Chemical disinfection of catering establishments should be equipped with disinfectants containing chlorine. Chlorine-containing disinfectants refer to disinfectants that are dissolved in water to produce hypochlorous acid with microbial killing activity, and their microbial active ingredients are often expressed as effective chlorine. Hypochlorous acid has a small molecular weight and easily diffuses to the surface of bacteria and penetrates cell membranes.

It enters the body of the bacterium and oxidizes the bacterial protein, resulting in the death of the bacteria. Chlorine-based disinfectants kill a variety of microorganisms, including bacterial propagules, viruses, fungi, and Mycobacterium tuberculosis.

and the most resistant bacterial spores.

Precautions for commonly used disinfectants or acres and chemical disinfection in catering services:

1.Bleaching powder: The main ingredient is sodium hypochlorite.

It also contains calcium hydroxide.

Calcium oxide, calcium chloride.

Wait. When preparing the aqueous solution, a small amount of water should be added first, adjusted into a paste, and then stirred into an emulsion while adding water, and let it settle still.

2.Calcium hypochlorite (bleaching powder): fully dissolved in water when used, ordinary tablets should be crushed and added to water to fully stir and dissolve, effervescent tablets can be directly added to dissolve. The range of use is the same as that of bleaching powder.

3.Sodium hypochlorite: Mix well in water when using. The range of use is the same as that of bleaching powder.

4.Sodium dichloroisocyanurate (euchlorinate): fully dissolved in water when used, ordinary tablets should be crushed and added to water to fully stir and dissolve, effervescent tablets can be directly added to dissolve. The range of use is the same as that of bleaching powder. Shirt cheats.

5.Chlorine dioxide.

Because the prepared aqueous solution is unstable, it should be prepared and used with activator before use. The range of use is the same as that of bleaching powder. Due to the strong oxidation effect, contact with grease should be avoided to prevent accelerating its oxidation.

When using chemical disinfection and disinfection tableware, how often should the prepared disinfectant be replaced?

Common cleaning and disinfection supplies in daily life or in life: slow completion.

a.Iodine tincture. b.Alcohol;

c.Soapy water.

d.New Gil extinguished.

e.Ultraviolet lamp.

Correct answer: Shirt with ABCE

Commonly used disinfectants do not include methanol.

Commonly used disinfectants: oxidants such as hydrogen peroxide, peracetic acid, potassium permanganate, carbolic acid, lysus, hexachlorophenol and other phenols, alkylating agents such as ethylene oxide, beta-propionolactinate, propylene oxide, methyl bromide, surfactants such as Xinjieer, disinfectant, and Dufene, alcohols, aldehydes, halogens and their compounds, heavy metal salts, dyes, and acids and alkalis.

Methanol applications

1. One of the basic organic raw materials. It is mainly used in the manufacture of formaldehyde, acetic acid, chloromethane, methylamine and dimethyl sulfate and other organic products.

2. Used as a solvent for coatings, varnishes, shellac, inks, adhesives, dyes, alkaloids, cellulose acetate, nitrocellulose, ethyl cellulose, polyvinyl butyral, etc.

3. It is a raw material for the manufacture of pesticides, medicines, plastics, synthetic fibers and organic chemical products such as formaldehyde, methylamine, methyl chloride, dimethyl sulfate, etc. Others are used as automotive antifreeze, metal surface cleaning agent and alcohol denaturant, etc.

4. It is an important fuel, which can be mixed with gasoline as an alternative fuel. Since the 80s of the 20th century, methanol has been used in the production of gasoline octane additives methyl tert-butyl ether, methanol gasoline, methanol fuel, and methanol protein and other products, which has greatly promoted the development of methanol production and market needs; Methanol is already used as a fuel additive in Formula 1 cars and is also widely used in methanol fuel cells.

5. Used as analytical reagents, such as solvents, methylation reagents, and chromatographic analysis reagents. It is also used in organic synthesis.
