QTY-32 Enamelled Cylindrical Bending Tester QTY-32 Paint Bend Cylinder Tester Measuring Paint Performance Tools 1pc

First, the scope of application     Paint film bending tester is mainly used for the determination of paint and varnish coating flexibility, is a measure of the performance of the coating one of the main indicators for the choice of paint varieties, the application has a great reference value.     Paint film bending tester is the evaluation of paint, varnish and related products coating, under standard conditions around the cylindrical shaft bending resistance or cracking from the metal plate on the performance of special equipment, in line with GB6742 national standards.   Second: 1. Working principle:     Bending radius of the different properties of the substrate is also different, depending on the coating at different bending radius of the crack or stripping the situation, and determine the flexibility of the coating film.   2. The main parameters: The diameter of the film bending test shaft is 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25 and 32 mm, respectively. Rotary handle adjustment s
