ST106 Initial adhesion tester
The ST106 initial adhesion tester, also known as the initial
adhesion tester or tape adhesion tester, is designed and
manufactured in accordance with the requirements of the new version
of the 2020 Chinese Pharmacopoeia "0952 Adhesion Force
Determination Method". The equipment adopts the inclined rolling
ball method. When a small pressure occurs between the steel ball
and the adhesive surface of the test sample, the adhesive tape,
label, and other products are used to test the initial adhesion of
the sample to the steel ball.
Suitable for conducting initial adhesion testing on
pressure-sensitive tapes, medical patches, self-adhesive labels,
protective films, and other related products. The initial adhesion
tester for labels follows the GB/T 4852 "Test Method for Initial
Adhesion of Pressure Sensitive Adhesive Tape - Rolling Ball Method"
standard, using the principle of inclined rolling ball method to
characterize the initial adhesion performance of adhesive products
by the maximum number of steel balls that can be adhered.
Testing Principles
Roll a steel ball over the adhesive tape adhesive surface placed
flat on an inclined plate, and evaluate its initial viscosity based
on the maximum size of the steel ball that can be adhered to by the
adhesive surface of the specified length; Alternatively, a steel
ball of a specified size can be rolled over an inclined groove and
its initial viscosity can be evaluated by measuring its rolling
distance on the adhesive surface of the adhesive tape on a
horizontal plate.
Using the inclined rolling ball method, the initial adhesion of the
sample is tested by the adhesive tape's adhesion to the steel ball
when there is a brief contact between the adhesive surface of the
steel ball and the pressure-sensitive tape under slight pressure.
Equipment features
lUsing the testing principle of inclined rolling ball method, the
instantaneous adhesion performance of the sample is tested.
lThe test steel balls are designed completely in accordance with
national standards, ensuring high accuracy of test data.
lThe tilt angle of the test can be freely adjusted according to the
user's needs
