Purpose: Used in conjunction with honeycomb structures to protect and extend the service life of thermal storage systems.
Detailed Introduction
Purpose: Used in conjunction with honeycomb structures to protect and extend the service life of thermal storage systems.
Features: Selection of corundum fused mullite, corundum synthetic mullite, sintered mullite, etc; The material, after casting and molding, is baked and high-temperature fired. The external dimensions and structure can be produced according to user requirements, and it has the characteristics of good thermal shock stability, high softening point, strong chemical resistance, and good heat shock resistance.
