使用的濟南鋁板鋁材質(zhì)量不是很好,里邊夾雜雜質(zhì)太多也會起皮,鋁件進行拋丸處理后,在鋁件上面的氧化層會被破壞了.無法處理的很干凈,一部分氧化層還留在上面。對以上的問題目前沒有行之有效的方法,可以了解基本的處理途徑。
The use of Jinan aluminum aluminum quality is not very good, inside mixed impurities too much will play a skin, aluminum parts for shot blasting treatment, the oxide layer on the surface of the aluminum parts will be destroyed the. Unable to deal with the very clean, a partial oxidation layer still stays in the top. There is no effective way to deal with the above problems, we can understand the basic treatment.

1.進一步提高工件質(zhì)量。To further improve the quality of the workpiece.

2.降低拋丸壓力。Reducing blasting pressure.

3.對拋丸起皮部位進行打磨,如打磨后其底部問題,可重拋。The shot peeling parts such as grinding, polishing the bottom, to be thrown.

濟南鋁板 http://m.pdadn.com/廠家認為，拋丸是為了使工在件得到進一步的壓實,通常每平方厘米受力為3千克力左右,如工件本身存在壓鑄質(zhì)量問題,如氣孔、氣泡、冷隔等,在拋丸打?qū)崟r就會產(chǎn)生起皮現(xiàn)象,這與壓鑄起皮非同一概念,要區(qū)分開來。
Jinan aluminum manufacturers believe that the shot is to enable industry and trade in a further compaction, usually per square centimeter stress is about 3 kg of force, such as workpiece itself die casting quality problems, such as porosity, bubble, cold partition. In the shot blasting play real-time will produce skin phenomenon, which skin and die casting non same concept to distinguish.
