Polypropylene anti-corrosion tape use effect maintenance method

Release time:

Polypropylene anti-corrosion tape can bring us good anti-corrosion effect, but we need to correct construction. In addition, some work needs to be done to maintain the good performance of the effect. Then, let's learn about the method of maintaining the effect of polypropylene anticorrosive tape!

1. Do a good job in the derusting of the anti-rust tape. After washing and drying, it needs to meet the derusting standard, the pipeline is derusted, and the surface is sprayed with anti-rust primer.

2. The polypropylene anti-corrosion tape needs to be wound with special equipment to control a certain tension, the pipeline rotates at a certain speed, and the tape travels along the pipeline axis.

3, regular quality inspection of polypropylene anti-corrosion tape, found that the anti-corrosion layer problems in a timely manner to repair, damage repair work.

4. Before using the polypropylene anti-corrosion tape, the surface of the steel pipe needs to be treated, and the bumps and sharp corners should be polished to make the surface dust clear.

5. The primer is very important for the anti-corrosion effect of the polypropylene anti-corrosion tape in the later stage. The matching one needs to be stirred evenly in the container before applying the primer.

6. It is forbidden to apply primer or tape in dusty weather or rainy days. This affects the adhesion performance because the anticorrosion effect is poor.

7. The unwinding temperature of the tape shall not be less than 5 degrees before use. When the temperature is too low, it can be heated on the surface of the steel pipe to ensure the coiling effect.

8. When wrapping anti-corrosion tape, the force shall be uniform, wrinkles and fractures shall not appear, the edge seams shall be parallel, and the joints of the two ends of the tape shall not be less than 10cm overlapping.

polypropylene anticorrosion tape performance:

1. Crack resistance: reduce the number and size of cracks, effectively hinder the separation of aggregates, polypropylene fibers form a uniform random support system inside the concrete, effectively prevent the generation and development of primary cracks in concrete/mortar, and ensure uniform bleeding and settlement.

2, improve the impermeability: effectively suppress the generation of connected cracks, polypropylene fiber effectively suppress the generation and development of early shrinkage cracks and segregation cracks in concrete, greatly improve the density of concrete, improve the impermeability of concrete.

3, improve the wear resistance and impact resistance: improve the body interface bonding performance, polypropylene fiber can effectively control the concrete admixture bleeding phenomenon, reduce the separation of cement particles, sand particles, the formation of a more solid concrete surface.

4, improve frost resistance: adding polypropylene fiber can introduce trace air into the concrete. Therefore, free water damaged by concrete expansion and shrinkage under freeze-thaw cycles can enter these microbubbles to reduce early freeze-thaw damage.

5, high toughness: improve the ability to crack deformation, to improve the brittleness of great significance, polypropylene fiber can greatly improve the toughness of concrete.

The above is the use of polypropylene anti-corrosion tape to maintain the effect of the method, so that our effect is better, better to maintain the long-term effect, so we can carry out these related work after construction, improve our work efficiency.
