unstable nature, light, heat, moisture, exposure, etc. can accelerate the decomposition, volatilization, failure, corrosive. (2) sodium hypochlorite: light yellow clear and transparent liquid, generally containing 10% effective chlorine. ③ Calcium hypochlorite (Bleach powder) : White powder with chlorine odor is more stable than bleaching powder. Containing available chlorine 60 ~ 65%, with strong corrosion and bleaching effect. The chloramine t (Chloramine) : White yellowish crystalline powder, containing available chlorine 24 ~ 26%, the nature is relatively stable and easy to store. 3, peroxide disinfectant. The principle of disinfection is to make the enzyme on the disinfection tableware lose its activity according to its oxidation, resulting in the death of microorganisms. It is characterized by wide sterilization spectrum, strong sterilization, fast decomposition, no residual poison, simple and convenient use and configuration, etc. It should be noted that peroxide disinfectants, like chlorine-containing disinfectants, have bleaching and corrosion effects on silk articles. (1) peracetic acid peracetic acid commercially available (Peracetic acid) The concentration is mostly about 20%, and the commonly used disinfection concentration is 0. 2 ~ 1%. Disinfection method: Soak, wipe, spray or spray with its solution. The prepared dilute solution is at normal temperature (15 ~ 25 ° C) The storage time should not exceed 2 days and 4℃ should not exceed 10 days. ② Chlorine dioxide (Chlorine peroxide) Chlorine dioxide is internationally recognized as a new generation of safe, efficient, broad-spectrum sterilization, preservation and removal of Austria, and is an ideal substitute for chlorine preparations, it has been widely used in disinfection, deodorization, mildew prevention and food preservation in food, food processing industry, pharmaceutical industry, hospital and public environment in developed countries. Its disinfection mechanism: chlorine dioxide releases free chlorine dioxide through activation, and chlorine dioxide unstably releases new ecological atomic oxygen; Cl02 → C1-2 [O] The atomic oxygen of the new ecology has a strong oxidation effect. By oxidizing the active groups of the protoplasmic protein of the microorganism, the amino acids in the protein are oxidized and decomposed to achieve the purpose of killing germs and viruses. Its bactericidal ability is chlorine 2. 5 times. Chlorine dioxide can also interact with ammonia, sulfide and organic matter in the air or on the surface of various substances, thus achieving the effect of removing odor. 4, quaternary ammonium salt disinfectant. Commonly used are new gerbil, meifan, etc. The common concentration is 0. 1 ~ 0. 5%, the use method is mainly soaking, wiping, spraying, etc. Mainly used for hand disinfection. The mechanism of action is mainly to change cell permeability and rupture of thallus. It is characterized by low concentration, colorless solution, no pollution, no corrosion and bleaching effect, stable properties, heat resistance, light resistance, long shelf life, low toxicity, strong surface activity, convenient use, etc. The disadvantage is that the killing effect on some microorganisms is not good, especially on bacterial spores. In addition, the price is more expensive, the preparation of more taboos, affected by organic matter. 5, alcohol disinfectant. The sterilization mechanism is to make protein denaturation, antibacterial reproduction and bacteria. It is characterized by stable nature, fast action and no corrosiveness. It can be used in conjunction with other disinfectants to enhance sterilization. The most commonly used is 75% ethanol solution, which can kill bacterial propagules and Mycobacterium tuberculosis in 5 minutes. From the above content, we can easily see that the role of each disinfection tableware disinfectant is different, so we generally choose to determine according to the actual situation.
