At the beginning of this year, the huge infectiousness of the coronavirus disease made everyone's health and safety more important than ever.
According to relevant statistics, under the epidemic situation, people's enthusiasm for disinfection products is unprecedentedly high. Even if the price of 28% disinfection equipment is increased by 20-50%, and the price of 9% of products is increased by more than 50%, it is still difficult to stop people's enthusiasm for consumption.
After the disinfectant was developed and used, various problems followed. For example, among the common disinfectants, quite a few disinfectants are low-toxic and corrosive to metals and fabrics. The more well-known is chlorine-containing disinfectant, which is toxic and cannot be used in acidic environments (mixing with hydrochloric acid-containing toilet cleaner will produce chlorine gas). At the same time, long-term inhalation of low-concentration chlorine can also cause chronic poisoning and cause chronic bronchus Inflammation, emphysema and liver cirrhosis.
For this reason, a series of quantitative and timed sterilization equipment came into being. According to the approval of the Ministry of Health, pressure steam sterilizer, ethylene oxide sterilizer, glutaraldehyde sterilizer, plasma sterilizer, Ozone disinfection cabinet, electric disinfection cabinet, electrostatic air disinfection machine, ultraviolet germicidal lamp, ultraviolet sterilizer, formaldehyde disinfector, acid oxidation potential water generator, sodium hypochlorite generator, chlorine dioxide generator, ozone generator, ozone water generator and Other disinfection equipment (specify disinfection and sterilization factor).
Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde, etc.) , Bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
1. The air purifier does have a certain effect. While improving indoor air quality, it also correspondingly improves the health indicators of indoor people. Studies have shown that turning on the air purifier during the day can reduce the PM2.5 concentration from 6-7 units to 1-2 units.
2. After turning off the air purifier, the indoor PM2.5 concentration quickly rises; even if the doors and windows are closed from night to early morning, the indoor PM2.5 concentration will continue to rise to 4-5 units within 3 hours after the purifier is turned off .
3. Studies have also shown that indoor pollutants are not only PM2.5. Closing doors and windows for a long time, increasing the concentration of indoor carbon dioxide, etc., and the trace ozone generated by various electrical appliances may harm human health.
