1、济南铝板http://www.jngdly.com/化学抛光光亮度没有达到预期的目标,其原因可从特殊铝材的生产工艺和化学抛光工艺这两方面分析。建议采用铝纯度99.70%及其以上级别的铝锭来生产特殊铝材;铝材加工工艺中质量控制为化学抛光得到高光亮度表面奠定基础。
Jinan aluminum chemical polishing brightness does not achieve the desired objectives, the reason can be analyzed from a special aluminum production process and chemical polishing process in these two areas. Recommended and above 99.70% purity aluminum ingots for the production of special grade aluminum; aluminum processing quality control for the chemical polishing process to obtain a high surface brightness foundation.

2、济南铝板化学抛光时间不足,温度不够,搅拌不充分,槽液老化等也会使化学抛光表面光亮度不足。槽液的相对密度较大,防止铝材浮出抛光槽液的液面,致使上部铝材光亮度不足。水的影响造成光亮度不足,往往容易被忽视。最好用干燥的铝材进入化学抛光槽液,杜绝水分的带入。
Jinan aluminum chemical polishing enough time temperature is not enough to sufficiently stir, bath aging, also causes less chemical polishing surface brightness. The relative density of the bath is large, preventing polished aluminum floating bath liquid, resulting in lack of upper aluminum brightness. The effect of water shortage caused by the brightness, often easily overlooked. Best to use dry chemical polishing of aluminum into the bath, to prevent moisture into.

3、济南铝板http://www.jngdly.com/化学抛光后的铝材表面上附着有一层白色的沉积物,且分布不均匀,附着物底部的铝材表面有可能被腐蚀。通常,该缺陷是因为化学抛光槽液中溶铝量太高所致,需采取措施调整槽液中的溶铝量到正常的范围内。
Jinan aluminum chemically adhered on the aluminum surface after polishing layer of white sediment, and uneven distribution, the bottom of the aluminum surface attachments may be corroded.Typically, this defect is due to a chemical polishing bath soluble aluminum content is too high due to the need to take measures to adjust the amount of aluminum melting bath to within normal range.
