Overview
QCJ-120B paint film impact tester is a JINGKELIAN brand product, used to test the impact resistance of paint film, with a fixed mass weight falling on the test plate without causing damage to the film maximum height of 120 cm. The instrument Impact head Impact test plate after no secondary rebound phenomenon.
Features
1. Impact height of 120 cm, Graduation of 1 cm, high accuracy
2. Drop weight mass of 2000g, Impact force is stable
3. Impact depth of 2.5mm and diameter of the punch is 16mm to ensure the accuracy of the test
4. The aperture of the die base is φ 16.3mm and the radius of curvature is R2.5-3mm, which is reasonable in design
5. No secondary rebound phenomenon to avoid interfering with test results
Principle
The weight with the hook is fixed at the required height through the controller screw, and the height is determined by the coincidence of the scale of the slide barrel and the positioning mark line. Press the control screw to compress the controller spring, so that the round hole of the control slider is aligned with the round hole of the upper and lower covers of the controller, and the hook is peeling. The weight falls and strikes the punch rod, and the punch rod acts on the test plate on the pillow pad block. Then lift the weight body and take out the test plate to observe the paint film test.
Applications
Film impact resistance test
Steps
1. Fix the weight at the required height to ensure that the scale of the slide tube coincides with the positioning marking line
2. Press the control screw to make the hook peeling, and the heavy hammer falls and hits the punch rod.
3. Lift the heavy hammer body to take out the test plate
4. Observe the paint film test on the test plate
Notice
• Ensure accurate setting of Impact Height
• Check that the hammer and punch are in good condition
• Take out the test plate in time for observation after the test
• Avoid secondary rebound interference with test results
