Overview
YONGLIDA QGZ-24 automatic paint film drying time tester adopts a circular trajectory scribing design, which is mainly used to measure the drying time of paint film and putty film. The instrument is equipped with four kinds of scribing needles with different radii, and the trajectory period is 24 hours/rev.
Features
1. Equipped with 4 different radius scribing needles (R0.25mm, R0.5mm, R1.0mm, R1.5mm)
2. Using circular track scribing design
3. The track period is 24 hours/revolution
4. Suitable for the determination of drying time of paint film and putty film
Principle
The instrument makes a circular trajectory movement on the surface of the sample through four different radii of the scribing needle, and judges the drying state of the paint film and putty film by observing the change of the scribing needle trajectory, and completes the determination of the drying time.
Applications
Determination of drying time of paint film, determination of drying time of putty film
Steps
1. Prepare 200 × 200 × (0.2~ 3) mm size specimens
2. Select the appropriate scribing needle specification
3. Start the instrument for circular trajectory testing
4. Observe the change of the scribing track
5. Record drying time data
Notice
• Ensure that the sample size meets the requirements of 200 × 200 × (0.2~ 3) mm
• Select the appropriate needle specification according to the test requirements
• Note that the operating track period of the instrument is 24 hours/revolution
• Pay attention to observe the change of the scribing track during the test
