Refractory mortar is composed of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder for preparing refractory mud. Ordinary refractory mud made of refractory clinker powder plus an appropriate amount of plastic clay as a binder and plasticizer has low strength at room temperature, and it has higher strength when it forms a ceramic bond at high temperature. The chemically bonded refractory mud, which uses hydraulic, air-hardening or thermosetting bonding materials as a bonding agent, produces a certain chemical reaction and hardens before the temperature is lower than the formation of ceramic bonding.
Refractory mortar is mainly used in the following aspects:
1. Masonry and maintenance of high-temperature furnaces, kilns and heat treatment equipment: refractories mortar has good high temperature resistance, and can be used for masonry and maintenance of various high-temperature furnaces, kilns and heat treatment equipment.
2. Filling of joints and cracks in industrial furnaces: Refractory mortar can effectively fill and seal joints and cracks in industrial furnaces, improving the sealing performance and thermal efficiency of the furnace body.
3. Heat preservation and heat insulation of high-temperature equipment: refractory mud has good heat preservation and heat insulation properties, and can be used as heat preservation and heat insulation materials for high-temperature equipment.
4. Maintenance of high-temperature pipelines and equipment: It can be used for maintenance of high-temperature pipelines, furnaces, furnace doors and other equipment to improve the service life of equipment.
5. Foundry industry: Refractory mortar can be used in the manufacture and maintenance of gates, slideways, sand boxes and other components in the foundry industry.
6. Glass, ceramics, cement and other industries: refractories mud can be used for masonry and maintenance of high-temperature equipment and production lines in glass, ceramics, cement and other industries
7. Chemical industry, metallurgy and other industries: The refractory materials can be used in the repair and maintenance of reactors, furnaces, furnace doors and other high-temperature equipment in chemical and metallurgical industries.
