Refractory joint materials are materials used to fill and seal joints or cracks between refractory components. It has the following main requirements:
1. High temperature resistance: Refractory joint materials need to be able to work stably for a long time in a high temperature environment. It should have a high melting point and high temperature resistance, and be able to withstand thermal cycling and thermal shock under extreme temperature conditions.
2. Corrosion resistance: Refractory joint materials must be able to resist aggressive media such as acids, alkalis, solvents, gases, etc. for specific industrial environments. It should not be eroded by these media and maintain the stability of its physical and chemical properties.
3. Dimensional stability: Refractory joint materials need to maintain good dimensional stability at high temperatures to avoid cracking, damage or falling off due to thermal expansion and contraction. It should be able to adapt to thermal expansion and contraction caused by temperature changes, and have certain flexibility and deformation ability.
4. Bonding performance: The refractory joint material should have good bonding performance, be able to be firmly bonded to the surface of the refractory component, and provide a reliable sealing effect. It should have good adhesion and adhesion to ensure the integrity of the seams.
5. Wear resistance: Refractory joint materials need to have a certain degree of wear resistance, able to resist wear and abrasion caused by mechanical vibration, particle impact or material flow.
6. Construction and Repairability: Fire-resistant joint materials should have good construction properties and be easy to fill, coat and repair. It should be able to harden or dry quickly so that the work process can be carried out smoothly.
7. Environmental friendliness: fire-resistant joint materials should meet environmental protection requirements, and do not contain substances harmful to human health or the environment, such as harmful heavy metals, organic solvents, etc.
These requirements can vary based on specific application needs and industry standards. When choosing fire-resistant joint materials, it is necessary to comprehensively consider the above requirements, and consult with suppliers or professionals according to specific conditions to ensure that the most suitable fire-resistant joint materials are selected.
