Coating process: Apply the formulated coating glue directly on the fabric evenly with a spatula.
Adjust the tension of the grey fabric, press down the scraper, adjust the angle of the scraper, and control the coating amount (g/m2).
After drying at an oven temperature of about 160°C, it is directly wound on the A-frame after cooling.

Calendering process: The raw materials used include: PVC resin, calcium powder, DOP dioctyl resin and other auxiliary materials.

Process flow: According to the formula, put the required raw and auxiliary materials into the high-speed mixer and mix them evenly for about 8 minutes, then enter the high-speed internal mixer, and pass the temperature control of 140℃-150℃, after the initial mastication for about 8 minutes, It is sent from the hopper to the two rollers for smelting, fully plasticized, and then sent to the filter. Through the multi-layer filter, the impurities are removed to ensure the quality of the PVC film. Finally, it is sent to the Calendering host by the conveyor belt and controlled by four rollers. The PVC film of the required thickness is directly pressed on the coated grey cloth through the embossing roller and rubber roller, and is directly wound on the A-frame after cooling.

Through a complete set of Process flow, it is necessary to ensure that the thickness error of the PVC film is controlled within ±1 silk (1 mm = 100 silk), without trachoma, to ensure the color difference requirements, the peeling fastness between the PVC film and the gray fabric and other quality requirements.
