Product Introduction:
Initial adhesion tester - This product is designed and manufactured in accordance with GB4852 and is suitable for conducting initial adhesion testing on pressure-sensitive adhesive tapes and other related products.
Working Principle:
Using the inclined rolling ball method, the initial viscosity of the sample is tested by the adhesion of the adhesive tape to the steel ball when a brief contact occurs between the adhesive surface of the steel ball and the pressure-sensitive adhesive tape sample under slight pressure.
Structural composition: mainly composed of inclined plate, ball dispenser, bracket, adjustable horizontal base, and steel balls.
Number of test pieces: 1 group
Operating instructions:
Place the adhesive surface upwards on a test plate tilted at 30 degrees. Take a steel rolling ball of size * and let it fall freely in sequence. Record the ball number that can adhere to the test piece for more than 5 seconds.
