Is the production of heavy-duty glass flake coatings, pearlescent pigments and plastics indispensable raw material, used in the field of preservation, can significantly improve the corrosion resistance of coatings to extend the life of the object; used to make pearl pigments, pearlescent gloss glass flake pigments far better than natural mica, synthetic mica pearlescent pigment production, and both anti-corrosion, anti-ultraviolet radiation function; to the field of plastic, to increase the strength of the plastic products, to prevent thermal deformation of precision parts made of thermoplastic plastics, improve its dimensional stability. 1, a glass flake prevents water vapor and solvent on the substrate material chemical erosion. The extent of the substrate or coating with chemical resistance of the glass material of choice varies, the glass flakes by C- glass composition having excellent resistance to chemical durability. 2, the relative and steel, cement base material larger stretching coefficient, so in the case of thermal shock cracking, and the resin layer tends to fall off, and the glass flakes can commission a thermally stable layer, thus preventing the cleavage of the substrate and flaking. 3, good heat resistance. Glass flake lining of the use of its heat resistance than similar resin coating can improve 20-40 ℃, so commonly used in oil pipelines, water pipelines, heat-resistant chemical equipment and the like. 4, the thermal expansion coefficient. 5, the coating containing glass flakes harder than without glass flake epoxy or polyester resin layer, and therefore have a higher resistance to surface wear properties. 6, good compatibility properties, can be composed of a variety of anti-corrosion coatings and resins.
