Preparation method of oxidation sensor with built-in large cavity
The invention relates to the technical field of oxidation sensors, and discloses a preparation method of an oxidation sensor with a built-in large cavity, the method optimizes a rubber material and a lamination mode, the rubber material selects pvb rubber particles with a particle size of 1-3 [mu] m, and the pvb rubber particles are uniformly dispersed in a volatile organic solvent to prepare a second-stage rubber material; the precise sizing effect can be achieved by controlling the particle size and content of the pvb colloidal particles, the colloidal particles can be uniformly sprayed on the composite surface of the green ceramic chip with a small area, the colloidal particles can form a tiny film structure between the green ceramic chips after being subjected to warm water isostatic pressing lamination to provide adhesive force for the green ceramic chips, and the tiny film structure can form an adhesive force between the green ceramic chips when a block is sintered. The membrane structure can be filled by the volume change of the heated and expanded ceramic chip, so that the green ceramic chip is contacted and sintered into a whole, and the cracking rate of the oxidation sensor can be obviously reduced while the green blank block is not structurally collapsed.
本发明涉及氧化传感器技术领域，公开了一种内置大空腔氧化传感器的制备方法，该方法对胶料和叠层合压的方式进行了优化，胶料本发明选择了粒径为1~3μm的pvb胶粒并将其均匀分散在可挥发性有机溶剂中制成二段胶料，通过控制pvb胶粒的粒径和含量能够达成精准施胶的效果，能够在面积较小的生瓷片复合面上均匀的喷上胶粒，这些胶粒再经过温水等静压叠合后会在生瓷片之间形成微小的膜结构对生瓷片提供粘合力，微小的膜结构在巴块烧结时，陶瓷片受热膨胀的体积变化会将膜结构填合从而使生瓷片接触并被烧结成一个整体，保证生胚巴块不会结构崩塌的同时又可以显著降低氧化传感器的开裂率。
