Everyone should be familiar with polypropylene anti-corrosion tape. The product uses butyl rubber modified asphalt as the anti-corrosion rubber layer, and the tape operation is relatively simple. Because of this characteristic, it is widely used in the industry, so, let's learn about the winding method of polypropylene anticorrosive tape!

1, first to apply primer. When we use polypropylene anti-corrosion tape to coat the primer, we should use the matching primer. When stirring the primer, be sure to stir evenly before use. After coating, the tape can be wrapped in about 10 minutes.

2. Surface treatment work: The surface treatment work is mainly to remove rust, welding slag and pollutants from the tape. We must ensure that the polypropylene anti-corrosion tape is clean and dry during the use of the tape.

3. Backfilling in the ditch: As we all know, polypropylene anti-corrosion tape is subjected to quality inspection after treatment, but after the quality inspection is qualified, the backfilling in the ditch can be carried out. When backfilling the trench, it is necessary to pay attention to the integrity of the tape.

When winding polypropylene anti-corrosion tape, it is necessary to select the appropriate adhesive tape width in strict accordance with the specifications; according to the requirements of the overlap of the tape width on the primed surface, the spiral winding method is used to make the winding direction consistent with the welding direction. And maintain a certain tension of the polypropylene anti-corrosion tape, make the force uniform, keep parallel, and do not distort wrinkles, so that the tape layer is in close contact with the surface of the pipe. Where the adhesive tape at both ends is connected, an overlap of more than 100mm is required. Apply primer to the end surface of the anticorrosion coating in the front section if necessary. Please use a wooden smooth tool to close the end to avoid floating. In order to easily generate bubbles in areas with high temperatures and areas with large temperature differences, a 24-hour shading method is adopted after winding.
