铝板氧化处理工艺你了解吗?

来源:

  铝合金的阳极氧化越来越多,可以应用于日常生活中。由于该工艺的特点,铝件表面有一层坚硬的保护层,可用于生产厨房用具等日用品。但铸铝的阳极氧化效果不佳,表面不光亮,只能是黑色。铝合金型材稍微好一点,下面简单先容一下铝板氧化处理的方法。
  More and more anodic oxidation of aluminium alloys can be used in daily life. Due to the characteristics of this process, the surface of aluminium parts has a hard protective layer, which can be used to produce kitchen appliances and other daily necessities. However, the anodic oxidation effect of cast aluminium is not good, the surface is not bright and can only be black. Aluminum alloy profiles are slightly better. Here's a brief introduction to the oxidation treatment of aluminium plate.

  近十年来,铝氧化着色技术在我国得到了迅速发展。许多工厂采用了新技术,在实际生产中积累了丰富的经验。铝及其合金的阳极氧化工艺有许多成熟的、正在发展的方法。
  In recent ten years, aluminium oxide coloring technology has developed rapidly in China. Many factories have adopted new technologies and accumulated rich experience in actual production. There are many mature and developing methods for anodizing aluminium and its alloys.

  在选择氧化工艺前,先了解铝或铝合金材料。因为,材料的质量、组成的不同,将直接影响到铝产品阳极氧化后的质量。洪菊德、范吉对此有专门的评论(见电镀与精加工,no。2、1982年,P.27)。
  Before choosing the oxidation process, we should know about the aluminium or aluminium alloy materials. Because the quality and composition of materials will directly affect the quality of aluminium products after anodizing. Hong Jude and Fanji have special comments on this (see Electroplating and Finishing, No). 2. 1982, P.27).

  例如,铝表面的缺陷如气泡、划痕、剥落、粗糙等,经过阳极氧化后仍然会出现所有的缺陷。合金成分对阳极氧化后的表面形貌有直接影响。
  For example, defects on the surface of aluminium, such as bubbles, scratches, spalling, roughness, etc., will still appear after anodizing. The composition of the alloy has a direct influence on the surface morphology after anodizing.
  例如,含1-2%锰的铝合金氧化后呈现棕蓝色。随着铝中锰含量的增加,氧化后的表面颜色由棕蓝变为深褐色。
  For example, aluminium alloys containing 1-2% manganese show brown-blue color after oxidation. With the increase of manganese content in aluminium, the surface color changed from brown blue to dark brown after oxidation.
  含硅0.6 ~ 1.5%的铝合金氧化后呈灰色,含硅3 ~ 6%的铝合金呈白色。
  Aluminum alloys containing 0.6-1.5% silicon are grey after oxidation, and aluminum alloys containing 3-6% silicon are white.
  锌的呈乳白色,铬的呈金色到灰色,镍的呈淡黄色。
  Zinc is milky white, chromium is golden to gray, and nickel is pale yellow.
  一般来说,只有铝含镁和钛超过5%才含有金,可以氧化得到无色、透明、明亮、干净的外观。
  Generally speaking, only aluminium containing more than 5% magnesium and titanium contains gold, which can be oxidized to a colorless, transparent, bright and clean appearance.
  在铝及铝合金材料的选择中,有必要考虑选择合适的阳极氧化工艺。目前,我国广泛采用的硫酸氧化法、草酸氧化法和铬酸氧化法已在手册、书籍和期刊上详细先容。
  In the selection of aluminium and aluminium alloy materials, it is necessary to consider the appropriate anodizing process. At present, sulfuric acid oxidation method, oxalic acid oxidation method and chromic acid oxidation method widely used in China have been introduced in manuals, books and periodicals in detail.
