冷鍍鋅也叫電鍍鋅,是利用電解設備將管件經過除油、酸洗、後放入成分為鋅鹽的溶液中,並連接電解設備的負極,在管件的對面放置鋅版,連接在電解設備的正極接通電源,利用電流從正極向負極的定向移動就會在管件上沉積一層鋅,冷鍍管件是先加工后鍍鋅。冷鍍鋅(電鍍鋅):是在電鍍槽內通過電流單向性使鋅逐漸鍍上金屬外表,生產速度慢,鍍層均勻,厚度較薄,通常只有3-15微米,外觀光亮、光滑、美觀度高,耐腐蝕性差,一般幾個月就會鏽蝕。
熱鍍鋅是由較古老的熱鍍方法發展而來的,自從1836年法國把熱鍍鋅應用於工業以來,已經有一百七十年的歷史了。然而,熱鍍鋅工業是近三十年來伴隨冷軋帶鋼的飛速發展而得到了大規模發展。
不同把熱鍍鋅工藝分為線外退火和線內退火兩大類,即濕法(單張鋼板熱鍍鋅法)、線外退火(單張鋼板熱鍍鋅法)、熱鍍鋅 惠林(Wheeling)法(帶鋼連續熱鍍鋅法) 、線內退火 森吉米爾(Sendzimir)法(保護氣體法)、改良森吉米爾法、美鋼聯法(同日本川崎法)、賽拉斯(Selas)法和莎倫(Sharon)法。熱鍍鋅:是在加熱融化的鋅液內浸鍍,生產速度快,鍍層厚但不均勻,市場允許的最低厚度45微米,最高可達300微米以上。顏色較暗,消耗鋅金屬多,與基體金屬形成滲入層,耐蝕性好,室外環境下熱鍍鋅可以保持幾十年。
熱鍍鋅也稱熱浸鋅,是將鋼鐵工件經過除油、除銹,呈現出無污、浸潤的表面,立即浸入到預先將鋅加熱融熔了的鍍槽中去,
在工件表面形成一層鋅鍍層的方法。冷鍍鋅則是將同樣經過了除油、除誘,呈現出無污、浸潤的工件掛入專門的電鍍槽里的陰極上,陽極用鋅。接通直流電源,陽極上的鋅離子向陰極遷移,並在陰極上放電,使工件鍍上一層鋅層的熱鍍鋅方法。
熱鍍鋅的鍍層較厚,一般為30-60微米,鍍層防腐能力較高。適合於戶外工作的鋼鐵製件,如高速公路圍欄、電力鐵塔、大尺寸緊固件等較為“粗糙”的工件的長期防鏽。
熱鍍鋅絲:該產品應用優質碳素結構鋼,經拉拔、熱鍍鋅加工而成。廣泛應用於製造金屬絲網、高速公路護攔及建築工程。具有鍍層厚,抗腐蝕能力強、鍍層牢固等特點。並可根據用戶的特殊需求,按行業標準提供各種規格的鍍鋅絲。
相對電鍍鋅,熱鍍鋅生產成本較高但對環境的影響比電鍍小。
物理性能:熱鍍鋅鋼絲表面平滑、光潔、沒有裂紋地、節、起刺、傷痕和鏽蝕,鍍鋅層均勻、附著力強、耐腐蝕力持久,韌性和彈性極好。抗拉強度應在900Mpa-2200Mpa之間(絲徑Φ0.2mm-Φ4.4mm)。扭轉次數(Φ0.5mm)在20次以上,反覆彎曲應在13次以上。

So hot dip galvanizedandgalvanized ironwhat is the difference?
