Second, the pigment is Pigment dyes that are generally different from the dye can be dissolved in water or a solvent, and the pigment is generally insoluble in water. Dye mainly used for textile dyeing, but this distinction is not very clear, masterbatch, because some dyes may be insoluble in water, but also paint pigments and liquid color printing for textiles. The chemical structure of organic pigments with organic dyes are similar, it is often regarded as a branch of the dye. Pigments are classified from the chemical composition, can be divided into inorganic pigments and organic pigments into two categories, its origin can be divided into natural pigments and synthetic pigments. Natural sources of pigments mineral cinnabar, red clay, realgar, malachite green, heavy calcium carbonate, wollastonite, talc, mica, kaolin, biological as from animal sources cochineal red, natural fish phosphors etc. as well as from Garcinia plant Alizarin red, indigo and so on. Synthesized by synthetic pigment, such as titanium dioxide, zinc white, barium, lead, chrome yellow, iron blue, iron red, red lead and other inorganic pigments, and scarlet, azo yellow, phthalocyanine blue, quinacridone organic pigments. Pigment functions can be divided into anti-rust paint, magnetic paint, luminous paint, pearlescent pigments, conductive pigments. In color classification is convenient and practical way, the pigment can be divided into white, yellow, red, blue, green, brown, purple, black, etc., without regard to its origin or chemical composition. l coloring basic concept: the color of objects is through the reflection of light, Pazhou masterbatch, refraction and transmission and generation. When the light is directed to colored plastic products, most of the light reflected from the object surface, bring luster feeling. The rest of the light is refracted and transmitted into the plastic, when light encounters pigment particles, will produce reflection, Guangdong masterbatch again, refraction and transmission. The principle of light reflection color: when the light shines on the yellow pigment, Hebei masterbatch, the reflected light is absorbed by a yellow pigment its complementary color * - blue, reflecting the yellow light. When light shines on a blue pigment, the yellow light is absorbed, reflected blue light. When the yellow light has passed, when the blue pigment, purple and blue light will be absorbed, only blue-green, green, green, yellow, orange and red light pass, then through the blue paint, yellow, orange, red colored light is absorbed. The last remaining blue-green, green and yellow-green light is reflected out. Pazhou masterbatch, masterbatch, may Lyle plastic (view) may be provided by the Texas Plastic Co., Lyle.
