1)Production Introduction precipiated/light Calcium Carbonate selects high purity limestone as raw material, is made through process of calcining, chemical reaction, reselection, dehydration, drying and depolymerization. It is adopted the technics of particular multi-selection and secondary depolymerization. It is pure and stable filler whose bulk density is small. 2) Product Specification Product name Index Type Item High White Light Calcium Carbonate SN****0 CaCO3 % ≥ *9 PH (*0% Soliquid) 9.***0.5 Volatile matter under **5℃, % ≤ 0.*0 Insoluble substance in hydrochloric acid% ≤ 0.*0 precipitated volume , ml/g ≥ 2.4 Average Grain, μm ≤ 4.0 Fe, % ≤ 0.*0 Mn, % ≤ 0.**8 sieve residue :**5um test sieve % ≤ *5 um test sieve % ≤ 0. **0 0.*0 Whiteness(R**7), % ≥ *4 Note:We can provide standard products in different whiteness and purity according to use of customers by conferring
