技术领域technical field
本实用新型属于化学实验室测试仪器技术领域，尤其涉及一种凝胶时间测定装置。The utility model belongs to the technical field of chemical laboratory testing instruments, in particular to a gel time measuring device.
背景技术Background technique
溶胶或溶液中的胶体粒子或高分子在一定条件下互相连接，形成空间网状结构，结构空隙中充满了作为分散介质的液体，这样一种特殊的分散体系称做凝胶。凝胶是温度升高到接近聚合物分解温度时不熔融，且在各种溶剂中不溶解的状态。聚合物在一定温度下，形成凝胶是的反应程度称为凝胶点，也称凝胶时间。凝胶时间是树脂、复合材料、弹性体、胶黏剂、密封胶等物质的重要工艺指标。目前，凝胶时间的测定方法多使用凝胶板或凝胶测定仪，凝胶测定仪不适合检测固体材料，且不能测定完全固化凝胶；凝胶板测定受温度影响很大，而最常采用的电加热方式加热温度不稳定，保持温度恒定比较困难，导致测试结果不准确，也存在安全隐患。The colloidal particles or polymers in the sol or solution are connected to each other under certain conditions to form a spatial network structure, and the structural voids are filled with liquid as a dispersion medium. Such a special dispersion system is called a gel. Gel is a state in which it does not melt when the temperature is raised to close to the decomposition temperature of the polymer, and is insoluble in various solvents. The degree of reaction of the polymer to form a gel at a certain temperature is called the gel point, also known as the gel time. Gel time is an important process index for resins, composite materials, elastomers, adhesives, sealants and other substances. At present, the determination method of gel time mostly uses gel plate or gel tester, and gel tester is not suitable for detecting solid materials, and cannot measure fully cured gel; gel plate measurement is greatly affected by temperature, and the most common The heating temperature adopted by the electric heating method is unstable, and it is difficult to keep the temperature constant, resulting in inaccurate test results and potential safety hazards.
因此，需要设计一种凝胶时间测定装置，测试过程中能保证测试温度恒定，并且测试温度有较宽的可调节范围以适应不同的测试样品。Therefore, it is necessary to design a gel time measuring device, which can ensure a constant test temperature during the test, and the test temperature has a wide adjustable range to adapt to different test samples.
