(3) staining solution concentration. Ze dyed concentration relationship is: a light-colored dye concentration may be lower aluminum links, stained dark, concentration can be higher. Which is usually cheaper aluminum tee, dyed very light colors 0.1-0.39g / L, stained tinge of 1g / L, dyed a deep shade of 3-5g / L, stained strong colors for 10-15g / L concentration is too high could easily lead to uneven color or good quality aluminum floating color phenomenon tee Which, in the cleaning and sealing treatment, could easily lead to the "flow of color." To enhance color fastness, often with a low concentration of aluminum tee prolong staining time supply price, the dye molecules fully penetrate deep into the pores of the oxide film, which would also help tone and fastness. Tubes are divided into the following categories | Yu Cheng Alcoa aluminum tubes feature is divided into the following categories according to shape divided: the tube, pipe, tube pattern, shaped by extrusion points: seamless tubes and the general squeeze tubes by Accuracy Score: ordinary aluminum tubes and precision tubes, precision tubes which generally require reprocessing after extrusion, such as cold-drawn precision pumping, rolling press thicknesses: Normal and thin-walled tubes aluminum performance: corrosion resistance, light weight.
