Organic Pigment For Plastic Coloring characteristics

Carbon black we all know that it can be used to make Chinese ink, ink, paint, etc., in our eyes of organic pigment manufacturers, it can also be used to color the plastic, many people still have some doubts about this, today, organic Pigment manufacturers for everyone to lift this question, so that we learn more knowledge.

Organic pigment manufacturers tell you that pigment carbon black can generally be better to color the plastic, according to the coloring properties or physical and chemical properties of the choice of pigment carbon black, coloring with the choice of carbon black varieties are basically with the finished product must reach the black Depending on. With very fine pigment carbon black can be done to achieve a particularly high degree of black coloring; PE garbage bags, plastic bags, cable materials and other products only moderate level of blackness, you can use a smaller surface area, the higher structure of carbon black varieties ; Plastic color, the carbon black weighing and ingredients when the slight error, will lead to significant color, therefore, should adopt a larger particle size, poor color strength of low pigment carbon black, so the amount of carbon black can be slightly Large, weighing error is relatively small, and there is a better dispersion, the advantages of lower prices.

Organic pigment manufacturers for gray plastic, the use of fine pigmented carbon black often show brown phase gray, and the use of coarse particles of carbon black can produce blue-gray. Compared with other organic pigments, carbon black in addition to more difficult to disperse, the other properties are better. Scientific amount of carbon black with the amount, can provide better anti-static or conductive. Carbon black is basically non-toxic, but more easy to fly and pollution, so often in the form of masterbatch for the plastic industry to use, in the elimination of pollution at the same time also improve the dispersion of carbon black in plastic. Carbon black as a plastic pigment, commonly used formulations are powder and granular. Granular carbon black flying less, but the dispersion is more difficult, so in the use of plastic coloring carbon black.

See here, now we should believe that organic pigments manufacturers said carbon black can be colored in the plastic bar.

Tinting, dispersibility, processability and heat resistance are the main indicators that determine the performance of organic pigments in plastics. Thus, we have passed a series of experiments on indicators such as color strength, dispersibility, processability and heat resistance of organic pigments The preliminary analysis of the determination and characterization of the organic pigments was carried out. The domestic varieties of organic pigments were compared and analyzed, and then the domestic pigment was compared with the foreign similar products. The data were analyzed and analyzed systematically. Paintability data for pigments.

For example, the heat resistance of the pigment refers to the characteristics of the pigment itself and the color change after the coloring of the plastic in the case of heat. The main factors that affect the heat resistance of the pigment are to remove the chemical structure, molecular polarity, molecular weight and so on. In the pigment production process The size of the reactor, the length of the pipeline, whether the same color production lines, which are directly affecting the organic pigments, such as resistance to temperature migration and other properties.
