Industrial aluminum profiles of the three acidification casting slot, although we can adjust the brightness according to a certain ratio, but not only to maintain the brightness, to prevent the generation of pitting, but also to continue the aluminum profile is not easy to be controlled. Then we should pay attention to the adjustment and control of industrial aluminum profiles manufacturers from the following aspects:
1. With automatic line and semi-automatic line polishing material, first of all, the operators should have a certain period of manual polishing experience. In order to add a small amount in time. Both automatic and semi-automatic lines must be adjusted to a polishing time greater than 30 seconds so that defects are not likely to occur. Otherwise, it is difficult for industrial aluminum profiles manufacturers to produce qualified products.
2. With the development of aluminum profile manufacturers, in addition to the concentration and temperature are easy to change, it is also easy to change by the operation mode, suspension mode and the number of clamping. At this time, we need to make judgments and adjustments at any time according to the conditions of the site.
3. In particular, the spacing between aluminum alloy materials is 1 times wider than the conventional anodizing spacing.
4. If you can adjust to the qualified brightness, but there are pockmarks, you should consider the method and way of operation: A. Reduce the temperature; B. evaporation of more water; C. Shorten polishing time; D. Increase air agitation; E. Add 3% nitric acid to the washing tank; F. Use 40 ℃ hot water for washing.
5. After adjusting the tank liquid, we should first adjust the conditions of the operation, and the casting time is greater than 30 seconds, otherwise it is difficult to operate and control the site.
6. With the appropriate concentration, there must also be a correct qualified and skilled operation method, in order to maintain the continuous industrial aluminum profiles manufacturers to produce qualified products.
