Production method:
The advantages of zircon brick mainly include its excellent fire resistance, chemical stability, and specific physical properties. The main component of zircon brick is zircon, this material has the following significant advantages:
1. Excellent fire resistance: zircon brick maintains stable performance at high temperature, has a high load softening temperature, can work stably for a long time in high temperature environment, and is suitable for industrial application scenarios that need to withstand high temperature.
2. Good chemical stability: zircon brick insoluble in acid and alkali, this feature makes it show good stability in the chemical environment, can resist the erosion of various corrosive media, so as to extend the service life.
3. Specific physical properties: Zirconium brick has a low thermal expansion coefficient and thermal conductivity, which helps to maintain the structural stability of the material and reduce material deformation or cracking caused by temperature changes. In addition, the zircon brick has a high Mohs hardness, which enhances the wear resistance and compressive strength of the material.
4. Widely used: zircon brick because of its excellent performance, is widely used in metallurgy, glass, ceramics and other industries. For example, in the metallurgical industry, zircon bricks are used in the lining of steel barrels for masonry degassing and continuous casting. Their good corrosion resistance and thermal shock resistance make them become important materials in the metallurgical industry. In addition, the zircon brick is also used in the flame space of the glass furnace and the cover plate of the material channel, the pressure joint brick and other parts, the corrosion resistance of the glass alkali vapor is strong.
