Brief description of refractory plastics
The main components of refractory plastics are specific types of resins and fillers that, after special processing, can withstand high temperatures while maintaining excellent mechanical strength and stability. These materials can usually withstand temperatures exceeding 1000 degrees Celsius without significant physical deformation or chemical degradation.
The main components of refractory plastics include aggregates such as high-alumina clinker, corundum, mullite and silicon carbide. The binder is usually raw clay or chemical composites, and admixtures may include expansive materials such as kyanite powder, dll.. 65. Depending on the material, refractory plastics can be divided into clay, high-alumina, corundum, silicon, magnesium, chromium and silicon carbide.
