为什么我的报价是铜或锡/铅等功能或哑光饰面的装辞?

高级电镀技术提供的许多饰面具有高度与其相关的化妆品。manbetx公牛明亮的金和光泽镍面漆,如明亮的电解镍或中磷化学镍,是由于内在沉积特征和沉积物中的特定元素而具有更高的沉积光泽和更美容的外观的良好实例。

通过先进电镀技术提供的其他饰面是功能性的,预定毛皮特manbetx公牛定的工程目的。这些饰面的实例包括硅磨锡,锡/铅,铅或氨基磺酸镍面漆,也是铜沉积物。这些饰面适用于特定的工程目的,包括焊接,钎焊,巴比特,电流承载能力或热处理停止。由于这些沉积物的性质,它们可以易于某些化妆品缺点,如果适用,通常会在报价上注明。

Some examples of cosmetic disclaimers include:

哑光矿床,如哑光锡,锡/铅或未致密的镍,如氨基磺酸镍:

这些沉积物是完全遮罩的,并且由于它们被镀覆任何有机添加剂来控制沉积物的外观或晶粒尺寸,因此可以具有略微斑点的外观。这些沉积物也可以非常易于水染色,并且在某些情况下,由于沉积物的结构,手指印刷。对于他们的预期目的来说,这些饰面功能的原因是为什么他们可能具有上面列出的化妆品缺点。如果对浴缸或过程进行改变以改善化妆品,则存款不会按计划执行。

Reactive Deposits such as Copper or Silver:元素铜和银等反应elements in the atmosphere including sulfur bearing compounds and oxygen. The reaction of the deposits with these elements is a thermodynamic fact that can not be altered. These reactions can cause issues such as surface staining or discoloration and tarnishing. The environment in which the parts stored can have a large impact on the reactions and timeframe in which the reactions can occur. There are steps that can be taken including tarnish inhibitors and sealed nitrogen packaging which can compensate for the reactivity of the deposit. If the appearance of reactive deposits is a concern, a representative of the technical sales group at APT can advise of inhibits or packaging methods that can help mitigate these effects.
