Active calcium carbonate as high-grade high amount of filler filler, widely used in rubber, plastics, plastic steel windows and doors, high-grade paint, tubes, tires, shoe soles, polyethylene blown film, sealing strip, glass steel products, cable wrapping cloth, paper, building materials, printing ink, daily chemical, food additives and other industries. Active calcium carbonate was used as base material, and the surface of inorganic powder was modified by multi functional surface active agent and compound type high efficiency processing aid. The modification of calcium carbonate powder, formed on the surface of a special cladding structure, can significantly improve the dispersibility and compatibility of the polyolefin polymer matrix, and can produce interfacial interaction with polymer matrix, thus improving the products of impact strength is a kind of excellent performance of incremental type filling agent.
Active calcium carbonate features: features: (1) appearance: white powder, non-toxic, tasteless, no stimulation, not burning, not burst, refractive index is low, easy coloring, insoluble in water, stable properties in the air. (2) the product after activation treatment, changes in molecular structure, uniform particle size distribution, showed strong hydrophobicity. (3) has the characteristics of high whiteness, good fluidity, good gloss, uniform dispersion, large amount of filling etc.. And has excellent lubrication, mobility, dispersion and organic. (4) with rubber and plastic molecular affinity is strong, filling amount can fill more than ordinary calcium carbonate 2-5 times to several times, comprehensive production cost is significantly reduced. (5) oil absorption value of low, high whiteness and extension of high and super metal strip of the unique and significant lubrication effect can improve the brightness of the surface of the product, wear and impact strength. (6) can reduce wear degree of mechanical processing, improve product processing technology, improve product performance, with better reinforcing effect. (7) the product application in the advanced coating, improve the solid filling quantity, reducing viscosity, while giving coating wear resistance, corrosion resistance, reduce the baking temperature, baking time is shortened, improve product quality, reduce production costs, with obvious economic benefits.
