Common in daily life, such as clothing dyes, painting pigments, etc., generally use organic pigments, which have bright colors, strong tinting strength and complete chromatograms, but if they are used in enamel, ceramics, glass or some application fields with special requirements , Inorganic pigments are usually used because inorganic pigments have good physical and chemical properties, high thermal stability and excellent mechanical strength. For major manufacturers, inorganic pigments are low in price and simple in process. The best choice.

So where exactly can inorganic pigments be used? Pick up a few simple and commonly used examples to introduce:

1. The application of inorganic pigments in enamel

Due to the particularity of the production process of enamel products, there are requirements for the high temperature resistance and chemical stability of inorganic pigments. At the same time, they also require pure chromaticity, good chromaticity reproducibility, strong tinting strength, fine particle size, Easy to disperse etc.

There are many colors of inorganic pigments, such as cadmium red, chrome green, cobalt black, cobalt blue, etc. If the basic color can meet the requirements of enamel manufacturers, then it is good to directly process the natural color of inorganic pigments.

If it is a manufacturer who has higher requirements for color, then you need to choose a well-prepared enamel pigment, such as a semi-opaque frit with opaque cover coat - neutral white, full opaque frit - antimony white, etc., or Match different pigments with each other, and match different colors to adjust the colors required by enamel manufacturers, such as gray (black + white), orange red (cadmium red + cadmium yellow) and so on.

 

Second, the application of inorganic pigments in ceramics

If it is a low-temperature ceramic with a firing temperature of 900 °C, it is good to use enamel pigments directly. For high-temperature ceramics with a temperature of 1280~1350 °C, you need to use encapsulated pigments.

Third, the application of inorganic pigments in coatings

Inorganic pigments can be used as oil-based high temperature coatings, such as resin pigments, fillers (mica powder, talc powder, glass powder), additives (dispersants), etc., or as high temperature powder pigments.

Fourth, other applications of inorganic pigments

Inorganic pigments can also be used in the production of colored glass and high temperature inks.

 

In addition to the above common fields, if the manufacturer finds that there are other pigments that need to be used, but organic pigments cannot meet their requirements, inorganic pigments can be used.
