The roles of chromite flour in mineral pigments
Chromite flour plays a vital role in mineral pigments, which is mainly reflected in the following aspects:
Ⅰ. As a green mineral pigment
The main component of chromite flour is chromite, which contains chromium oxide, iron and magnesium. Among them, trivalent chromium (Cr2O3) is an important green mineral pigment. Natural chromite flour can be used directly as a green pigment without chemical synthesis, providing natural green for painting, handicrafts, antiques, cultural relics restoration and other fields.
Ⅱ. Enhance the performance of pigments
1.Full color: chromite flourhas a bright green color. Adding it to the pigment can enhance the color fullness and brightness of the pigment, making the surface of the coated object more beautiful.
2.Strong weather resistance: The pigment made of chromite flour has good weather resistance, can resist the erosion of natural environment such as sunlight, wind and rain, and maintain the durability of color.
3.Heat resistance: chromite flourhas excellent heat resistance and can withstand high temperature environment without discoloration. Therefore, it is suitable for objects that need to be subjected to high temperature treatment, such as ceramics, glass, etc.
Ⅲ. Improve coating performance
Adding an appropriate amount of chromite flour to the coating can enhance the color, weather resistance and wear resistance of the coating. The high hardness and wear resistance of chromite flour can increase the hardness and scratch resistance of the coating and improve the service life of the coating. At the same time, its good chemical stability also enables the coating to resist the erosion of various chemical substances.
Ⅳ. Wide application areas
1.Ceramic industry: As an additive for green ceramic glaze, it is used to produce various ceramic products that require green coloring.
2.Glass industry: As a green colorant for glass containers, such as green or olive beer bottles, red wine bottles, etc.
3.Ink and pigment industry: Ultrafine chromite flourcan be used to produce printing inks to improve the color and printing effect of inks.
4.Foundry industry: Used for coatings in key parts of sand casting to prevent defects such as sticking sand, cracks, and pores.
5.Wear-resistant coating: Made into wear-resistant coatings, used for linings of mechanical parts, building materials and chemical equipment to enhance wear and corrosion resistance.
