In the whole process of aluminum plate application, it is inevitable to encounter many product quality problems. Some product quality problems are caused by the carelessness of the workers during the whole production process, while some product quality problems are caused by poor actual operation in the mid-to-late application process. Therefore, aluminum plate manufacturers can actually avoid the root causes of aluminum plate product quality problems.
When producing aluminum plates, it can be avoided from the actual operation and application of machinery and equipment. There are many common product quality problems for aluminum plates, and the problem of oil stains is one of the common quality losses. The oil stain does not mean that the aluminum plate is stained after production. It is just that after the cold rolling of the aluminum plate, the aluminum plate manufacturer puts too much oil on the surface of the aluminum tip, and also adds the remaining grease except the rolling oil film. , In the middle and late stages of product inquiries and split production, you will find this kind of oil visible to the human eye on the outside.
A lot of grease is mainly scattered on the top and bottom of the entrance and exit of the extruder or at the neck of the roll. After splashing, it drips on the surface of the box, and then it is found in the extruder roller cleaner because of the oil leakage of the extruder thickness measuring head. Abnormal condition, and the composition of this oil is messy and very dirty. This kind of oil stains on the surface of the aluminum plate produced by the aluminum plate manufacturer causes a lot of harm to the appearance of the alloy aluminum plate. At the same time, when everyone assesses the quality of aluminum plates, the number of oily defects is one of the key criteria. On the one hand, because the thickness of the aluminum plate is relatively thin, it is easy to produce foam during the subsequent quenching, and because there is too much residual oil on the surface, there will be a lot of residue on the surface of the aluminum plate, which will also cause the application performance in the middle and late stages to be not very good. . On the other hand, if the appearance of the aluminum plate is sufficient and clean, it can be used as an aesthetic requirement for interior decoration and packaging products, otherwise it cannot be sold.
Could it be said that there is no way to avoid such product quality problems during production? Naturally, it is not. In fact, aluminum sheet manufacturers can conduct comprehensive and strict inquiries on the production machinery and equipment before they produce aluminum sheets. If there are a lot of oil stains in the machinery and equipment itself,
It should be cleaned up immediately and dealt with properly for reasons. At the same time, we should also clean up the surface of the products produced. If the aluminum plate manufacturer has oil stains that are not clean at the beginning, the product will be reported immediately. If you let the oily products into the warehouse or into the sales market, it is always more difficult to control the product quality afterwards, and there are many after-sales service problems that cannot be solved. The aluminum plate is also very easily scratched. There are actually many reasons that cause the aluminum plate to be scratched, scratched or knocked. It may be caused by the scratches on the surface of the rollers and guide rollers. The scratch of the aluminum plate is generally a groove-like scar that sometimes disappears or persists when it appears on the outside.
