Why Do Some Aluminum-type Materials Be White?

Why do some aluminum -type parts whitening? The sales market of aluminum profiles in this stage is one of the very commonly used aluminum profiles. Aluminum profiles can be processed and processed into different colors of the original color aluminum production through multiple solutions. Requirements to customer applications.
The method of aluminum -type coloring often uses the method of coloring nickel salt electrolysis, but it often occurs problems, such as: the electrolytic method of aluminum materials is not color, dark pattern and white hair, etc. What should we do for this situation? In the course of the preparation processing process, there are several aspects of the solution: the three water cleaning time after alkali erosion is 3-5 seconds, the gas of the gas, the gas of gas The time for the medium immersed pots must be adjusted in 2-5 seconds; the temperature of the alkaline erosion slot must be manipulated in the middle of 45-55 C. After the alkaline erosion slot is opened, it is also indispensable to install a cold water pipe after installing the heating pipe. Create a refrigeration cycle for anode oxidation grooves. Under the prerequisite to ensure that aluminum profiles and conductive rod touch the excellent prerequisite, the slot is manipulated at 50-80 cubic meters; Ion concentration value, when the special device is failed, should be reconstructed on the switch epoxy resin on time.
Treatment of the white hair problem of aluminum profile: In the middle of the conductive beam and the conductive rod, in the middle of the conductive rod and the aluminum profile, be sure to use a steel brush to polish and polish and clean, and then tighten it well. 30mm. After the aluminum profile air is oxidized, the aluminum profile and the conductive rod must be tightened.
Use low current strength or low -voltage to develop aluminum profile air oxidation.
Generally manipulate the current volume of 100-120A/m2, and the working voltage is 14-16V.
Aluminum profiles are not colorful to occur. There is also a solution to the problem of colored problems: when the groove liquid pH is too low, everyone must immediately open the special machine and equipment. In the case, everyone must add thickening agents. After strictly carrying out the cleaning time of the water cleaning of the three water after the oxidation of aluminum -type air, we must ensure that the three water washing water also had pH, and the 3rd water cleaning flow circulation system was increased. The best temperature of the upper color liquid is 22-25 C. In the color tank, you must install the heating tube, and it is difficult to avoid the water condenser, which can make the temperature be reasonably manipulated. In the whole process of alkali erosion, we must maintain the consistency of the front, back, left and right two -mounted aluminum profiles, and have temperature according to the concentration value of the alkaline solution, and the time to match the time to match the time of alkali erosion.
