Description

Technical field:

[0001] The utility model relates to a gel temperature measuring instrument. Background technology:

[0002] Under certain conditions, the colloidal particles or polymers in the sol or solution are interconnected to form a spatial network structure. The structural gaps are filled with liquid as the dispersion medium. Such a special dispersion system is called a gel. Generally, gels have no fluidity and often contain a large amount of liquid inside. They can be divided into elastic gels and brittle gels. When the elastic gel loses the dispersion medium, its volume shrinks significantly, and when it reabsorbs the dispersion medium, its volume expands again.

[0003] The gel forms a three-dimensional network structure. In the network structure, the medium is surrounded in the middle of the mesh and cannot flow freely, thus forming a semi-solid. Since the polymer compounds or linear colloid particles that constitute the network still have a certain flexibility, the entire gel also has a certain elasticity. Furthermore, the formation of the gel is first determined by the polymers or colloid particles with linear structures, and secondly is related to external factors such as concentration, temperature, and time.

[0004] The application of gel is very extensive and can be popularized and applied in key links in various usage scenarios; in actual application, the regulation of real-time temperature of gel is an important control indicator, and the specific form of gel is judged according to the temperature parameters obtained by detection; since the existing gel temperature detection heating method is mostly water bath heating, more water vapor will be generated, affecting the overall recognition accuracy of the instrument, and the heating process of existing instruments is mostly continuous, resulting in the gel heating too fast, which is not convenient for detection and measurement; in addition, some gels become transparent gels within a specific temperature point, and turbid solutions outside this temperature point; therefore, the utility model can use the temperature and the transmittance change of the gel solution to detect the specific temperature point.
