鍍鋅槽鋼按鍍鋅工藝的不同可以分為熱浸鋅槽鋼和熱吹鍍鋅槽鋼，是將除銹后的鋼件浸入440~460℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。在日常的使用中經(jīng)常會發(fā)生生銹的現(xiàn)象，那么要如何防止其生銹呢？下面鍍鋅槽鋼廠家為您講解： </p> <p> 一、在各種保護鍍鋅槽鋼的涂鍍方法中，熱浸鋅是非常優(yōu)良的一種。它是在鋅呈液體的狀態(tài)下，經(jīng)過了相當(dāng)復(fù)雜的物理、化學(xué)作用之后，在鋼鐵上不僅鍍上較厚的純鋅層，而且還生成一種鋅鐵合金層。這種鍍法，不僅具備了電鍍鋅的耐腐蝕特點，而且由于具有鋅鐵合金層。還具有電鍍鋅所無法相比擬的強耐蝕性。 </p> <p> 二、鍍鋅會延緩鍍鋅槽鋼的生銹時間，延緩的時間取決于鍍鋅的質(zhì)量（預(yù)先的除銹處理，鍍鋅層厚度等），安裝質(zhì)量（預(yù)先鍍鋅的材料加工后是否補鋅或補漆處理）和安裝的環(huán)境（環(huán)境是否潮濕，是否在海邊戶外的咸濕環(huán)境中等）。昆明熱鍍鋅槽鋼供應(yīng)熱鍍鋅槽鋼產(chǎn)品表面光滑，無漏鍍,無疤點，鋅層均勻，附著能力強。</p><div

鍍鋅槽鋼的序號越高，黏度越大，閃點就越高。一般閃點在150～300℃之間。槽鋼在熱處理時油的閃點是指油表面的蒸氣和空氣自然混合時，與火相接觸而出現(xiàn)火苗的溫度，它的溫度的高低，對淬火零件的安全性有一定的影響。 </p> <p> 無論通過何種途徑實現(xiàn)復(fù)合鑄造，槽鋼在使用前都需經(jīng)淬火處理以充分發(fā)揮頭部金屬的耐磨性。不同于單一材質(zhì)錘頭的是，雙金屬復(fù)合錘頭的結(jié)合部位會因兩種金屬的收縮率不同而在淬火時產(chǎn)生更大的應(yīng)力，因此淬火后進行回火是十分必要的。 </p> <p> 由上可知，槽鋼的鑄造是提高鑄件整體性能重要而有效的手段，不同金屬間的結(jié)合既可以是機械結(jié)合又可以是冶金結(jié)合。機械結(jié)合錘頭在生產(chǎn)中常出現(xiàn)裂紋和氣孔等缺陷，可采取簡單方法予以避免；而冶金結(jié)合錘頭則需解決好截面問題。后者具有比前者更加優(yōu)良的綜合性能，但生產(chǎn)工藝較復(fù)雜且對生產(chǎn)過程控制的要求更為嚴(yán)格。 </p><p> 所謂堅實性就是鍍鋅層與槽鋼密合性，主要要求鍍鋅構(gòu)件在整理、運搬、保管及使用中具有不得剝離的性質(zhì)，一般檢驗法有錘打法、擠曲法、卷附法等。錘打法是以錘打擊試片，檢查鍍鋅槽鋼鍍層皮膜表面的狀態(tài)。把試片固定，免得因錘支持臺等高且水平，錘以支持臺為中心，使柄重垂直位置自然落下，以4mm間隔平行打擊5點，觀察皮膜是否剝離以為判斷。但是，距離角或端10mm以內(nèi)，不得作此試驗，同一處不可打擊2次以上等。此法普遍，適用于鋅、鋁等皮膜堅實測試。其它如擠曲法、卷附法一般很少用，故暫且不提。一般人常有一種錯誤觀念，往往為了方便量測堅實性，拿兩個鍍鋅鋼材，以邊角互相敲擊，觀察邊角剝落情形以為判斷。若邊角處剛好有幾處較厚的鋅粒。在作業(yè)中沒處理好，則一用力敲擊，厚的鋅粒一定會剝落。故此法不能用來判定正常鍍鋅皮膜與鐵基的密合性。 </p> <p> 附著量、均一性及堅實性，即為一般規(guī)格定義熱浸鍍鋅質(zhì)量檢驗的項目。亦是一般正式檢驗報告的標(biāo)準(zhǔn)。云南鍍鋅槽鋼廠家，昆明鋼好物資供應(yīng)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

鍍鋅槽鋼的防銹效果要看你鍍鋅層的厚度以及鍍鋅層的鈍化效果，在前處理以及電鍍過程都沒有問題的情況下，合理選擇電鍍的類型（鍍彩鋅、鍍白鋅等等），鍍鋅層越厚，防銹期就會越長，同樣，鈍化效果也是非常關(guān)鍵的。 </p> <p> 鍍鋅槽鋼因為鍍層的原因比一般的槽鋼防腐蝕能力強，但是如果鍍層老化氧化脫落之后，里層金屬很容易會被大氣酸性物質(zhì)腐蝕而生銹。因此需要放在陰涼通風(fēng)處，采用Rustoper防銹包裝材料或者防銹劑進行保護，先是把鐵和腐蝕介質(zhì)隔開；如果有部分裸露，由于鐵和鋅的電勢不同，形成腐蝕原電池，而鋅作為優(yōu)先被氧化。鍍鋅槽鋼的堅實性就是鍍鋅層與鋼鐵密合性。昆明熱鍍鋅槽鋼供應(yīng)</p><p
