Quality Control Points of Mica Powder in Mica Insulation Material

May. 08, 2018

The use of electrical insulation materials is an important direction for China Mica Powder applications. Mica insulation needs a large enough area during use, with the exhaustion of large-scale mica resources. Sheet-like insulating materials prepared by crushing mica through appropriate processing methods have become the mainstream of mica insulation. Mica scale removal, optimum particle size composition control, surface modification, etc., have become important tasks for improving the quality of Mica Flakes and improving the performance of mica insulating materials.

The traditional way of preparing mica insulating materials is as follows: mica is prepared after mica pulverization, and mica paper is formed into mica plates with certain strength under the action of reinforcing materials such as epoxy resin, silicone resin, glass fiber, polyamide film, etc. Mica tape and other insulating materials.
