The organic pigments are mainly carbon black, azo pigments, phthalocyanine, quinoline ketone, isoindolinone, anthraquinone, thioindigo pigments and various chemical, wherein the carbon black is the most common black pigment used, it has a price Lim color fastness, good dispersion, good liquidity advantages of plastic while it is endowed conductivity and UV degradation of good candidates and so filling. Ideal coloring agent can make a lot of requirements, such hope it colorful, coloring force, not easily dispersed evenly in the plastic aggregation, high heat resistance and no effect on the flow of plastic, does not affect the resin and resistance to aging Its other performance, weather Fast and inexpensive, non-toxic and so on. But the biggest drawback is the pigment in the transport, storage, weighing, mixing process will be flying, pollution powdered colorants company, seriously affecting the work environment. As environmental, business and other requirements of ISO9000 indicators, more and more confined to the powdered dye coloring colorants Which high-volume, but for special effects coloring, using colored toner mixed directly with a number of colored masterbatch reach results . For example: Some poor heat resistance, fear shear pigment powder made masterbatch, which withstand high temperatures due to the long period of time, but by the shearing action of the masterbatch processing equipment manufacturers long powdered colorants, coloring effect will be significantly weakened, such as pearlescent pigments, phosphor, luminous powder. Toner is made with pearl colored plastic masterbatch then compared directly mixed plastics coloring pearl powder, pearl effect its going to weaken by about 10%, and injection molded products are also prone to flow linear scar and seams. Powdered colorants, are taking appropriate measures in the manufacture of this type of masterbatch, masterbatch minimize heat during processing temperature, time and extent of the cut (no twin-screw granulation machine, but with a single screw granulating machine, etc.). Which high-volume powdered colorants _ Weifang Fuyuan (certified) _ powdered colorants provided by Environmental Science and Technology Co., Ltd. Weifang Fuyuan.
