鋁板的表面如果出現凹坑黑點，密密麻麻的將會嚴重影響表面質量，那么鋁板表面黑點是什么?是怎么引起的？如何避免表面黑點問題呢？下面鋁板生產廠家為您講解。
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.
對于許多外觀件產品，對于表面要求都比較嚴格，如果表面出現黑點將會影響產品質量，但是很多人都不知道黑點是怎么導致的，其實鋁板表面黑點是靜電導致的，鋁板經過顛簸摩擦以后會出現摩擦生電的物理現象，而當靜電釋放以后將對鋁板的表面破壞導致出現直徑很小，凹陷很淺的凹坑麻點。
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.
那么我們如果避免鋁板表面黑點問題，就要先避免鋁板的劇烈顛簸，不摩擦就不會放電，所以鋁板包裝一定要牢固，其次可以將鋁板隔離，比如隔紙或者貼膜，鋁板和鋁板之間有了保護層那么就不會出現靜電問題。
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.

鋁板表面黑點沒有好的辦法修復，如果是后續需要噴涂噴漆則不需要管它，而如果不做任何處理的話就不太好解決這種問題了，所以我們要做好保護工作，避免靜電的產生，才能保證鋁板表面不會出現黑點。
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.
此外有些鋁材表面有黑斑、發暗現象，可能是鋁合金成分中的鐵元素超標，也可能是熔煉的原材料質量差。尤其是價格遠低于市場行情價的鋁材，力學性能、防腐蝕性能十分差勁。鋁材長期存放于濕熱環境中，時間一長，也會出現腐蝕、發黑現象。
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.
