不锈钢虽被称作不锈钢,但也绝非不会生锈,我们在使用不锈钢紧固件的时候必须要知道如何避免产品生锈。在使用过程中,生锈是常见的现象,也是让我们烦恼的事情,这样不仅会影响到美观程度,同时会影响到不锈钢螺丝的使用性能。
因此我们在使用不锈钢螺丝的过程中一定要注意其中的使用要点。以下是小编总结的四点,供大家参考:
1、在有污染的空气中(如含有大量硫化物、氧化碳、氧化氮的大气),遇冷凝水,形成硫酸、硝酸、醋酸液点,引起化学腐蚀。
2、不锈钢螺丝表面粘附有机物汁液(如瓜菜、面汤、痰等),在有水氧情况下,构成有机酸,长时间则有机酸对金属表面的腐蚀。
3、粉尘或异类金属颗粒的附着物,在潮湿的空气中,附着物与不锈钢螺丝的冷凝水,将二者连成一个微电池,引发了电化学反应,保护膜受到破坏,称之谓电化学腐蚀。
4、不锈钢表面粘附含有酸、碱、盐类物质(如装修墙壁的碱水、石灰水喷溅),引起局部蚀。
