导致断桥铝门窗设备腐蚀的天气的因素

1、大气污染
1. Air pollution
正常情况下，空气中的腐蚀介质很少，只有氧对金属的腐蚀是经常性的(平日里我们铝合金门窗设备和断桥铝门窗设备的床身就是通过氧化，来达到时效处理的效果)，但随着各国工业企业的不断发展，空气中的有害气体和粉尘也大量增加，如煤、煤油、柴油燃烧后生成的二氧化碳、二氧化硫等气体。还有大量的尘埃，如烟雾、煤灰、氯化物和其他酸、碱、盐颗粒等也散布到大气中，有的本身就具有腐蚀性，有的是凝在水珠中对金属具有腐蚀作用。
Under normal circumstances, the corrosive medium in the air is very few, only the corrosion of oxygen to metal is regular (we Aluminum Alloy doors and windows equipment and aluminum doors and windows equipment bed on weekdays is through oxidation, to achieve the effect of aging treatment), but with the continuous development of industrial enterprises in various countries, also increased the amount of harmful gases and the dust in the air, such as coal, kerosene, diesel combustion generated carbon dioxide, sulfur dioxide and other gases. There are also a lot of dust, such as smoke, ash, chloride and other acids, alkalis, salt particles, and so on, which are also distributed into the atmosphere. Some of them are corrosive, others are coagulating in water droplets, which are corrosive to metals.
2、温度

2. Temperature

高温高湿时，气温升高加速腐蚀。温度交变由高温骤降时，使大气中的水汽凝聚成膜，也可加速腐蚀过程。潮湿时间逾长，腐蚀也愈严重。一般讲昼夜温差大于6℃，气温在5℃～50℃的范围内变化时，只要相对湿度达到65%-75%就会出现凝雾现象。
When the temperature is high and high, the temperature increases and the corrosion is accelerated. When temperature changes suddenly drop from high temperature, the water vapor in the atmosphere is condensed into film, and the corrosion process can also be accelerated. The longer the humid time is, the more serious the corrosion is. Generally speaking, the temperature difference between day and night is greater than 6, and the temperature is changed within the range of 5 ~ 50. As long as the relative humidity reaches 65%-75%, the phenomenon of fog will appear.
3、湿度
3. Humidity
由于空气中的水分凝聚成液态水膜是形成腐蚀原电池的必要条件，因此空气的湿度是主要因素，当湿度达到某一临界值时表面形成水膜，腐蚀速度加剧。
Because the moisture in the air condensed into liquid water film is the necessary condition to form corrosive primary battery. Therefore, the humidity of the air is the main factor. When the humidity reaches a critical value, the water film forms on the surface and the corrosion rate increases.
