anodized aluminum paint strip

The anodized aluminum paint strip can put the aluminum strip on the colorful coat, which has an excellent decorative effect. According to the method, it can be divided into spontaneous color, adsorption coloring, and electrolytic coloring. Most of the decolorization problems occur in the adsorption coloring, because Dyes are adsorbed on the surface of the aluminum oxide film holes, and decolorization is inevitable, but if the holes can be sealed, the aluminum oxide film decolorization can be prevented.

Among the many sealing processes, the simplest is hot water sealing, which is low in cost but not effective, and steam sealing is very expensive, and its sealing effect is the most significant. Salt sealing uses NiAc2 plus additives at room temperature or high temperature. , The nickel salt is hydrolyzed and deposited on the surface of the aluminum oxide film pores, preventing the dye molecules from coming out.
 
This type of blocking fluid easily precipitates and becomes invalid, which increases the processing cost. Henan Signe has developed non-bleaching aluminum oxide film technology, which does not decolor during water washing and alcohol scrubbing. It has become the new favorite of anodized aluminum paint strips and opened up the application of aluminum oxide coloring. A new field.
 
With people's demand for different colors of aluminum strips, the dyeing process after anodized colored aluminum strips becomes more and more important. Henan Signi can produce a variety of pleasing high-quality anodized aluminum paint strips.
