      導致斷橋鋁門窗設備腐蝕的天氣的因素

      2018-03-01 點擊數:981
      1、大氣污染
      1. Air pollution
      正常情況下,空氣中的腐蝕介質很少,只有氧對金屬的腐蝕是經常性的(平日里我們鋁合金門窗設備和斷橋鋁門窗設備的床身就是通過氧化,來達到時效處理的效果),但隨著各國工業企業的不斷發展,空氣中的有害氣體和粉塵也大量增加,如煤、煤油、柴油燃燒后生成的二氧化碳、二氧化硫等氣體。還有大量的塵埃,如煙霧、煤灰、氯化物和其他酸、堿、鹽顆粒等也散布到大氣中,有的本身就具有腐蝕性,有的是凝在水珠中對金屬具有腐蝕作用。
      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、溫度

      2. Temperature

      高溫高濕時,氣溫升高加速腐蝕。溫度交變由高溫驟降時,使大氣中的水汽凝聚成膜,也可加速腐蝕過程。潮濕時間逾長,腐蝕也愈嚴重。一般講晝夜溫差大于6℃,氣溫在5℃~50℃的范圍內變化時,只要相對濕度達到65%-75%就會出現凝霧現象。
      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、濕度
      3. Humidity
      由于空氣中的水分凝聚成液態水膜是形成腐蝕原電池的必要條件,因此空氣的濕度是主要因素,當濕度達到某一臨界值時表面形成水膜,腐蝕速度加劇。
      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.
