我们为何要关注滑轨的表面处理?
作者:{author} 发布于:2017-08-28 11:13:20

Choosing the right metal finish isn’t just a matter of color. It’s a complex andintricate process that affects the functionality and even lifespan of the metal.

选择正确的金属表面处理不仅仅是颜色的问题。它是一个错综复杂的工艺过程,会影响金属的功能和寿命。

 

Think about the Golden Gate Bridge,completed in 1937, the bridge’s finish has stood up to the salt-laden fog of the San Francisco Bay for 80 years. While the “International Orange” paint has become the bridge’s trademark, it’s not there for aesthetics. The finish is there to protect the bridge from corroding as a result of the salt in the air from the Bay. The original lead paint was replaced with an inorganic zinc silicate primer and vinyl topcoat to protect against advanced corrosion.

想想1937年完工的金门大桥吧,桥梁的表面处理已经在旧金山海湾的盐雾中挺立了80年。虽然“国际橙”这个标准油漆方案已经成为桥梁的响亮招牌,但在这里并非出于美学考虑。这里的表面处理主要是为了保护桥梁免受来自海湾空气中的盐份腐蚀。原来的铅漆被无机硅酸锌底漆和乙烯基面漆替代,以防止高强度腐蚀。

In producing sliding hardware that sees a variety of different applications and environments, we need to protect our slides from the elements just like that of the Golden Gate Bridge. That’s why we have incorporated slide finishes to accommodate the needs of every environment our slides will see.

滑轨硬件有多种不同的应用方法和应用环境,在生产滑轨硬件的过程中,我们需要像金门大桥那样保护我们滑轨免受各种因素的影响。这就是我们整合滑轨表面处理方案,以适应其不同应用环境的原因。

A finish is a protective, chemical layer that helps a metallic surface resist corrosion. Aside from the stainless variety, steel is vulnerable to even light moisture. Thus, proper finishes can extend a drawer slide’s life by years.

表面处理是一种保护性化学层,有助于金属表面抵抗腐蚀。除了不锈钢外,钢材都容易受潮湿环境的影响。因此,适当的表面处理可以将抽屉滑轨的使用寿命延长数年。

Just what goes into a slide finish? Let’s find out.

滑轨表面处理究竟加入了什么成份?让我们来看看吧。

Accuride offers four types of coated finishes for its carbon steel slide members:

雅固拉为碳钢滑轨构件提供了四种涂层的表面处理方案:

  1. Zinc

  2. Black

  3. Electroplate

  4. White Electrocoat Weather-Resistant

 

  1.镀锌

  2.黑色镀锌

  3.电镀

  4.白色电泳

\

Zinc is the most common of the three finishes: It uses a zinc base layer coated by clear or black chromate. The clear zinc coat, the standard finish, resists a moderate degree of corrosion. It’s best for indoor environments, like office and home cabinetry.

锌是最常见的三种表面处理剂之一:它使用由透明或黑色铬酸盐涂层的锌基层。锌涂层,即标准涂层,能抵抗中等程度的腐蚀。它最适合室内环境,如办公室和家庭橱柜。

Black electroplate, often used, by comparison, offers eight times more corrosion-resistance as clear zinc and tends to be used on dark-colored cabinetry. White electrocoat offers, even more, corrosion resistance on kitchen fixtures and appliances—applications that are often white, to begin with. These colors help the slides blend intothe applications they’re used on. Our weather-resistant slides use a standard zinc finish with extra coating to protect the slide from the elements in outdoor applications.

相比之下,经常使用的黑色电镀层,能提供8倍于镀锌层的抗腐蚀性,并且倾向于在深色橱柜上使用。白色电泳拥有更强的耐腐蚀性,可用于厨房家具和电器– 首先通常是白色的外观。这些颜色有助于滑轨与其应用环境融为一体。我们的抗风化滑轨在标准镀锌的基础上增加额外的涂层,可以保护滑轨免受户外环境因素的影响。

You may be wondering where the “electro” come in. The electro part is from the role that positive and negative attraction plays when bonding the desired finish to the slide member. That powerful attraction gives the finish and slide surface a strong bond that leading to a tidy and resilient finish.

您可能想知道“电镀”的原理。电镀部件是在滑轨构件上进行所需的表面处理时由于阳极和阴极的吸引作用而产生的。这种强大的吸引力在表面处理和滑轨表面形成了一种强大的粘结作用,从而形成了一种整洁而又抗风化的表面。

Additionally, there are corrosion-resistant aluminum and stainless steel slides, such as our ‘AL‘and ‘SS‘ drawer slide families. These types of slides offer the most resistance to corrosion. The ‘AL‘slide family consists of a slide with Aluminum race ways such as our, super heavy-duty AL4120 that boasts a load rating of up to 1,212 lbs.

此外,还有耐腐蚀的铝制滑轨和不锈钢滑轨,如我们的“AL”和“SS”滑轨系列。这些类型的滑轨具有最强的耐腐蚀性。“AL”滑轨系列包括铝质滑轨轨道,如我们的超重型AL4120,额定载荷可高达1,212磅。

From our stainless steel selection, slide SS0330 is ideal for applications subject to moisture or humidity such as refrigerators and freezers. In general, stainless steel includes anywhere from 10% to 30% chromium for anti corrosion. Accuride stainless steel slides are either austenitic or ferritic.

在我们的不锈钢选材中,滑轨SS0330非常适用于潮湿或湿润的应用环境,如冰箱和冷柜。通常,不锈钢包含10%至30%的铬用于防腐。雅固拉公司的不锈钢滑轨采用的是奥氏体或铁素体钢材。

Austenitic steel is non-magnetic, highly formable, and has high corrosion resistance. Highly formable, austenitic steel is tough, optimalfor welding, and used for such applications as auto trim and industrial hardware.

奥氏体钢村是非磁性,高度可成型的钢材,具有高耐腐蚀性。高度可成型的奥氏体钢很坚韧,最适合焊接,并用于汽车内饰和工业五金等方面。

Ferritic steel is composed of up to 27% chromium (and 0% nickel),and it’s considerably less corrosion-resistant than austenitic steel.

铁素体钢由高达27%的铬(和0%镍)组成,并且在耐腐蚀性上比奥氏体钢要差得多。

Each finish is tested in a salt spray (also known as a salt fog)chamber. As the name suggests, these chambers have slides exposed to salt spray. The more corrosion resistant a slide’s coating, the longer its exposure in the chamber.

每次表面处理都在盐雾实验室进行过测试。顾名思义,这些实验室里的滑轨是暴露在盐雾中的。滑轨涂层的耐腐蚀程度越高,其在实验室内的曝露时间越长。

A basic clear zinc-plated slide is exposed for 12 hours in the chamber with no sign of corrosion. By comparison, an electro-white slide is exposed for 500 hours with no sign of corrosion. Accuride tests its slides under the American Society for Testing and Materials’ (ASTM’s) standards.

基本的镀锌滑轨在室内接触盐雾12小时也没有腐蚀迹象。而与之相比,白色电镀滑轨接触盐雾500小时,也没有腐蚀迹象。雅固拉是按照美国测试和材料协会(ASTM)的标准对其滑轨进行测试。

Similar to the team that maintains the Golden Gate Bridge, we are constantly looking for new and improved ways to ensure our slides are the most resilient in the world.

与维护金门大桥的团队一样,雅固拉在不断寻找新的改进方法,以确保我们的滑轨在世界上具有最强的抗蚀性能。
