ceramic foundry sand

Product Description

ceramic foundry sand is a high heat resistance, low thermal expansion, and spherical artificial casting sand obtained by spray treatment of a high oxidizing raw material in a molten state to recrystallize. Dense structure, grain shape is very spherical, smooth surface and small surface area. With high temperature, good permeability, collapsibility, acid and alkali resistance, low broken rate, cost-effective due to chromite sand, zircon sand, for the casting manufacturers to improve the quality of casting, reduce production costs and reduce environmental pollutiona simple and effective way.

Characteristics:

1.Thermal expansion coefficient is small

2.Sand for the spherical, good liquidity, easy to ramming, and good ventilation

3.Smooth surface, dense structure, making the adhesive can be evenly covered

4.Reuse regeneration performance, cost-effective

5.High refractoriness, easy to collapse

6.Thermal conductivity, good stability, no cracking

Application:

Water glass sand, resin sand, precision casting and copper, aluminum pieces of polishing clean
