The chemical conversion manufacturing process of anode foils.
Background technique
Currently, low-voltage anodic foil for aluminum electrolytic capacitor, in formation process, chemical conversion tank liquor is exposed in air, electrolytic bath
Liquid temperature causes tank liquor surface liquid to be easy to volatilize between 70-90 DEG C, takes away a large amount of tank liquors and heat, leads to tank liquor surface
There is deviations inside temperature and ingredient and tank liquor, and fluctuate at any time, lead to the inhomogeneities of chemical conversion treatment, are embodied in production
Moral character can go up the use that subsequent capacitance device producer is influenced as front and back aberrations in property.Meanwhile ammonium adipate has been taken away in tank liquor evaporation
And amount of heat, also result in the waste of chemicals and the energy.
Summary of the invention
It is an object of the invention to overcome the above shortcoming, the evaporation situation of chemical conversion tank liquor is improved, is used
Two or more diameters PPH floating ball, uniformly dispersing inhibit the evaporation of chemical conversion tank liquor on tank liquor surface.It is inclined to improve Waste Acid From Hua Cheng Foil performance
Difference, while reducing the waste of chemicals and the energy.
The purpose of the present invention is achieved through the following technical solutions：A kind of improvement aluminium electrolutic capacitor is inclined with Waste Acid From Hua Cheng Foil performance
The method of difference, steps are as follows：Using the PPH floating ball of two or more diameters, it is evenly distributed in aluminium electrolutic capacitor electrolytic bath
On liquid liquid level, small diameter floating ball fills the gap between larger diameter floating ball, guarantees that 90% of liquid level or more is covered by floating ball,
Inhibit the evaporation of chemical conversion tank liquor at high temperature, improves chemical conversion tank liquor temperature and ingredient stability, improve aluminium electrolutic capacitor
At foil head and the tail deviation.
Preferably, floating ball has eccentric structure, and the deviation of gravity center centre of sphere generates phase when electrode foil is in contact with floating ball
To rolling, guarantee that floating ball will not generate scratch to aluminium foil, while floating ball will not overturn rolling, the tank liquor that will not will be adhered under floating ball
It is exposed in upper air, inhibits tank liquor evaporation.
Preferably, floating ball diameter is two kinds, respectively 10 cm and φ 2cm of φ.
Preferably, floating ball diameter is three kinds, respectively 10 4 cm and φ 1cm of cm, φ of φ.
In conclusion the present invention has the following advantages that：Using two or more diameters PPH floating ball, uniformly dispersing is in tank liquor
Surface inhibits the evaporation of chemical conversion tank liquor.Improve Waste Acid From Hua Cheng Foil aberrations in property, while reducing the waste of chemicals and the energy.
