Description
Translated fromChinese技术领域technical field
本发明涉及检测装置技术领域，尤其涉及一种与低场核磁共振谱仪联用的模块化同步检测装置。The invention relates to the technical field of detection devices, in particular to a modular synchronous detection device used in conjunction with a low-field nuclear magnetic resonance spectrometer.
背景技术Background technique
高分子材料其成型及服役过程当中都会受到外界力场的作用，例如注塑、挤出、吹塑成型等成型加工过程中会受到流动场的作用，而在服役的过程中往往作为承力结构件同样也会受到力场的作用。在力场的作用下，高分子材料微观结构和动力学将发生快速的改变，而微观结构和动力学直接影响高分子材料的服役性能。为了提高高分子材料的服役性能，需要认清高分子材料微观结构和动力学演变过程。Polymer materials will be affected by external force fields during their molding and service processes. For example, injection molding, extrusion, blow molding and other molding processes will be affected by flow fields, and they are often used as load-bearing structural parts during service. Also affected by the force field. Under the action of the force field, the microstructure and dynamics of polymer materials will change rapidly, and the microstructure and dynamics directly affect the service performance of polymer materials. In order to improve the service performance of polymer materials, it is necessary to understand the microstructure and dynamic evolution process of polymer materials.
目前用于高分子材料服役过程中的原位检测方法和装置主要集中在X射线散射、红外/拉曼光谱及显微镜等表征领域。然而，高分子材料加工及服役过程中的工况往往是复杂的，在外力场作用下存在单轴拉伸、多轴拉伸、压缩及剪切等多种形变模式过程。此外，对于一些特殊功能薄膜，例如可以作为偏光片使用的PVA薄膜，在溶液流延成型加工过程中需要分别在硼酸溶液及碘溶液当中进行浸润和碘染。为了更贴近高分子材料实际工业加工过程，要求原位检测设备具有不同工况条件下的检测高分子材料结构和动力学演变过程信息。因此，在高分子材料加工及服役过程中，检测高分子材料微观结构和动力学演变过程难度很大。At present, the in-situ detection methods and devices used in the service process of polymer materials are mainly concentrated in the fields of X-ray scattering, infrared/Raman spectroscopy and microscopy. However, the working conditions during the processing and service of polymer materials are often complex, and there are various deformation modes such as uniaxial tension, multiaxial tension, compression, and shear under the action of an external force field. In addition, for some special functional films, such as PVA films that can be used as polarizers, infiltration and iodine dyeing in boric acid solution and iodine solution are required during the solution casting process. In order to get closer to the actual industrial processing of polymer materials, in-situ detection equipment is required to have information on the structure and dynamic evolution of polymer materials under different working conditions. Therefore, it is very difficult to detect the microstructure and dynamic evolution process of polymer materials during the processing and service of polymer materials.
