Abstract

A rheological in-situ online test system integrating scattering and microscopy is disclosed. Aimed at the problems that a general capillary rheometer cannot realize in-situ online observation and a microscopic rheological test system and a light scattering rheological test system cannot realize intuitive observation of sample microstructure, the invention designs an integrated flat capillary rheological in-situ online test system capable of performing laser scattering and microscopic observation while performing rheological performance testing. A stable shear flow field and rheological parameters related with macroscopic properties of a material can be provided through a rheological system, the in-situ internal microscopic structure of the polymer material can be detected and observed through an optical technology, a microimaging system, a laser scattering system and a capillary rheological system are organically combined, and the relationship between the microstructure and the macroscopic properties of the material can be researched more conveniently. The rheological in-situ online test system is suitable for macromolecular polymer processing application labs.

Description

technical field [0001] The invention relates to the field of testing the rheological properties of polymer materials, in particular to an in-situ online testing system for rheological properties, in particular to a rheological in-situ online testing system integrating scattering and microscopy. Background technique [0002] Rheology is the elastic, plastic and viscous deformation behavior of polymer materials under stress. The rheological data of polymer materials is the most basic process parameter in its molding process. The selection and use of raw materials and the optimal molding process The determination of conditions, the design of molding equipment and molds, and the improvement of product quality all play an important role. At present, polymer materials are developing toward functionalization and specialization, and it is the key to the development of new materials to solve the problem of processing performance with a quick method and a minimum of samples.
