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
