In the whole production process of alloy aluminum plate, many product quality problems are inevitable. 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. Therefore, aluminum plate manufacturers can actually avoid the root cause of aluminum plate product quality problems.
In the production of aluminum plate, the actual operation and the use of mechanical equipment can be avoided. There are many common product quality problems in aluminum plate, and oil stain is one of the common quality losses. Oil stains do not mean that the aluminum plate will be contaminated after production. But after the cold rolling of aluminum plate, the aluminum plate manufacturer put too much oil on the surface of the aluminum head, and in addition to the rolling oil film, it also added the remaining grease. In the middle and later stage of product consultation and mass production, you will find that the fat is visible to the naked eye.
Many oils are mainly distributed at the top and bottom of the extruder inlet and outlet or at the neck of the roller. After splashing, it will drop on the surface of the box, and then due to the oil leakage of the thickness gauge of the extruder, it is found to be abnormal in the roller cleaner of the extruder, and the composition of the oil is very miscellaneous and dirty. This kind of oil stain on the surface of aluminum plate produced by aluminum plate manufacturer will seriously damage the appearance of alloy aluminum plate.
At the same time, when everyone evaluates the quality of aluminum plate, the number of oil defects is one of the key criteria. On the one hand, as the thickness of the aluminum plate is relatively thin, it is easy to produce foam during the subsequent quenching process, and because there is too much oil on the surface, a large amount of residue will be produced on the surface of aluminum. Aluminum plate, which will also lead to the late application performance is not very good. On the other hand, if the appearance of aluminum plate is clean enough, it can be used as the aesthetic requirements of interior decoration and packaging products, otherwise it can not be sold.
It should be cleaned up immediately and properly disposed of for some reason. At the same time, we should clean the surface of the products. If the aluminum plate manufacturer has unclean oil stains at the beginning, the product will be reimbursed immediately. If the oil 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 is 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 rollers and guide rollers. Scratches on aluminum plates are usually grooved scars that sometimes disappear or persist when they appear on the outside.
