Embodiment Construction

[0026] The principle of the present invention is: combine vibration and other field effects with direct sample forming, apply high-frequency vibration and high pressure to the experimental materials, and directly obtain and detect mixed samples through an independent central mold structure, and at the same time, it is equipped with online data collection and analysis. monitoring function. By selecting or designing different flow channel structures of the central mold to conduct mixed shape experiments; selecting or designing the central mold with capillary structure can conduct dynamic rheological experiments; selecting or designing the open central mold can directly obtain microstructure samples. Through the use of central molds of different forms and structures and the adjustment of various parameters related to multiple external fields, the detection of plastic processing morphology, microstructure and rheological properties under the action of vibration induction is realize...

Abstract

The invention discloses plastic vibration processing and sample molding integration test equipment and a method. The equipment comprises a hydraulic power system, a vibration power driving system, a test platform, a piston assembly, a central mould, a visualization device, a controlling system and the like. The equipment and the method combine vibration field quantity with mould sample molding, combine cutting, pressing, vibration and sample processing molding function into a whole, are different from rheological property research limited by polymer of a traditional rheometer, avoid form change of plastic mixture structures when materials in a test cavity are taken out, monitor a microstructure online directly or directly mold and obtain detecting samples. The plastic vibration processing and sample molding integration test equipment and the method can not only achieve the rheological property test of moving state and steady state of the polymer, but also be used for microstructure form research of a plurality of polymer systems under multi-element field quantity and influence rule research between processing performance and technological conditions. The plastic vibration processing and sample molding integration test equipment and the method can be widely applied to industries of material, chemistry, pharmacy, coating, food, building and the like.

Description

technical field [0001] The invention relates to the technical field of plastic melt dynamic mixing and polymer molding processing under the action of multiple field quantities, in particular to an integrated test equipment and method for plastic vibration processing and sample molding. Background technique [0002] The polymer molding process involves complex rheological behavior and morphological structure changes of polymer fluids, and the technological conditions in the process determine the quality of the final use performance of polymer materials. Especially for complex systems such as polymer blending or filling, the development of new experimental instruments with composite functions and the study of the microstructure changes of polymer melts under multiple externally applied fields have a great impact on how to make full use of polymers and polymer blends or polymers. The performance potential of filling system materials and obtaining a uniform and close to ideal st...
