In the modern glass manufacturing industry, glass kilns play a crucial role. However, the industry is facing numerous challenges. High - temperature operations, chemical corrosion, and the need for long - term stable production put forward strict requirements for the materials used in glass kilns. Against this backdrop, high - quality silica bricks for glass kilns have emerged as a game - changer.
Silica bricks for glass kilns are made from natural silica sand with an SiO₂ content of over 96%. This high - purity SiO₂ content is the key to their excellent high - temperature resistance. Compared with other refractory materials, silica bricks can withstand temperatures up to 1600°C. For example, in a certain large - scale glass factory, after replacing traditional refractory bricks with our high - quality silica bricks, the kiln could operate stably at 1580°C for a long time, while the traditional bricks could only withstand a maximum temperature of 1500°C.
| Performance Indicators | Our Silica Bricks | Similar Products |
|---|---|---|
| High - Temperature Volume Stability | The volume change rate at 1500°C for 24 hours is less than 0.2%. | The volume change rate at 1500°C for 24 hours is about 0.5%. |
| Anti - Chemical Corrosion | After 100 days of immersion in a common glass - making chemical solution, the corrosion depth is less than 1mm. | After 100 days of immersion in the same solution, the corrosion depth is about 3mm. |
| Density | The density is about 1.8g/cm³, which helps reduce the overall weight of the kiln. | The density is about 2.2g/cm³. |
In the glass production process, the high - temperature stability of silica bricks ensures a stable internal environment of the kiln, which is beneficial to the uniform melting of glass raw materials and improves the quality of glass products. For instance, a glass factory reported that after using our silica bricks, the defective rate of glass products decreased from 5% to 2%.
In terms of production efficiency, the excellent anti - chemical corrosion performance of silica bricks reduces the frequency of kiln shutdowns for maintenance. A glass enterprise found that the maintenance cycle of the kiln was extended from once every 6 months to once every 12 months, greatly improving production efficiency. Moreover, the low density of silica bricks reduces the load on the kiln structure, which also contributes to cost - saving in the long run.
For customers at the decision - making stage, they usually focus on product performance, cost - effectiveness, and long - term benefits. Our high - quality silica bricks for glass kilns perfectly meet these needs. The outstanding performance ensures stable production, the reduced maintenance cost improves cost - effectiveness, and the long - term stable operation brings long - term benefits.
In conclusion, our high - quality silica bricks for glass kilns have significant advantages in high - temperature resistance, volume stability, anti - chemical corrosion, and density. These advantages not only ensure the quality and efficiency of glass production but also reduce the maintenance cost of kilns. We sincerely encourage you to choose this high - quality silica brick to bring better economic benefits to your glass production business.
