PE Cold Applied Tape Making Machine for Pipeline Anticorrosion WrapProduct Description
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.
Technological processes
The production process of cold-applied tape typically includes the
following main steps:
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.
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.
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.
