Problems solved by technology
In order to sterilize, a UV (ultraviolet) lamp 32 is installed in the working room, promptly utilizes the UV (ultraviolet) lamp to irradiate and kill organic compounds or fungi in the air, but the sterilization is not thorough. Oxygen becomes an odor. When the concentration of the odor in the air exceeds the standard, ozone is an invisible killer. It strongly stimulates the human respiratory tract, causing sore throat, chest tightness and cough, causing bronchitis and emphysema; causing human neurotoxicity. , dizziness, headache, decreased vision, and memory loss; it has a destructive effect on vitamin E in human skin, causing skin wrinkles and dark spots; it can also destroy the immune function of the human body, induce lymphocyte chromosomal lesions, and accelerate aging. Cause pregnant women to give birth to deformed children, so the ozone discharged from the biological safety cabinet will cause secondary pollution to the air
