SEPPE Ceramic Sand Used for Foundry and Casting:


1. Artificial bauxite sand has small thermal expansion coefficient, good performance as zircon sand;


2. Spherical appearance with good liquidity and better ventilation;


3. Smooth surface with compact structure, uniformly covered of adhesive;


4. It is a neutral materials that can be used with acids, bases or binders;


5. Price is only 25-50% of chromite sand and zircon sand. Meanwhile, sand is spherical with small surface area, so the added amount of the resin can be reduced by 30-50% and the added amount of sodium silicate can be 4%; and reducing casting defects caused by the binder and improving the output of castings;


7. High refractoriness, easy collapsing;


8. The fire resistance of mullite in the bauxite sand is much better than other sintered products;


9. Good thermal conductivity and stability without cracks;


10. Wide applications. Used for polishing and cleaning of resin sand, sodium silicate sand, clay sand, EPC, investment casting, copper and aluminum.
