The cold-applied anticorrosion tape making machine is used to produce PE tape for protecting underground and overhead pipelines in industries such as oil, gas, petrochemical, and wastewater. The system primarily includes three components: a PE base film extrusion line, adhesive coating equipment, and slitting machinery.

The production process of cold-applied tape typically includes the following main steps:

1. Base Film Extrusion

   • Raw Material Preparation: Polyethylene (PE) is prepared as the base film raw material.

   • Extrusion Molding: The raw material is heated and melted in an extruder, then molded through a die to form a continuous base film.

   • Cooling and Shaping: The extruded base film is cooled and shaped using cooling rollers to ensure uniform thickness and consistency.

2. Adhesive Coating

   • Adhesive Preparation: Butyl rubber are prepared to ensure proper viscosity and stability.

   • Coating Process: The adhesive is evenly applied to one or both sides of the base film using coating equipment to form an adhesive layer.

3. Slitting

   • Slitting Preparation: The coated base film roll is prepared, and the parameters of the slitting equipment are adjusted.

   • Slitting Operation: The wide roll is slit into cold-applied tapes of the required width using slitting equipment.

   • Winding and Packaging: The slit cold-applied tapes are wound into rolls, packaged, and prepared for shipment.
