Description
技术领域technical field
本发明属于流体测试或测量装置技术领域，具体涉及到一种流变仪的零部件。The invention belongs to the technical field of fluid testing or measuring devices, and in particular relates to a component of a rheometer.
背景技术Background technique
流变仪用于测定凝胶、聚合物熔体，聚合物溶液、悬浮液、乳液、涂料、油墨和食品等物质流变性能的仪器。通过流变学测量，可获得材料动态粘弹特性、动态屈服值、粘温相应特性、触变性、蠕变恢复等流变学性能，在材料或流体性能调控等方面发挥着十分重要的作用。通常，旋转型流变仪使用的夹具包括平行板、椎板、同心套筒、压力同心套筒、桨式转子[Gebhard Schramm.A Practical Approach to Rheology and Rheometry,1994.]。然而，在实际测量过程中，目前的旋转流变仪测试系统无法实现部分材料或流体的原位制备与精确测量，包括：(1)针对只有在密封超声作用方可形成的结构性流体或软固体物质，目前流变仪所有的夹具均无法实现原位制备，所有的夹具系统只可可实现加热，无法实现超声原位制备；(2)针对只适合平行板或椎板测量的结构性流体或软固体物质，如果当从其他所盛容器中移出时极易破损或严重破坏其原始结构，放置无法恢复流体或材料的自身结构，那么现有的平行板夹具或椎板夹具系统并不满足原位制备的功能；(3)针对只适合平行板或椎板测量的挥发性极强的结构性流体或软固体物质，如果制备过程必须在严格密封容器中进行时，现有平行板夹具或椎板夹具系统并不具备原位密封制备的功能；(4)针对只适合平行板或椎板测量的结构性流体或软固体物质，现有的平行板夹具或椎板夹具系统在具备不满足原位制备的功能的基础上，也无法实现实时在线跟踪结构流体形成过程的超分子作用方式。Rheometer is an instrument used to measure the rheological properties of gels, polymer melts, polymer solutions, suspensions, emulsions, coatings, inks and foods. Through rheological measurement, the rheological properties such as dynamic viscoelastic properties, dynamic yield value, viscosity-temperature response properties, thixotropy, and creep recovery of materials can be obtained, which play a very important role in the regulation of material or fluid properties. Generally, fixtures used in rotational rheometers include parallel plates, vertebral plates, concentric sleeves, pressure concentric sleeves, and paddle rotors [Gebhard Schramm. A Practical Approach to Rheology and Rheometry, 1994.]. However, in the actual measurement process, the current rotational rheometer test system cannot realize the in-situ preparation and accurate measurement of some materials or fluids, including: (1) for structural fluids or soft materials that can only be formed under the action of sealing ultrasound For solid substances, all fixtures of rheometers cannot be prepared in situ at present, and all fixture systems can only be heated, and ultrasonic in situ preparation cannot be realized; (2) For structural fluids or For soft solid substances, if they are easily damaged or severely damaged their original structure when removed from other containers, and cannot restore the fluid or material's own structure when placed, then the existing parallel plate clamp or laminar clamp system does not meet the original requirements. (3) For highly volatile structural fluids or soft solid substances that are only suitable for parallel plate or vertebral plate measurement, if the preparation process must be carried out in a strictly sealed container, the existing parallel plate fixture or vertebral plate The plate fixture system does not have the function of in-situ sealing preparation; (4) For the structural fluid or soft solid matter that is only suitable for parallel plate or lamina measurement, the existing parallel plate fixture or lamina fixture system does not meet the original requirements. On the basis of the function of bit preparation, it is also impossible to realize the real-time online tracking of the supramolecular interaction mode of the formation process of the structured fluid.
