Muscovite Mica High Temperature Resistance For Cosmetic Paint Coating

Mica includes Muscovite, Phlogopite, Biotite, Sericite, Synthetic mica, Calcined mica, Conductive mica and Color mica flakes.
Muscovite Mica, whose chemical formula is KAl2(AlSi3O10)(OH)2, is the most common mineral of the mica family. Global mica consumption is up to 1 million tons and 90% is Muscovite Mica. It has obvious layered structure and it is fairly light and relatively soft. Muscovite Mica is an important rock-forming mineral present in igneous,metamorphic, and sedimentary rocks. As a natural silica, Muscovite Mica is a very special functional filler due to its high lamellar structure and purity. Muscovite Mica is chemically inert, resistant to most acids and oxidation, insoluble in water and has a high temperature resistance. It also shows excellent electrical insulation performance.

Processing Technology

There are two manufacturing processes of mica powder: dry grinding and wet grinding. We have our own factories to produce these two products.

Dry ground mica powder is produced by physical grinding without changing any natural property of mica. We adopt total enclosed filling system to guarantee quality during the whole production process. In the screening process,we also employs proprietary equipment and technology to ensure uniform particle distribution and stable quality. As to its superior performance, dry ground Muscovite has been extensively used in production of various products, including fiber cement construction panels / wallboards, plastics, rubber, paint, coating, welding electrodes, oil drilling and brake pads.

● Dry ground process

Wet ground mica powder is produced from natural mica flakes through a series of processes, including cleaning, washing, purification, wet grinding, drying, screening and grading. The unique production process retains the sheet structure of mica , therefore wet ground mica is featured by large radius-thickness ratio, low sand and iron content, high purity, whiteness and glossiness. The unique property of wet ground mica makes it widely used in industries such as paint, coating production, rubber, plastics and ceramics. It is especially effective to improve product's electrical strength, rigidity, heat resistance and to reduce molding shrinkage and cost.

● Wet ground process

Certificate

Our factories have achieved ISO Certificate, 23 technologies have obtained national patents.
