Direct Jiangxi ceramic grade active wollastonite powder

Activity wollastonite powder I. Introduction Products using the new imported high active agent for surface treatment of ultrafine wollastonite powder particle surfaces were coated effective activation, the activation rate of the product can be up to 97%. Second, the product index Specifications are SiO2 content% ≥ 49 Fe (iron) content% ≤ 0.02 D97 (um) 10 particle Whiteness% ≥ 90 PH value 8.5 Mohs hardness of 6 Bulk density g / cm3 2.8 Melting point ° C 1550 CaO calcium oxide % ≥ 45 Appearance white powder silane coupling% ≥ 2 Note: You can produce different brightness according to customer demand, purity, fineness of active wollastonite powder. Third, the products are widely used in rubber, plastic, nylon and other polymer-based composite materials inorganic reinforcing filler. After treatment with the silane coupling agent wollastonite filled polycarbonate, elastic modulus is unfilled when the 3-fold, about 15% increase in strength, filled into polyethylene, which can improve the strength and electrical insulation properties, is filled to the polypropylene, as compared to unmodified wollastonite filler, filler content in the same conditions, significantly improved the tensile strength, bending strength, etc.
