The method is characterized by direct dye coloring additives by adding an appropriate amount of powdered toner (pigment or dye) of colored plastic particles, also known as dry coloring. The advantage is good dispersion, low cost, small-batch operation. Because it obviates the other colorants, such as processing of masterbatch consumption of human and material resources, paste, and thus low cost, quality pesticide colorant, buyers and sellers from the restriction. Masterbatch manufacturer can not do 1 ~ 2kg, pesticide manufacturers colorants, but the toner can be specified quality, pesticide colorant needed to prepare very convenient. Use dye coloring, compared with other colored granules, resin processed less experience a degradation process helps to reduce the aging of plastic products and increase their service life. But the biggest drawback is the pigment in the transport, storage, weighing, mixing process will be flying, pollution, seriously affecting the work environment. As environmental, business and other requirements of ISO9000 indicators, dye coloring increasingly been limited, but for special effect color, the use of direct mixed colored toner colored masterbatch has some less than the effect. For example: Some poor heat resistance, fear sheared pigment powder made of masterbatch, which withstand high temperatures due to the long time, and for a long time by the shearing action masterbatch processing equipment, the coloring effect will be significantly weakened, such as pearlescent pigments, phosphor, luminous powder. Toner is made with pearl masterbatch and then colored plastic, colored plastic than directly mixed with pearl powder, pesticide colorant company whose pearl effect to decrease by about 10%, and injection molded products are also prone to flow linear scar and seams. In the manufacture of this type of masterbatch, are taking appropriate measures to minimize the masterbatch heated during processing temperature, time and extent of the cut (no twin-screw granulation machine, but with a single screw granulation machine ).
