1、觀(guān)察濟南鋁板http://www.24276.cn/顏色,已生成氧化膜的純鋁板表面是乳白色,鑄鋁,雜鋁呈灰黑色。未生成氧化膜的表面呈透明的亮白色,有的還附有粉紅或灰黑色的掛霜。
Jinan observed aluminum color, has generated pure aluminum oxide film surface is white, cast aluminum, aluminum miscellaneous grayish black. Did not generate a transparent oxide film surface was bright white, some gray with pink or black frost.
  
2、測量濟南鋁板電阻,已生成氧化膜的檢測時(shí)有電阻,常壓下不導電,未生成氧化膜的檢測時(shí)能導電。
Jinan aluminum measuring resistance, the generated oxide film has resistance detected when non-conductive under normal pressure, can be detected when the conductive oxide film is not generated.
  
3、劃痕,已生成氧化膜的濟南鋁板表面很硬,用針劃時(shí)打滑,無(wú)劃痕,未生成氧化膜的表面很軟,用針劃時(shí)有阻力和劃痕。
Scratches, Jinan generated aluminum oxide film surface is very hard, when you draw with a needle slipping, no scratches, no surface oxide film is very soft, there is resistance and scratches with a needle scratch.
  
4、聽(tīng)聲,已生成氧化膜的濟南鋁板敲打時(shí)會(huì )發(fā)出清脆聲,未生成氧化膜的敲打時(shí)發(fā)出悶聲。
Listen to the sound, it will issue a crisp sound generated when the aluminum oxide film Jinan beat, beat of the oxide film at issue did not generate muffled.
  
5、對濟南鋁板http://www.24276.cn/進(jìn)行著(zhù)色檢驗,已生成氧化膜的在染色溶液中很快可以上色,未生成氧化膜的在染料溶液中染不上色。
Jinan colored aluminum plate test, the generated oxide film may be colored in a dye solution quickly, the oxide film is not generated in the dye solution, dye not color.
