When choosing refractory materials, we must first pay attention to the quality of refractory materials, so how to judge the quality of refractory materials? Judging the quality of refractory materials can be evaluated from the following aspects:
1. Physical properties: including compressive strength, wear resistance, impact resistance, etc. The performance of refractory materials under different physical conditions can be evaluated by laboratory tests or by referring to relevant standards.
2. Fire resistance: mainly including high temperature resistance, corrosion resistance and thermal shock resistance. Refractory materials should be able to withstand the challenges of thermal cycling at high temperatures, chemical attack and thermal shock without significant cracking, debonding or failure.
3. Composition and structure: The composition and structure of refractory materials have a great influence on its performance. The composition should meet the design requirements, and the combination of materials should be firm to avoid problems such as cracks and pores.
4. Thermal conductivity: High-quality refractory materials should have low thermal conductivity to reduce energy loss and improve thermal efficiency of equipment.
5. Durability: The durability of a refractory material means its stability and life during long-term use. This can be assessed by practical application experience, the historical record of the refractory material, and the reputation of the supplier.
6. Supplier reputation and certification: select suppliers with good reputation and experience, and ensure that the selected refractory materials meet relevant standards and certification requirements, such as ISO 9001 quality management system certification, etc.
At the same time, on-site inspection, practical application test and communication with other users are also important means to evaluate the quality of refractory materials. Comprehensive consideration of the above factors can effectively judge the quality of refractory materials and select high-quality refractory materials suitable for specific application requirements.
