Description
Technical field
It is particularly a kind of using seven grades of mesohigh electrodes of different hair engaging aperture conditions the present invention relates to the manufacture method of electrode foil
Foil making method.
Background technology
Since reform and opening-up, national economy rapid growth, " scientific and technical innovation, autonomous innovation " has turned into current domestic industry hair
The main flow of exhibition, China's electronic industry is developed rapidly, especially the urgency in the machine product such as communication products, computer, household electrical appliances market
Play expands, and the development to aluminum electric pole foil industry has play a part of to add fuel to the flames.Simultaneously because the miniaturization of aluminium electrolutic capacitor, height
Performance-based, chip type requirement it is more and more urgent, the manufacturing industry to electrode foil it is also proposed technology and quality requirement higher.Electricity
Pole paper tinsel is the key raw material of aluminium electrolutic capacitor manufacture, and the quality of electrode foil will directly influence aluminium electrolutic capacitor
Functionality, quality and appealing design is poor.The conventional corrosion technology flow of currently manufactured electrode foil is pre-treatment-washing-Chemical cleaning-washing-pure water
Cleaning-dry, is main corrosive liquid with hydrochloric acid sulfuric acid or nitric acid, using direct current hair engaging aperture for several times, each corrosive liquid and electricity
Stream, temperature all same.Such as existing five-stage manufacturing method：Aluminium foil that first learn from else's experience excessive erosion, that purity is 99.99%, 90~
Impregnated 5~10 minutes in 100 DEG C of pure water, the water-soluble of 0.1~8% citric acid and 0.1~5% citrate is placed in after taking-up
It is then that one-level is melted into 8~15 points under conditions of 20mA/ (cm) 2, voltage is 140V in 70~95 DEG C, current density in liquid
Clock；Aluminium foil after one-level is melted into again is rinsed after taking out with water, then is placed in 0.1~5% azelaic acid and 0.1~5% nonyl two

95 DEG C, current density be 20mA/ (cm) 2, voltage be 580V under conditions of, level Four be melted into 8~15 minutes；After level Four is melted into
Aluminium foil is placed in the aqueous solution of 0.1~3% azelaic acid and 0.1~3% azelate again, in 70~95 DEG C, current density
Be 20mA/ (cm) 2, voltage be 620V under conditions of, Pyatyi be melted into 8~15 minutes；Aluminium foil after Pyatyi is melted into is from electrolyte
Taken out in groove, carry out 500 DEG C of high-temperature heat treatment 3~4 minutes；0.1~3% azelaic acid and 0.1~3% nonyl two are placed in again
It is under conditions of 20mA/ (cm) 2, voltage is 620V, to be melted into 8~15 points in 70~95 DEG C, current density in the aqueous solution of hydrochlorate
Clock；Then processed with temperature as 50~80 DEG C in 1~8% phosphoric acid solution；Be placed in again 0.1~3% azelaic acid and
It is then that 20mA/ (cm) 2, voltage is 620V's in 70~95 DEG C, current density in the aqueous solution of 0.1~3% azelate
Under the conditions of, it is melted into 8~15 minutes；Finally take out, dry.The manufacturing process of electrode foil for aluminum electrolytic capacitors is also aluminium foil surface
The process that hole produces and grows, in generation and production process, the length change in aperture and hole can be because of the structure shape in hole itself in hole
State and it is different, and in existing manufacturing technology, hair engaging aperture condition is single, it is impossible to fully meet hole different phase pair in growth course
Required in the difference of etching condition, cause pore size distribution uneven or the problem that hole merges and reduces effective hole number occurs.In order to
