Carbon powder composition is mainly by resin and carbon black, electric charge and magnetic powder ( 磁粉) And so on. It is a kind of high temperature melt into the paper fiber, resin was oxidized into gas with a pungent odor, is the people often say that ozone. If low-quality carbon powder will not only will be more big to the harm of human body, also very large effects on the environment ( 影响) 。 Use inferior carbon powder is can make human body produce complications, so small make up for you today about low-quality carbon powder can cause complications? Let small make up about it for you today. 1, infection of the respiratory system: this is mainly the lungs infection, this is common complication of pneumoconiosis patients. 2, pulmonary tuberculosis ( Internal medicine) Dust: ( Characteristics: solid particles) Workers, especially the silicon dust workers, it is very easy to suffer from tuberculosis. Color toner in print, volatile due to residual monomer in the resin is heated, produces the pungent odor, therefore national standards and industry standards of toner TVOC has carried on the strict limits. So as long as you buy printer or nonconforming product quality, won't because printing produces gas harmful to health. 3, lung and pleural mesothelioma is mainly seen in asbestos workers and lung cancer. 4, respiratory failure, upper respiratory tract and lung infection, such as pneumothorax incentive is causing decompensation of the main causes of respiratory failure, sedative and sleeping drug abuse is also one of the cause of pneumoconiosis people breathing cry of the exhaust. Part 5, chronic cor pulmonale in terminally ill patients, this is because the chronic bronchitis airway stenosis, ventilation resistance increased, there are obstructive pulmonary qi, pulmonary artery pressure, and chronic cor pulmonale. 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. Color is used in the paper in the laser printer toner fixing powder material. Black toner by bonding resin, carbon black, electronic agents, additives such as ingredients. Still need to add other color in the color toner pigment, etc.
