Карбонат кальция

Active Calcium Carbonate for Plastic's Characteristics: (1)Identical grain size, low oil absorption value (2)To enhance hardness, rigidity, size stability, fire-retardants, glossiness of products (3)To reduce the cost of products, to make products have good foamed effect. (4)In rigid plasticproducts, it can accelerate gelation, enhance cold impact strength, eliminate plate out, and improve surface gloss indexActivated Calcium Carbonate for PlasticCaCO3 content%≥98PH value(10% suspension)8-10Hydrochloric acid should not matter content %≤0.3Water content %≤0.3Specific Surface cm2/g ≤50000-55000Sedimentation Volume ml/g≥1.1-1.9Average particle size μm8Fe content %≤0.01Mn content%≤0.006Screenings: 125um test screening %≤0.545um test screening %---Whiteness %≥94Oil- Absorption (DOP)gml/100≤30Activation rate %≥99Appearance
