Description
Technical field
The present invention relates to aluminium electrolutic capacitor medium-high pressure chemical foil production technical field, more particularly to aluminium electrolutic capacitor
With the method and device of middle raising Waste Acid From Hua Cheng Foil presentation quality.
Background technology
Aluminium electrolutic capacitor with the primary base material of Waste Acid From Hua Cheng Foil be content be 99.99% high-purity aluminium foil, claim light paper tinsel.
Light paper tinsel carries out corrosion reaming to aluminium foil, accumulates to form etched foil to increase aluminium foil surface, etched foil passes through again through electrochemical production flow
Cross under powerful DC electric field effect, pre-processed in the electrolyte of specified temp, one-level is melted into, two level is melted into, three-level
Into production procedures such as, level Four chemical conversion, Pyatyi chemical conversion, high-temperature process, Passivation Treatment, cleaning, drying, the insulating oxide of densification is formed
Film (Al2O3), obtain Waste Acid From Hua Cheng Foil.
Aluminium electrolutic capacitor is mainly come area with the opering characteristic of electric apparatus, mechanical property and appearance characteristics with the quality standard of Waste Acid From Hua Cheng Foil
Point and final conclusion, and high-quality Waste Acid From Hua Cheng Foil has to meet above three technical conditions simultaneously.
Waste Acid From Hua Cheng Foil is very thin, and thickness is micron-sized, and its thickness is usually 1um or so, hole occurs on so thin thickness
Hole or breakage etc., the unit for electrical property parameters of Waste Acid From Hua Cheng Foil can be directly influenced or cause Waste Acid From Hua Cheng Foil to be scrapped.In the production of Waste Acid From Hua Cheng Foil
Cheng Zhong, because the reason for equipment and electrolyte is easiest to produce the appearance qualities such as hole, cut, breach on Waste Acid From Hua Cheng Foil surface.
Therefore, appearance characteristics are highly important quality metrics for Waste Acid From Hua Cheng Foil.
Existing Waste Acid From Hua Cheng Foil production stage mainly includes：Pre-treatment → level Four or Pyatyi chemical conversion → high-temperature process → are melted into again
The steps such as → post processing → cleaning → drying → heating → circulation → transmission → filtering.Fig. 1 show existing Waste Acid From Hua Cheng Foil production
