Hongwo Sealing Gasket
Asbestos gaskets are common sealing materials in industrial equipment and pipelines. They effectively prevent leakage. The following is the manufacturing process for asbestos gaskets:
1. Raw Material Preparation: First, prepare the raw materials: asbestos fibers, rubber, and fillers. Asbestos fibers are the main material. Rubber boosts elasticity, and fillers improve sealing performance.
2. Asbestos Fiber Treatment: Remove impurities and control fiber length in the asbestos fibers. This will ensure the final product’s quality.
3. Mixing: Mix the treated asbestos fibers with rubber and fillers per a formula. Stir well to ensure an even mix of all materials.
4. Pressing and Shaping: Place the mixed raw materials into molds and press them into shape. The molds shape the raw materials with high heat and pressure.
5. Vulcanization Treatment: Place the formed asbestos gaskets in a vulcanization furnace. This will give them high resistance to heat, pressure, and corrosion.
6. Cut and shape the vulcanized asbestos gaskets. Make their edges smooth and neat. They must meet the required size and shape.
7. After the inspection, the team packages them for transportation and use.
8. Precautions:
During operation, protect your hands and lungs. Avoid contact with asbestos fibers.
Operators must wear protective equipment to avoid harm from raw materials.
Strictly control temperature and pressure during production to ensure stable product quality.
Mix raw materials strictly according to the formula ratio. This avoids unstable product performance due to an improper formula.
Control the vulcanization time and temperature. This ensures the product is fully and evenly vulcanized.
