Topower Attend The 38th CERAMICS CHINA 2024 Exhibitions ,During the exhibition, I met many customers and friends, and signed contracts at the exhibition site.
Topower produces ceramic products: including ceramic fiber blankets, ceramic fiber boards, ceramic fiber paper, ceramic fiber cloth, ceramic fiber modules, ceramic fiber cotton, ceramic fiber special-shaped parts and various lightweight bricks: lightweight mullite bricks, lightweight clay bricks, lightweight silica bricks, lightweight high-alumina bricks, etc.
Aluminum silicate ceramic fiber blankets are made by continuous melting and continuous spinning in a water-cooled wall resistance furnace without a lining, and are formed by double-sided needle punching; the fibers are long, thick and uniform in diameter, with high tensile strength, strong resistance to airflow erosion, and good thermal stability. Generally, they can be divided into two types: spinning blankets and blown blankets. Because the thickness of the fibers is different, the characteristics and uses of the two products are slightly different.
The aluminum silicate ceramic fibers used in spinning blankets are thicker and longer than those in blown blankets, so spinning blankets have higher tensile and flexural strength than blown blankets, and are suitable for heat insulation environments with high requirements for flexural and tensile properties.
The aluminum silicate ceramic fiber of the blown blanket is thinner than that of the spun wire blanket, so it is inferior to the spun wire blanket in terms of tensile strength and flexural strength. However, the thermal conductivity of the blown blanket is better, and it is suitable for environments that have low requirements on the tear resistance of the aluminum silicate ceramic fiber blankets but higher requirements on thermal insulation performance.
The raw materials used for lightweight refractory bricks can be divided into clay, silica, aluminum and mullite. The reason why lightweight bricks can insulate heat is that there are a large number of pores (including closed pores and open pores) in the brick body. The methods of creating pores include adding combustibles, foaming, and chemical methods. Lightweight refractory bricks have low compressive strength, poor slag resistance, and poor thermal vibration resistance, and cannot be in direct contact with glass liquid or flames.
