What is an Aluminum Silicate Fiber Blanket?
An aluminum silicate fiber blanket is a kind of refractory insulation material. Aluminum silicate fiber blanket is mainly divided into aluminum silicate fiber blowing blanket and aluminum silicate fiber spinning blanket. Aluminum silicate casting blanket because of the long fiber, small thermal conductivity, and thermal insulation performance is better than aluminum silicate blowing blanket. Most insulation pipe construction uses ceramic fiber swing silk blankets.

It is widely used in furnace lining, boiler, gas turbine, and nuclear power heat insulation welding to eliminate stress heat insulation, fire insulation, sound absorption, insulation, high-temperature filter medium, and kiln door seal.
1400 Model Ceramic fiber blanket with zirconium
1400 ceramic fiber blanket model meaning, that is, 1400 belongs to the classification temperature, also known as the classification temperature.
Ceramic fiber blanket material classification, according to the long-term working temperature from low to high divided into ordinary, standard, high purity, high aluminum, zirconium aluminum, and zirconium containing 6 grades. The zirconium ceramic fiber blanket corresponding long-term operating temperature is 1280℃.
Application of ceramic fiber blanket containing zirconium. Zirconium ceramic fiber blanket is generally used in the long-term working temperature between 1150℃-1300℃ industrial kiln wall lining, and backing material. Industrial kiln masonry expansion joint material, furnace door, top cover insulation seal. Thermal insulation sealing material for high-temperature pipelines. High-temperature insulation gasket with long-term operating temperature below 1280℃. Raw materials for processing zirconium ceramic fiber modules/folding blocks.
Characteristics of zirconium-containing (zircon-quartz) aluminum silicate fiber blanket
Zirconium-containing aluminum silicate fiber blanket is a high-temperature resistance grade of ceramic fiber conventional models. Strictly speaking, a zirconia-containing aluminum silicate fiber blanket is divided into low zirconium type and high zirconium type.
- Low zirconium type, theoretical classification temperature 1400 degrees, 24-hour operating temperature 1200 degrees. The content of zirconia is 5%-7%.
- High zirconium type, theoretical classification temperature 1430 degrees, 24-hour operating temperature 1260 degrees. The content of zirconia is 15%-17%.
Properties of zirconium containing refractories
Zircon refractory products are made of natural zircon sand and are acidic materials. Zirconium refractory has good slag resistance, low thermal expansion rate, and thermal conductivity decreases with increasing temperature. High softening temperature under load, high wear resistance, and good thermal shock resistance have become important materials in various industrial fields.
Zircon refractory has high resistance to acid slag and glass but also has the property of non-penetration of aluminum, and aluminum oxide slag. Therefore, good results have been obtained on the bottom of the aluminum smelting furnace.
1430℃ Zirconium Aluminum Silicate Blown Fiber Blanket
The production process of zirconium-containing aluminum silicate-blown fiber blanket. Zirconium-containing aluminum silicate fiber blanket is made of fiber cotton through needling, heat setting, cross – and – cross-cutting, winding, and other processes. All kinds of needled blankets have the same excellent properties as the corresponding loose aluminum silicate fiber cotton and have excellent tensile strength. The needled blanket has a uniform texture and a flat surface.
The needled blanket with different bulk densities and thickness provides users with a wide range of materials to obtain the best heat insulation structure and energy-saving benefits.
The working temperature of a zirconium-containing aluminum silicate blown fiber blanket depends on the material use condition, the type of heat source, and the environment atmosphere.
Technical characteristics of zirconium-containing aluminum silicate-blown fiber blanket
- Low thermal conductivity and low heat capacity
- Excellent thermal stability and thermal shock resistance
- Excellent tensile strength
- Excellent heat insulation, fire prevention, and sound absorption
Application of zirconium-containing aluminum silicate-blown fiber blanket
- Industrial building materials kiln, heating device, high-temperature pipelining
- Electric boiler, gas turbine, and nuclear heat insulation
- Wall lining of high-temperature reaction equipment and heating equipment for the chemical industry
- Fire prevention and heat insulation of high-rise buildings
- Heat insulation of furnace door and top cover
