Scope of application: 

This testing machine is mainly used for the initial adhesion test of pressure-sensitive tape and related products such as pressure-sensitive adhesive tape products. It is easy to operate and highly practical. It is suitable for the initial adhesion test of pressure-sensitive tapes, medical patches, self-adhesive labels, protective films and other related products.

Experimental principle:

The principle of the test is to test the initial adhesion of the sample by the adhesion of the adhesive tape to the steel ball when the steel ball and the sticky surface of the pressure-sensitive tape sample are briefly contacted with a small pressure by using the inclined-plane rolling method. Viscosity is a physical characteristic of fluid substances, which reflects the internal friction between molecules when the fluid is subjected to external forces. The viscosity of a substance is closely related to its chemical composition. In industrial production and scientific research, the composition or quality of substances is often monitored by measuring viscosity. For example, in the production process of polymer materials, the viscometer can be used to monitor the viscosity of the synthesis reaction product and automatically control the reaction end point. Others such as petroleum cracking, lubricating oil blending, automatic control of the production process of certain foods and drugs, monitoring of crude oil pipeline transportation process, quality inspection of various petroleum products and paints, etc., all need viscosity measurement.
