In the whole production process of aluminum alloy plate, many product problems will inevitably be encountered. Some product quality problems are caused by the carelessness of the staff in the whole production process, while some product quality problems are caused by improper operation in the middle and later stages of application. How to deal with the white spots and oil stains on the alloy aluminum plate?
White spot on alloy aluminum plate
For the aluminum plate with strict appearance requirements, how to prevent white spots on the outer surface of the aluminum plate and make the product smooth and bright is not only related to the processing technology, but also closely related to the subsequent appearance processing technology.
When large aluminum alloy products are anodized, white spots will appear on the surface after processing, especially on the aluminum oxide plate. Let's analyze the factors in this case. In fact, the main factor is very simple: after the aluminum plate is oxidized, the erosion is not complete, resulting in white spots on the surface after boring. The solution is to strengthen the scouring after oxidation and try to rinse it completely with a water gun. At the same time, in the future, you should pay attention to maintaining the appearance and try to keep this product away from other products and dry naturally.
In other words, if we want to better control the appearance of white spots on the aluminum plate, we should not only pay attention to the appearance of the product during the product processing, but also pay attention to prevention during the appearance processing, and standardize the strict processing technology and processing technology to prevent the formation of white spots. Clean white spots, pickling and alkaline washing are OK, but you need to control the concentration, or spray paint to prevent aluminum and oxygen from being touched.
Oil stain on alloy aluminum plate
In the production of aluminum plate, the actual operation and the use of mechanical equipment can be avoided. Aluminum plate has many common product quality problems, and oil stain is one of the common quality losses. Oil stains do not mean that the aluminum plate will be contaminated after production. Only after the cold rolling of the aluminum sheet, the aluminum sheet manufacturer put too much oil on the surface of the aluminum head, and added the remaining grease in addition to the rolled oil film. In the middle and late stages of product consultation and mass production, you will find that this fat is visible to the naked eye.
A lot of grease is mainly distributed at the top and bottom of the extruder inlet and outlet or at the neck of the roll. After splashing, it will drop on the surface of the box, and then it is found to be an abnormal condition in the extruder drum cleaner due to the oil leakage of the extruder thickness gauge, and the composition of this oil is very miscellaneous and dirty. Such oil stains on the surface of aluminum plates produced by aluminum plate manufacturers will seriously damage the appearance of alloy aluminum plates.
Is there no way to avoid this product quality problem at the time of production? Of course not. In fact, aluminum plate manufacturers can carry out comprehensive and strict inquiry on production machinery and equipment before producing aluminum plates. If there are many oil stains in the mechanical equipment,
It should be cleaned immediately and properly disposed of for some reason. At the same time, we should also clean the surface of the products we produce. If the aluminum plate manufacturer has dirty oil stains at the beginning, the product will be reimbursed immediately. If oily products are put into the warehouse or sales market, it is always difficult to control the product quality afterwards, and there are many unsolvable after-sales service problems.
Aluminum plates are also easy to scratch. In fact, there are many reasons for aluminum scraping, scraping or knocking. This may be caused by scratches on the surface of the rollers and guide rollers. Scratches on aluminum plates are usually grooved scars that sometimes disappear or persist when they appear on the outside.
