Manufacturing Process of Aluminum Silicate Fiber Cotton

1. Raw Material Selection

The primary raw material for aluminum silicate fiber cotton is hard clay clinker. For high-purity and high-aluminum types, synthetic materials like high-purity alumina silica powder are used. Zirconium-containing types require composite materials of high-purity alumina silica powder and quartz sand.

2. Melting Process

The selected raw materials are fed into a resistance furnace for melting. The furnace provides the necessary high temperature to melt the materials, which is a critical step in the production process.

3. Fiber Formation

There are two main methods for forming the fibers:

Spraying Method: The molten material is sprayed through nozzles to form fibers.
Spinning Method: The molten material is spun to produce fibers. This method can produce both blown and spun fiber cotton.

4. Fiber Collection

The formed fibers are collected using a cotton collector or sedimentation device. This step ensures that the fibers are properly assembled and prepared for further processing.

5. Post-Processing (for specific products)

Depending on the final product requirements, additional processes may be applied:

Vacuum Forming: For products like ceramic fiber blankets, the fiber cotton may undergo vacuum forming to achieve the desired shape and density.
Needle PUNCHING: For ceramic fiber blankets, the fiber cotton is processed with plastic needles to enhance the product's strength and flexibility.

6. Quality Control and Packaging

Throughout the production process, quality control measures are implemented to ensure the product meets specified standards for thermal conductivity, mechanical strength, and chemical composition.
The final product is packaged, typically in inner plastic bags and outer woven bags, for protection during storage and transportation.

The manufacturing process of aluminum silicate fiber cotton is designed to produce materials with excellent thermal insulation properties, low thermal conductivity, and high-temperature resistance, making them suitable for a wide range of industrial applications.
