1,Description of Mullite Block For Glass Kiln Pond Bottom
Mullite brick for glass furnace bottom is a new product developed and produced by our factory in recent years according to the needs of large glass factories. It is laid on the glass furnace bottom, replacing the traditional clay brick. The product uses high-purity synthetic mullite sand as the main raw material, and is poured and molded by high-strength vibration equipment. The overall purity of the product is high, the pollution to liquid glass is small, the corrosion resistance to liquid glass is strong, the thermal shock stability is good, and the product structure is compact. After using by users, its use effect is much better than that of clay brick, which is 5-7 times of the service life of traditional clay brick, greatly prolongs the maintenance cycle of glass furnace, and saves costs for users. Once the product comes out, it has been praised by users.

3, Characteristics of Mullite Block For Glass Kiln Pond Bottom:
1) High purity, less impurities and good compactness,The Fe2O3 content of the product is low, the standard is ≤ 1.0%, the actual content is 0.5 ~ 0.7%, and the content of other impurities is trace. The main components of the product are Al2O3 and SiO2, which basically does not pollute the liquid glass. The traditional clay brick, with Fe2O3 ≤ 1.5%, and impurities such as TiO2, K2O, Na2O, MgO, Cao, has much lower resistance to liquid glass corrosion than mullite brick
2) Wear resistance, good scour resistance,The structure of mullite brick is mainly acicular and columnar mullite, with low liquid content. It has good structural stability, thermal shock resistance and erosion resistance at high temperature. Even if the product is damaged by liquid glass, the resistance of mullite brick is far greater than that of traditional clay brick, which depends on the internal grid acicular structure of mullite brick
3) Good resistance to alkaline corrosion and peeling,Mullite brick is neutral refractory brick, while traditional clay brick is acidic refractory brick. Therefore, the corrosion resistance of mullite brick to alkaline glass is much better than traditional clay brick. The spalling resistance of mullite brick is better than traditional clay brick. Even if it is eroded by glass, it will not spall like traditional clay brick. Therefore, the application effect of mullite brick is better Much better than traditional clay bricks.
4,Application:Applied to the bottom of glass tank
5, Apply effect：Thick masonry with tight overall structure, Small gap, 2-3 times better than clay brick
6,Our company promises to customers: to provide free technical exchanges and services with customers, and to provide samples to customers free of charge without any sample fees.
7,Achievements generated: Our company has previously shipped 120 tons to Oman.
