The color mother has the following advantages:

The pigment must be refined in the process of producing the pigment in the process of producing better. The carrier of the dedicated color mother is the same as the plastic variety of the product, and it has good matching and heating and melting. The post -pigment particles can be scattered in product plastics very well. For color materials used in plastic color, it is necessary to pay attention to the relationship between the color material and the plastic raw material and the auxiliary agent. The main points of the choice are as described below.

(1) The color cannot be reaction with the resin and various additives, strong solvent resistance, small migration, and good thermal resistance. In other words, plastic -colored mothers cannot participate in various chemical reactions. If the carbon black can control the curing reaction of polyester plastic, the carbon black material cannot be added to the polyester.

High -concentration charcoal black not only provides its superior coloring intensity and cover ability, but also maintains the mechanical properties of basic plastics at the same time. With the different quality of the resin, the amount of mother's dosage can be reduced by 10-15 % compared to the current product, and the same coloring effect can be achieved. In maintaining the mechanical properties of basic plastic, such as tension strength and high processing temperature of plastic products, the color material should not be decomposed under the condition of molding heating temperature. Generally, inorganic pigments have good thermal resistance and poor heat resistance of organic pigments and dyes. This should be attracted enough attention when choosing a color variety.

(2) The scattered and colorful power of the color should be good. When the color is not uniform, it will affect the appearance performance of the product; when the color material is poor, the amount of color will increase and increase the cost of the material. The same color is not the same as the dispersion and color force in different resins, so pay attention to this when choosing a color. The size of the color material is also related to the decentralization. The smaller the particle size of the color material, the better the dispersability, and the strong color power.

(3) You should understand other properties of the color material. For plastic products for food and children's toys, plastic masterbatchs are strict; plastic products for electrical appliances should be selected ; For outdoor plastic products, color materials with good climate resistance should be selected.

Generally, the plastic masterbatch granular technology is a wet process. Plastic masterbatch female materials are grinded, rotated, washed, dry, and grained. Only in this way can the quality of the product be guaranteed. In addition, when the pigment is grinded, a series of plastic -colored parent technology should be performed, such as determining the fineness of the sand grinding slurry, the diffusion performance of the sand grinding slurry, the solid content of the sand and grinding slurry, and the measurement of the fineness of the slurry, etc. project.

Plastic masterbatchs are generally composed of three parts. The coloring agent carrier decentralizers are mixed and crushed through the high -speed mixing machine. , Significant advantages such as cleaning.
