Plastics coloring is mainly inorganic and organic pigments, it is required to have a high degree of color strength and brilliant; good transparency or hiding, dispersion, weather resistance, thermal stability, chemical stability, electrical function, environmental performance. Coloring size. Coloring power directly determines the amount of colorant generally decrease with increasing particle size of the colorant, organic pigments inorganic pigments color strength higher than many anti-caking fertilizer manufacturers colorants, when a color pigment and a white pigment, when used fertilizer anti-caking colorants companies, coloring power can be significantly improved, and now organic pigments and ultrafine particles are widely used and developed. Dispersibility. Generally inorganic pigment light stability better fertilizer anti-caking colorants, organic colorants, phthalocyanine-based, quinacridone-based, dioxazine, isoindolinone ketones and other organic pigment is excellent in light resistance, It can be comparable with inorganic pigments; anthraquinone and water chestnut ketone dyes also have good lightfastness. Migration resistance. Migration colorants are mainly three types, 1) solvent extraction, that water and organic solvents bleeding; 2) contacting anti-caking colorant migration fertilizer sales, causing pollution of adjacent objects; 3) surface blooming, mainly due to the coloring agent in the polymer during thermal processing of greater solubility, and solubility at room temperature is small, and therefore cause crystallization gradually. Inorganic pigments are generally non-homogeneous dispersion in the polymer, no blooming, and organic pigments in the polymer and other organic matter have different degrees of solubility, more prone to migration.
