Description
Technical field
The present invention relates to dedusting agent category, more particularly, to a kind of new alumilite process closing dedusting agent and its preparation side
Method and technique for applying.
Background technology
Due to easy processing performance and its surface high-corrosion resistance after treatment of aluminum and aluminium alloy, get more and more
Al-alloy products be used in civilian and industrial goods.Anodic oxidation be most widely used as aluminum and aluminum alloy surface one
Kind for the treatment of technology, closing is a kind of anodised post-processing approach, be improve anode oxide film corrosion resistance and pollution resistance must
Need technique, it is also prevented from dyestuff colour fading simultaneously, improves the light resistance of dyeing film, this technology is in 3C Product and interior architecture
Decoration, Furniture fittings gadget, auto parts and components etc. are applied widely it is provided that colourful color.At present
The dyeing film enclosure method being widely used in industry remains the high temperature closing process of acetic acid ni-type, and this is because it has
Fade little, salt corrosion and acidproof solubility property are excellent.But this technique also some defects：1. tank liquor is aging very fast, is also easy to produce sealing of hole
Ash or a powder phenomenon, need to manually wipe or frequently with changing tank liquor, lead to discharging of waste liquid amount big；2. stain resistance performance has much room for improvement,
The requirement of high modern product can not be met；3. oxide-film surface has nickel to deposit, and on wearable product, is easily caused skin allergy.
For the problems referred to above, conventional people take two kinds of methods：(1) addition naphthol sulfonate in enclosed slot, phosphonate,
The grey agent of the suppression such as pyrrolotriazine derivatives or the grey agent of commercially available special suppression, process 1- in the nitric acid or sulfuric acid solution of 10-20% after (2) closing
2 minutes.But two kinds of methods can not remove all of closing ash, particularly the latter, and process time will strictly control, and otherwise can lead
Cause seal quality to decline even surface to grow dim.
