When it comes to the high - temperature parts of glass kilns, choosing the right refractory material is crucial. It directly affects the efficiency, service life, and product quality of the glass kiln. And here comes the high - quality silica brick for glass kilns that you absolutely can't afford to miss!
This remarkable silica brick is mainly composed of tridymite, cristobalite, etc. It is made from natural silica sand with an SiO₂ content of over 96%. This high - purity raw material is the foundation for its excellent performance. The high proportion of SiO₂ ensures its inherent high - temperature resistance and chemical stability.
High - temperature resistance: The silica brick can withstand extremely high temperatures, up to 1650°C. This allows it to maintain its structural integrity in the harsh high - temperature environment of glass kilns, ensuring continuous and stable operation of the kiln.
Volume stability at high temperatures: Unlike some common refractory materials that may experience significant volume changes at high temperatures, this silica brick has excellent volume stability. Its volume change rate is less than 1% under long - term high - temperature conditions, which helps to maintain the structural stability of the glass kiln and reduces the risk of cracks and damage.
No pollution to the glass liquid: Since it is made of high - purity materials, it will not release any harmful substances into the glass liquid during the melting process. This ensures the high quality and purity of the glass products, which is very important for high - end glass production.
Strong chemical corrosion resistance: It can resist the corrosion of various acids, alkalis, and molten salts in the glass kiln environment. Its corrosion rate is only about 0.1% per year, which is much lower than that of many common refractory materials, greatly extending the service life of the refractory lining in the glass kiln.
Low density: With a density of only 1.8 g/cm³, it is lighter than many common refractory materials. This not only reduces the load on the glass kiln structure but also saves energy during the heating and cooling process of the kiln.
| Properties | This Silica Brick | Common Refractory Materials |
|---|---|---|
| High - temperature resistance | Up to 1650°C | Around 1400 - 1500°C |
| Volume change rate at high temperatures | Less than 1% | About 3 - 5% |
| Pollution to glass liquid | None | May cause certain pollution |
| Chemical corrosion resistance | Corrosion rate about 0.1% per year | Corrosion rate about 0.5 - 1% per year |
| Density | 1.8 g/cm³ | 2.2 - 2.5 g/cm³ |
Many glass manufacturers have already benefited from using this high - quality silica brick. For example, a large - scale glass factory in Europe replaced their old refractory materials with our silica bricks. After one year of operation, they found that the service life of the kiln lining was extended by 30%, and the energy consumption was reduced by 15%. This not only saved them a lot of costs but also improved the quality of their glass products.
As you can see, this high - quality silica brick for glass kilns has significant advantages over common refractory materials in terms of composition, performance, and real - world applications. Missing out on this silica brick, you'll lose big! It is the ideal choice for the high - temperature parts of glass kilns. So, what are you waiting for? Make the smart decision now and take your glass production to a new level!
