As the saying goes, "the disease comes from the mouth." With the improvement of the national knowledge level, health knowledge has also become popular, and people pay more attention to health and health than ever before. In Guangdong, when people go to restaurants to eat, they usually use hot water to heat the tableware for peace of mind. Before the popularity of the dishwasher, ordinary households will have a disinfection cabinet at home, which will also play a role in disinfection and storage. However, the improper use of some disinfection cabinets may cause harm to the health of users. The final disinfection cabinet becomes a "poison cabinet".
At present, the disinfection cabinets on the market generally adopt high-temperature disinfection, ultraviolet disinfection, ozone disinfection and other disinfection methods. Among them, ultraviolet disinfection and ozone disinfection are low-temperature disinfection, and the temperature at which the disinfection cabinet is disinfected is generally 60 degrees Celsius. Ultraviolet light is a general term for radiation from 10 nm to 400 nm in the electromagnetic spectrum. The disinfection band is 100 nm to 200 nm. The UV disinfection effect of 253.7 nm is the best, which can kill various microorganisms, but the UV penetration ability. Weak, unable to disinfect areas that are not exposed.
Therefore, the general disinfection cabinet uses a combination of ultraviolet and ozone disinfection methods. In addition to the use of UV disinfection, ozone can also be used to generate ozone. Ozone is a light blue gas with a special odor. Under the strong oxidation of ozone, various components in the microbial cells react to cause irreversible changes and die. It is generally believed that ozone killing viruses are accomplished by directly destroying ribonucleic acid or deoxyribonucleic acid. Ozone can cause harm to the human body, but its stability is not high, and it is easily decomposed into oxygen at normal temperature and pressure.
High-temperature anti-virus refers to the use of far-infrared heaters to heat the air or generate radiant heat, so that the air temperature in the disinfection cabinet is greater than 100 degrees Celsius, and through continuous heating, the microbial protein tissue on the surface of the tableware is denatured, thereby killing the bacterial virus. Heating generally lasts for more than 15 minutes.
Based on the disinfection principle of the sterilizer, some of the contraindications arise during the process of using the sterilizer.
The disinfection cabinet cannot be opened during the operation of the disinfection cabinet. Regardless of which disinfection method is used in the disinfection cabinet, it is harmful to the human body to switch the disinfection cabinet at random when the disinfection cabinet is in operation. For example, high temperature disinfection will burn the user's skin. The disinfection cabinet with ozone disinfection generally enhances the sealing performance of the disinfection cabinet when designing. The ozone concentration of the disinfection cabinet gradually increases during operation. If the human body inhales ozone, it will cause neurotoxicity, dizziness, headache, decreased vision, memory loss, etc. Long-term exposure to ozone will destroy the vitamin E in the human body, wrinkle the surface of the skin, and even destroy the body's immune function and induce lymphatics. Cell tumor. Therefore, in addition to the disinfection cabinet can not open the disinfection cabinet during the work process, after the disinfection cabinet has completed the disinfection work, it should be allowed to stand for a while, waiting for the ozone to completely decompose into oxygen and then open the disinfection cabinet.
Disinfection cabinets are not cupboards and cannot accommodate dishes. Under normal circumstances, the cleaned tableware should be placed in a clean and ventilated environment, and the sterilizer is a closed space. The dishes are stored in the sterilizer for a long time, which will breed bacteria, especially the dishes that are not drained. Sufficient, temperature-friendly environment, the disinfection cabinet eventually becomes a petri dish. This is also the main reason why sterilizers have been used as cupboards for a long time. In addition, the tableware should be drained before the tableware is disinfected, and the moisture enters the cabinet. Because the internal environment is closed, it is difficult to discharge. The disinfection cabinet should be disinfected 1 or 2 times a week. If the disinfection cabinet is left unused for a long time, the humid air inside the cabinet is difficult to discharge. In the long run, the air will corrode the internal components, causing a short circuit, and the power supply will be damaged.
Not all tableware is suitable for putting it into the disinfection cabinet. The Chinese people's food culture is profound and profound, and the use of tableware is also varied. However, the disinfection cabinet is not a panacea. Plastic, colored porcelain and glass tableware should not be placed in a disinfection cabinet with high temperature disinfection. High temperature sterilization uses a temperature higher than 100 degrees Celsius. It is easy to melt plastic tableware. Finally, not only the tableware and the interior of the disinfection cabinet are stuck together, but also harmful substances are released. Porcelain tableware is generally colored with enamel or pigment. In a heating environment of more than 200 degrees Celsius, pigments containing cadmium and lead may overflow, and the use of these tableware again may cause damage to human health.
The disinfection cabinet enters the home with a healthy sign, but the misuse in daily life has hidden dangers for safety. Therefore, before using the disinfection cabinet, you should know the relevant knowledge and help yourself to better use the disinfection cabinet to avoid disinfection. "Under poisoning."
