1, characteristics of ethylene oxide
Ethylene oxide is a colorless flammable gas with a strong pungent smell. It is an efficient and broad-spectrum bactericide, which can penetrate the surface of articles and has a good inactivation effect on bacteria, viruses and fungi.
2. Sterilization mechanism of ethylene oxide
The sterilization mechanism of ethylene oxide is mainly through the protein binding with microorganisms, which makes them lose their activity. It can be combined with protein of bacteria, viruses, fungi and other microorganisms to denature them, thus achieving the sterilization effect.
3. Application scope of ethylene oxide
Ethylene oxide is widely used in medical, industrial and family fields. In the medical field, ethylene oxide is used to disinfect medical instruments and surgical instruments. In the industrial field, ethylene oxide is used to clean and disinfect production equipment and production lines; In the domestic field, ethylene oxide is used to disinfect clothes, bedding and so on.
4. Safe use of ethylene oxide
Although ethylene oxide has a good bactericidal effect, it also has certain toxicity. Therefore, we need to pay attention to safety issues when using ethylene oxide. It is necessary to control the use concentration and time to avoid long-term exposure to high concentration of ethylene oxide. At the same time, the place where ethylene oxide is used should be well ventilated.
Types, action mechanisms and applications of gas fungicides in agriculture and food industry.
1, types and action mechanism of fungicides
Gas fungicides mainly include fumigation type and aerosol type. Fumigation gas bactericide, such as formaldehyde and sulfur dioxide. It exists in the air as a gas, and it can poison and inhibit pathogenic bacteria by covering the surface of plants and infiltrating into tissues.
2. Application of gas bactericide in agriculture and food industry.
Gas bactericides are widely used in agriculture to control plant diseases, such as fumigation gas bactericide methyl bromide, which is often used in greenhouse to control downy mildew and gray mold of cucumber, tomato and other vegetables.
