Capacitor impregnation process

Abstract

The invention provides a capacitor impregnation process, which comprises the steps of putting a capacitor core to be impregnated in an impregnation tank, then performing vacuum pumping, applying negative pressure after vacuum pumping, impregnating the capacitor core and relieving the pressure after impregnation; repetitively performing vacuum pumping, pressure application and two times of impregnation to obtain the impregnated capacitor core. The capacitor impregnation process has the advantages that the process is simple and convenient to operate, the impregnation time can be greatly shortened, the impregnation effect of the capacitor core is good, only 5-8 hours are needed by adopting the process while 15-20 hours are needed by adopting conventional processes, the impregnation time is greatly shortened, the production efficiency is improved, the product quality is remarkably improved and the electrolyte is utilized to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of capacitor manufacturing, in particular to a capacitor core impregnation process. Background technique [0002] The core impregnation of existing capacitors is mostly directly put the core package into the container containing the impregnation liquid and soak for a long time, so that the impregnation liquid penetrates into the positive foil, negative foil, and paper. The production efficiency of this method is low. , the soaking time is long, the impregnation effect is not ideal, and the production cost is high; and the dried liquid cannot be reused, which will cause certain pollution to the environment; there is another way to use spot injection, that is, inject the electrolyte into the core with a special syringe , this mode has low production efficiency and high labor intensity. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and...
