Product Introduction
Refractory spray coating is divided into heavy spray coating and light spray coating. It is composed of 0-5m particle grading, chemical binder and admixture. It is an amorphous refractory material used for repairing the lining of thermal equipment by spraying construction method.
Product Advantage
Strong thermal adaptability
The characteristics of refractory spray coating are: low rebound rate, good high temperature performance, strong thermal adaptability.
No need to stop the furnace to cool down
When using spray coating to repair various industrial kilns, there is no need to stop the furnace to cool down.
Reduces production costs
It can be directly sprayed or repaired with a spray gun, which greatly shortens the repair time of the furnace lining and reduces production costs, with excellet wear-resistance and anti-spalling performance, strong and durable.
