The main characteristics and application range of molding sand powder (Qufu Longxiang Smelting Casting Accessories Co., LTD.)

Uniform particle size distribution, high purity, easy to disperse, higher than the surface, with high temperature resistance inert, high activity, belongs to activated alumina; Porosity; With high hardness, good dimensional stability, strong surface acidity and certain surface alkalinity, it is widely used as a new green chemical material such as catalyst and catalyst carrier.

It can be widely used in reinforcing and toughening various plastics, rubber, ceramics, refractory materials and other products, especially to improve the density, finish, cold and thermal fatigue, fracture toughness, creep resistance and wear resistance of polymer material products are particularly significant. Easily dispersed in solvent water; Solvent ethanol, propyl alcohol, propylene glycol, isopropyl alcohol, ethylene glycol monobutyl ether, acetone, butanone, benzene, xylene, without adding dispersant, stirring can be fully dispersed and uniform. In epoxy resins, plastics, etc., added use.
