Construction of the viscoelastic anti-corrosion adhesive tape should also pay attention to what matters?

Release date:2016-07-27 The author: Click on:

Viscoelastic anti-corrosion adhesive tape and other types of anti-corrosion tape belong to the same attribute of the product, but they have their own between the respective differences, viscoat anti-corrosion tape is the ideal anti-corrosion protection products, with the construction process Simple and convenient, good sealing effect, long anti-corrosion life, complete environmental protection and other advantages. And widely used, mainly used in oil, natural gas, petrochemical, power, metallurgy, urban gas pipe network, water supply and other pipeline engineering and facilities in the metal pipe outside the anti-corrosion. Its advantage is efficient, long life, widely used in petrochemical, natural gas and other projects buried in the underground metal pipe outside the anti-corrosion. The following look at the use of this product precautions.

1. When the weather is cold, the ambient temperature is lower than 10 ℃ or the beginning of the tape when the adhesive tape harder, in order to ensure that the tape has a good bond strength, while eliminating the water vapor on the surface of steel, should be used to preheat the surface of the lamp Need to bake each roll tape head), to ensure the winding effect.

2. For the weld, if necessary, it is appropriate to use 30-50 mm width of the narrow tape reinforcement, first covered in the weld, and hand or wood smooth tool compaction.

3. Use appropriate mechanical or manual tools, in the coated primer on the lap according to the requirements of spiral winding tape, tape should maintain a certain tension, force to be uniform, making the tape layer tightly connected. The edges of the tape should be parallel and do not twist wrinkles. Both ends of the tape at the junction of more than 100 mm overlap. If necessary, in the previous section of the end of the tape on the base film coated with primer or full baking, to be dry after the other piece of tape at the beginning of the tape. The end of the end should be tightly pressed with a wooden smooth tool so that it does not tilt.

4. The use of machinery is to ensure the quality of the tape winding effective measures, hand-wrapped tape is difficult to achieve uniform surface quality and consistent tension, only in special circumstances, mechanical construction can not be carried out before they can be hand-wrapped, But should use a narrower tape.

5. On-site prefabricated tape can be cold or hot wrapped construction, can be the tube rotation (manual rotation or electric rotation), can also be winding equipment rotation, the tube should be reserved 150-200 mm welding allowance The

6. fill mouth, elbow, through the wall of the anti-corrosion tape should be used to narrow the width of the tape.

 

In the above article we have a very detailed description of the viscoelastic anti-corrosion adhesive tape on the relevant precautions, in fact, here is a proposal for everyone to try to make the tape to play the most efficient use of the effect, to buy a good Of the product is important, but in use should pay attention to some of the details of the problem, so as to ensure that its use will not decline.
