铝板的表面如果出现凹坑黑点，密密麻麻的将会严重影响表面质量，那么铝板表面黑点是什么?是怎么引起的？如何避免表面黑点问题呢？下面铝板生产厂家为您讲解。
If there are pits and black spots on the surface of aluminum plate, the surface quality will be seriously affected. What are the black spots on the surface of aluminum plate? How did it happen? How to avoid the problem of black spots on the surface? Next, the aluminum plate manufacturer will explain to you.
对于许多外观件产品，对于表面要求都比较严格，如果表面出现黑点将会影响产品质量，但是很多人都不知道黑点是怎么导致的，其实铝板表面黑点是静电导致的，铝板经过颠簸摩擦以后会出现摩擦生电的物理现象，而当静电释放以后将对铝板的表面破坏导致出现直径很小，凹陷很浅的凹坑麻点。
For many appearance products, the surface requirements are quite strict. If there are black spots on the surface, the product quality will be affected. However, many people do not know how the black spots are caused. In fact, the black spots on the aluminum plate surface are caused by static electricity. After the aluminum plate is subjected to bumpy friction, the physical phenomenon of friction and electricity generation will occur. When the static electricity is released, the surface of the aluminum plate will be damaged, resulting in small diameter and shallow pits.
那么我们如果避免铝板表面黑点问题，就要先避免铝板的剧烈颠簸，不摩擦就不会放电，所以铝板包装一定要牢固，其次可以将铝板隔离，比如隔纸或者贴膜，铝板和铝板之间有了保护层那么就不会出现静电问题。
If we want to avoid the problem of black spots on the aluminum plate surface, we must first avoid the sharp bumps of the aluminum plate, and no electric discharge will occur without friction. Therefore, the aluminum plate packaging must be firm, and then we can isolate the aluminum plate, such as paper separation or film pasting. If there is a protective layer between the aluminum plate and the aluminum plate, then there will be no static electricity problem.

铝板表面黑点没有好的办法修复，如果是后续需要喷涂喷漆则不需要管它，而如果不做任何处理的话就不太好解决这种问题了，所以我们要做好保护工作，避免静电的产生，才能保证铝板表面不会出现黑点。
There is no good way to repair the black spots on the aluminum plate surface. If it is necessary to spray paint later, it is not necessary to deal with it, and it is not easy to solve this problem if no treatment is done. Therefore, we should do a good job of protection to avoid the generation of static electricity, so as to ensure that the aluminum plate surface will not have black spots.
此外有些铝材表面有黑斑、发暗现象，可能是铝合金成分中的铁元素超标，也可能是熔炼的原材料质量差。尤其是价格远低于市场行情价的铝材，力学性能、防腐蚀性能十分差劲。铝材长期存放于湿热环境中，时间一长，也会出现腐蚀、发黑现象。
In addition, there are black spots and darkening on the surface of some aluminum materials, which may be caused by the excessive iron element in the aluminum alloy composition, or the poor quality of raw materials for smelting. In particular, the mechanical properties and anti-corrosion properties of aluminum, whose price is far lower than the market price, are very poor. Aluminum materials will be corroded and blackened after being stored in a hot and humid environment for a long time.
