              濟南鋁板的質量如何判別?

              1、鋁型材及包裝上是否標有產品標準代號及生產許可證號等,濟南鋁板表面除應清潔,不允許有裂紋、起皮、腐蝕和氣泡等缺陷存在外,還不允許有腐蝕斑、電灼傷、黑斑、氧化膜脫落等缺陷。
              Are marked aluminum and packaging products standard code and production license number, etc., in addition to Jinan aluminum surface should be clean, not allowed to have cracks, peeling, corrosion and bubbles and other defects, but also does not allow corrosion spots, electrical burns , spots, and other defects in the oxide film off.

              2、濟南鋁板http://www.shopbydonnashana.com/的氧化膜是在陽極氧化中形成的,具有防護和裝飾作用,可用渦流測厚儀進行檢測。
              Jinan aluminum oxide film is formed in the anodic oxidation, with a protective and decorative effect, can be used to detect the eddy current thickness gauge.

              3、濟南鋁板http://www.shopbydonnashana.com/經陽極氧化后表面留有許多空隙,如果不進行封閉或封閉不好,將減小鋁型材的耐腐蝕性。濟南鋁板耐蝕性檢查有銅加速醋酸鹽霧試驗和滴堿試驗。
              Jinan anodized aluminum surface after leaving many gaps, if not closed or sealed well, will reduce the corrosion resistance of aluminum. Jinan check corrosion resistance of aluminum copper accelerated acetic acid salt spray test and drop test base.
