Excellent thermal shock stability, more than 30 cycles of water cooling at 1100 ℃, no dimensional changes, no cracks, no deformation of the product, and can be directly repaired without stopping the furnace

The thermal expansion rate is close to zero

Zero Expansion Silica Brick

Tuck stone    Hanging Brick

Hot Repair of Crown of Glass Furnace

No preheating required ; Least disruption to production

Excellent thermal shock resistance ; 1100℃ with water more than 30 cycles

Near zero thermal expansion coefficient

Capacity to produce very large blocks and in complex shapes

Zero expansion silica brick:
1. Main features:
1. The SiO2 content is greater than 99%, with excellent corrosion resistance and acid resistance
2. Low Fe2O3 content less than 0.1%, no pollution to products (such as molten glass, etc.)
3. Low flux index (Al2O3+2R2O) is less than 0.3%
4. The thermal expansion rate is close to zero, so there is no need to reserve expansion joints when repairing to increase the tightness of the masonry
5. Excellent thermal stability, the product will not burst during hot repair, and repair operations can be performed directly without stopping the furnace at high temperatures
6. After repair (hot repair), there will be no peeling and other phenomena, and it is safe and reliable for long-term use
To
2. Main purpose:
It is widely used in high-temperature thermal equipment such as glass melting furnaces, coke ovens, and hot blast furnaces. Especially high-temperature thermal equipment can be repaired arbitrarily without stopping the fire
