Overview
QHZ film scratch tester is YONGLIDA brand for evaluating the performance of the coating instrument, through the film sample coating by the size of the scratch scratch resistance to characterize the coating strength, Hardness, adhesion.
Features
1.Scribing needle length 60mm, traverse speed 20~ 40mm/s adjustable
2. The diameter of the scribing steel ball is 1mm, and the load range is 0~ 2000g.
3. The angle between the scribing needle and the test sample is 10~ 15 °, with a minimum increment of 50g
4. Power 15W, Power supply voltage 220V 50Hz
5. Dimension 180 * 230 * 280mm, instrument weight 10kg, compact and portable
Principle
The penetration resistance of the coatings was measured by marking the sample coatings to characterize the strength, Hardness and adhesion performance of the coatings.
Applications
Paint performance assessment
Steps
1. Prepare the paint film sample
2. Set the scribing parameters (angle, load)
3. Start the instrument for marking test
4. Observe and record coating penetration resistance
Notice
• Power supply voltage 220V 50Hz
• Scribe pin load settings need to be adjusted in a minimum increment of 50g
• Check that the angle between the scribe and the sample is within 10~ 15 ° before the test
• Pay attention to safety during operation and avoid scratches
