Overview
QCJ-120B film Impact device is a YONGLIDA brand product, used to test the impact resistance of paint film. It is expressed as the maximum height of 120 cm when a fixed mass of heavy hammer falls on the test plate without causing damage to the paint film. There is no secondary rebound phenomenon after the impact head of this instrument impacts the test plate.
Features
1. Impact height 120cm, Division 1cm, high accuracy.
2. Drop weight mass 2000g, Impact force is stable.
3. Impact depth 2.5mm, punch diameter is 16mm, accurate design.
4. The aperture of the die base is 16.3mm, which matches the specifications of the punch.
5. No secondary rebound phenomenon to ensure test accuracy.
Principle
Impact performance of the paint film is evaluated by a fixed mass weight falling freely from different heights to the maximum height without causing damage to the paint film. There is no secondary rebound after the impact head impacts the test plate to ensure the Reliability of the test results.
Applications
Film impact resistance test, powder lame plating profile evaluation
Standards
GB/T6287.4-2000、GB/T1732-93、GB/T5237.4-2000、ASTM D2794-92
Steps
1. Prepare the test plate and fix it on the instrument.
2. Adjust the weight to the initial height.
3. Release the weight for Impact Test.
4. Observe whether the paint film is damaged and record the maximum non-destructive height.
5. Sexual repeability test to obtain accurate data.
Notice
• Check whether the components of the instrument are in good condition before use.
• Make sure the test plate is firmly fixed to avoid sliding.
• Operate in strict accordance with standards to avoid human error.
• Test accuracy by calibrating instruments regularly.
• Pay attention to safety to prevent the heavy hammer from accidentally falling.
