Hydrogen peroxide disinfectant

Hydrogen peroxide may be familiar to many friends, because it often appears in high school classrooms. Everyone's understanding of it may be limited to its chemical formula, but its role is not fully understood. The main function of hydrogen peroxide is disinfection, and different concentrations have different disinfection effects, so friends should be careful when using it.

The role of hydrogen peroxide

The main ingredient of hydrogen peroxide disinfectant is hydrogen peroxide, which is used to disinfect the surfaces of fruits, vegetables and other objects. It has a good disinfecting effect and can effectively eliminate pyogenic cocci. When soaking clothes, place them in a container filled with disinfectant, cover the lid tightly, and soak for about 30 minutes; if you are washing large items that cannot be soaked, use the wiping method to disinfect.

Bactericidal effect of hydrogen peroxide disinfectant

process

When it comes into contact with wounds, pus or dirt on the skin, mouth and mucous membranes, it immediately decomposes to produce oxygen. This oxygen atom that has not yet combined into an oxygen molecule has a strong oxidizing ability. When it comes into contact with bacteria, it can destroy the bacterial cell and kill the bacteria.

The remaining substance after killing the bacteria is water that is non-toxic and non-irritating. No secondary pollution will be caused. Therefore, hydrogen peroxide is an ideal disinfectant for wound disinfection. However, do not use highly concentrated hydrogen peroxide to disinfect wounds to prevent burns to the skin and affected area.

application

In addition, 2% to 3% hydrogen peroxide is often used as a flushing drug in oral medicine. For example, in root canal therapy in oral medicine, hydrogen peroxide is often used alternately with normal saline (0.9% sodium chloride solution) when enlarging the root canal. At the same time, hydrogen peroxide is also one of the essential drugs for pericoronal flushing. Since most infections in the oral cavity come from anaerobic bacteria, hydrogen peroxide is widely used in oral clinical medicine due to its oxygen-producing effect.

How to use hydrogen peroxide disinfectant

1. Sterilization and disinfection process of dairy production pipelines; acid, alkali, cleaning agent cleaning -> water flushing -> disinfection with disinfectant solution -> sterilization -> disinfectant recovery and sealing production;

2. Fresh milk preservation: dilute the disinfectant with water [pure water] 5-10 times at a ratio of 1:3000-5000, and then add it to the fresh milk. Add it over 5 minutes [add slowly] to extend the freshness of the fresh milk by about 3 days. C: Sterilization of milk containers;

3. Sterilization of milk containers: 1. Prepare a disinfectant liquid with a concentration of 0.5-1% with water, put the container to be disinfected into the disinfectant liquid, and soak it for 30 minutes to complete the sterilization process. 2. Disinfection of milking equipment: Prepare a 1% concentration of disinfectant liquid and soak the milking equipment in the disinfectant for more than 30 minutes. Take it out and use it when needed. Excellent disinfection effect, can make milking equipment work in a clean and odorless state;

4. Disinfection and sterilization of cow's udder: prepare 1%-2% concentration of disinfectant liquid, and rinse, spray or smear on the cow's udder. Disinfection effect can be achieved in 2 minutes;

5. Disinfection of equipment surfaces in the production workshop [space]; (1): Use tap water to prepare a 1% concentration of disinfectant liquid, and spray it on the production workshop space for disinfection. Since the disinfectant is non-toxic and odorless, it can be sprayed while workers are working on site: (2): Disinfection of equipment surfaces: Use a sprayer to spray the prepared disinfectant liquid [concentration 2%] on the equipment surface for about 2 minutes. [0,5 concentration, spraying time 10 minutes]

6. Preparation of sterile water: Add the stock solution [36%] into water at a ratio of 1:3000, stir evenly, and sterile water can be made in about 100 minutes. Note: The higher the concentration, the shorter the time; otherwise, the longer the time. Preparation and use (disinfection of beer dispensing equipment)
