Casting sand like jewelry

Casting sand like jewelry Bulk density: 1.95 to 2.05(g/cm3) Angle factor; <1.1 Shape: ball-shaped Size: 20 to 200 mesh

Ceramic Sand features: 

1, the thermal expansion coefficient is small, performance can be comparable with the zircon sand, sand with its preparation, no expansion of casting defects.

2, sand for the ball, good fluidity, easy  and good ventilation

3, smooth surface, compact structure, making the binder cover evenly

4, ceramic materials, neutral sand, acid, alkali binder apply

5, re-use regeneration performance, cost-effective

6, high refractoriness, easy collapsibility

  

7, thermal conductivity, good stability, do not crack

Application range

the application of a wide range of silicate sand, resin sand casting and brass, polished aluminum parts cleaning
