Production method of calcium sulphate dehydrate and production device thereof

Номер: CN103693670A
Автор: RAN LIANG, ZENG SENSHI, LUO XIANGJUN
Принадлежит:

The invention relates to a production method and device of calcium sulphate dehydrate. The method comprises the following steps: mixing an acid solution containing waste sulfuric acid with alkaline liquor containing calcium hydroxide, and adding to a neutralization pond; carrying out neutralization crystallization under full agitation of a propeller; controlling the concentration of the sulfuric acid added to the acid solution and the concentration of the calcium hydroxide added to the alkaline liquor within the range of 0.05-0.4mol/L; simultaneously, controlling the pH value of the mixed solution in the neutralization pond to be neutral, and controlling the detention pond time of the mixed solution in the neutralization pond for 20 minutes to 2 hours; outputting the mixed solution after neutralization crystallization through a liquid outlet formed at the lower part of the rear section of the neutralization tank as filtered water. By adopting the production method, flake crystal which is ...

Mixed production method for electrolytic capacitor fine aluminum cathode foil corrosion and anodic oxidation

Номер: CN0101425378A
Автор: ZENG SENSHI, SENSHI ZENG
Принадлежит:

The invention discloses a mixed manufacture method of pure aluminum cathode foil etching and anodic oxidation for electrolytic capacitors. The pure anode aluminum foil with over 99.4 percent of Al content is directly subjected to anodic oxidation treatment after being etched by alternating current, and a layer of corrosion alumina film is immediately formed on the etching surface. The purpose is to prevent the capacity of the cathodic etched-foil from decreasing before the anodic oxidation, and instantaneously keep the capacity of the cathode foil stable; the etching and the anodic oxidation are carried out on the same machine in a linkage way so as to save a great deal of cost for large-scale production.

Producing process for electrolysis capacitor high temperature resistant alloy aluminum cathode foil

Номер: CN0101425385A
Автор: ZENG SENSHI, SENSHI ZENG
Принадлежит:

The invention belongs to a preparation technology of a high-temperature resistant alloy aluminum cathode foil for capacitors. The adopted technical scheme comprises: pretreatment, pure chemical etching, first mid-treatment, second mid-treatment, third mid-treatment, stabilization treatment and washing treatments among the steps. The invention adds the three-level mid-treatment, adopts sufficient cleaning and a multi-level film layer covering method to enhance the hydration resistance of the cathode foil and prevent the disadvantages brought by Cu, Fe and other impurities; the capacity of the cathode foil does not change after boiling water treatment of deionized water for ten hours, thereby the leakage current is prevented from increasing, and the capacity does not change especially under high temperature treatment for a long time, thereby the service life of the capacitors is prolonged.
