Aluminium Silicate Ceramic Fiber Board: A Versatile Solution for Thermal Insulation and Fire Protection

Dec 19, 2023

In industries where high temperatures and fire hazards are prevalent, effective thermal insulation and fire protection solutions are essential. Aluminium silicate ceramic fiber boards have emerged as versatile materials that address these needs. These boards offer excellent thermal insulation properties, high temperature resistance, and exceptional fire protection capabilities.

Understanding Aluminium Silicate Ceramic Fiber Boards

A. Overview of Aluminium Silicate Ceramic Fiber:

Composition: China aluminium silicate ceramic fiber modules is a lightweight and durable material composed of high-purity alumina-silica fibers. These fibers exhibit excellent thermal stability, low thermal conductivity, and resistance to thermal shock.

Manufacturing Process: The production of aluminium silicate ceramic fiber boards involves the melting and spinning of raw materials into fibers, followed by a bonding process to form a rigid board structure. The resulting boards possess a uniform composition and consistent thermal properties.

B. Key Features and Thermal Properties:

Thermal Insulation: Aluminium silicate ceramic fiber board provide exceptional thermal insulation, minimizing heat transfer and reducing energy loss. Their low thermal conductivity helps maintain stable temperatures in industrial furnaces, kilns, and other high-temperature environments.

High Temperature Resistance: These boards exhibit remarkable resistance to high temperatures, making them suitable for applications that involve extreme heat. They can withstand temperatures up to 1600°C (2912°F), ensuring long-term performance in challenging thermal environments.

Low Heat Storage: Aluminium silicate ceramic fiber boards have low heat storage capacity, meaning they require less energy to heat up and cool down. This characteristic contributes to energy efficiency, reducing operational costs and promoting sustainable practices.

Applications of Aluminium Silicate Ceramic Fiber Boards

A. Industrial Furnaces and Kilns:

Furnace Lining: Aluminium silicate ceramic fiber boards are widely used as furnace linings in various industries, including steel, glass, ceramics, and non-ferrous metals. Their excellent thermal insulation properties help maintain high temperatures within the furnace, improving process efficiency and reducing heat loss.

Kiln Construction: These boards find application in kilns for pottery, ceramics, and other heat treatment processes. They provide insulation and protection against heat radiation, ensuring consistent and controlled heating for optimal product quality.

B. Heat Shielding and Insulation:

Automotive and Aerospace Industries: Aluminium silicate ceramic fiber boards serve as effective heat shields and insulation in automotive and aerospace applications. They protect sensitive components from excessive heat, minimizing the risk of damage and ensuring the safety and performance of vehicles and aircraft.

Power Generation: In power plants, aluminium silicate ceramic fiber boards are used for insulation in boilers, furnaces, and exhaust systems. They help maintain high temperatures, enhance energy efficiency, and provide fire protection, contributing to the safe and efficient operation of power generation facilities.

1430C Ceramic Fiber Vacuum formed Products

While both aluminum silicate and alumina fibers are commonly used in ceramic fiber products, they have different temperature ratings and properties:

Aluminum silicate fibers are often used in applications with lower temperature requirements, typically up to around 1100C (2012F). They offer good thermal insulation properties and are commonly found in ceramic fiber blankets, boards, and modules.

On the other hand, alumina fibers have higher temperature resistance and can withstand temperatures up to approximately 1430C (2606F). These   are used in vacuum-formed products, such as alumina fiber boards and shapes, which are designed for applications that require insulation and stability at elevated temperatures.
