Is a 4-watt UV lamp useful for chopstick sterilizing boxes?

Useful, 4W power is enough to disinfect chopsticks

Ultraviolet light can disinfect chopstick pillows.

1. Place the chopstick pillow under an ultraviolet germicidal lamp or the sun to use ultraviolet rays to sterilize. Short-wave ultraviolet rays are extremely destructive to microorganisms. When ultraviolet rays in this band irradiate bacterial cells, the cells will Nucleoprotein and deoxyribonucleic acid (DNA) strongly absorb the energy of this band, and the chains between them are opened and broken, causing the bacteria to die. For example, use ultraviolet mercury lamps or metal halide lamps to sterilize air and food.

2. Under the irradiation of ultraviolet rays, the strongest UV absorption peak of DNA, ribonucleic acid and nucleoprotein in bacteria is at 254~257nm. After bacteria absorb ultraviolet light, it causes the DNA chain to break, causing the cross-linking of nucleic acids and proteins to break, killing the biological activity of nucleic acids, and causing the death of bacteria. It is fast and convenient, and there is no secondary pollution because there is no physical contact.

Wooden chopsticks will change color over time when sterilized in infrared rays, and plastic chopsticks will deform, become brittle, and then break. Therefore, do not use infrared rays to sterilize any plastic utensils, but there is no problem using ozone for sterilization.

Disinfection cabinets use ultraviolet, far-infrared, high temperature, ozone and other methods to dry, sterilize, keep warm and dehumidify tableware, tableware, towels, clothing, beauty and hairdressing equipment, medical equipment and other items. Tools are generally in the shape of a cabinet, and most of the cabinet body is made of stainless steel.

According to use, it can be divided into: commercial disinfection cabinets and household disinfection cabinets.

Clothes disinfection cabinets and other household disinfection cabinets are generally similar to those used in hotels. Many household disinfection cabinets use built-in disinfection cabinets in order not to take up space. The other differences are only in the size of the product model. That’s all.

According to the disinfection method, it is divided into: high-pressure steam tableware sterilization cabinet, electric tableware sterilization cabinet, ozone tableware sterilization cabinet, ultraviolet tableware sterilization cabinet and combined tableware sterilization cabinet.

According to the disinfection effect, they are divided into: one-star disinfection cabinet and two-star disinfection cabinet.
