Overview
The high-temperature resistant aluminum silicate roll cotton for kilns is mainly made of fire-resistant insulation cotton with high temperature resistance as the top priority. The colors are mainly white and bluish white, and it is processed and produced through multiple procedures such as high-temperature calcination, melting, spraying, gluing, spinning, and forming at temperatures above 1300 ℃. Mainly used as insulation and refractory materials for pipeline equipment in steel mills, power plants, petroleum, petrochemical, smelting, boilers, fertilizer plants, and thermal power plants. Aluminum silicate needle punched blanket has a soft texture, low density, low thermal conductivity, good waterproof performance, good acid and alkali resistance, high operating temperature, non-toxic, and pollution-free.
Product Details
Kiln high-temperature resistant aluminum silicate roll cotton
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. It is a regular type, with the letter code STD, and its temperature is 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.Kiln high-temperature resistant aluminum silicate roll cotton
