PVC sheet: ( Taking the calender production as an example)
1. Preparing softened and melted PVC material, Feeding the melted plastic material into calender, so that the material is gradually calendered to be a (sheet) having a desired thickness;
2. Sending the sheet material into a water bath tank;
3. Sending the cooled flexible plastic sheet to pass a water removing equipment in which more than one soft rubber roller and metal roller cooperate with other supplemental water removing means;
4. Sending the plastic sheet coming out of the water removing equipment to pass a series of heating rollers coated with water-absorbent material;
5. Winding up the plastic sheet into rolls
