Manufacturing Process
Mixing Phase
Step 1: Weigh all dry ingredients accurately.
Step 2: Homogenize Calcium Sulfate Dihydrate, Glass Fiber, Vermiculite, Aluminum Hydroxide, and Silica using a high-shear mixer.
Step 3: Gradually add starch while continuing to mix for uniform distribution.
Formulation Phase
Step 1: Transfer the dry mix to a controllable sheet-forming system.
Step 2: Introduce water to form a moldable slurry.
Step 3: Continuously form slurry into board precursor using rollers.
Step 4: Apply heat treatment to set the structure.
Finishing and Setting Phase
Step 1: Cool the semi-finished boards under controlled conditions.
Step 2: Trim boards to specified dimensions.
Step 3: Optionally apply a surface finishing treatment.
Usage Instructions
Install the gypsum board in areas requiring fire resistance. Cut to size and fix securely using appropriate fasteners. Follow local building codes and standards.
