(1) Aluminum alloy aluminum and other pieces of material impact. Usually high purity aluminum, Al-Mg and Al-Mn after closing 金经阳 anodic oxidation, staining the best performance can be dyed various colors. The amount of silicon or copper alloy high quality aluminum and aluminum alloy aluminum tee Which is good, only dyed dark black color to drab. (2) the quality of the oxide film. Quality oxide film mainly refers to the film thickness, porosity and transparency indicators. As the film having a sufficient thickness (10um above) and porosity and maximum transparency, optimum dyeing quality can be obtained. Staining solution temperature. Stained with cold dye (room temperature) and thermal dye two kinds. Cold-dyed tee long supply aluminum prices, but the uniformity of the colors is easy to control. Thermal dye aluminum tee time is short supply manufacturers, but the tone was difficult to control. Thermal dye temperature control in 40 ~ 60 ℃, such as high temperature (80-90 ℃), tend to make the dye molecule is not fully penetrate deep into the membrane pores already closed, thereby greatly reducing fastness and easy to make surface Flooding.
