Reasons affecting the anti-corrosion life of viscoelastic anti-corrosion tape

As we all know, the anti-corrosion life of viscoelastic anti-corrosion tape is affected by many aspects. Although the product itself has stable performance and good anti-corrosion effect, if some details are not handled properly, its service life will be reduced. Today we Let’s learn about the reasons that affect the anti-corrosion life of this product.

1. Performance of viscoelastic anticorrosive tape

1. Each kind of anti-corrosion material has a certain scope of application. Therefore, it is necessary to comprehensively consider the operating conditions of the pipeline, soil conditions, construction environment, process requirements and economic rationality, and then select a suitable anti-corrosion layer material. It has a good Electrical insulation.

2. Good resistance to cathodic peeling strength.

3. Sufficient mechanical strength and certain impact strength.

4. Good bending resistance and wear resistance.

5. Good chemical stability, good resistance to atmospheric aging, and sufficient heat and cold resistance.

6. Low water absorption and good anti-microbial performance.

2. Pipeline surface treatment quality

The quality of the surface treatment is directly related to the adhesion between the viscoelastic anticorrosive tape and the steel pipe. If the treatment is not good, it will easily cause blistering, warping, and rust back. The surface treatment must meet the specified requirements and rust removal grade standards, and must have a certain degree of roughness. The roughness and rough shape should be determined according to the thickness of the anti-corrosion layer. If the roughness is too small, it will affect the quality of the interface bonding, and if it is too large, "rust" will occur. The roughness and its rough shape are related to the type, particle size, formula and rust removal process used in the treatment.

Three, construction method

We understand the requirements of three-point material and seven-point construction. The construction quality of viscoelastic anticorrosive tape directly affects the anticorrosion effect of the anticorrosion layer. Depending on the construction environment, manual winding machinery or electric winding machinery can be selected. The tape winding requirements are: to ensure a certain winding tension, tension, and flat winding.

In summary, we can know that viscoelastic anticorrosive tape is affected by various factors. Therefore, when using it, it is required to determine whether the surface impurities of the object are cleaned up, and the construction methods, to do a good job of these phenomena, and its service life It can be extended, but if some natural disasters are encountered, these will discount the anti-corrosion effect of the product and reduce its service life.
