According to the speed of laser printers print to distinguish between carbon powder, it can be divided into powder and the powder at low speed. 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. 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. Carbon powder suppliers, said the print copies per minute for not more than 10 pages of laser printer is defined as a low-speed machine; General will print number more than 14 pages per minute of laser printer machine is defined as a high speed. Is the difference between the two big low-speed machine fixing time far longer than high-speed machine and fixing component fixing temperature ( 温度) Also more than the high speed machine. So, be in commonly filled powdered carbon, low powder powder is not a substitute for a high speed. The main components of the carbon powder is resin ( Resin) Oxygen, carbon black, ( 氧气) Iron, lubricants, etc, of which iron is the carrier, and the main function of lubricant is to maximize reduce carbon powder on the photosensitive drum wear ( A basic type of component failure) And prolong the service life ( 一生) 。 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. Used in printer toner is insulation ( 绝缘) By friction produce certain static charges ( 电荷) , or is positive or negative, and have a fixed softening point. Various models of carbon powder in principle is not universal, because of its composition, charge how many different vibrations, and softening point on the properties of its requirement is mainly based on the needs of match of the printers, toner particles uniform fine ( jūn yún) , in general, the diameter of 7-12 microns. Because receives heat, ultraviolet ray, the influence of humidity and other objective factors, so the store must be in order.
