Disinfection spray is a common method for disinfecting air and surfaces in closed environments. For example, the new guidelines for the use of disinfectants issued by the new office of the Health Commission clearly state that spray disinfection with peracetic acid or hydrogen peroxide is an effective disinfection method. Compared with peracetic acid, the hydrogen peroxide sprayed by the hydrogen peroxide sterilizer is milder. After the outbreak of the new crown, the application of hydrogen peroxide sterilizers has become more and more extensive. For air and surface disinfection.
Peracetic acid or hydrogen peroxide sterilizer can be used for disinfection, but according to different principles, there are two methods of hydrogen peroxide sterilization sprayed by hydrogen peroxide sterilizers commonly used in the market. One is vaporized hydrogen peroxide, the other is hydrogen peroxide dry mist, that is, hydrogen peroxide spray aerosol, these two methods are completely different. Vaporized hydrogen peroxide is a method of heating, flashing hydrogen peroxide above 110 ° C to form steam, which is completely gaseous and diffuses in the air. Atomized hydrogen peroxide is a high-pressure nozzle or ultrasonic wave, which disperses the hydrogen peroxide solution into 3-50um aerosol liquid particles suspended in the air and diffuses in the form of Brownian motion.
The disinfection methods of peracetic acid or hydrogen peroxide sterilizer are very similar, and many experts can’t tell the difference. However, the hydrogen peroxide sterilizer has been widely used in the market, and has been widely praised by consumers for its safety and good disinfection effect!
