Although mica is a natural element found on the earth’s crust, it takes a long procedure of creating a variety of mica products. For instance, mica powder and sheets come from the same source mica, but they are created through different processing. Mica powder is composed of tiny particles that are obtained from mica mineral ores. From food ingredients to cosmetics, final products are available in different forms. Here, we discuss the process of mica powder and its applications in different industrial sectors.
How mica powder is process
Mica powders are made from natural mica found coated with other minerals such as iron oxide and tin oxide. They are transformed into coarse, medium, and fine grades of flakes and powder by the process of pulverization. Mica powder suppliers use sophisticated tools to crush and sieve mica flakes while mica power is obtained by grinding the flakes to a size of 2 to 30 mesh. Before initiating the process in a mica plant, the ingredient is transported from its main source, mica mine somewhere.
These powders are then distributed to different industrial sectors. Manufacturing units use these products to create items for end-users around the world. Each item may require a specific quantity of mica powder depending on the total finished product weight.
Applications of mica powder
High-quality raw materials are used for manufacturing mica powder. The standard grades of mica flakes are crushed to 60 mesh and 100 mesh. They have various applications in different processing units, including:
Paint
Paint companies use mica powder as a pigment that helps enhance the property of suspension. It reduces chalking, prevents shearing of the paint film, increases the ability to resist water or extreme weather, and brightens the tone of color.
Welding
Steel factories use ground mica to weld electrodes in steel minerals. The coating of mica on the steel provides a good seal at the fusion zone. It also helps resist the heat and atmospheric oxidations that can cause corrosion on the steel.
Oil drilling
The oil and gas refinery industry uses mica as an agent to optimize the process of drilling in the mud. The ground mica also prevents the detrition around the porous section of the drill hole.
Insulation
Mica has been a great choice of making an insulation system in industrial and domestic sectors. Dry mica flakes for insulation materials are used as in automotive brake linings and clutch plates to reduce noise and vibration. The additive also helps in maintaining the temperature of an enclosed environment by blocking heat, chemical, and UV radiation.
