What is the principle of ozone disinfection? What is the principle of ozone sterilization?

1. Mechanism of ozone inactivation of bacteria:

The inactivation of bacteria by ozone is always rapid. Unlike other fungicides, ozone can react with the lipid double bonds of the bacterial cell wall, penetrate into the bacteria, act on proteins and lipopolysaccharides, change the permeability of the cell, and cause the death of bacteria.

Ozone also acts on nuclear substances inside the cell, such as purines and pyrimidines in nucleic acids, to destroy DNA.

2. The mechanism of ozone inactivation of viruses:

The effect of ozone on viruses is first of all the four polypeptide chains of the capsid shell protein of the virus, and causes damage to the RNA, especially the proteins that form it. After the phage is oxidized by ozone, electron microscopy can show that its epidermis is broken into many fragments, from which many ribonucleic acids are released, which interfere with its adsorption to the register. The thoroughness of ozone sterilization cannot be questioned.

Ozone, also known as triatomic oxygen, commonly known as "blessed oxygen, superoxygen, active ozone", the molecular formula is O3, ozone at room temperature and pressure, light blue gas, accompanied by a natural fresh taste, the stability of ozone is very poor, it can be decomposed into oxygen by itself at room temperature, so ozone can not be stored, generally produced on site, and used immediately. Ozone is a known broad-spectrum, efficient, rapid, safe, non-secondary pollution bactericidal gas, which can kill bacterial spores, viruses, fungi, etc., and can destroy botulinum toxin. It can kill the toxins attached to fruits, vegetables, Icelandic penicillin bacteria, black variant spores, natural bacteria, gonorrhoea, etc., and can also kill infectious viruses such as hepatitis A and B, and can also remove toxins from pesticide residues and detergent residues in fruits and vegetables.

Its bactericidal mechanism is to act on the cell membrane of bacteria to damage the cell membrane composition, resulting in metabolic disorders and inhibiting its growth until death; Its mechanism of killing viruses is done by directly destroying its ribonucleic acid or deoxyribonucleic acid. The mechanism by which pesticides are degraded is achieved by directly breaking their chemical bonds.

Ozone O3 is an allotrope of oxygen O2, which has the same constituent elements, different constituent forms, and very different properties.

Ozone is highly oxidizing, so it can cause bacterial proteins to lose their normal function.

Our factory is also sterilized with Guangzhou Huanwei's ozone machine, which used to be open for a long time when I came to work in the morning, but it smelled big Later, the ozone was used in advance, and there was no longer a smell, and the sterilization effect was good.

Ozone denatures proteins, which kills fungi.

Summary. Hello, the principle of ozone disinfection machine is: oxidation reaction, which is the inactivation of bacteria and viruses by ozone.

Ozone responds quickly to the inactivation of bacteria. Ozone can penetrate into the bacterial body by reacting with the lipid double bond of the bacterial cell wall, acting on proteins and lipopolysaccharides, changing the permeability of the cell, resulting in the death of bacteria, which is different from other fungicides. The effect of ozone on viruses is the four polypeptide chains of the capsid shell protein of the virus, and the RNA is damaged to achieve the purpose of disinfection.

1: There are many types of ozone disinfection machines, the first is a high-voltage discharge ozone disinfection machine, its principle is to generate a certain high-voltage electric field through the current when used. Then the oxygen molecules inside the electric field will undergo a chemical reaction and then make ozone.

The second type is the ultraviolet ozone disinfection machine. Ozone is produced by irradiating oxygen molecules at specific wavelengths of ultraviolet light to produce ozone under certain conditions. The third type is the electrolytic ozone disinfection machine.

The principle of this ozone machine is to produce ozone by electrolysis of purified water. 2. Ozone has very strong oxidizing properties, and can rely on this characteristic to react with bacteria to achieve the effect of sterilization.

When ozone is generated, the third atom oxygen in the ozone molecular structure will continue to be free or escape from this structure, and when it escapes, it will instantly produce great oxidation effects such as sterilization, detoxification, bleaching, and deodorization. Ozone will decompose itself into pure oxygen (O2) if it does not oxidize with other substances. The ozone generator takes advantage of this feature and uses clean oxygen to produce ozone by high-pressure electrolysis.

Three: ozone disinfection machine is mainly used for air sterilization and object surface sterilization in processing workshops and similar places in food, medicine, cosmetics and other industries, and is simply understood as a machine that uses an ozone generator to produce ozone.

Summary: The principle of ozone disinfection machine: ozone has very strong oxidizing properties, and it can rely on this characteristic to react with bacteria to achieve the effect of sterilization. I hope mine is helpful to you and I wish you a happy life

Ozone is a strong oxidizing agent, and the sterilization process is a biochemical oxidation reaction. Here's how it works::

1. Ozone can oxidize the enzymes needed to decompose glucose in bacteria, so that bacteria are inactivated and killed.

2. Directly interact with bacteria and viruses to destroy their organelles, DNA and RNA, so that the metabolism of bacteria is damaged, resulting in the death of bacteria.

3. Through the cell membrane tissue, it invades the cell, acts on the lipoprotein of the outer membrane and the lipopolysaccharide inside, causing the bacteria to undergo permeability distortion and dissolve and die.

Ozone's disinfecting effect stems from the fact that it quickly releases atomic oxygen. Atomic oxygen has the effect of destroying proteins, so it is often used for sterilization of pure air in the room dust.

Ozone. Ozone technology is both old and new, invented by German chemists in 1840 and used in the water treatment and disinfection industry in 1856.
