Kiln insulation aluminum silicate felt

Kiln insulation aluminum silicate felt

Aluminum silicate plate is made by melting selected high-quality gemstones in an electric furnace above 2000 ℃, mechanically blowing them into fibers, and uniformly adding special binders, oil repellents, and water repellents through heating and solidification. Mainly used for thermal insulation in the power industry, power boilers, steam turbines and nuclear power plants, fire insulation in the shipbuilding industry, fire insulation in the construction industry, fire doors, and wall lining of high-temperature reaction equipment and heating equipment in the chemical industry. Aluminum silicate needle punched felt, also known as aluminum silicate cotton or aluminum silicate fiber felt. It is mainly used as a fireproof insulation layer in high-temperature equipment such as steel mills, power plants, petroleum, chemical, boilers, etc. It is divided into two categories: wire throwing type and blowing type, which are further divided into ordinary type, standard type, high-purity type, high aluminum type, and zirconium containing type. Each level increases with the increase of temperature resistance. The main differences are color, slag ball content, tensile strength, and temperature resistance. Aluminum silicate needle punched blanket, as a type of insulation refractory material, can be classified into six different types according to different temperatures. One is the regular type, with the letter code STD and a temperature of 12600 degrees Celsius. The second type is high aluminum type, with the letter code HA, and its temperature is 1400 degrees Celsius. The third type is zirconium containing type, with letter code ZA and a temperature of 1430 degrees Celsius. The fourth type is high-purity, with the letter code HP and a temperature of 1300 degrees Celsius. The fifth type is the standard type, with a temperature of 1260 degrees Celsius. The national standard for aluminum silicate fiber blanket is 96kg-128kg, with a thickness ranging from 10mm to 90mm. Customers can customize products according to their own requirements, and choose the appropriate one instead of expensive ones. Uniform, slender, and numerous glass fibers create resistance to air in high-temperature glass wool products and are arranged perpendicular to the direction of heat transfer, effectively preventing heat transfer and reducing heat loss. Sound absorption and noise reduction not only provide insulation for equipment, but also have the function of sound absorption and noise reduction, improving environmental quality. The characteristics of uniform durability, slender fibers, tight connections, and no slag balls enable high-temperature glass wool to avoid deformation, accumulation, and sharp decline in insulation performance caused by other insulation materials after a period of use or vibration. The chemical composition of non corrosive aluminum silicate fiber blanket and binder minimizes the content of soluble chloride ions at high temperatures, maintains a pH value between 7-8, and does not cause corrosion to insulated equipment and pipelines. After boiling continuously at 100 degrees Celsius for 96 hours, the quality, density, and thermal conductivity of the water-resistant aluminum silicate fiber blanket did not show significant changes. This performance has passed the water resistance test of the National Glass Fiber Product Quality Supervision and Testing Center.
