The mineral powder surface modification is the result of the development of modern technology and new material and 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 surface modification effect.
Obviously decreasing the viscosity of the filled polymer system and increasing the filling content.
Improving the product surface luster and increasing dimensional stability.
Enhancing the product mechanical properties such as tensile strength, impact strength, flexibility and yield strength etc.
