Six common methods of vehicle disinfection are their advantages and disadvantages.
  • Automotive

The cabin is a relatively closed space. The interior of the car, carpets, seats and dashboard are very easy to hide and dirt. It is only to keep the clean environment in the car to ensure the health of the passengers. In addition to regular cleaning of vehicles, disinfection is also an effective way to ensure clean air in the vehicle. At present, the main methods of automobile disinfection are as follows: chemical disinfection, ozone disinfection, ionic disinfection and photocatalyst disinfection. The following several disinfection methods are briefly introduced. 1. chemical disinfection. The main purpose is to use some disinfectants to spray and wipe the car parts, through chemical action to reach the purpose of getting out the germs. This sterilization method is easy to operate, and the germs are completely killed. At present, the common chemical disinfectants on the market are peracetic acid and 84 disinfectant. The method is thorough disinfection, but there will be odor in the cabin after disinfection, and ventilation needs to be ventilated for a period of time. Disadvantages: it is easy to leave chemical residues, causing potential hazards, and at the same time damaging automobile parts. Chemical disinfectants are generally corrosive and bleach. When used, they need to be careful with interior trim and metal parts. 2. ozone disinfection. A special sterilizer is used to disinfect quickly. Ozone is an efficient, broad-spectrum and fast bactericide. It can kill many kinds of germs and microorganisms. When it reaches the prescribed concentration, it can be completed quickly. Ozone can also remove toxic gases from vehicles by oxidation. Unlike chemical disinfection, ozone is used to sterilize no harmful substances, and the ozone is quickly decomposed into oxygen after sterilization and will not cause two pollution to the car. After disinfection, there will be some ozone odors in the cabin. As long as the windows are opened and ventilated for a while, the smell will disappear. Ozone disinfection operation is very simple, a car special sterilizer hose into the car cabin and open the car air conditioning, using air conditioning air circulation to the high concentration of ozone in every corner of the car, so a few minutes. Although the disinfection time is very short, the eradication of germs is very thorough. Disadvantages: if ozone disinfection is used for a long time, the rubber in the car will be aged. Moreover, the quality of ozone machine in the automobile beauty salon is not good, but the price of each disinfection is also different. 3. steam disinfection. Steam disinfection is a relatively traditional method of cleaning automobile air. The practice is to clean the vehicles with ordinary cleaners and wipe them with protective agents or dry cleaning nursing, clean the car room, carpet, foot pad and seat cover, then spray cleaning agent and bactericide in the car, and then disinfect with steam steam. Fungicides contain enzymes that break down the source of odors and eliminate odor and bacteria. Shortcomings: because of the complex operation, the long disinfection time, the serious pollution in the car is not ideal, and the steam may have bad effects on the electronic system production in the car, so it is not used much at present. 4. ion disinfection. Mainly through the purchase of on-board oxygen bar release ions to achieve the purpose of air fresh in the car, he is just a fresh and clean air way, the advantages of simple use, the shortcomings of the slow process of air purification, sterilization is not thorough. 5. photocatalyst disinfection. Titanium dioxide is a kind of photocatalyst, which can produce positive and negative electrons after light, in which the positron combines with the water molecules in the air to produce oxygen free radicals with oxidation decomposition ability, and the negative electrons combine with the oxygen in the air to synthesize the reactive oxygen species. Both hydrogen and oxygen free radicals and reactive oxygen species have strong effective bactericidal ability, which can decompose the common compounds such as formaldehyde, ammonia and benzene in the car, and can also remove floating bacteria in the car. Titanium dioxide can be fixed in the car with a special resin, so the disinfection effect is lasting. It can be maintained for about 2 years and the cost is low. Disadvantages: titanium dioxide can only be produced under ultraviolet light, and ultraviolet radiation has some harm to the human body. Some car stickers will obstruct ultraviolet rays, which will affect the efficacy of photocatalyst disinfection. 6. activated carbon disinfection of activated carbon is the most effective, safest and easiest way for car owners. Activated carbon has many pores, and has strong adsorption on formaldehyde and other harmful substances. The smaller the particle is, the better the adsorption effect is. If you are not satisfied with the air in your car, you may go to the store to buy some activated carbon air purification device. Moreover, the use of activated carbon is a physical method, which will not cause two pollution and can be used safely. Several common disinfection methods are given above. How often should they be sterilized in the vehicle? According to expert analysis, in the season of pathogenic bacteria easy to sing, such as spring, if the car owners stay in a longer time every day, more people in the car, the frequency of disinfection can be higher.
