色母粒知识（Color knowledge） First, the meaning of color. Color is the extraordinary amount of pigment uniformly loaded and attached to the resin prepared aggregates. And one kind of Color Masterbatch, color masterbatch (ColorMasterBatch) is a kind of special type polymer colorant, pigment preparation (PigmentPreparation). It consists of three basic elements of a pigment or dye, the carrier and the additive composition, the pigment or dye super constant evenly load attached to the resin and the aggregates can be called pigment concentrate (PigmentConcentration), so his tinting above pigment itself. Two, advantages The use of color masterbatch has the following advantages: 1. make the paint in process better dispersion. Color is the extraordinary amount of pigment uniformly loaded and attached to the resin prepared aggregates. To be on the pigment refining masterbatch production process, in order to improve the dispersion and tinting pigment. The carrier and the plastic masterbatch products for the same variety, with good matching, heating and melting of pigment particles can be well dispersed in plastic products. 2., it helps maintain the chemical stability of pigments. The direct use of pigment, the pigment in the process of storage and use in direct contact with the air, water, and other phenomena occur oxide pigments can, and fineness of the queen mother, because the pigment and resin carrier air, water separation, can make the paint quality unchanged for a long time. 3. ensure the stability of the color of the product. Masterbatch particles and resin particles are similar, more convenient and accurate in its measurement, mixing does not adhere to the container, and the resin mixed evenly, which can ensure the amount of stability, so as to ensure the stability of the color of the product. 4. protect the health of operators. Pigment is generally powder, add and mix easily flying, inhaled by the human body will affect the health of the operator. 5. keep the environment c
