钢板网表面处理防锈方法
Rust prevention method of steel mesh surface treatment
一、在普通钢铁中加入一些稀有元素等成分改变金属的内部组织结构。
1、 The addition of some rare elements in ordinary steel can change the internal structure of the metal.
二、在金属表面覆盖保护层，隔离周围腐蚀介质，从而防止达到防腐蚀效果。例如：在钢板网表面涂上机油、凡士林、油漆或覆盖搪瓷、pvc等耐泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备  托辊生产线腐蚀的非金属材料；用电镀、热镀、喷镀等方法，在钢板表面镀上一层锌、铬、镍等；用化学方法使钢铁表面生成一层细密稳定的氧化膜。如在机器零件、枪炮等钢板制件表面形成一层细密的黑色四氧化三铁薄膜等。
2、 The metal surface is covered with a protective layer to isolate the surrounding corrosive medium, so as to prevent the anti-corrosion effect. For example: oil, Vaseline, paint or enamel, PVC and other corrosion-resistant non-metallic materials are coated on the surface of steel plate mesh; zinc, chromium, nickel are plated on the surface of steel plate by electroplating, hot plating, spray plating and other methods; a fine and stable oxide film is formed on the surface of steel plate by chemical methods. For example, a thin layer of black Fe3O4 film is formed on the surface of steel plate parts such as machine parts and guns.
三、经常擦拭金属器材或者在精密仪器中放置干燥剂和在腐蚀介质中加入少量能减慢腐蚀速度的缓蚀剂等。
3、 Often wipe metal equipment or place desiccant in precision instrument and add a small amount of corrosion inhibitor which can slow down the corrosion rate.
