ASTM D2979 Self-adhesive ring initial adhesion tester Probe type initial adhesion testing machine

Principle introduction

Make a standard area metal probe contact with the adhesive with a load of 100 grams for 1 second, measure the force of the probe from the adhesive, and take the average of five times. The instrument is the product of the connection of electronic skills and mechanical transmission. It adopts electromechanical integration design and is mainly composed of force sensor, transmitter, microprocessor, load driving mechanism, computer and color inkjet printer.

Scope of application

It is suitable for the initial adhesive force test of the probe for adhesive tape, protective film, label and other products to judge the initial adhesive mark. Before the instrument came out, the initial adhesive force test was usually determined by the rolling ball method. The rolling ball method is a simple and low-cost test process, but the experimental results are not comparable with other types of initial adhesive tests. High viscosity adhesives do not always get good initial viscosity results. Due to the limitations of the initial viscosity determination by the rolling ball method, compared with the traditional rolling ball method (GB/T4852-2002), the test results were obtained

Needle initial adhesion tester It is easy to measure the viscosity of the pressure adhesive. Good repeatability of test data, avoiding temperature,

The influence of test conditions and human factors on test results.
