現(xiàn)在鋁板在我們?nèi)粘Ｉ钪泻艹Ｒ?jiàn)，而且鋁板有很多的類(lèi)型，鋁板在生產(chǎn)過(guò)程中會(huì)出現(xiàn)一些黑斑，那么會(huì)導(dǎo)致鋁板表面上怎么會(huì)出現(xiàn)黑斑?這些黑斑是無(wú)法去掉的，下面鋁板生產(chǎn)廠家給大家講解一下。
Now aluminum plate is very common in our daily life, and there are many types of aluminum plate. There will be some black spots on the surface of aluminum plate in the production process, so how can there be black spots on the surface of aluminum plate? These black spots cannot be removed. The aluminum plate manufacturer will explain them to you.
現(xiàn)在的鋁板有不同種類(lèi)，但是這些鋁板的材料，在加工的時(shí)候，零件如果沒(méi)有出現(xiàn)黑斑的狀況，這不是原材料的缺陷而導(dǎo)致的故障，導(dǎo)致鋁板加工出現(xiàn)黑斑的故障的原因是硫元素對(duì)鍍銀層的影響。
Now there are different types of aluminum plates, but if there are no black spots on the parts during processing, it is not caused by the defects of raw materials. The reason for the black spots in aluminum plate processing is the effect of sulfur on the silver coating.
鋁板在噴漆工藝方面，發(fā)現(xiàn)噴漆加工，出現(xiàn)整批返修的紀(jì)錄，原因就是缺口未堵上，在表面沒(méi)法清除，為防止此類(lèi)故障的發(fā)生，缺口封死，零件未及時(shí)包裝并密封保存，久置在電鍍廠房中而導(dǎo)致鍍銀層變黃。
In terms of the painting process of aluminum plate, it was found that the whole batch of repair records were found in the painting process, because the gap was not blocked and could not be removed on the surface. In order to prevent the occurrence of such failures, the gap was sealed, the parts were not packaged and sealed in time, and the silver plating layer turned yellow after being left in the electroplating workshop for a long time.
故障零件在鍍銀后，及時(shí)包裝并置于干燥器皿中保存，這并不是受到廠房空氣氣氛的影響，在生產(chǎn)條件的情況下，同期加工的類(lèi)似零件沒(méi)有出現(xiàn)故障，所以排除了電鍍生產(chǎn)條件發(fā)生改變的因素。
After silvering, the faulty parts are packed in time and stored in dry containers. This is not affected by the air atmosphere in the workshop. Under the production conditions, similar parts processed at the same time do not have faults, so the factors that affect the electroplating production conditions are eliminated.

加工過(guò)程的表面處理工藝中使用了強(qiáng)腐蝕性的清洗劑，對(duì)鋁的基體造成了腐蝕現(xiàn)象，從而導(dǎo)致鋁材發(fā)黑。
In the surface treatment process of the processing process, a strong corrosive cleaning agent is used, which causes corrosion to the aluminum substrate, resulting in the blackening of the aluminum material.
存放環(huán)境溫度與濕度較高，鋁的性質(zhì)活潑，在這種環(huán)境中鋁會(huì)產(chǎn)生氧化，并形成一層暗色的氧化膜。
The storage environment is high in temperature and humidity, and the nature of aluminum is active. In this environment, aluminum will oxidize and form a dark oxide film.
經(jīng)過(guò)壓鑄、機(jī)械加工后，使用清洗劑未能清洗干凈，表面長(zhǎng)時(shí)間存在殘留物，出現(xiàn)霉斑。
After die casting and machining, the cleaning agent was not used to clean the surface, leaving residue and mildew on the surface for a long time.
處理工藝不合理，在使用清洗劑清洗、拋光等表面處理后，未能及時(shí)進(jìn)行防氧化，或者鈍化處理，導(dǎo)致鋁合金發(fā)生腐蝕、氧化。
The treatment process is unreasonable. After surface treatment such as cleaning and polishing with cleaning agent, the oxidation prevention or passivation treatment is not carried out in time, resulting in corrosion and oxidation of aluminum alloy.
以上就是小編給大家講解的鋁板表面上怎么會(huì)出現(xiàn)黑斑全部?jī)?nèi)容，相信對(duì)大家都有了一定的了解，希望可以幫助大家，鋁板在加工時(shí)會(huì)出現(xiàn)黑斑的故障的原因就是硫元素對(duì)鍍銀層的影響。您有什么疑惑可以隨時(shí)來(lái)咨詢(xún)我們http://m.texjob.com.cn！
The above is the whole content of how black spots appear on the surface of aluminum plate explained by the editor. I believe that we have a certain understanding of it and hope it can help you understand that the reason why black spots appear on the surface of aluminum plate during processing is the effect of sulfur on the silver coating.
