Product Details
low thermal conductivity insulating silica brick for sale
Product Introduction:
The silica content is 93% or more. It has acid slag corrosion resistance and higher high temperature strength. The load softening start temperature is 1620~1670 °C. Long-term use at high temperatures does not deform. The thermal shock stability is low (heat exchange in water for 1~4 times). This residual expansion will make the joints tight and ensure good air tightness and structural strength of the masonry.
Advantage:
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C
Stable Capability, High Quality, Excellent Service, Competitive
price is the most important advantage of our products.
