盐雾环境对产品的影响

盐雾环境对产品的影响

盐是世界上蕞普遍的化合物之一。在海洋、大气、陆地表面、以及湖泊和河流中均发现有盐。因此,要避免暴露在盐雾中是不可能的。通常,在沿海地区的影响蕞严酷。装备暴露于腐蚀大气环境的影响主要分为三类:腐蚀影响、电气影响和物理影响。考虑下列典型问题有助于确定本方法是否适用受试装备。下列问题不包括全部影响。
1  腐蚀影响
a   电化学反应引起的腐蚀。
b  加速应力腐蚀。
c   盐在水中电离后形成的酸/碱溶液。
2  电气影响
a   由于盐沉积引起电子装备的损坏。
b  导电层的产生。
c   绝缘材料和金属的腐蚀。
3  物理影响
a   机械部件和组件的活动部分的阻塞或粘连。
b  由电解作用导致漆层起泡。
Salt spray environment,theimpact of the product

Salt is the world's one of the most common compounds. In theoceans,atmosphere, land surface, as well as lakes and rivers arefound insalt. Therefore, to avoid exposure to salt spray ispossible.Typically, the most severe impact in the coastal areas.Equipmentexposed to corrosive effects of the atmosphericenvironment can bedivided into three categories: corrosioneffects, electrical effectsand physical effects. Consider thefollowing typical questions helpdetermine whether this method isapplicable to subjects andequipment. The following issues do notinclude the full impact.
1. Corrosion
a, electrochemical reaction caused by corrosion.
b, accelerated stress corrosion.
c, salt ionization in water formed after the acid /alkalinesolution.
2. Electric effect
a, because of salt deposition caused by damage toelectronicequipment.
b, conductive layer generation.
c, insulating materials and metal corrosion.
3. Physical effects
a, mechanical parts and components activities, part oftheobstruction or adhesion.
b, lead paint blistering from the electrolysis.
