The gypsum board covering paper production line and packaging paper project are divided into paper machine equipment installation, electrical instrument and pipeline installation, including paper machine workshop, pulp workshop and peripheral supporting engineering; PM6 paper machine is a paper machine equipment, pipeline and electrical instrument, oil and gas pipeline and process ventilation system with an annual output of 300000 tons of gypsum board protective paper.

1. Low weight: Gypsum board paper weight is only 120-180g/ m2, but it has very high tensile strength, which perfectly meets the requirements of high-grade gypsum board production. The board produced with gypsum board paper has very high performance in surface flatness, which makes it the best protective material for the production of large and medium-sized high-grade gypsum board.
2. High air permeability: Gypsum board paper has very large breathing space, which allows more water evaporation during the drying process of gypsum board production. It helps to increase production capability and efficiency.
3. Great heat permeability resistance: Gypsum board paper is more convenient for the control of shaping, slitting and turnover in gypsum board production, in production process, gypsum board paper keeps it’s strength and wetness, which helps to improve the yield of board production line.

1、 Overview of Paper Production Process for Gypsum Board

Gypsum board is a widely used building material, mainly composed of gypsum and paper. In the process of making gypsum board, paper plays a crucial role. Below we will provide a detailed introduction to the production process of paper from gypsum board:

2、 The process flow of producing paper from gypsum board

1. Preparation of raw materials

The main raw materials for producing paper from gypsum board are wood pulp and waste paper, which require a series of treatments and processing to ensure their quality and performance meet the requirements.

2. Pulping

Send the prepared raw materials to the pulp workshop for pulp processing. Various additives, such as thickener and foam agent, need to be added in the pulping process to adjust the viscosity and foam degree of the slurry.

3. Forming

The finished pulp is formed by a molding machine to produce paper of a certain specification and size.

4. Drying

The formed paper needs to be dried by a dryer to remove moisture and make it firm and flat.

5. Cut off

The dried paper needs to be cut into the required size and specifications.

6. Coating

The cut paper needs to be coated to increase its water resistance and weather resistance.

3、 The role of paper in the production process of gypsum board

Paper plays an important role in the production process of gypsum board. One is to increase the strength and toughness of gypsum board, making it more durable. The second is that paper can serve as a barrier to prevent gypsum slurry from penetrating along the wall. Thirdly, paper can enhance the fire resistance of gypsum board. Therefore, selecting high-quality paper is crucial for the quality and performance of gypsum board.
