Silica brick HI type
- Description
-
The main components of the H1 type of silicon brick are silicon dioxide (Si02) and aluminum oxide (AI203), which have high refractoriness, load softening temperature, thermal shock resistance and slag erosion resistance. At the same time, its volume density is small, the thermal conductivity is low, and the thermal expansion coefficient is also small, which makes the silicone brick H1 type has excellent thermal shock resistance and corrosion resistance at high temperatures.
Silica brick H1 type in the preparation process, through reasonable ingredients, molding and firing system, so that it has excellent performance and stable structure. In addition, the silica brick H1 type also has good thermal shock resistance, corrosion resistance and wear resistance, which can meet the requirements of high temperature equipment for refractory materials. In general, the silica brick H1 type is a high-grade refractory material with excellent performance, which is suitable for the lining of high-temperature equipment and has a wide range of application prospects.
