The difference between organic dyes and inorganic dyes
Organic pigments and inorganic pigments are two kinds of coloring pigments that we often come into contact with. We mainly talk about the difference between them and what is the difference between the two pigments.
Difference
Organic pigments are colored organic compounds, which are also divided into two categories: natural and synthetic. Now commonly used is synthetic organic pigments, organic pigment varieties.
Organic pigments, basically all kinds of chromatographic colors are bright and bright, much brighter than the color of inorganic pigments, and higher than the coloring power of inorganic pigments. Most organic pigments have excellent chemical resistance and stability, and have excellent acid resistance, alkali resistance, oil resistance and other properties, but the temperature resistance of organic pigments does not exceed 300 degrees.
Inorganic pigments are colored metal oxides, or some metal insoluble metal salts, inorganic pigments are divided into natural inorganic pigments and artificial inorganic pigments, natural inorganic pigments are mineral pigments.
Organic pigments can be divided into monoazo, bisazo, lakes, phthalocyanine or fused ring pigments and other categories.
Inorganic pigments are mainly carbon black and iron, titanium, barium, zinc, cadmium, lead and other metal oxides or salts.
Organic pigments have diverse structures, complete chromatography, and bright colors, but the products are light, weather, and solvent resistance!
Inorganic pigments have the characteristics of light resistance, weather resistance, high temperature resistance, solvent resistance, strong hiding power, etc., but the chromatography is not very complete, relative to organic pigments, inorganic pigments are not so fresh!
Organic pigments are used more in plastics, rubber, inks, pastes, paints, coatings and other related applications, while inorganic pigments are widely used in some building materials, enamel, ceramics, glass, and outdoor coatings.
