前言 铝及铝合金防护装饰,广泛采用硫酸阳极氧化。这样电解液能使铝制品获得防护性能高的氧化膜,并且氧化膜具有较多的孔隙,较强的吸附能力。但此工艺的温度范围窄,电解液必须控制在13～26℃范围内进行,才能保证氧化膜的质量。在氧化过程中,槽温很容易超出它的上限,导致氧化膜起粉。特别是夏季即使是单班制的生产为了维持槽温在工艺规范之内,也必须采用降温措施,这样就带来了投资和能耗等问题。
Preface Aluminum and aluminum alloy decorative decoration, widely used sulfuric acid anodizing. This electrolyte can make aluminum products have high protective oxide film, and the oxide film has more pores, strong adsorption capacity. However, the process of narrow temperature range, the electrolyte must be controlled at 13 ~ 26 ℃ range, in order to ensure the quality of the oxide film. During oxidation, the bath temperature easily exceeds its upper limit, causing the oxide film to powder. Especially in the summer even if the production of a single shift in order to maintain the tank temperature within the process specifications must also be used cooling measures, thus bringing investment and energy consumption and other issues.
