Initial viscosity testing machine

Test principle: 

The inclined rolling ball method is used to test the initial tack of the sample through the adhesion of the adhesive tape to the steel ball when the steel ball and the adhesive surface of the pressure-sensitive tape sample are in brief contact with a small pressure. Viscosity is a physical property of a fluid substance, which reflects the internal friction between the molecules of the fluid when it is acted upon by 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, a 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, lubricant blending, automatic control of the production process of certain foods and drugs, crude oil pipeline transportation process monitoring, quality inspection of various petroleum products and paints, etc., all require viscosity measurement.
