Characteristics of refractory cement
1. Good high temperature resistance: The main characteristic of refractory cement is that it can maintain stable performance in high temperature environment, and can usually withstand high temperature up to 1500℃.
2. Good chemical corrosion resistance: Since refractory cement contains a large amount of chemical components such as aluminum oxide and silicon oxide, it can resist the erosion of strong corrosive substances such as acids and alkalis.
3. High compressive strength: Refractory cement has high compressive strength and can withstand great pressure, so it is widely used in construction, metallurgy and other industries.
4. Refractory cement has strong plasticity: Refractory cement has good processing performance and can be made into refractory products of various shapes and sizes through different processing techniques.
