style="text-indent:25px">熱鍍鋅的功能①力學功能：鍍鋅使用時均需成形加工，故請求它具有必定的強度外，還應具有杰出的深沖功能。關于通常低碳緊固件選用Sendzimir法出產(chǎn)線的線內(nèi)退火達不到此請求。但關于通常輕度深沖加工的商品，可選用下降鋼帶運轉速度的辦法（即延伸其在復原爐內(nèi)的停留時刻）處理。②耐腐蝕性：鍍鋅緊固件具有杰出的耐大氣腐蝕性。這是因為鋅的電位比鐵低，鋅層對鋼基體呈陽性，鐵呈陰性。在電解液中，鋅層溶解而維護鋼基體不被腐蝕；此外，鋅層在通常的大氣環(huán)境中，其腐蝕產(chǎn)品通常為堿式碳酸鋅[ZnCO3?Zn(OH)2]，它對鋅層有必定的維護作用。但在含硫的工業(yè)大氣中，其腐蝕產(chǎn)品是易溶于水的硫酸鋅鹽，易被雨水沖刷流失，不能阻止鋅層的進一步腐蝕。因而，在工業(yè)大氣中，鋅層的腐蝕較快。③焊接功能：鍍鋅緊固件具有杰出的焊接性，可以點焊和縫焊。點焊時，其焊接強度與低碳鋼點焊挨近。但焊接電流需增大10%～15%。</p><p> 熱鍍鋅也叫熱浸鋅和熱浸鍍鋅: </p> <p> 是一種有效的金屬防腐方式, </p> <p> 主要用于各行業(yè)的金屬結構設施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中,使鋼構件表表面附著鋅層,從而起到防腐的目的。 </p> <p> 熱鍍鋅的優(yōu)點： </p> <p> 1、處理費用低:熱浸鍍鋅防銹的費用要比其他漆料涂層的費用低; </p> <p> 2、持久耐用:在郊區(qū)環(huán)境下,標準的熱鍍鋅防銹厚度可保持50年以上而不必修補;在市區(qū)或近海區(qū)域,標準的熱鍍鋅防銹層則可保持20年而不必修補; </p> <p> 3、可靠性好:鍍鋅層與鋼材間是冶金結合,成為鋼表面的一部份,因此鍍層的持久性較為可靠; </p> <p> 4、鍍層的韌性強:鍍鋅層形成一種特別的冶金結構,這種結構能承受在運送及使用時受到機械損傷; </p> <p> 5、***性保護:鍍件的每一部分都能鍍上鋅,即使在凹陷處、尖角及隱藏處都能受到***保護; </p> <p> 6、省時省力:鍍鋅過程要比其他的涂層施工法更快捷,并且可避免安裝后在工地上涂刷所需的時間。 </p> <p> 簡單一句話，提高了螺絲的性能。工業(yè)上常用的鍍鋅層有熱浸鍍鋅、電鍍鋅、機械鍍鋅和熱噴涂（鍍）鋅等。</p><div
