铜门发生生锈氧化是什么原因?

1、水泥砂浆
1. Cement mortar
铜门在电焊固定之后,一般需要往门框内灌水泥砂浆加固。由于水泥中含有腐蚀性物质-硅酸盐类,大多数业主为了图省事,铜门固定后都会要求安装师傅帮忙灌水泥砂浆加固。考虑到安装师傅并非水泥工,灌水泥砂浆操作不当,会出现砂浆灌的太满,后期出现砂浆渗漏液与铜门表面接触腐蚀油漆层,导致铜门出现氧化生锈现象。因此,一般铜门加固后,灌水泥砂浆这类工作应该交给泥水工去完成比较妥当。
After the copper door is fixed by electric welding, it is generally necessary to pour cement mortar into the door frame for reinforcement. Due to the presence of corrosive substances such as silicates in cement, most homeowners, in order to save time, ask the installation technician to help reinforce the copper door with cement mortar after fixing it. Considering that the installation master is not a professional cement worker, improper operation of pouring cement mortar can lead to overfilling of the mortar, resulting in mortar leakage and corrosion of the paint layer on the surface of the copper door, leading to oxidation and rusting of the copper door. Therefore, it is generally appropriate to entrust the work of pouring cement mortar after the reinforcement of copper doors to professional mud and water workers.
2、大理石胶
2. Marble glue
定购铜门时,部分业主考虑到铜门或者整体装修风格的原因,选择用大理石作为门套。在贴大理石门套线时,经常会用到大理石密封胶进行封边收口。由于大理石密封胶含有酸性腐蚀液,工人操作不当或者粗心大意,将大理石胶接触到铜门表面,没有及时清理干净,这种情况很容易导致铜门出现氧化生锈现象。
When ordering copper doors, some owners consider the price of the doors or the overall decoration style, and choose to use marble as the door cover. When pasting marble door cover lines, marble sealant is often used for edge sealing and closing. Due to the presence of acidic corrosive liquid in marble sealant, improper or careless workers may come into contact with the surface of the copper door without timely cleaning, which can easily lead to oxidation and rusting of the copper door.

3、空气潮湿
3. Air humidity
铜是一种不太活泼且耐腐蚀的贵金属,但是铜在潮湿环境下,易出现氧化生锈现象。特别是在我国南方会出现“回南天”气候现象,因此在这些地区的铜门门框、门套底部,长时间会出现氧化生锈现象。
Copper is a less active and corrosion-resistant precious metal, but it is prone to oxidation and rusting in humid environments. Especially in southern China, there will be a phenomenon of "returning to the southern sky" climate, so oxidation and rust will occur at the bottom of copper door frames and jambs in these areas for a long time.
4、日常保养不当
4. Improper daily maintenance
铜门在出厂前,都会有表面预氧化处理。也就是在铜板表面喷涂烘烤保护漆,以防止铜门表面氧化生锈。在正常使用情况下,如果铜门表面油漆保护层不受破坏,铜门在相当长的时间不会出现氧化生锈现象。
Copper doors undergo surface pre oxidation treatment before leaving the factory. That is to spray baking protective paint on the surface of the copper plate to prevent oxidation and rust on the surface of the copper door. Under normal usage, if the paint protective layer on the surface of the copper door is not damaged, the copper door will not experience oxidation and rust for a considerable period of time.
