Colormother has the following advantages:

The pigment must be refined during the product in the product to improve the pigment to improve the dispersibility of the pigment and the coloring force. The carrier of the special colored mother is the same as the plastic variety of the article, with good matching, heating melting. The rear pigment particles are well dispersed in the articles of plastics. 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 mobility, 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 recreation 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 basic plastics, such as tension strength and high temperature due to the molding of plastic products, the color should not decompose discoloration under molding heating temperature conditions. Generally, the inorganic pigment is well heat resistance, the organic pigment and dye are poorly heat resistance, which should cause sufficient attention when selecting the color species.

(2) The dispersion of the color is good. When the color dispersion is 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 not the same in different resins, so it should be aware of this when selecting the color. 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 color strength is also strong.

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

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

Plastic master is generally consisting of three parts, colorant carrier dispersing agent, after mixing, crushing, extruding, plastic, plastic, has a high concentration, good dispersibility, cleaning Other significant advantages.
