The gunning castable possesses the following characteristics:

1. Good Adhesion: It can firmly adhere to the surface of the object being gunned, and is not easy to fall off. This ensures a strong bonding force between the gunned layer and the substrate, effectively repairing the damaged part.

2. High Fluidity: During the gunning process, the gunning castable can smoothly pass through equipment such as spray guns and be evenly sprayed onto the target surface, ensuring the flatness and uniformity of the gunned layer.

3. Rapid Setting and Hardening: After gunning, it can set and harden within a relatively short time, quickly forming a gunned layer with a certain strength, so as to restore the normal use of the equipment as soon as possible and reduce the downtime.

4. High Temperature Resistance: It has good high-temperature resistance properties, and can withstand the test of high-temperature environments. It remains structurally stable at high temperatures and is not prone to deformation, melting, or spalling, making it suitable for the repair of various high-temperature industrial kilns and other equipment.

5. Strong Thermal Shock Resistance: It can resist sudden changes in temperature without cracking or spalling, and can maintain good performance under thermal shock conditions, ensuring the reliability of the gunned layer during the operation of the equipment.

6. Good Abrasion Resistance: It has high hardness and good abrasion resistance, and can withstand the scouring and abrasion of high-temperature gas flows, furnace slag, materials, etc., prolonging the service life of the repaired equipment.

7. Excellent Corrosion Resistance: It has a certain resistance to some chemical substances, and can prevent the erosion of acidic or alkaline substances in furnace slag, flue gas, etc. on the gunned layer, maintaining the integrity and performance of the gunned layer.

8. Good Plasticity: Before hardening, the gunning castable has a certain degree of plasticity, and can be adjusted according to the shape and surface condition of the gunned object, better fitting complex surfaces and improving the repair effect.
