Test application of T-type Bending Tester on composite silane film

The bending test refers to the requirements of the national standard GB/T13448-2006 for the bending test method. The QZW T-bending Tester is used to conduct a 180° bending test on the test piece with a size of 200 mm × 100 mm × 1 mm around itself. Observe the bending surface Cracking or peeling of the composite silane film, determine the minimum thickness multiple of the sample that prevents the coating from cracking or falling off, and record it as the T-bending value, the smaller the T-bending value, the better the bending resistance and adhesion when deformed, and at 0 T Better bending resistance,

The result of the composite silane film bending test is 1T. During the bending test, cracks can be observed on the composite silane film , but the composite silane film does not peel off after the adhesive tape is pasted; Peeling · This shows that 0 T is beyond the effective bending range of the composite silane film, but the adhesion after bending is very good, and the bending resistance is slightly poor.
