Problems solved by technology

[0003] Due to the Karl Fischer electrolyte in the electrolytic cell of the trace moisture meter during the test process, a certain amount of trace acid gas is generated, causing the used vacuum grease to become invalid and hard after a period of time, so that the negative and positive electrodes, drying column and The electrolytic cell is stuck and cannot be taken out, so it is impossible to replace the invalid Karl Fischer electrolyte and the desiccant of the drying column

Abstract

The invention discloses a method for sealing an electrolytic cell of a micro moisture analyzer by using vacuum grease, and belongs to the field of electrolytic cell sealing. The sealing grease for theelectrolytic cell is prepared through mixing of existing vacuum grease and Vaseline at a mass ratio of 5:1. The sealing grease for the electrolytic cell is prepared through mixing of the existing vacuum grease and Vaseline, so that the current problems of failure and hardening of the grease after use of a period are solved effectively, and the situation that the electrolytic cell cannot be takenout due to adhesion of the electrolytic cell with a cathode electrode, an anode electrode and a drying column when the electrolytic cell needs to be replaced can be avoided effectively, so that replacement of an electrolyte is more convenient and quicker.

Description

technical field [0001] The invention belongs to the technical field of electrolytic cell sealing, and in particular relates to a sealing grease for an electrolytic cell and a sealing method thereof. Background technique [0002] Trace moisture analyzer is also known as Karl Fischer moisture analyzer, and there are moisture analyzers, moisture meters, moisture meters, moisture detectors, moisture meters, and moisture analyzers in the same category. The connection between the electrolytic cell of the trace moisture analyzer and the two electrodes and the two drying columns needs to be sealed and fixed with sealant to prevent the moisture in the air from entering. [0003] Due to the Karl Fischer electrolyte in the electrolytic cell of the trace moisture meter during the test process, a certain amount of trace acid gas is generated, causing the used vacuum grease to become invalid and hard after a period of time, so that the negative and positive electrodes, drying column and ...
