鍍鋅圓管鍍鋅特點(diǎn)要求，鍍鋅圓管鋅鍍層的外觀呈青白色，標(biāo)準(zhǔn)電極電位為-0.76V，易溶于酸，溶于堿，是典型的兩性金屬。鋅在干燥空氣中幾乎不發(fā)生變化，鋅腐蝕的臨界濕度大于70%，因此在潮濕大氣中能與二氧化碳和氧作用生成一層主要由堿式碳酸鋅組成的薄膜，這層膜有一定的緩蝕作用，鋅與硫化氫等含硫化物起反應(yīng)生成硫化鋅﹔鋅易受氯離子浸蝕，故在海水中不穩(wěn)定。 </p> <p> 鍍鋅圓管的鋅在密閉或通風(fēng)不良，空氣潮濕的條件下，與非金屬材料的揮發(fā)物(低分子羧酸，醛，酚，氨等)接觸時(shí)，鋅易遭腐蝕，生成白色疏松的腐蝕產(chǎn)物，俗稱”白霜”。鋅在高溫，高濕，密閉條件下，與膠木，油漆，木材釋放的揮發(fā)物接觸，鋅有生長(zhǎng)細(xì)絲狀單晶的傾向，俗稱”長(zhǎng)毛”
