Production process of gypsum board

Gypsum board is a widely used building material with excellent fire resistance, sound insulation, thermal insulation, and decorative effects. The production process of gypsum board is relatively complex, involving multiple key steps to ensure the quality and performance of the product. The following is the main process of gypsum board production technology:

1、 Raw material preparation

The main raw materials for gypsum board are gypsum powder, cement, fiberglass mesh cloth, additives, and water. Gypsum powder is usually derived from natural gypsum or industrial by-product gypsum, and is used after calcination and grinding treatment. Other raw materials such as cement and additives also need to undergo strict screening and quality testing to ensure compliance with production standards.

2、 Ingredients and Mixing

On the production line, gypsum powder, cement, additives, and water are mixed thoroughly in the mixing equipment according to the predetermined formula ratio. The mixing process requires strict control of time and speed to ensure that various raw materials are evenly mixed and form a stable gypsum slurry.

3、 Forming

Pour the mixed gypsum slurry into the molding mold and apply a certain pressure through a press to evenly distribute and solidify the slurry in the mold. During the molding process, the temperature and humidity of the mold need to be precisely controlled to ensure the flatness and quality of the gypsum board.

4、 Dry

The formed gypsum board needs to be dried in a drying room. Drying rooms typically use a hot air circulation system to evaporate moisture from gypsum boards by heating the air. The control of drying time and temperature is crucial, ensuring that the gypsum board is fully dried while avoiding cracking caused by excessive drying.

5、 Cutting and trimming

The dried gypsum board is cut and trimmed as needed to achieve the specified size and shape. Cutting equipment usually adopts advanced automation technology to ensure cutting accuracy and efficiency.

6、 Packaging and Storage

Cut and trimmed gypsum boards are packaged to prevent damage during transportation and storage. Packaging materials are usually chosen to be moisture-proof and shockproof to ensure the integrity of the gypsum board.

In summary, the production process of gypsum board involves multiple stages, each of which requires precise control and management to ensure the quality and performance of the final product.
