The origin of paint pigment-江苏鼎秀-五组新星队-黄苏皖

Analysis of the origin of paint pigments:

The paint pigment makes the film present color, so that the film has the ability to cover the object to be coated, so as to play its decorative and protective role. Some pigments can also provide such properties as improving the mechanical properties of paint film, improving the durability of paint film, providing anti-corrosion, conductive, flame retardant and so on. Pigments can be divided into natural pigments and synthetic pigments according to their sources, inorganic pigments and organic pigments according to their chemical compositions, and coloring pigments, constitutional pigments and special pigments according to their functions in coatings

In the early days, vegetable oil was the main raw material of paint pigments, so it was called "paint pigments", such as the health and environmental protection of the original ecological ripe tung oil. Both the traditional coating products with natural materials as raw materials and the modern coating products with synthetic chemical products as raw materials belong to organic chemical polymer materials, and the film formed belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multifunctional engineering materials, which is an important industry in chemical industry

Because in a certain range of particle size, the finer the pigment is, the stronger its covering power and coloring power are, so that the main tone and brightness of the pigment are improved. The formation of aggregates is related to the precipitation conditions, such as initial concentration of reactants, pH value of solution, reaction temperature, reaction time and calcination temperature.
