It can be used for disinfection and sterilization of utensils, towels, handkerchiefs, syringes, and other articles that are not afraid of moisture and are resistant to high temperature.
2. natural disinfection method: natural disinfection method is called to kill pathogenic microorganisms by using natural conditions such as sunlight to achieve the purpose of disinfection.
In the sunlight exposure method, sunlight has certain bactericidal power due to its heat, dryness and ultraviolet rays. The germicidal efficacy of sunlight is influenced by factors such as region, season and time. The stronger the sunlight, the longer the irradiation time and the better the germicidal efficacy. The ultraviolet rays in sunlight are weakened by heat dissipation and absorption when they pass through the atmosphere, and they can't all pass through the glass. Therefore, they must be exposed directly in the sun to achieve sterilization effect.
