每天我们欣赏美和穿抗拒ance of decorative coatings in our kitchens and bathrooms. Chromium plate, whether with high lustre, bright or luxurious satin finishes provide an easy to clean, low maintenance surface that will continue to provide corrosion resistance in high humidity areas for many years.
For MacDermid Enthone the key starts with correct preparation. Substrates which are commonly used in sanitary applications include plastic (ABS), brass and Zinc Based Die Castings (ZBDC or Zamak). Metal surfaces are cleaned and activated in Metex pre-treatment systems. For the plastic substrates MacuPlex provides the metallization and excellent adhesion required prior to copper and nickel electroplating.
Chromium provides the corrosion protection and final finish
Nothing captures today’s style and fashion like chromium. Elegant, timeless and enduring, chromium is an iconic finish.
今天，Mac188金宝搏官网版下载Dermid提供了一个令人兴奋的新系列较深的装饰铬涂料。这些涂料包括烟熏，半黑和全黑。他们还符合当今苛刻的腐蚀性能标准，包括服务条件2. ISO 1456和ASTM B456将服务条件2称为“可能发生冷凝的室内”。我们所有的铬涂料都超过了这一要求*。当您需要风格和性能时，思考和想象...更多来自MacDermid。188金宝搏官网版下载
* with the appropriate pre-treatment and copper / nickel layers as laid out in these specifications.
In duplex coatings the base layer is a sulfur-free 'semi-bright' deposit with excellent corrosion resistance. The bright or satin layer is then applied over this sulfur-free deposit. These coatings will meet or exceed Service Condition 2 requirements.
In multilayer deposits, the third layer is a microporous nickel coating over the bright or satin layer. This coating will meet and exceed Service Condition 3 requirements.
镀铬黄铜是龙头的首选基板。Zamak用于制造通常在浴室和厨房内找到的其他组件，例如坐抚养者和铰链。黄铜或Zamak通常是抛光或振动完成，以产生光滑且亮的表面。任何抛光残留物必须在MacDermid Buff OFF或METEX SU 486188金宝搏官网版下载浸泡或超声波清洁器中除去。然后在诸如Metex T103的温和碱性清洁剂中脱脂，在诸如Metex T103的温和碱性清洁剂中脱脂，以在电加密之前除去任何残留的油和污垢。
Brass is usually treated cathodically
Zamak is usually treated anodically
Plastics such as ABS are used for fittings such as shower facia and controls. This material requires the specialized MacuPlex Plating On Plastic pre-treatment system. New engineering plastics such as PEEK, Nylon and Ultem can also be metalized using the Surface Activation process. As these plastics are generally more durable than ABS, they offer the design engineer possibilities to replace metal substrates with plastic. In combination with the Surface Activation process, the finished component retains the important metallic 'feel'.
Copper is extensively used as the first layer in chrome plumbing coatings. It is a ductile and exceptionally bright / well levelled deposit. Copper can be electrodeposited from an acidic or alkaline solution, depending on the substrate and desired properties.
