Description

Technical Field

[0001] The present application relates to the technical field of adhesion measurement devices, and in particular to a polyethylene outer anti-corrosion layer adhesion measurement device. Background Art

[0002] The adhesion measuring instrument is suitable for measuring the adhesion ability of each coating film to the surface of the coated object. The coating adhesion is an important indicator for evaluating the coating quality. To measure the adhesion, it is necessary to first cut the anti-corrosion layer in the circumferential direction into a long strip with a width of 20mm to 30mm and a length of more than 10cm, and then lift one end and use the measuring instrument to uniformly pull up the polyethylene layer vertically on the pipe surface at a rate of 10mm / min.

[0003] With respect to the above-mentioned related technologies, the inventors found that during testing, the measuring instruments mostly directly hook the anti-corrosion layer to be measured on the outside of the steel pipe through the hook at the lower end. Since the diameter of the hook is small, the contact area between the hook and the anti-corrosion layer is small, which makes the pressure of the anti-corrosion layer at the hook larger, making the anti-corrosion layer at the hook prone to breakage, making it impossible for the measuring instrument to measure the anti-corrosion layer.
