Calcined Kaolin Clay 1. It's produced with ultrafine grinding then high-tempreture calcined modified By introduced advanced equipments oversea. 2. It has many superior properties such as plasticity, cohesiveness, dispersity, insulativity, sinterability, Fire resistance, refractoriness, absorbability, weather resisitance, stable chemical property, 3. High light scattered power and good hiding power etc. 4. Widely used in lines of paints, printing ink, coatings, plastics, rubber, glass, electrical string And lines, powder paint, road marks etc. ITEM 325-800 mesh 1250-6000mesh 1.whiteness % 90±2 93±2 2. residue on sieve (325mesh) (by actual demand)% ≤0.1 ≤0.05 3.refractivity % 1.55 1.65 4.moisture % ≤0.6 ≤0.5 5.PH value of aqueous suspension 6.5-7.2 6.5-7.5 6.oil absorption (upon various fineness) g/100g 50±5 65±5 fineness can be ordered by special requested meshes:325,400,600,800,1250,2000,3000,6000 etc. CHEMICAL INDEX/INDICTOR SiO2 (%) Al2O3(%) Fe2O3(%) TiO2(%) CaO(%) MgO(%) K2O(%) Na2O(%) MnO(%) 52±2 45±2 ≤0.4 ≤1.0 ≤0.4 ≤0.2 ≤0.04 ≤0.1 ≤0.005
