The main component of carbon powder is not carbon, and most of the resin and carbon black, charge agent, magnetic powder and other components. Toner Cartridge is melted into the paper fiber at high temperature, the resin is oxidized into a gas with a stimulating odor, which is what we call 'ozone'. This kind of gas has only one advantage, is to protect the earth, reduce the harm of solar radiation. On the human body itself is no good, will cause irritation to the human mucosa, easy to improve the incidence of asthma or nose allergies, and even dizziness, vomiting and so on. And some substitute powder, mostly using carbon black as raw materials, containing polycyclic aromatic hydrocarbons and dimethyl nitramine and other substances, which were three or four carcinogenic substances. These substances are used in the laser printer and the printer to add the supplies, a laser printer with magnetic Toner Cartridge (carbon), the use of magnetic Toner Cartridge, Powder) Main components: F-Fe3O4 crystal powder (PLGMENT): 20-30% Polyacrylate-styrene copolymer: 50-60% Charge regulator CCA: 10-20% Flow agent SiO2 Surface Modifier Polyethylene / Polypropylene Paraffin II, Non-Toxicity Control of Toner Cartridge A variety of raw materials such as Toner Cartridge can be non-toxic if it is used in a sealed state (eg original manufacturer or Mitsubishi Toner Cartridge, , Central China toner, etc.). According to AMES-test, the current market, a variety of bottled loose powder due to production technology and other conditions are difficult to meet the non-toxic requirements. Third, the market part of the toner is toxic on the market Many bulk or bottled Toner Cartridge (origin, site unknown) due to its plant equipment, technology, raw materials, environmental and other factors, particles ranging from 5-12 microns , The size of a large deviation. Polyvinyl acrylate-styrene copolymer polymerization, that is, molecular weight and distribution is critical, too large can not fix (resulting in false blackness), too small is a small molecule of toxic styrene gas escape, the human body for a long time in the Close to the use of such toner printer environment, will cause harm to the human body, the probability of cancer than normal will be 4% higher, and will pollute the OPC drum and MR magnet roller, resulting in poor print cartridge. Toner is divided into magnetic toner and non-magnetic toner, and each machine model used in the toner composition ratio is different. Many bottled toner or bulk toner are no distinction, only a mixture of magnetic toner, with the wrong toner or poor quality when the toner is not just harmful to the human body and the environment, and will damage the printer and affect the printer life. Fourth, fill the potential harm to human health Toner cartridges in the absence of strict environmental protection in the case of filling powder, which small particles (the naked eye can not see) will fly in the air, the human body after exposure to inhalation, the risk of cancer More than 10% higher than normal, and the surface modifier polyethylene / polypropylene paraffin is inhaled into the body, the small particles will be absorbed into the blood circulation system, the final vegetation in the kidney, very easy to be Discharge (because the powder insoluble and water), which induced kidney stones and other symptoms than normal to 3 times higher than normal. 5, the general harm to the Toner Cartridge in the filling of the toner at the same time the amount of carbon powder per gram can be polluted 0.8 cubic meters of land. Original manufacturers or Mitsubishi, Bachuan, Central China and other manufacturers can control the waste powder within 5%, while the market common bottled powder waste powder are about 10%. Environmental toner cartridges in its standard manufacturing waste powder will be produced as a raw material for the production of low-end copier with toner, thereby eliminating the harm to the environment. 6, the hazards of toner in the actual work of the control measures recommended in order to effectively eliminate or reduce the harm to the human body and the environment, but also save the cost of printing, experts make the following recommendations: 1) try to use regular companies or brands 2) When you can not determine whether the filled toner is non-toxic, please keep the printer away from the body and place it with ventilation, such as the use of copiers. 3) Try not to fill the toner in the workplace. 4) If you can not fill in the case of environmental protection, as far as possible in the wild filled with air, and the waste of waste powder and stained with toner material burned.
