Recently, I have been reading about several domestic brand schools and kindergartens for my child. The most talked about materials are teaching methods and service concepts, but I have hardly seen any content related to food safety and environmental safety. Food safety and environmental safety directly affect children's health, and the overall environment is worrying. Why can't efforts be made in this regard. If we can create unique features that are not easily imitated in the small environment of kindergarten, this is the most direct way to express love, which may become a highlight of early childhood education, improve parents' satisfaction and dependence, and enhance the social responsibility and reputation of enterprises.

A new product has been developed according to the standards of the Ministry of Health, which can turn ordinary water into disinfectant and comprehensively solve the disinfection and sterilization problems in multiple aspects of kindergartens, including fruits, vegetables, fish and other foods, kitchen equipment and utensils, children's and staff's skin, various toys (including plush toys), silk fabrics, floors, walls, vehicles, etc. It is pollution-free, non-toxic, safe and reliable, with low cost of use and practical methods. About 100000 yuan, better than UV, ozone, and 84 disinfectant.

The following are some points summarized based on relevant paper reports for reference:

(1) Hand washing or overall body disinfection: You can use disinfectant like tap water, rinse or spray for 5 seconds to kill bacteria and viruses on the body surface, and soak your feet in acid water for 5-10 minutes.

(2) Cleaning and disinfection of food, fruits, and vegetables: Use alkaline water to clean the surface of dirt. For those with high pesticide residues, soak them for 10-20 minutes to remove pesticide residues. Soak them in acidic water for 3-5 minutes for disinfection, and they can be eaten raw. For meat and fish, soaking them in acidic water for 1 minute in a freezer can extend their shelf life by more than twice. Soak them in alkaline water for 20 minutes before consumption to remove blood stains and odors.

(3) Cleaning and disinfection of toys, tableware, and stoves: Use acidic water to scrub and soak for 3-5 minutes. For those with oil stains, use alkaline water to clean them first, and then store them in a sterile storage cabinet for natural air drying and preservation.

(4) Cleaning and disinfecting the surface of items; Cleaning and disinfecting items such as headboards, tables and chairs, countertops, cabinets, large naughty castles, sinks, toilets, slippers, washbasins, stair handrails, etc. Wipe and rinse the surface of items with acidic water for about 10 seconds to kill pathogenic microorganisms.

(5) Fabric cleaning and disinfection (including plush toys): Soak in alkaline water for 10 minutes in a washing machine (such as fabric dye proteins, blood stains, and juice pigments, which should be treated with a small amount of active enzymes), then wash and spin dry. Rinse with a small amount of acidic water for 3-5 minutes and spin dry to save water, clean, disinfect, and kill bacteria.

(6) Cleaning and disinfection of indoor space, floor, wall, outdoor large toys and vehicles: put the acid oxidizing potential water into the spray and spray it directly in the room, corridor and hall, so as not to hinder the normal activities of indoor personnel. Wipe and disinfect ceramic floors, walls, and floors with acidic water.

Attachment: Introduction to Strong Acid Water

The bactericidal efficiency of strong acid water: It can kill pathogenic bacteria such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, avian influenza virus, Bacillus subtilis var. niger spores, Neisseria gonorrhoeae, fungi, and molds. And the sterilization speed is extremely fast. In the absence of organic matter, it can kill 100% of bacterial colonies in 15 seconds; Acting for 30 seconds can destroy the surface antigenicity of hepatitis B virus; After 10 minutes of action, it can kill the spores of Bacillus subtilis var. niger.

The disinfection and sterilization principle of strong acid water: Ordinary water forms an electrolyte solution with high conductivity by adding 0.05% sodium chloride (salt). Under the action of the electrode, it is decomposed into OH ions and H ions. These ions react with the chloride ions and sodium ions in the aqueous solution containing sodium chloride to form hypochlorous acid and sodium hydroxide. This process can only be achieved under the action of a cation exchange membrane, so that the hypochlorous acid ions formed by the chemical reaction are enriched in the anode, while the hydroxide ions are enriched in the cathode. In this way, strong oxidation (ORP of+900--+1200mv) hypochlorous acid water with high potential is formed in two tanks. The pH value of this water is usually below 2.7, which is similar to high oxidation (ORP of+900--+1200mv) hypochlorous acid water. A strong alkaline hydroxide solution with a reducing potential of ORP-800 mv, typically with a pH value of 10-13 or higher.

The chemical characteristic is that water electrolysis forms hypochlorous acid, which further decomposes to form new ecological oxygen [O]. The extremely strong oxidizing nature of new ecological oxygen causes denaturation of proteins and other substances on bacterial cells and viruses, thereby killing pathogenic microorganisms. According to chemical measurements, PPM level concentrations are almost completely electrolyzed into hypochlorous acid in water, with an efficiency higher than 99.99%. The process can be simply represented by chemical equations as follows:

NaClO+H2O=HClO+NaOH

HClO → HCl+[O]

Secondly, in the process of sterilization and virus killing, hypochlorous acid can not only act on the cell wall and virus shell, but also penetrate into the body of bacteria (viruses) due to its small size and lack of charge, and undergo oxidation reactions with organic macromolecules such as bacterial (virus) proteins, nucleic acids, and enzymes, thereby killing pathogenic microorganisms.

R-NH-R+HClO → R2NCl+H2O

At the same time, the chloride ions produced by hypochlorous acid can significantly alter the osmotic pressure of bacteria and viral bodies, causing their cells to lose activity and die. In addition, it can decompose trace pesticides remaining on agricultural and sideline products such as vegetables and fruits. The vast majority of pesticides are composed of organic matter, and the newly released oxygen can oxidize and decompose these substances. Disinfected fruits and vegetables can be consumed directly without cleaning.

It is also worth acknowledging that the disinfectant produced does not produce free chlorine in water like chlorine gas, chlorine dioxide and other disinfectants, so it is generally difficult to form carcinogens that are harmful to human health due to the presence of free chlorine; It is not like ozone, where even a small amount (0.001mg/m3) in the air can cause damage and toxicity to life; Moreover, it will not cause severe corrosion to metal pipelines like chlorine reacts with water to form hydrochloric acid. The disinfection and oxidation capabilities far exceed chlorine gas, and it does not generate harmful organic halides and trihalomethanes (carcinogens) like chlorine gas does. Can effectively destroy harmful substances such as phenols, sulfides, cyanides, etc.

The physical property is that an aqueous solution containing hypochlorous acid has a high oxidation potential. Once it comes into contact with bacteria, fungi, or viruses, it forcibly acquires electrons from the biological membrane, changing the normal potential and permeability of the cell membrane, causing the oxidative permeability of the lipid membrane to be destroyed. It is like drilling a hole in the cell membrane, leading to the leakage of cell contents and death. This process belongs to a physical process and can achieve good results within 1-10 minutes. Therefore, it is faster and more thorough than chemical sterilization in application, and will not cause any resistance of bacteria.
