Carbon ( C) Powder quality has very many kinds of common technical standards, such as particle size and distribution, low ash, agglomerate temperature, blackness, waste powder rate, resolution, the degree, level ( The level of agency) ( 层) And so on. 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. So what is the scrap rate of? Here a brief introduction is as follows: the scrap rate, usually refers to a certain amount of carbon powder in normal printing of waste powder proportion. Carbon powder production ( 生产) The ingredients in a certain proportion to join in common, and fully stirring, the corresponding processing ( chǔ lǐ) , then through grinding. In this process ( 郭cheng) , there is no guarantee that the thickness of each carbon powder particles as well as its main ingredients of carbon powder, iron powder, resin, the proportion of the same, only is in the range of certain proportion. Beyond this range, the toner particles might ( 也许) Become waste powder. Also directly affect the amount of waste powder rate of carbon powder printed pages. Standard of waste powder rate in 5% 7% of the imported powder of waste powder rate in 6% 8% of domestic waste powder rate in 10% 15% or even more. The above information by carbon ( C) Powder suppliers & ndash; — Arrange to provide, if you want to know more information, can log on the index. 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 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.
