Generally, the adhesiveness of polyethylene anti-corrosion tape is better. The viscosity of the tape is also an important indicator for judging the quality of the tape, but how to judge the viscosity of the polyethylene anti-corrosion tape?

      Many people choose the way to feel the adhesion of polyethylene anti-corrosion tape, but in fact, this is not the determining condition for determining the viscosity of polyethylene tape. If the polyethylene tape is mixed with impurities, it cannot be judged by this method. Judging the viscosity of polyethylene anti-corrosion tape, it is recommended that you use a spring balance to test the peeling strength of the finished anti-corrosion layer, and use a knife to cut a 10 mm wide, 100 mm long tape layer, and use a spring balance to open the 90 degree angle with the pipe wall. By judging the reading of the spring balance, it should be noted that the pulling speed cannot be greater than 300 mm per minute.
