Colormother has the following advantages:

The pigment must be refinered during the product in the product to improve the pigment to improve the dispersibility of the pigment and the coloration. The carrier of the dedicated color mother is the same as the plastic variety of the article, with good matching, heating melting. The rear pigment particles can be well dispersed in the articles of plastics. The color of the plastic masterbatch must pay attention to the matching relationship between the color material and the plastic raw material, the auxiliary agent, and its choice is as follows.

(1) Color materials cannot be reacted with resins and various auxiliaries, solvent resistance, small migration, good heat resistance. That is, the plastic master cannot participate in various chemical reactions. Such as carbon black can control the curing reaction of the polyester plastic, so the carbon black material cannot be added to the polyester.

High concentration carbon black, not only provides its superior color strength and covering ability, but also maintains the mechanical properties of basic plastics at the same time. With the different quality of the reconstruction resin, the color mother is used to reduce the current product by 10-15%, and achieve the same coloring effect. In maintaining the mechanical properties of the basic plastic, such as tension strength and high temperature in the molding of plastic products, the color should not decompose discoloration under molding heating temperature conditions. Generally, the inorganic pigment is preferably heat resistance, and the organic pigments and dye heat resistance are poor, which should cause sufficient attention when selecting the color species.

(2) The dispersion of the color, should be good. When the color is dispersion uneven, it will affect the appearance of the article; when the color is colored, the amount of color is increased, and the material cost is improved. The same color is different from the dispersibility and coloration in different resins, so it should be aware of this when the color is selected. The particle size and dispersibility of the color are also related, the smaller the particle size of the color, and the better the dispersibility, and the coloring force is also strong.

(3) There should be other properties of the color, such as for plastic products used in food, children's toys, plastic master requirements; plastic products for electrical appliances, should be selected from electrically insulating color; For outdoor plastic products, color aging resistance should be selected.

The generally used plastic masterbatch technology is a wet process. The plastic masterbatch is polished by the water phase, transparent, washed, dried, and granulated, only such product quality can be guaranteed. Further, the pigment should also perform a series of plastic master technology to detect, such as determining the diffusion properties of the sand slurry, determine the solid content of the sand grinding slurry, and the measurement of color pastelation. project.

The plastic masterbatch is generally consisting of three parts, colorant carrier dispersing agent, after mixing, crushing, extruding, plastic granulation, plastic masterbatch during plastic processing, good dispersibility Significant advantages such as cleaning.
