Silica Insulation Brick
Silica insulation brick has excellent fire resistance and the load softening temperature is as high as 1620℃. Therefore, we can use it for a long time under high temperature conditions (1500℃~1550℃) without contact with slag.
- SiO2(≥): 91%
- Bulk Density: 1.00g/cm3 – 1.20g/cm3
- Refractoriness Underload: 1480℃ – 1560℃
- Cold Crushing Strength: 2.0MPa – 5.0MPa
The Advantage of Silica Insulation Brick
Stable Structure
Kerui silica insulation fire brick can maintain shape and strength for a long time in high temperature environments. Its unique material composition and manufacturing process enable it to withstand stresses caused by thermal expansion and contraction. So, this reduces structural deformation and damage caused by temperature changes.
Not Easily Cracking
The thermal insulation silica brick has excellent crack resistance. It can effectively prevent the occurrence and expansion of cracks. Its structural design gives it high tensile strength and impact resistance. Therefore, silica insulation bricks can withstand the influence of external forces and thermal stress and increase their service life.
Energy Saving
Using silica insulation brick can effectively insulate, reduce heat loss and improve energy efficiency. It has low thermal conductivity and excellent thermal insulation properties. So, it can prevent heat conduction and radiation and provide an excellent thermal insulation effect. That is to say, using Kerui insulation brick can save production costs.
Protect Industrial Equipment
We also widely use light weight silica brick to protect industrial equipment from damage caused by high temperatures, corrosion and wear. It has excellent fire resistance and chemical corrosion resistance. In other words, light weight silica brick can effectively isolate and protect equipment surfaces and reduce maintenance costs.
