Overview

Aluminum silicate needle punched blanket (1) adopts advanced CWCN equipment and double-sided needle punched blanket assembly line. Various aluminum silicate fiber needle punched blankets are made from fibers made of different materials (such as sapphire, SiO2, Al2O3, zircon sand, etc.) through processes such as settling needle punching, heat setting, longitudinal and transverse cutting, and rolling.

production process

　　Aluminum silicate needle punched blanket (1)Adopting advanced CWCN equipment and double-sided needle punched blanket assembly line. Various aluminum silicate fiber needle punched blankets are made from fibers made of different materials (such as sapphire, SiO2, Al2O3, zircon sand, etc.) through processes such as settling needle punching, heat setting, longitudinal and transverse cutting, and rolling. The texture is uniform, the surface is flat, and it has excellent tensile strength. As the aluminum silicate needle punched blanket itself does not contain binders, it greatly improves the heat resistance.

application

Insulation for electric boilers, gas turbines, and nuclear power plants.

Wall lining for high-temperature reaction equipment and heating equipment in the chemical industry.

High temperature pipelines, special-shaped pipelines, and industrial kiln wall linings. Thermal insulation for stress relief of welded components. Thermal insulation for stress relief of special-shaped metal castings. The top cover of the kiln door is insulated.
