国标/T 4851-2014 Test Method for stickiness of Pressure-sensitive adhesive Tapes

ASTM D3654-2019 Standard Test Method for Shear Viscosity of Pressure-sensitive adhesive Tapes

JIS Z0237-2000 Test Method for pressure-sensitive adhesive tapes and Pressure-sensitive adhesive sheets

仪器特点

1.The test plate and test weight are designed in strict accordance with the standard to ensure the accuracy of test data.

2.More than test stations can carry out multiple groups of test items simultaneously.

3.Automatic timing, locking and other functions further ensure high accuracy of test results.

介绍

Under the condition of constant load, 温度 (23+-1)C and relative humidity (50+-5)%, the stickiness of adhesive tape to standard steel plate was measured by the failure time of adhesive tape.Stickiness to standard steel plate: a adhesive tape is pasted to a standard steel plate at a controlled rolling rate.The steel plate is installed vertically or horizontally, and a standard weight is hung at the free end of the adhesive tape to determine the time of adhesive failure.

笔记: The vertical method is used for the measurement of stickiness with failure time less than 4h/the horizontal method is used for the measurement of stickiness with failure time greater than 4h

适用范围

It is suitable for adhesive tape, protective film, 标签, plaster and other products to carry out stickiness test. The resistance of adhesive samples to pull-off can be represented by the displacement of adhesive samples or the time when the samples are completely detached after a certain period of time.
