美国PARKER CHOMERICS(派克固美丽)是一家世界知名的屏蔽材料供应商,该公司的产品几乎覆盖了所有的相关应用领域。绝大多数的屏蔽应用,都是采用金属或金属化的材料,包括导电布料、导电橡胶,等等。因此,在许多高标准或者特殊的应用环境中,耐电偶腐蚀特性,会是一个十分重要的设计需求,必须在设计过程中得到充分的考虑。

 

图1 电偶腐蚀原理示意图

 

先简单解释一下,什么是电偶腐蚀?电偶腐蚀也称为双金属腐蚀或异种金属腐蚀,主要是由于不同金属间的电位差,以及存在电解质,最后造成金属表面破裂的现象。也就是说,产生电偶腐蚀现象,需要满足三个条件:1.不同金属互相接触,产生电位差。电位差越大,电流失配就越明显,电偶腐蚀就会越严重。例如铂、银、蒙乃尔合金的腐蚀电位较低,铜、铝、锡的腐蚀电位较高。2.不同金属间的电通路。3.能够分解金属的电解质溶液,普通的湿润大气环境或者盐雾环境都会造成湿气凝结于法兰或垫圈接口处,从而形成电解质溶液,当然盐雾环境更加恶劣一些。

了解了什么是电偶腐蚀之后,再来考虑如何设计耐电偶腐蚀的屏蔽垫圈应用。很明显,有两个主要的方向,首先尽量选用电位相近的金属材料,但是由于实际应用中还有很多其他的需求,所以,这一点往往很难直接得到满足。所以,通常会考虑耐电偶腐蚀的第二个方向,尽量少的产生电解质溶液,即提高耐盐雾腐蚀的能力。例如在恶劣环境中使用的铝质基板,我们会建议采用铬酸盐涂层;对于钢或者铜基本,我们会采用镀镍或镀锡的方式,降低表面活性。除此以外,还推荐一款派克固美丽生产的CHO-SHIELD 2000系列导电涂料,可以在基板表面创造一个导电性良好且化学性能稳定的表面,可用于恶劣环境中的高水准EMI屏蔽应用。这款涂料由特殊添加剂和稳定剂配制而成,在高温下仍能保持良好的电气稳定性。总共有2001、2002和2003三款产品,其中2001和2003两款含有可溶性铬酸盐,主要用于铝质基板应用,2003为深色款;2002不含铬酸盐,用于非铝质基板的应用。

 

配置了基板材质以后,接下来就要考虑相应的屏蔽垫圈材料,本文主要讨论的是橡胶屏蔽垫圈的设计。在过去的几十年里,镀银铝填充橡胶已经取代了镀银铜或镀镍石墨等传统材料,在潮湿和盐雾环境中表现出了优秀的耐腐蚀特性。但是,近年来派克固美丽发现镀镍铝填充的橡胶材料,在化学膜铝法兰上表现出了最佳的稳定性,即使与镀银铝相比,活性也降低了20~50%。因此,在此类应用中,镀镍铝填充橡胶具有最佳的EMI屏蔽效能和耐电偶腐蚀特性,而镀银铝填充橡胶则是第二好的替代材料。在派克固美丽的产品库中有三款推荐的镀镍铝导电橡胶材料,分别为CHO-SEAL 6502(硅橡胶)、CHO-SEAL 6503(氟硅橡胶)和CHO-SEAL 6460(EPDM);以及三款镀银铝导电橡胶,分别为CHO-SEAL 1298(氟硅橡胶)、CHO-SEAL 1285(硅橡胶)和CHO-SEAL 1287(氟硅橡胶)。这六款导电橡胶材料在性能上略有差异,具体可登录世强或派克固美丽官网进行查询和选型。

【应用】如何正确规范地喷涂Parker Chomerics导电涂料

大多数Parker Chomerics导电涂料由相对低粘度涂料溶液中的片状或粉末状金属颗粒组成。 因此,在混合和使用时必须特别注意防止金属颗粒沉淀在涂料溶液中。从大容量(> 1升)的容器施加的涂料需要机械搅拌,即涂料容器中的气动混合器。混合涂料•将涂料罐放在涂料搅拌器上3-4分钟,或用大刮刀手工混合,直到所有固体都是均匀的悬浮液,才能很好地混合导电涂料。确保容器的底部或侧面没有未混合的材料。

【选型】Laird 导电橡胶材料选型参考,三种橡胶基质,七种填充材料

从选型角度考虑,导电橡胶材料比较关键的指标有屏蔽效能、体积电阻率、适用温度范围、材料的硬度和强度等,主要由金属填充材料的种类、填充比例、制作工艺和橡胶基质(密度、工艺等)决定。Laird推荐的导电橡胶基质有三种,EPDM(三元乙丙橡胶)、硅橡胶和氟硅橡胶。以填充物材料为区别,将Laird推荐的19款导电橡胶材料分为7个大类,简单介绍一下各自的特点和应用优势,可作为选型参考。
