What Is The Dark Spot On The Surface Of Aluminum Sheet?

What is the dark spot on the surface of Aluminum Sheet?
In the Aluminum Sheet factory or application process, sometimes there will be above the situation of dark spots, for this situation is how is it? We have to study the next. The first is the Aluminum Sheet plate material, Aluminum Sheet manufacturers produce Aluminum Sheet plate is made of 0.5mm thick LF21 Aluminum Sheet sheet processing. This type of Aluminum Sheet plate has a variety of the same material, similar to the shape, with the process of parts, while the same period of processing of similar parts of the shape did not appear such failure. And this is not the failure of raw materials caused by the failure. Then it is in the processing technology, on the cover of the silver line of the general process: machine plus pieces - pre-treatment - dip zinc - electroplating zinc - electroplating copper - electroplating silver - paint - dip 823 ─ storage.
In the Aluminum Sheet plating process, first of all, there may be a certain part of the production process has changed, leading to failure. However, the survey found that in the production conditions did not change any situation, the same period of processing of similar parts did not appear such failure. As a result, the factors that change the plating conditions are excluded. According to the previous production experience, the most common cause of silver discs is the effect of sulfur on silver plating.
In the past, there have been silver after the parts did not timely packaging and sealed to save, for a long time in the electroplating plant and lead to silver plating layer yellow. But the faulty parts are silver plated, are packaged in a timely manner and placed in a dry container to save, we can see that this is not affected by the plant air atmosphere. In the painting process, found the cover of the paint processing, there have been repeated records of the repair. The most important reason is that the gap is not blocked, so that paint mist into, and attached to the surface of the silver plating and can not be cleared. In order to prevent the occurrence of such failures, the process of processing, it is recommended to use 3M tape will be sealed to seal, to prevent the paint fog into.
Through this method of exclusion, we found the root of the problem, we immediately take measures to eliminate the recurrence of hidden dangers, making the surface of the Aluminum Sheet as bright as the new factory rate greatly improved.
First of all, Aluminum Sheet production process is not simple. First, want to produce a regular pattern on the Aluminum Sheet plate pattern is not very simple, which means that the process more than a process, not only increased the input of the machine equipment, more cost more human energy, cost Greatly increased; second, the surface of the pattern formed by not only play a decorative landscaping effect, more is to assume a special use of the environment under the anti-skid effect, as the lines more clear, tire anti-skid and grip The stronger the ability.

Secondly, there are many types of Aluminum Sheet can be used for different industries. First, the ordinary Aluminum Sheet alloy sheet, is to ordinary 1060 Aluminum Sheet as a raw material for processing, production and processing costs are relatively low, suitable for general conditions of the cold, the vehicle floor; second, Aluminum Sheet-manganese alloy sheet, Alloy 3003 as the main raw material for processing, with a certain strength and impact resistance, a certain degree of rust and corrosion resistance, mainly used in the train compartment; third, Aluminum Sheet-magnesium alloy sheet, is 5052 or higher Level of Aluminum Sheet processing, with high strength and hardness, rust and corrosion resistance is very strong, can be used for ships and even aerospace industry which.

Finally, Aluminum Sheet is also a metal material, in the daily use of the process also need to use scientific methods for maintenance. First, regular cleaning, for the surface of the stain to use the water or the corresponding cleaning agent in addition to cleaning, stains easily lead to corrosion of the plate deformation; second, the use of professional spray coating on the surface of the film coating, on the one hand Can give Aluminum Sheet to form a barrier, effectively prevent corrosion, on the other hand can play a beautification of the role of decoration, to help it better into the use of the environment.

With the increasing demand for Aluminum Sheet sheets in all walks of life, the plate itself is constantly undergoing technological innovation. Aluminum Sheet is the product of this innovation, and its appearance makes traditional Aluminum Sheet and other plates fade out of the market because It has a lot of excellent features. However, any thing in the course of the use of corrosion and wear will occur, or the need to strengthen the maintenance work to extend the service life.
