20-40mesh ceramic foundry sand price

Ceramic Foundry sand is made of high quality bauxite, which has been remelted and then blown into ball shape. Ceramic Foundry sand is a new casting material with high surface finish and good air permeability.

Grit size available: 12-20,16-20,16-30,20-40,30-50,40-60,40-70,70-100,70-140 etc

The performance characteristics

1. Fire resistance; Composition is stable, not easy to produce chemical changes, it can reach 1900 ℃ refractoriness.

2. Liquidity; For spherical particles, its mobility is very good, modeling easy compact, and can maintain good air permeability.

3. Air permeability; The permeability of molding sand mainly depends on the size, size distribution, size and type of binder.

[Advantage of ceramite foundry sand ]:

1. Round solid ball shape, saving binder addition;

2. High refractoriness and easy collapse;

3. Good air permeability and excellent dispersibility;

4. Lower thermal expansion rate and thermal conductivity;

5. Standard particle sizes;

6. Easily reclaimed and lower breakage rate during dry crushing;

7. To reduce pollution and protect environment.

8. Recycling performance is good, cost - effective

9. Wide range of applications: water glass sand, resin sand, precision casting, etc.

1. Ceramic Foundry sand is widely used in resin sand (furan resin, phenolic resin), water glass sand (organic fat, CO2 hardening), and coated sand.

2, Ceramic Foundry sand is suitable for all kinds of metal castings such as: carbon steel, alloy steel (high manganese steel, high chromium iron), cast iron, cast copper.

3, Ceramic Foundry sand is a non-quartz type of artificial sand, suitable for various casting methods such as: V method, VRH, lost foam mold, investment mold, general sand mold (clay sand, sodium silicate +CO2 hardening), resin sand.

4, orb sand are suitable for all kinds of adhesive, all kinds of metal materials of casting production.

5. Ceramic Foundry sand is suitable for polishing and cleaning of lost foam mold, coated sand.

6. Reuse performance; By reducing the amount of waste sand and increasing the amount of effective recycled sand, the loss of molding sand is greatly reduced.
