Detailed Product Descript ion
fireclay refractory mortar
good bonding strength,high temperature resistant,erosion resistance,and ensure the whole performance
HNM fireclay refractory mortar
HNM refractory slurry we produced is used as the supplement products with HMQ and
HML series insulation bricks. The refractory slurry is confected by different grades of
fine powder and special bonding agents, it is a kind of air setting mortar served in wet
status. It is of good bonding strength, high temperature resistance, erosion resistance,
and the whole performance of the brickwork could be ensured.
