RH-20 Rheometer

Ⅰ. Introduction of Shanghai BosinTech RH-20 Rheometer 

Key words: Rheometer; Material Property Analyzer; Rotational Rheometer; Torque Rheometer

Rheometers are instruments used to determine the rheological properties of polymer melts, polymer solutions, suspensions, emulsions, coatings, inks, and food products. Divided into rotational rheometer, capillary rheometer, torque rheometer and interface rheometer. Shanghai BosinTech RH-20 rheometer can be used to determine the rheological properties of polymer melts, polymer solutions, suspensions, emulsions, coatings, inks and foods. Shanghai BosinTech RH-20 rheometer is similar to HAAK rheometer, TA rheometer, Anton Paar rheometer, brookfile rheometer, etc., and can be used to observe the internal structure window of polymer materials. The molecular weight and molecular weight distribution of polymer materials can be characterized by the response of different scales of molecular chains in polymer materials, such as plastics, rubbers, and resins. It can quickly, easily and effectively perform quality testing and quality control of raw materials, intermediate products and final products.

Rheological performance testing builds a bridge between the molecular weight, molecular weight distribution, degree of branching and processing properties of polymers. So rheometers provide a direct link to assist users in raw material inspection, process design and product performance prediction.

Ⅲ. Main functions and application scope of Shanghai BosinTech RH-20 rheometer

Shanghai BosinTech RH-20 rheometer can be used in a variety of detections in food (liquid, solid, gel, dispersion), fermentation, chemical, pharmaceutical, textile, agricultural and other industries. It is suitable for macromolecular affinity such as protein and polysaccharide. Determination of rheological properties of hydrocolloids, including rheological studies of fluids, soft solids, polymers, gels and dispersions of any viscosity. Since the rheological properties of food materials have an important relationship with the texture stability of food and processing process design, etc., so through the study of rheological properties of food and chemical materials, we can understand the composition, internal structure and molecular morphology of food and chemical materials, which can provide convenience and basis for product formulation, processing process, equipment selection and quality testing, etc. Through rheometer testing, quality monitoring of food and medicine, food R&D and food engineering design can be carried out.
