Polymer properties viscosity tester performance characteristics and meet the standard
Intrinsic viscosity is the most commonly used method to describe the viscosity of polymer solutions. Defined as the specific viscosity as the concentration of polymer solution approaches zero. That is, the contribution of a single molecule to the viscosity of solution, is a reflection of the viscosity of polymer properties, its value does not change with concentration. It is often denoted by "η", the usual unit being the deciliter per gram (dL/g). Due to the quantitative relationship between intrinsic viscosity and molecular weight of polymer, the value of η is often used to calculate the relative molecular weight or as a measure of molecular weight. Its value is usually measured by capillary viscometer.
SH112GT automatic characteristic viscosity tester (Shandong Shengtai Instrument Co., Ltd. r & D and production) is in accordance with the People's Republic of China standard GB/T 1632-93 "polymer dilute solution viscosity and characteristic viscosity determination" and GB It is designed and manufactured according to the requirements of "polyethylene terephthalate (PET) resin for bottle". It is suitable for testing the kinematic viscosity, viscosity and characteristic viscosity of oil and polymer dilute solution. It is widely used in petroleum, chemical industry, scientific research, measurement and other departments. Instrument workflow includes constant temperature, detection, calculation, viscosity tube cleaning, drying, printing report sheet automation.
