Product description
In terms of production technology, the preparation of aluminum silicate fiber blanket requires multiple processes, including raw material ingredients, melting, fiberization, blanket formation, etc. Among them, fiberization is one of the key steps. The molten high-alumina ceramic fibers are blown into filaments through high-speed airflow, and then weaved and compacted by a carpet-making machine to finally form a carpet-like material with a certain thickness and density. During the production process, various process parameters need to be strictly controlled to ensure product quality and performance.
Application of aluminum silicate fiber blanket
◆Industrial building materials kilns, heating devices, high-temperature pipe wall linings, electric boilers,
◆Gas turbine and nuclear power insulation chemical industry high temperature reaction equipment and heating equipment wall lining,
◆High-rise building fire protection, heat insulation kiln door, roof insulation, high temperature filtration material
Advantages of aluminum silicate fiber blanket
◆High temperature resistance, can withstand 1000-1430 degrees.
◆ Good thermal stability, can maintain good stability under high temperature environment
◆ It is light in weight and absorbs less heat when used as a thermal insulation material.
◆ Good toughness, can be bent and folded at will
◆ It can compensate for the deformation of the furnace shell so that there are no gaps between components.
◆Low thermal conductivity will bring high energy saving effect and have the ability to resist thermal shock.
