Various raw materials (carbon powder 原料) ( Material) If it is a standardized manufacture and can be used in sealing condition is non-toxic, but now in the market for all kinds of bottled powder for production ( 生产) Technology conditions such as constraints, it is difficult to meet the requirements of non-toxic, also due to the carbon powder price is not cheap, saving the cost of printing problems but also worried. 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. So how should we use carbon powder to achieve this; Kill two birds with one stone. The purpose of the? First, try to use formal company ( 公司) Selenium (or brand of environmental protection 硒) ; Second: if you can't sure whether there is a non-toxic filled carbon powder, please send the printer away from the body, and placed in ventilated place; Third: try not to choose, 轩泽) Filled with carbon powder in the workplace, if necessary, under the strict environmental protection of the factory should also do filling process, and populate the qualified, standard of carbon powder; 4: if you can't in environmental conditions ( 条件) Under filling, just as far as possible in the field of the wind do to fill the places, and will be discarded waste powder and stained with carbon powder materials for incineration. 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.
