Embodiment Construction

[0025] In order to better understand the present invention, the present invention will be further described in detail below in conjunction with embodiments, but the scope of protection claimed by the present invention is not limited to the scope indicated by the embodiments.

[0026] This embodiment uses the tomographic image measurement system of the dynamic extrusion process to measure the shape of the molten material in the extrusion process.

[0027] (1) Acquisition of tomographic images in closed molding spaces

[0028] As shown in Figure 1, the tomographic image measurement system for the shape of the molten material in a closed state is mainly composed of a ray source 5, a photodetector 1, a data acquisition device 2, a computer 3, a mechanical scanning platform 6, a motion control device 4, etc. The objects are the molding equipment 7 and the molten material 8 in a closed high pressure and medium temperature. Among them, the molding equipment 7 uses an extruder, which is m...

Description

Technical field [0001] The invention relates to a non-contact and on-line measurement method for the shape of molten materials in a molding device, in particular to a tomographic image measurement method for the shape of molten materials in a closed state. Background technique [0002] Understanding the detailed and complete morphological changes and thermal history factors that affect the morphology of molten polymers during processing can not only guide people to focus on the order and structure of crystalline and amorphous polymers under dynamic and static (equilibrium) conditions. The change of "and shape", and more practical significance is that it can be used as a theoretical basis for controlling polymer structure and improving the quality of polymer molded products. So far, there are direct observation methods, flow birefringence method, laser Doppler velocimetry, electron microscope micro-area, X-ray diffraction, laser speckle photography, and visualization technology fo...
