mica
Mica particles (chips) in diameter and the thickness ratio (radius to thickness ratio) to achieve 80-120 times, the wafer thickness is only about tens nm to 100 nm. The unique sheet structure, for the flake paint, can be used as physical shield, prevent the sunlight UV from the destruction on the paint film, thicken corrosion proofing layer, restrain the antisepsis permeate, reduce the relict stress in the lining. In the building's exterior paint applications, in addition to improving the mechanical properties of coatings, can also improve the coating anti-aging, anti-UV properties, prevent cracking, delay chalking, along with the pigment particles can easily access to flaky mineral’s lattice layer, can maintain long-term paint color does not fade.
the application fields of mica powder:
improve the insulating properties of plastic products: Mica has a very high resistance, itself a high-performance insulating materials. Using mica to improve the insulation properties of materials is well known technology. For manufacture of high insulation plastic products, they may consider functional fillers wet ground mica. As noted above, the high iron content of the mica insulation lower, should be avoided. Of dry mica does not wash mine, a high iron content is generally not suitable for using such mica.
