and aluminum silicate refractory fiber mat are both made of aluminum silicate refractory fiber. Aluminum silicate refractory fiber blanket is a thermal insulation refractory product made by dry needling process. Aluminum silicate fiber mat It is a heat-insulating and fire-resistant thermal insulation product formed by pressure.
1. Different production processes
Aluminum silicate fiber felt is produced in two ways. Aluminum silicate fiber felt needs to be formed by adding a certain binder and pressed. However, according to the different production processes of the binder part, it can be produced in two ways: wet method and dry method. The wet method is formed in a vacuum, using organic binders and fibers. The cotton slurry of a certain concentration is prepared, and is made into a plate-shaped thermal insulation material of a fixed size through vacuum filtration molding and drying processes. It has good strength and elasticity, but it cannot be bent during construction and can be cut.
2. Different materials
Aluminum silicate fiber blanket is a soft material that is spread out and used as insulation material to cover high-temperature pipes in high-temperature industrial furnaces. It can be used to reduce the thickness of the furnace wall to half of the original. The furnace wall can be reduced to 1/5-1/10 of the original weight, no oven is needed, the construction is convenient, and the energy saving effect is good.
3. Different forms of use
Aluminum silicate fiber felt has a shape, which is more convenient for furnace wall construction. If the location is too small, the plate shape can be cut and used. During construction, a bonding agent is used as an insulation layer. As the temperature rises, the organic bonding agent will be gradually burned away. When the temperature is high, the original shape is maintained by the interweaving of the fibers in the product. However, the surface of the fiber felt is not suitable for load-bearing, and its resistance to wind erosion is not very good. The tensile strength of wet-processed fiber mats is higher than that of dry-processed fiber mats.
At present, the wet method is mostly used, because after the wet method's refractory fiber mat is impregnated with a binder, its wind erosion resistance is better than that of the dry method. Moreover, the plate-shaped ones can be cut or trimmed for use at the corners of the furnace lining or complex furnace shapes. Aluminum silicate Fiber blankets are often used in industrial furnaces, kilns, furnace linings, pipe insulation, sound insulation and noise reduction, etc. Due to its fluffy material structure, aluminum silicate fiber felt is more suitable for use in various special fields such as mats, liners, and filter materials.
