Problems solved by technology

The above-mentioned instruments all have great limitations. For example, the shear cell is a flat plate shear. The reason is that these foreign scientists have different research priorities, which leads to the singleness of the shear cell and detection system in the design of the instrument. In addition, the above four instruments Basically fixed, it is difficult to install it on the synchrotron radiation window

Embodiment Construction

[0010] Embodiments of the present invention are described as follows in conjunction with accompanying drawing 1 and 2:

[0011] Figure 1 is a cross-sectional view of a shear cell,

[0012] Figure 2 is a schematic diagram of the working principle of the shear cell and the laser system.

[0013] The shear cell adopts the geometry of quartz cone and plate, and the relative rotation occurs under the control of the micro-step motor, so as to produce a visible shear field with a strictly controllable shear rate and other measures. In the actual use process, the following systems can be used to detect the properties of polymers under the action of shear field:

[0014] Laser Light Scattering System: Using He-Ne laser as the light source, the emitted laser light enters the shearing cell through optical elements such as attenuation plates, and the scattered light is converged to the CCD through two lenses, and Fourier images are recorded.

[0015] Phase-contrast microscope system: th...

Abstract

The invention belongs to portable temperature control cone board shearing pool; it is a device for research the crystallization and separation behavior of object combining with micropolariscope, phase difference microscope, fluorescent microscope, laser scattering and X ray scattering technologies under even shearing field, the research with the device to polymer system can provide reliable gist and theory instructions for designing of polymer material.

Description

technical field [0001] The invention belongs to a portable temperature-controlled cone-plate shear pool. Background technique [0002] As we all know, the total annual production volume of today's polymer materials has surpassed that of steel and has gradually become the main body of the three general-purpose materials. Polymer materials must be processed and shaped before they can be used, and the processing process will change the chain conformation, condensed state structure and molecular structure of the polymer material, which will fundamentally change the final use performance of the material. We know that in the process of processing, in addition to factors such as processing temperature and pressure, the shear force or shear rate of the screw plays the most direct role in the end-use performance of polymer materials, mainly reflected in the shear force or shear rate. The effect of shear rate on the rheological behavior, phase behavior and morphological structure of ...
