As with the polyethylene heat shrink tape, the softening point of the polyethylene anticorrosive tape is relatively low, so the temperature of 38 ° C is used to test the cathodic stripping test for 48h and 7d at different cathodic polarization. As a result, the cathodic stripping distance of the polyethylene anticorrosive tape has no obvious correspondence with the change of the polarization potential. Basically, at a certain level, it is generally believed that the size of the cathodic polarization potential in the range of polyethylene The tape peel performance of the tape has no significant effect.
The following are the same as the "
In addition, with the extension of the test time, polyethylene anticorrosive tape cathode peel distance also increased; and the previous results can be seen, polyethylene anticorrosive tape cathode peel performance than the 3PE coating much worse; and heat shrink zone Than the polyethylene tape 48h cathode stripping distance to be larger, but the results of 7 days and quite, indicating that the polyethylene anti-corrosion tape cathode stripping distance development is slower than the heat shrink zone, probably because 3PE primer and steel attached Focus on hot melt and butyl rubber is better. Anti - corrosion tape
