怎么避免保温铝卷氧化腐蚀?
How to avoid oxidation corrosion of insulating aluminium coil?
1、车间、仓库房顶有漏雨、雪的地方,不该放置铝卷。
1. Aluminum coils should not be placed on the roofs of workshops and warehouses where there are leaks of rain and snow.
2、加强空气干燥的管理,保证压缩空气中无水。
2. Strengthen the management of air drying to ensure that there is no water in compressed air.
3、铝箔卷的包装应采用密封包装,一起每卷应放入适量的干燥剂。
3. Aluminum foil rolls should be packed in sealed packages, together with a suitable amount of desiccant for each roll.
4、由低温区运入温度高、湿度大的地区时,不要当即敞开密封包装。


4. When transporting from low temperature area to high temperature and humidity area, do not open the sealed package immediately.
5、加强轧制油的管理,其含水量控制在0.04%以下。
5. Strengthen the management of rolling oil and control its water content below 0.04%.
6、包装箱的木轴、箱板的湿度不大于18%,包装彩色铝卷的温度不大于45℃。
6. The humidity of the wooden axle and boards of the packing box is not more than 18%, and the temperature of the color aluminium coil of the packing box is not more than 45 C.
正常状况的氧化是指铝卷在使用后,例如包在管道上今后,铝卷表面会完全和空气触摸,形成一层氧化膜,这层氧化膜会维护铝卷不再进一步腐蚀,所以使用后,即便再淋雨,户外暴晒,保温铝卷也不会腐蚀。
Normal oxidation means that the surface of aluminium coil will be completely touched by air after use, such as wrapping in pipelines, forming an oxide film. This oxide film will maintain that the aluminium coil will not further corrode, so after use, even if it is rained and exposed outdoors, the insulating aluminium coil will not corrode.
