Add printer for carbon ( C) Powder, some users in order to save money is disassembling plus powder, in such a situation, not particularly recommended users to add carbon powder. Printer toner according to different requirements, the carbon powder production to develop in the direction of refinement, color and high speed. Carbon powder manufacturing mainly adopts FenSuiFa and polymerization. Mainly because the toner particles is very small, whether it is printed in the normal working state, or in the absence of protection under the state to the drum filling carbon powder, will be part of the carbon powder flying into the air, will be recycled after being inhaled ( 继续) To the human kidney ( Carbon powder is too small and does not dissolve in water, lung to filter, out of the body) , the chances of cancer will be about 10% higher than normal, cause kidney stones ( 肾结石) 3 times higher than normal risk of symptoms. Selenium ( 硒) Drum in the absence of strict environmental protection filling powder, small particles of molecules ( To the naked eye can see) Will be flying in the air, the human body contact many times when inhaled, the risk of cancer will be about 10% higher than normal, and the surface modification agent polyethylene/polypropylene wax ( 蜡烛) Drawn into the body, its small molecular particles will be absorbed to the circulation of the blood ( 继续) System, the vegetation in the kidney, is very not easy to be out ( Because the carbon powder insoluble and water) So as to cause kidney stones and other disease risk is three times higher than normal. Carbon powder polymerization is a kind of fine chemical toner technology, it includes suspension polymerization, emulsion polymerization, detail capsule, dispersion polymerization, compression polymerization, chemical pieces. Printer toner many drums in original toner after use, the user can add after used again, so also is to have separate toner for sale on the market. By adding toner by oneself, will reduce the use of the user supplies cost. When users add carbon powder, actually don't know toner particles ( Content: atoms, molecules, ions) Already in the process of add powder has entered the trachea, has entered the pores. Toner particles is based on nanometer units ( 单元) Invisible to the naked eye, in imperceptible in damaged their own health. So add powder, must be done in a protective measures.
