The active carbon has strong adsorbability, can adsorb impurities such as dust in the air, and has a purifying effect on the air. But the effect is single, and the sterilization effect can not be achieved. Ultraviolet lamps are also a common disinfection device, which mainly utilizes ultraviolet rays for sterilization, when organic pollutants pass through an ultraviolet irradiation area, the ultraviolet rays penetrate through cell membranes and cell nuclei of organisms, and are absorbed by base pairs of DNA or RNA to generate photochemical action, so that genetic materials of the cells are changed, the activity of the genetic materials of the cells is lost, and microorganisms cannot reproduce or die in the near future. However, sterilization using an ultraviolet lamp requires electric power, and for equipment in a closed space, electric power is not always supplied. Especially, the ultraviolet ray can accelerate the aging of the files, and is not suitable for the file cabinet; in addition, the use of desiccant is not well suited for file storage, and the files will become brittle.
