scope of use
The QTY-32-III paint film bending tester is mainly used to measure the film flexibility of paints and varnishes, and it is one of the main indicators to measure the performance of paints. It should be of great reference value.
QTY-32-III paint film bending tester is a special instrument for evaluating the cracking resistance or peeling performance of the coatings of paints, varnishes and related products when they are bent around the cylindrical axis under standard conditions.
Comply with GB6742, ISO1519, ASTMD522, DIN53152 implementation standards.
Structural principles and parameters
1. Principle
The ductility of the coating film to the substrate is also different with different bending radii. The flexibility of the coating film is judged according to the different bending radii or peeling conditions.
2. Main Specifications
The diameters of the shafts of the QTY-32-III paint film bending tester are 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 25, 32mm
Appropriate test plate size: length 120---150mm, width less than 80mm
Applicable to samples with a thickness below 1.0mm.
Use and operation
1. Apply the paint to the metal substrate
2. Carefully apply the film and dry it to ensure good reproducibility
3. During the experiment, bend the test substrate to 180° evenly within 1-2 seconds
4. Starting from the shaft rod with the largest diameter, test the diameter in descending order until the coating can be seen to break
5. In order to make the judgment of the result correct, the test should be carried out at a temperature of 23±2°C and a relative temperature of 50±5%.
Precautions when using
1. In order to prevent the coating from being damaged during the bending operation, a piece of thin paper can be attached to the coating surface of the model, and then inserted between the supporting plate and the adjusting handle for testing.
2. If you use a 10 times magnifying glass to observe the test results, it should be noted.
3. No cracking or peeling occurs with the smallest diameter mandrel, in which case the diameter of this mandrel shall also be indicated.
4. If the sample is an aluminum plate, its long side should be parallel to the rolling direction.
