id="kdpg3lx" class="box"><p><p style="text-indent:25px">鍍鋅管的保養(yǎng)技巧： 1、清水清洗清水清洗是用清水沖洗熱鍍鋅管內(nèi)壁，但是對于那些附著在鋼管內(nèi)壁的鈣鎂離子垢、生物粘泥等雜質(zhì)是不能徹底清理的，效果不明顯。 2、藥劑清洗藥劑清洗是在水中加入化學(xué)試劑，但化學(xué)成份對鋼管具有腐蝕性，同時(shí)也縮短了鋼管的壽命，是一種涸澤而漁的做法，不可取。 3、物理式清洗現(xiàn)在市場上，此種清洗的工作原理基本上是以壓縮空氣作為動(dòng)力，利用發(fā)射器向鋼管中發(fā)射一顆大于管路內(nèi)徑的特制射彈，使其沿管路內(nèi)壁高速運(yùn)動(dòng)并充分磨擦，達(dá)到清潔管路內(nèi)壁的效果。此種方式清洗效果明顯，云南大棚鋼管廠家，對管路基本無傷害，云南大棚鋼管廠家，云南大棚鋼管廠家，是迄今較為徹底的清潔方式。鍍鋅鋼管不僅普遍應(yīng)用于室內(nèi)，而且在室內(nèi)也得到普遍應(yīng)用。云南大棚鋼管廠家</p><div

style="text-indent:25px">如果熱鍍鋅管生銹該怎么處理修補(bǔ)？如果銹蝕不比較嚴(yán)重，可先用極細(xì)的水砂紙蘸水輕輕磨去銹斑，但切忌無方向地亂磨，要同向直線打磨。等完全擦凈后，涂上一層錠漆。若是新的刮傷，可擦凈后直接涂上底漆。之后，如果車輛配有小罐原廠漆，就可以等底漆干了后，再用水砂紙將其磨平，在底漆之上把原廠漆涂上。如果沒有原廠漆，可以購買一支補(bǔ)漆筆，用補(bǔ)漆筆進(jìn)行上色處理。這樣的處理雖然沒有去美容店處理效果好，但如果是小的或者不醒目處的傷痕，也可以起到防止銹跡擴(kuò)大、加重的作用。云南大棚鋼管廠家如何提高鍍鋅管的使用性能：要保證底層儲(chǔ)存時(shí)間，還要保證一定的通風(fēng)，這樣才能保證鍍鋅管不發(fā)生反應(yīng)。</p><div

style="text-indent:25px">鍍鋅管的鋅鍍層的使用溫度不得超過2500C,在此溫度上鋅結(jié)晶組織變形，發(fā)脆，耐蝕性下降。有耐蝕，耐熱要求的零件宜用Zn-Ni合金層。鍍鋅電解液可分為堿性和弱酸性兩大類，國內(nèi)外常用的有無氰鋅酸鹽鍍鋅，**鍍鋅，銨鹽鍍鋅，氯化物鍍鋅，硫酸鹽鍍鋅等。就國內(nèi)而言，無氰鋅酸鹽鍍鋅仍是主流。近年來由于鍍鋅添加劑的性能的改進(jìn)提高，氯化物鍍鋅和低氰光亮鍍鋅發(fā)展較快，而銨鹽鍍鋅在繼續(xù)下降。選擇鍍液要根據(jù)鍍件材質(zhì)，形狀，外觀要求而定，如沖壓小件和復(fù)雜件，特別是需要輔**極的深孔或管狀件宜選用堿性鍍液﹔對氫脆敏感的零件宜用弱酸性鍍鋅液。當(dāng)采用兩種性能不同的鍍液時(shí)，對鍍鋅管生產(chǎn)十分有利。</p><p style="text-indent:25px">鍍鋅管屬有色金屬，附著力比較差，涂刷醇酸類油漆，不只會(huì)發(fā)作皂化反響，還會(huì)形成原有的鍍鋅層遭到損壞，導(dǎo)致涂層失效。要想在鍍鋅方管外表涂刷防腐防銹漆，需求選用適合的底漆和面漆配套，才干真實(shí)起到防腐和裝修效果。其次，一些油脂類涂料或醇酸涂料盡管涂裝后成膜了，可是氧化反響并未中止，反響中會(huì)發(fā)生一些能與鋅反響的物質(zhì)（醛和蟻酸等），使得涂層與鋅層間發(fā)生一些疏松的物質(zhì)（蟻酸鋅），然后導(dǎo)致涂層掉落，掉落的涂層反面可見白色物質(zhì)即為蟻酸鋅。鍍鋅外表做油漆附著力比較一般的碳鋼要差許多，涂裝調(diào)和漆、醇酸漆、硝基漆乃至部分以附著力強(qiáng)而著稱的環(huán)氧漆，都會(huì)呈現(xiàn)附著力較差的狀況，形成成片掉落的現(xiàn)象。該漆可作為鍍鋅鋼結(jié)構(gòu)的外表處理底漆，即經(jīng)過涂裝該漆，可獲得一個(gè)適合涂裝大部分油漆的外表，替代傳統(tǒng)的磷化工序，現(xiàn)在一些鍍鋅鋁外表油漆歸于這種。醇酸漆、環(huán)氧漆、聚氨酯漆等均可在涂裝過磷化底漆或鍍鋅鋁外表油漆的外表覆涂。熱鍍鋅管具有涂層均勻、附著力強(qiáng)、使用壽命長等優(yōu)點(diǎn)。</p><div

style="text-indent:25px">鍍鋅管防腐鋅比鐵有還負(fù)的電極電位，當(dāng)鋅和鐵構(gòu)成微電池時(shí)，鋅為陽極，鐵為陰極，在遭到腐蝕時(shí)，鋅溶解而鐵不受危害。鍍鋅層有小的裂紋或損壞時(shí)，鋅將以獻(xiàn)身陽極的形式以免繼續(xù)裂紋或損壞處的鋼鐵生銹，這是鍍鋅層比其他涂鍍層不錯(cuò)的主要特點(diǎn)。熱鍍鋅管浸鍍鋅時(shí)，鋅鐵合金層與鋼鐵基體、鋅層之間均為冶金結(jié)合，比漆類與鋼鐵的結(jié)合還結(jié)實(shí)。鍍鋅管防腐鋅層對鋼鐵有屏蔽保護(hù)作用。鋅在大氣或其它環(huán)境下在鋼鐵基體外表形成屏蔽層。鋅的腐蝕過程增加了其形成屏蔽層的能力，這是因?yàn)殇\和空氣中的氧、二氧化碳、潮氣等反應(yīng)，生成一種抗腐蝕副產(chǎn)物堿式碳酸鋅膜。介于基體與純鋅層之間的鋅鐵合金層含鋅在90%，對鋼有與鋅近似的電化學(xué)保護(hù)作用；鍍層越厚，經(jīng)用年限也越長，經(jīng)用年限與厚度基本成正比。熱鍍鋅管清洗是非常必要的。云南大棚鋼管廠家</p><p
