Description:
This diatomite insulating bricks are made of high diatomite, bonding with other porous materials. Produced by our licensed technology, shaping by casting, sintering at high temperature then cutting and polishing to the demand sizes, the strength and insulating property are obviously improved.
► Application:
Diatomite insulating bricks can be used in reduction cell and hot blast pipe of various thermal equipment, which placed in the high requirement on heat-insulating.
