Industrial background
The surface modification of mineral powder is the result of the development of modern technology and new material and it is widely used in various industries such as non-metal mineral filler and pigments like high molecular materials including plastics, rubber and adhesives etc., high polymer matrix composites, functional and coating materials and so on.
Heavy and light calcium carbonate, various kaolin, talcum, grammite, quartz powder, mica, white carbon black, titanium dioxide, zinc oxide, aluminum oxide, magnesium hydroxide, barium sulfate, glimmerton, pyrophyllite and tremolite etc. have good effect of surface modification.
Application performance
1. The viscosity of the filled polymer system is decreased obviously and the filling content is increased.
2. The product surface luster is improved and dimensional stability is increased.
3. The mechanical properties of finished product such as tensile strength, impact strength, flexibility and yield are enhanced.
