Carbon ( C) Powder has two categories, one is a single set of powder is a double set of powder. 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. According to its electrical divided into positive carbon powder and negative carbon powder. Using the market at present high, however, a single set of negative carbon powder. But consumers ( 消费者) Because the don't understand, often ask questions. In the face of so many types of powdered carbon, what kind of carbon powder is a good carbon powder? A: dry solid force refers to the printer toner in photocopying materials such as paper and transfer printing paper, with very good cohesiveness. 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. 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. 2: fidelity for the copier, printer toner are considering rules (300 to 1200 dpi guī叮) 。 3: black plate type printer toner, is a professional in order to increase black secret recipe, can make the blackness of printer toner particles. Four: electrical performance type plate printer toner particles by induction electrical price higher versatility powder, maintain positive work ability is strong, so the printer toner in the magnetic roller ( gǔn) — OPC— All the process transfer paper (paper 郭cheng) Maintain working voltage associated with the device, printer toner can more sufficient transfer paper to the paper, a large levels ( 减少) The residual powder. Five: fixing temperature according to different types of fixing temperature and decorate design scheme ( fāngàn) , let it can in a relatively conduct sufficient under the temperature of the melted, and various condensation in the short term, prompting printer toner fixing on the material the actual effect is stronger, and non-stick upper fuser roller, or fuser film, separate application claws are very easy to separate paper, reduce the paper card to reduce the damage to the related components. Six: low friction index of very fine particles printer toner reduces with the drum in the middle of the degree of friction, can make the photosensitive drum could the increase, and let the scraper ( Also known as the trowel) Very easy to remove the residual powder clean and tidy.
