Overview
CHENCHI CNY-3A Lasting Adhesive Tester is manufactured in accordance with the provisions of the national standard GB/T4851-2014 "Tack Test Method for Pressure Sensitive Adhesive Tapes", and is suitable for the Tack test of various adhesive products, such as pressure sensitive tapes, medical patches, self-adhesive labels, protective films, etc.
Features
1. Using a single-chip microcomputer for timing, the timing is more accurate and the error is smaller
2. Long time timing, up to 99h59min59s
3. Good Proximity Switch, Wear Resistance, High Sensitivity, Longer Service Life
4. Test plates and test weights designed in strict accordance with standards, the experimental plates are laser cutting process, the edges are neat and smooth, no burrs, no curling, to ensure the accuracy of the test data
5. The system is controlled by a microcomputer, with a PVC operation panel, membrane buttons and LCD liquid crystal display, which is convenient for users to quickly perform test operations and view data
6. Three test stations can simultaneously conduct multiple test projects
7. Automatic timing, locking, and other functions further ensure the high accuracy of test results
8. Newly added the delayed shutdown function of the LCD screen to prevent data loss caused by misoperation or sudden power failure of the external power supply
Principle
The test plate affixed with the sample is hung vertically on the test frame, and the weight of the specified weight is suspended at the lower end. The displacement of the sample sticking off after a certain period of time, or the time when the sample is completely disengaged, is used to characterize the ability of the adhesive tape to resist pulling off.
Applications
Pressure-sensitive tape, medical patch, self-adhesive label, protective film and other adhesive products
Standards
GB/T4851-2014 "Tack Test Method for Pressure Sensitive Adhesive Tape"
Steps
1. Hang the test plate attached to the sample vertically on the test rack
2. The lower end hangs the weight of the specified weight
3. Microcomputer control system start-up timing
4. Observe the amount of displacement or the time for complete dissociation of the sample
5. View the test data through the LCD LCD display
Notice
• Please confirm that the power supply is AC 220V, 50Hz before use
• Ensure that the edges of the test board are neat and smooth, with no burrs and no curling
• weight weight should be kept at 1000 +/- 1g (including tripod weight)
• Roller load should be kept at 2000 +/- 50g
• Be careful to prevent data loss caused by misoperation or sudden power failure of external power supply
• Avoid Undue Impact on Proximity Switches During Use
