RS group production of corundum mullite plastic for sale is made with reasonable particle size gradation of corundum, mullite refractory aggregate, powder and plastic excellent plasticity clay and alpha alumina micro powder and proper efficient composite bonding agent, plasticizer, water after fully mixing system, and for a long time to maintain high plasticity of an amorphous high-grade refractory materials.
Characteristics Of Corundum Mullite Plastic
1.Small volume density, belonging to neutral refractory with high plasticity.
2.Strong viscoplastic, soft and plastic, strong adhesion at room temperature, suitable for difficult engineering parts.
3.Micro-expansion at high temperature, high degree of consolidation after drying, shock resistance, not easy to crack, better than traditional concrete.
4.Service temperature: 1100-1300℃.
5.Stable and reliable quality, non-toxic, non-corrosive, easy to use, easy to preserve.
