Overview
DM-IV Putty Sandability Tester is a new type of instrument designed and manufactured by JINGKELIAN brand according to GB/T1770-2008 national standard, which is specially used to evaluate the sanding performance of undercoating and putty.
Features
1. High Accuracy Stepper Motor
2. Touch screen control
3. Speed regulation range 0-135 times/min
4. The setting range is freely set 0-9999 times
5. Round-trip counting function
6. Test stroke 155mm
7. sanding head mass 570g +/- 15g
8. Equipped with 50 +/- 3g, 100 +/- 4g, 200 +/- 7g three counterweights
9. Manual suction cup test bench specification 250 * 90 * 45
10. Power supply 220V 50Hz 40W
11. Dimension 270 * 310 * 355mm
12. Single machine weight about 15kg
Principle
The instrument drives the sanding head to make a round-trip friction movement on the surface of the test plate through a stepper motor. By setting different sanding times and loading masses, the actual sanding process is simulated, so as to evaluate the sanding performance of undercoating and putty.
Applications
Evaluation of sanding resistance of undercoat, evaluation of sanding resistance of putty
Steps
Step 1 Turn on the power
2. Set the required number of times according to the on-screen instructions
3. Enter the test state
4. The preparatory test plate adsorption on the disk table
5. Plus the required weight
6. Adjust the button to set the desired speed
Step 7 Start testing
8. The instrument automatically stops after reaching the specified number of times
9. The next test will be automatically cleared
10. Click the reset button to clear manually
11. Repeat the test three times, selecting two close results as the basis for evaluation
12. Evaluate the sanding resistance of undercoating and putty according to the number of sanding and loading mass
Notice
• Tinplate size is 200 * 80mm, Film thickness 0.3-1
• The instrument has a cumulative function, so pay attention to the clearing operation
• Test results need to be evaluated based on two close test data
• Power supply voltage 220V 50Hz before use
• Pay attention to weight weight accuracy requirements: 50 +/- 3g, 100 +/- 4g, 200 +/- 7g
