Selenium drums belong to the ninth category of crystal and carbon materials for scientific instruments, electronic products and security equipment.
Selenium drums, also known as photosensitive drums, are C969 selenium piles and selenium sheets for electronic and electrical common components.
Electronic computers and their external equipment 972 printers and copiers. The selenium drum not only determines the quality of printing, but also determines how much money users need to spend in the process of using it. In the laser printer, more than 7% of the imaging components are concentrated in the selenium drum, and the quality of printing is actually determined by the selenium drum to a great extent.
Selenium is a nonmetallic chemical element, and its chemical symbol is se. It can be used as photosensitive materials, catalysts for electrolytic manganese industry, essential nutrients for animals and beneficial nutrients for plants.
