Insulation Ceramic Fiber Blanket For Sale ,Customer In Australia Ordered 22 Tons
Aluminum silicate fiber blanket is a high-performance inorganic fiber thermal insulation material, which is mainly made of high-quality ceramic fiber (aluminum silicate fiber) through a special needle punching process. This material has been widely used in the industrial field due to its excellent high temperature resistance, thermal insulation, fire retardancy and chemical stability. Aluminum silicate needle punched blanket can withstand high temperatures of up to 1000℃ and maintain structural integrity. At the same time, it has extremely low thermal conductivity, effectively reducing heat transfer and saving energy. It is suitable for thermal insulation in various occasions such as industrial kilns, high-temperature pipelines, heating equipment, heat treatment furnaces, and building structures that require high fire resistance.
There are two common types of aluminum silicate fiber blankets: standard type and high aluminum type. There are many differences between them.
1. High temperature resistance
The long-term use temperature of standard aluminum silicate needle punched blanket is generally around 900-1000℃. Within this temperature range, it can maintain good physical and chemical properties, effectively block heat transfer, and meet the insulation needs of many general industrial equipment.
Due to its high alumina content, high aluminum silicate needle punched blanket has more excellent high temperature resistance. The long-term use temperature can be as high as 1200-1300℃. In high temperature environment, it can still maintain a stable structure and thermal insulation performance, and is suitable for places with extremely high temperature requirements such as high temperature industrial furnaces.
2. Density and strength
The density of standard aluminum silicate needle punched blanket is usually between 96-128kg/m³. Its density characteristics determine that it has a certain flexibility and is convenient for construction and installation. In terms of strength, it can withstand a certain degree of pressure and tension, but relatively speaking, its strength under high load is not as good as that of high-aluminum type.
The density of high-aluminum aluminum silicate fiber blanket is generally 128-160kg/m³, and the relatively high density makes it have better compressive and tensile strength. In some industrial environments that need to withstand large external forces, such as the wrapping of high-temperature pipes, the high-aluminum type can better maintain its shape and integrity to avoid damage due to external forces.
4. Price and application scenarios
The composition and performance characteristics of the standard aluminum silicate needle-punched blanket make the price of the standard aluminum silicate needle-punched blanket relatively low. It is widely used in the thermal insulation of general industrial equipment, such as ordinary boilers, reactors and other equipment with not particularly high temperatures. In projects that are more sensitive to cost and do not have extremely high temperature requirements, the standard type is a good cost-effective choice.
The price of high-aluminum aluminum silicate needle-punched blanket is usually higher than that of the standard type because of its high performance. It is mainly used in high-temperature industrial fields, such as high-temperature furnaces in the steel, ceramic, glass and other industries. These environments have strict requirements on the high temperature resistance and high strength of thermal insulation materials. High-aluminum aluminum silicate needle-punched blanket can meet these needs well.
