熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中，昆明國標(biāo)鍍鋅圓管廠家直銷。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長等優(yōu)點(diǎn)。 </p> <p> 冷鍍鋅管 </p> <p> 冷鍍鋅就是電鍍鋅，鍍鋅量很少，只有10－50g/m2，其本身的耐腐蝕性比熱鍍鋅管相差很多。正規(guī)的鍍鋅管生產(chǎn)廠家，為了保證質(zhì)量，大多不采用電鍍鋅（冷鍍）。只有那些規(guī)模小、設(shè)備陳舊的小企業(yè)采用電鍍鋅，當(dāng)然他們的價格也相對便宜一些。目前建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，昆明國標(biāo)鍍鋅圓管廠家直銷，今后不準(zhǔn)用冷鍍鋅管作水，昆明國標(biāo)鍍鋅圓管廠家直銷、煤氣管。

鍍鋅圓管的外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起圓管表面不規(guī)則的凹凸不平的缺陷。由于偽劣圓管廠家要追求利潤，經(jīng)常出現(xiàn)軋槽軋制。所以在日常中要注意購買，以免買到假的圓管，下面圓管廠家為您講解選購的方法： </p> <p> 1、偽劣鍍鋅圓管的材質(zhì)含雜質(zhì)多，圓管的密度偏小，而且尺寸差嚴(yán)重，所以在沒有游標(biāo)卡尺的情況下，可以對它進(jìn)行稱量核對。 </p> <p> 2、更準(zhǔn)確的搜索是在鍍鋅圓管前加上地名,如昆明鋼好鍍鋅圓管,這樣的搜索結(jié)果有利于就近采購，量大也可以實(shí)地去考察。 </p> <p> 3、如果買家對所購材料有意向性,可直接在搜索引擎上輸入"材質(zhì) 圓管"這樣組合的關(guān)鍵詞,如***鍍鋅圓管等.... </p> <p> 4、在選擇鍍鋅圓管的時候，肯定是要對它的硬度有所了解，因?yàn)橛捕缺容^高的鍍鋅圓管，在價格上面也是比較高的。而且一定不要圖便宜購買質(zhì)量比較差的鍍鋅圓管，不然后期出現(xiàn)的問題是非常多的，用于維修也是比較麻煩的，而且需要支付一定的維修費(fèi)用。 </p> <p> 5、鍍鋅圓管主要用于建筑結(jié)構(gòu)、幕墻工程、機(jī)械設(shè)備和車輛制造，在使用中要求其具有較好的焊接、鉚接性能及綜合機(jī)械性能。昆明國標(biāo)鍍鋅圓管廠家直銷昆明鍍鋅圓管報(bào)價，云南贛僑貿(mào)易供應(yīng)。</p><div style="width:100%;text-align: center;"><img

鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。 </p> <p> 冷鍍鋅鋼管 </p> <p> 鋅層是電鍍層，鋅層與鋼管基體**分層。鋅層較薄，鋅層簡單附著在鋼管基體上，容易脫落。故其耐腐蝕性能差。在新建住宅中，禁止使用冷鍍鋅鋼管作為給水管。 </p> <p> 鍍鋅鋼管的用途 </p> <p> 常說的鍍鋅管，鍍鋅管的用途現(xiàn)在煤氣、暖氣用的那種鐵管也是鍍鋅管，鍍鋅管作為水管，使用幾年后，管內(nèi)產(chǎn)生大量銹垢，流出的黃水不僅污染潔具，而且夾雜著不光滑內(nèi)壁滋生的細(xì)菌，銹蝕造成水中重金屬含量過高，嚴(yán)重危害人體的健康。六七十年代，國際上發(fā)達(dá)國家開始開發(fā)新型管材，并陸續(xù)禁用鍍鋅管。中國建設(shè)部等四部委也發(fā)文明確從二000年起禁用鍍鋅管，目前新建小區(qū)的冷水管已經(jīng)很少使用鍍鋅管了，有些小區(qū)的熱水管使用的是鍍鋅管。 </p> <p> <br /> </p><p style="text-indent:25px">鍍鋅圓管表面有熱浸鍍或電鍍鋅層的焊接鋼管。鍍鋅可增加鋼管的抗腐蝕能力，延長使用壽命。鍍鋅管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。尺寸標(biāo)準(zhǔn)為：DN15

為降低鋅鍍層厚又能提高耐蝕能力，國內(nèi)外采用如下兩種措施﹕一是提高鈍化膜的質(zhì)量，如用藍(lán)色，綠色，軍綠色，黑色鈍化代替常規(guī)的彩虹色鈍化膜，尤以軍綠化鈍化膜耐蝕性較好好﹔二是以較薄的含鐵0.3%--0.6%的Zn-Fe合金，或含鎳6%-10%的Zn-Ni合金代替純鋅鍍層，耐蝕性能提高三倍以上，普遍用于汽車鋼板上代替鍍鋅。昆明國標(biāo)鍍鋅圓管廠家直銷</p><p
