Refractory joint materials play an important role in various industrial fields, mainly used in the following aspects:
1. Sealing and anti-leakage: Refractory joint materials can fill and seal the joints or cracks between refractory components to prevent the leakage or penetration of media (such as gas, liquid). They are usually used in the joints of high-temperature equipment, kilns, furnaces, piping systems, etc., to ensure the sealing performance of the system.
2. Buffering of thermal expansion and thermal shock: Refractory joint materials have certain flexibility and deformation ability, which can buffer the stress concentration between components caused by thermal expansion and thermal shock. They are able to withstand thermal stress caused by temperature differences during thermal cycling, providing mechanical strength and stability.
3. Maintenance and repair of refractory components: Refractory joint materials can be used for maintenance and repair of refractory components. Over time and as conditions of use change, refractory components may break, crack or wear away. Refractory joint materials can be used to repair and strengthen these components to extend their service life.
4. Temperature isolation and thermal blocking: Refractory joint materials have low thermal conductivity and can be used to achieve temperature isolation and thermal blocking in high temperature equipment. They reduce heat transfer and the formation of thermal bridges, improving the thermal efficiency and energy utilization of the system.
5. Chemical corrosion resistance: Some refractory joint materials also have good chemical corrosion resistance and can withstand the erosion of corrosive media such as acid and alkali. They can be used in chemical plants, battery manufacturing, oil refining and other fields to protect equipment from corrosion and damage from chemical media.
In short, refractory joint materials play the role of sealing, protection, maintenance and repair in high temperature environments, ensuring the safe operation of industrial equipment and systems, while improving the service life and performance of refractory components.
