Overview
JINGWEN JW207A-3p tape holding force testing machine is a professional testing equipment manufactured in accordance with the provisions of the national standard GB/T4851-2014, which is suitable for pressure-sensitive tape, medical patch, sticker label, protective film, Adhesive, medical tape, sealing tape, label, plaster and other adhesive products. Tack test.
Features
1. Using Modular Timely Unit, long timing time, accurate timing, small error.
2. Ultra-long timekeeping can reach 9999 hours, 59 minutes and 59 seconds.
3. Equipped with high-end proximity switch, wear resistance, high Sensitivity, longer service life.
4. Strictly in accordance with the standard design of the test plate and test weight, the test plate using laser cutting process, the edge neat and smooth, no burrs, no curling, to ensure the accuracy of the detection data.
5. Three test stations can simultaneously conduct multiple test projects.
6. Equipped with automatic timing, locking, and other functions to ensure the high accuracy of test results.
Principle
The test plate affixed with the sample is hung vertically on the test stand, and the weight of the specified weight is suspended at the lower end. The ability of the adhesive tape to resist pulling off is characterized by the measurement of the displacement of the sample sticking off after a certain period of time, or the time when the sample is completely disengaged.
Applications
Pressure Sensitive Tape, Medical Patch, Sticker Label, Protective Film, Adhesive, Medical Tape, Sealing Tape, Label, Plaster
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. Hang the weight of the specified weight at the lower end.
3. Start Timer Start Timing.
4. Observe and record the amount of displacement or the time for complete dissociation of the sample.
Notice
• Ensure that the edges of the test board are neat and smooth, with no burrs or curling.
• Nominal Mass must meet standard requirements (1000 +/- 1g, optional 200g).
• The load of the pressing roller should be controlled within the range of 2000g +/- 50g.
• Check that the power supply is AC220V 50Hz before use.
• Sensitivity and abrasion of proximity switches are checked regularly.
