Cold-applied anticorrosion tape making machine is designed for producing the PE tape for protection of underground or overhead pipelines in oil, gas, petrochemical, and wastewater industries. The equipment mainly consists of three parts: PE base film extrusion production line, Adhesive coating equipment, and slitting equipment.
The process of making cold-wrapped tape:
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.
