Application of High Temperature Viscometer in Bitumen Viscosity measurement

The asphalt high-temperature viscometer uses a rotor to measure the viscosity characteristics of the melt at high temperature, which requires the instrument to have the characteristics of temperature control and viscosity measurement.

Viscosity is a physical characteristic of a fluid substance, which reflects the internal friction between molecules when the fluid is subjected to an external force. 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 application of asphalt high-temperature viscometer can 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.

The main application fields of asphalt high-temperature viscometer include: optical glass, metallic glass, ceramics, metal, slag, mold slag, coal gasification, TFT glass substrate, coal gasification and other high-temperature melt viscosity measurement. The torque generated by the continuous rotation of the spindle is used to measure the viscosity value. The torque is proportional to the resistance caused by the viscous drag of the spindle immersed in the sample, and thus proportional to the viscosity.

Asphalt high-temperature viscometer is widely used, easy to operate, and stable in performance. The Flow Cup body and outlet are made of corrosion-resistant materials. It is mainly used to measure the kinematic viscosity of Newtonian or near-Newtonian fluid (below 150 seconds), and it can also be used for comparative measurement as required. Principle and structure The viscometer is made of brass, with a capacity of 100ml, and its standard conforms to GB/T1723-93. This product is suitable for measuring paint with an outflow time of less than 150S.
