1, quality is bad, copier toner, in wet and big temperature change environment, the use of storage time is a bit long, will produce agglomerate phenomenon, in use process can produce damage to developing warehouse parts, thus affect the imaging quality, even will shorten the service life of developing warehouse ( 一生) 。 2, copy machine by ( tōng郭) Upper fuser roller to melt carbon powder, and then through the pressure of upper and lower axis, the powdered carbon fixation on the paper, different copier, fuser roller heating temperature will have a deviation, wide melting point of carbon powder, upper fuser roller with good performance with different photocopiers, on different copier has good print quality. 3, melting point range ( fàn wéi) Narrow toner, print quality is not stable, Explanation: solid stability; There is no change) When the carbon powder melting point higher than the upper fuser roller ( gǔn) Heating temperature, carbon powder melting is not complete, can't completely infiltration of paper fibers, causing the image fixing fragile; And when the carbon powder melting point is lower than the upper fuser roller heating temperature, excessive softening toner, stick on the upper fuser roller, fuser roller, pollution easy ceng dirty paper that how to determine the carbon powder, ok? Can use the following 10 method to judge out 1, copier toner bouquet: no odor or microstrip fragrant 2, the appearance of the carbon powder, no impurity, no condensation ( 冷凝) Block 3, liquidity: high quality carbon powder liquidity is very good, compatibility: refers to the compatibility between 5 powder and powder, powder consumption: each copy of a piece of paper by the weight of the carbon powder 6, fixed on: see the typescript surface roughness ( cū cāo) Or smooth, stability: from the beginning after add powder to printed the stability without exception all 8 will powder, bottom ash: look at the test print proof do you have any words in the blanks the blackness values of 9, fixing fastness: attached on the surface of the paper, toner after melting to infiltrate ability of 10, waste paper fiber powder rate: waste powder rate refers to a certain amount of carbon powder in normal printing of waste powder proportion. 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 polymerization toner used widely, because of the high cost, mainly used in the production of color toner. In general, judge the quality of the carbon powder need professional tools to test, the above method, it is master some technical experience ( 经验) Summary ( zǒng杰) , in the absence of professional testing tools, can use the above method to determine the quality of the carbon 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.
