        Corrosion of non-polar electrolytic capacitors: Corrosion generally occurs only in the place where the leakage current is the largest, such as the guide foil strip, the lead wire R, and the rivet. The edge of the anode foil or the first roll. If there is no abnormality in the lead wire, it should only be a problem of aluminum foil or electrolytic paper. It is necessary to unravel the electrolytic paper to observe the aluminum foil or enlarge it.oxe群奧|群奧電子|東莞群奧|樟木頭群奧|東莞電容器|東莞鋁電解電容器|東莞電容器生產廠家|樟木頭鋁電解電容廠家 |東莞市

        If there is no abnormality in the lead wire, it should only be a problem of aluminum foil or electrolytic paper. It is necessary to unravel the electrolytic paper to observe the aluminum foil or enlarge it.
        There will be speckle-like corrosion on the aluminum foil or electrolytic paper. The edge of the aluminum foil is jagged. The leakage current of the product is large. The repeated aging can not be reduced, and the recovery is fast. After use, precipitates will appear, gradually transfer and gather to the lead. At the fever, the charge operates frequently, and the product's lead life is over!
        Non-polar electrolytic capacitor corrosion suppression method:
        1、Improve the purity of the materials used in capacitors and reduce the impurity content;
        2、Reduce the amount of excess electrolyte in the capacitor by means of drying or an open method;
        3、Reduce the moisture in the core and electrolyte;
        4、The high concentration electrolyte is used to reduce the dissolved oxygen content and increase the flashover voltage of the electrolyte;
        5、A corrosion inhibitor is used to protect the oxide film or form a protective film.
