Feb 03, 2021
1. Ultraviolet rays
Ultraviolet rays mainly act on the DNA of microorganisms, destroying the structure of DNA, causing it to lose the function of reproduction and self-replication, so as to achieve the purpose of sterilization and disinfection. The ultraviolet lamp with suitable intensity can be selected according to the actual situation. When using a UV lamp, it only kills the surface that can be irradiated, and more attention should be paid to the installation height and service life of the lamp, and the lamp tube should be replaced in time.
2, ozone machine
The ozone sterilization mechanism uses oxidation to destroy the structure of the microbial membrane to achieve sterilization. Different types of ozone machines can be installed according to the size of the space. It is mostly used for the disinfection of cold storage and packaging materials and cooling packaging rooms, but it should be noted that ozone disinfection will corrode the equipment to different degrees. Its concentration should not be too high and the disinfection time should not be too long.
3, disinfectant
Alcohol: 75% alcohol is mainly used for wiping and disinfecting the surface of hands and small-area utensils. It is effective against bacterial propagules, some fungi, and viruses, but is not effective against spores. Because it is volatile, please pay attention to its concentration. It is best to use it up on the same day after opening ; 95% alcohol can be used to wipe the UV lamp.
