Payment Method: T/T (I) Chemical Composition SiO2 62 -- 70% Al2O3 17 -- 23% Fe2O3 2.5 -- 5.3% Cao+Mgo 1 -- 2% K2O+Na2O 2 -- 3% (II) Refractoriness 1508℃- - 1545℃ (III) Colloid Index According to the sample specific test of colloid index of bentonite in the standard of No.JN438 “Clay Sample” issued by the 1st Ministry of Machine-Building Industry, the colloid index is 40%. (IV) Green Compression Strength According to the sample specific test of colloid index of bentonite in the standard of No.JN438 “Clay Sample” issued by the 1st Ministry of Machine-Building Industry, the green compression strength is ≥0.5kg/cm2 (IV) Granularity 300-800 mesh (VI) Others ① It is of high contents of K and Na, low contents of Ca and Mg. According to the experiment, add it as preparing activity sandsidy. As Na2CO3 is 2-3% of argil weight, it has the highest wet strength. It can save amount of Na2CO3. ②Crude ore of this product is earthy mineral, easy to crush and of fine granularity; due to low unit weight and large volume, as preparing molding sand, it is easily to spread powder argil evenly on the sand to increase wet strength of sand. In usage, please make experiment to master unit weight if weighing it by container instead of scale, otherwise, less argil affects the strength. ③ Swelling ratio ≥ 10 |
