2. Production Process of PVC Truck Tarpaulin

Step 1: Raw Material Preparation

• Select high-quality PVC resin, reinforcing fabric, and stabilizers.
• Check the physical properties of raw materials, such as density, tensile strength, and thickness consistency.

Step 2: Fabric Pre-treatment

• Clean, dry, and apply anti-static treatment before coating.
• Ensure the fabric surface is free of dust and impurities to improve PVC adhesion.

Step 3: PVC Coating

• Use single or double coating to evenly apply PVC slurry on the fabric surface.
• Control coating thickness, generally 0.4–1.0 mm, depending on application requirements.

Step 4: Heating and Curing

• Pass the coated fabric through high-temperature drying to allow full PVC adhesion and form a durable surface.
• Temperature: 160–200℃; Time: 3–5 minutes per layer to ensure stable physical properties.

Step 5: Post-processing

• Surface embossing to enhance anti-slip properties and appearance.
• Edge trimming, welding, and sewing to form the finished tarpaulin.
• Optional attachments: metal eyelets, reinforced edges for improved durability and usability.
