For the classification of the toner, said that it can be roughly divided into two kinds, one is a two-component toner, 2 it is single-component toner. 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. Are mainly introduced here bicomponent toner composition, it is made of resins, dyes, charge regulator, the auxiliary additives, carrier, etc. , is the use of tiny carrier of the toner particles with larger particles to cooperate together, detailed as follows: (1) resin ( Resin) 。 Carbon powder polymerization toner used widely, because of the high cost, mainly used in the production of color toner. Resin in about 80% of the proportion of toner, toner is actually a dyed the color of the hot melt resin, its role is in the process of image fixing ( 郭cheng) All kinds of ingredients, the toner by ( tōng郭) Heat, pressure is fixed on paper. So the performance of the resin is crucial to the quality and stability of the toner, usually used to make toner resin is to choose adhesive performance and thermal performance is good, the chemical stability of synthesis ( Explanation: from the merger of several parts into a whole) Resin, such as acrylic acid, styrene, phenol, 苯酚) Aldehyde resin and so on. Second, the dye. 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. Dye in about 10% of the proportion of toner, main color effect. Usually in black toner using carbon black as coloring material, its chemical properties ( The parameters of the chemical reaction) Also more stable, Explanation: solid stability; There is no change) 。 Third, the charge regulator. The charge regulator is a kind of used to control ( 控制) Toner charged performance additives, the percentage is about 5%. Fourth, carrier. Carrier is the magnet powder, plastic beads and glass beads as the raw material made of, which is commonly used for ferromagnetic powder. Five, the auxiliary additives. In the toner auxiliary additives are added in order to improve the liquidity of toner, easy to clean, easy to transfer and prevent the caking, general proportion was 5% in the toner.
