Solving the Construction Challenges of Low-Alkali Borosilicate Glass: The Fused Silica Brick Solution

In the construction of low-alkali borosilicate glass, numerous challenges often emerge, such as the high temperature requirements of the melting process and the corrosion of the kiln lining. However, fused silica bricks offer a promising solution to these problems. Fused silica bricks are high-purity, corrosion-resistant refractory bricks produced by the Sunrise factory, specifically designed for the upper walls of kilns and particularly suitable for the construction of low-alkali borosilicate glass.

Unique Characteristics of Fused Silica Bricks

Fused silica bricks possess several remarkable characteristics that make them ideal for use in the construction of low-alkali borosilicate glass kilns. Firstly, they have a small coefficient of thermal expansion, which means they can withstand significant temperature changes without cracking or deforming. This property is crucial in a kiln environment where temperatures can fluctuate rapidly during the melting and cooling processes. According to industry data, fused silica bricks have a thermal expansion coefficient of only about 0.5 - 0.8×10⁻⁶/°C, much lower than many other refractory materials.

Secondly, they exhibit excellent thermal shock stability. This allows them to resist sudden temperature changes without damage, ensuring the long - term stability of the kiln structure. In addition, at high temperatures, fused silica bricks have high viscosity and strength, which can effectively resist the erosion of molten glass and the impact of high - temperature airflow. Their strong slag resistance and impact resistance further enhance the durability of the kiln.

Moreover, fused silica bricks have a low thermal conductivity, which helps to reduce heat loss from the kiln, improving energy efficiency. They also have small drying and firing shrinkage, which ensures the dimensional accuracy of the kiln lining during the construction process. This precision is essential for maintaining the proper operation of the kiln and preventing potential safety hazards.

Necessity and Advantages for Low - Alkali Borosilicate Glass Construction

The construction of low-alkali borosilicate glass requires a high - quality refractory material that can withstand the harsh conditions of the melting process. Fused silica bricks meet these requirements perfectly. Their high purity ensures that they will not contaminate the molten glass, which is crucial for maintaining the quality of the final glass product. The corrosion resistance of fused silica bricks protects the kiln lining from the corrosive effects of the low-alkali borosilicate glass melt, extending the service life of the kiln and reducing maintenance costs.

Real - World Case Studies

A well - known glass company once faced frequent kiln lining failures in their low - alkali borosilicate glass production line. After switching to fused silica bricks from the Sunrise factory, the service life of the kiln increased by more than 30%. This not only reduced the frequency of kiln repairs but also improved the overall production efficiency and product quality. Another case shows that the energy consumption of a kiln decreased by about 15% after using fused silica bricks, thanks to their low thermal conductivity.
