Nowadays everyone has begun to pay attention to controlling viral infections and cutting off the passage of the suction channel. "Disinfection" has become a hot word in our lives because it is to prevent infectious diseases. The following overview of the performance characteristics of each provides users with sufficient information to select an appropriate disinfectant for any item and use it in the most efficient way.
What is disinfection?
Disinfection-refers to the act of killing or removing pathogenic microorganisms to make them harmless. Among them, viruses and bacteria that can cause diseases are pathogenic microorganisms. They are all part of microorganisms.
What are microorganisms?
Microorganism: refers to a large group of organisms including bacteria, viruses, fungi, and some small protists, microalgae, etc. It is small and closely related to humans. It covers many types of beneficial and harmful, and widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, sports and so on.
The existence of microorganisms can be traced back hundreds of millions of years ago. Their tenacious vitality and terrible reproductive ability have made them develop to this day. It can be said that these microorganisms are the oldest existing in the history of the earth. Important link.
For viruses and bacteria, the mechanism of disinfection is mainly divided into two types, one is to directly act on internal genetic material, such as ultraviolet light and ozone; the other is to inactivate its protein, such as the use of high temperature and chemical reagents.
1 Disinfectant disinfection
Disinfectants belong to chemical disinfection reagents, such as 84 disinfectant, 75% disinfectant alcohol, etc. The principle of disinfectant is mainly to change the permeability of the cell membrane of pathogenic microorganisms, interfere with or destroy the protein structure of pathogenic microorganisms, so as to achieve The role of sterilization.
As disinfectant disinfection is simple and easy to operate, and there are many types of disinfectants, it is also widely used. Recently, because of the new coronary pneumonia, many disinfectants and hand sanitizers have been in short supply, in short supply.
It should be noted that because of the ingredients, the disinfectant is somewhat corrosive and has some damage to the skin. There are also certain contaminant residues after use, such as chlorine compounds, so when we disinfect the private car, do not It is recommended to use this type of contact disinfection; similarly, they need to be stored in a sealed or cool environment. For example, alcohol has volatile and flammable properties. When it is close to a fire source, it may explode and affect the safety of people. Therefore, when spraying and disinfecting with alcohol, we must stay away from fire sources to avoid unnecessary personal injury.
2 High-temperature disinfection
High-temperature sterilization is a very traditional and effective method of sterilization, the most common of which is boiling water. It uses high temperature that exceeds the maximum growth temperature of pathogenic microorganisms to cause irreversible damage to the proteins and nucleic acids of the pathogenic microorganisms, thereby achieving the effect of sterilization and disinfection.
3 UV disinfection
Ultraviolet rays and ozone are the two great gods in physical disinfection. They can directly attack the core genetic material of the pathogen and accurately kill it.
At present, the most common ultraviolet disinfection methods are sunlight irradiation disinfection (with ultraviolet rays in sunlight) and ultraviolet lamp irradiation disinfection; although ultraviolet disinfection has the characteristics of fast disinfection, colorless and odorless, and can be directly inactivated. However, because ultraviolet rays can only be directly irradiated, and the penetration is not strong, if there are objects covered by the irradiation, it is easy to produce more disinfection dead spots; in addition, because the lamp tube of the ultraviolet lamp is prone to dirt after long time use, It directly affects the penetration of ultraviolet light, which greatly reduces the effect of sterilization and disinfection.
Because ultraviolet rays are colorless and odorless, direct irradiation has certain harm to the human body, etc., so ultraviolet disinfection should be carried out in a confined space, and people must leave the disinfection area and wait for the ultraviolet lamp to stop working before returning; After disinfection, there is a certain resurrection of bacteria under dark or light conditions, which affects the disinfection efficiency.
04 Ozone disinfection
The principle of ozone killing viruses is accomplished by directly destroying ribonucleic acid or deoxynucleic acid. The scope of ozone sterilization and disinfection is very wide, it can kill bacterial propagules and spores, viruses, fungi, etc., and can also destroy botulinum toxin.
Ozone disinfection characteristics
1. Ozone is a gas. It is in a free state in the air. It diffuses quickly and has a strong diffusion. It has a strong sterilization effect on bacterial viruses and unsprouted spores. There will be no dead ends in anti-virus. As long as it is in a sealed state, ozone can sterilize any objects in the sealed space without dead corners.
2. The speed of ozone sterilization is very fast. Research data shows that the ozone disinfection effect is 600-3000 times that of chlorine.
3. The oxides produced in the process of ozone sterilization are non-toxic, odorless, and can be quickly decomposed into oxygen without secondary pollution; if ozone is placed in the drinking water, seawater or sewage of breeding water, it can increase the dissolved oxygen in the water The amount is good for purification, so ozone is called a universal disinfectant.
4. Ozone is generated locally in the application, which is very simple, complete, economical and affordable. As long as an ozone disinfection machine can be used with production.
In life, the first three sterilization methods may be used more, but there will be some chemical residues in the disinfection solution to clean tableware; drinking water must be boiled at a high temperature if you want to completely disinfect it; use ultraviolet light to disinfect the room, because the furniture is blocked and Due to the limitation of light intensity, there are more dead ends ...
In this way, the ozone disinfection method, ozone as a free gas, can cover a full range, good diffusivity and uniform concentration, no dead ends, better disinfection effect, the oxygen generated after disinfection is healthy and pollution-free, an ozone disinfection machine can be Compared with other disinfection methods, the ozone disinfection effect is better and healthier.
