Glass wool processing production process

The processing and production process of glass wool mainly includes the following steps:

1. Raw material processing: the main raw material is glass fiber, which is obtained from the glass raw material by melting and spinning. Glass fiber has good insulating properties and high 2. temperature resistance. Other additives may include polyester fibers, resins, adhesives, etc.

2. Melting: In a high-temperature furnace, the glass raw material is melted into a liquid state.

3. Spinning: The molten glass liquid is sprayed through a special spinner onto a rotating fiber guide plate to form continuous glass fibers.

4. Stretching: The glass fibers are stretched into fine filaments by wind or air force. This process increases the softness and elasticity of the fibers.

5. Processing: Depending on the demand of the product, twisted, braided, relaxed, and other processing treatments may be carried out to make glass fiber products of different materials, types, and specifications.

6. Coating: Some glass fiber products may need to be coated to increase the load they can bear, abrasion resistance, waterproof, and other properties.

The above is the general processing of glass wool production process, the specific steps may vary depending on the type of product and production process.
