Pipeline lock wrapped around the anti-corrosion tape is often the phenomenon of bubbles, which is due to what causes it? Wrapped around the anti-corrosion tape in the sun is very prone to the phenomenon of bubbles, it is because the surface of the pipeline in the construction of the water did not wipe clean, easy to produce bubbles after heating. So, what are the reasons for that?
First, the first mention of the coating mentioned in the existence of wet steam blistering: This solution is to wrap the anti-corrosion adhesive tape before the addition to water, as far as possible after the temperature rise, the sun dried water and then wrapped, So there is no need to have water vapor, causing blistering.
Second, the anti-corrosion adhesive tape construction is not tight enough, resulting in steel and tape between the air is not squeezed, the sun exposure, more prone to bubbles.
Solution: polyethylene anticorrosive adhesive tape around when to try to tighten the tension to keep the same as possible, do not relax for a while
Third, the corrosion of foam: primer and glue between the chemical reaction caused by chemical substances cause blistering. Inappropriate primer and adhesive tape, the corrosion protection system may provide suitable adhesion for high performance coatings due to the absence of necessary adhesion or physical properties, resulting in the removal of certain solvents from the substrate.
Solution: try to use anti-corrosion adhesive tape comes with anti-corrosion primer, to avoid the use of corrosion with unqualified primer, no chemical debris primer.
The reasons for the proliferation of the coating is more complex, the above is the frequent occurrence of the three kinds of foaming problems to make some solutions, I hope my friends can strictly control, to avoid production and anti-corrosion in the production of blistering, resulting in the appearance of flat Of the coating.
