What are the disadvantages of car ozone disinfection?
1 Answers
Ozone is a strong oxidizing agent that can damage various items. The higher the concentration, the more severe the damage to items. It can cause green rust spots on copper sheets, aging, discoloration, and reduced elasticity of rubber, leading to brittleness and breakage, as well as bleaching and fading of fabrics. Ozone also irritates the mucous membranes of the human respiratory tract. At concentrations of 0.5-1 ppm, it can cause discomfort such as dry mouth. Therefore, ozone disinfection must be conducted in the absence of people, and entry should be avoided for at least 30 minutes after disinfection. More details are as follows: 1. According to international standards, concentrations of 0.5-1 ppm can cause discomfort such as dry mouth; 1-4 ppm can cause coughing; and 4-10 ppm can cause severe coughing. 2. Ozone disinfection is an allotrope of oxygen, gaseous at room temperature, highly reactive chemically, very soluble in water, and has extremely strong oxidizing capabilities. 3. The oxidizing power of ozone can be used for sterilization and disinfection. When ozone encounters bacteria, it immediately undergoes an oxidation reaction, thereby achieving functions such as sterilization, mold removal, odor elimination, and decomposition of harmful gases. The oxygen left after the reaction does not pollute any items in the car. 4. The ozone sterilization and disinfection process takes 15 to 30 minutes. After completion, the car owner should not enter the vehicle immediately but should leave the doors open for a few minutes to allow any remaining ozone to fully react before entering. Due to its strong oxidizing properties, ozone can pose certain hazards to human health.
