مبدأ الاختبار

PSTC 6 Rolling Ball Tack Tester adopted the inclined plane rolling ball method and the inclined groove rolling ball method of method B:

الطريقة أ: the adhesion of the adhesive tape to the steel ball when A short contact occurs between the steel ball and the adhesive surface of the pressure-sensitive adhesive tape sample at A small pressure

To test the initial viscosity of the sample.Roll a steel ball across the sticky surface of the adhesive tape on the inclined plate, according to the specified length of the sticky surface

The maximum size of steel ball that can be stuck, and evaluate its initial viscosity.

الطريقة ب: roll a steel ball of specified size through the inclined groove and measure the rolling distance on the sticky surface of the adhesive strip on the horizontal plate to evaluate the initial viscosity.
