熱鍍鋅也稱熱浸鍍鋅，是鋼鐵構(gòu)件浸入熔融的鋅液中獲得金屬覆蓋層的一種方法。近年來隨高壓輸電、交通、通訊事業(yè)迅速發(fā)展，對鋼鐵件防護(hù)要求越來越高，熱鍍鋅需求量也不斷增加。2熱鍍鋅層防護(hù)性能通常電鍍鋅層厚度5～15μm，而熱鍍鋅層一般在35μm以上，甚至高達(dá)200μm。熱鍍鋅覆蓋能力好，鍍層致密，無有機(jī)物夾雜。眾所周知，鋅的抗大氣腐蝕的機(jī)理有機(jī)械保護(hù)及電化學(xué)保護(hù)，在大氣腐蝕條件下鋅層表面有ZnO、Zn(OH)2及堿式碳酸鋅保護(hù)膜，一定程度上減緩鋅的腐蝕，這層保護(hù)膜(也稱白銹)受到破壞又會形成新的膜層。當(dāng)鋅層破壞嚴(yán)重，危及到鐵基體時，鋅對基體產(chǎn)生電化學(xué)保護(hù)，鋅的標(biāo)準(zhǔn)電位，鐵的標(biāo)準(zhǔn)電位，鋅與鐵形成微電池時鋅作為陽極被溶解，鐵作為陰極受到保護(hù)。顯然熱鍍鋅對基體金屬鐵的抗大氣腐蝕能力優(yōu)于電鍍鋅。3熱鍍鋅層形成過程熱鍍鋅層形成過程是鐵基體與外面的純鋅層之間形成鐵-鋅合金的過程，工件表面在熱浸鍍時形成鐵-鋅合金層，才使得鐵與純鋅層之間很好結(jié)合，其過程可簡單地?cái)⑹鰹椋寒?dāng)鐵工件浸入熔融的鋅液時，首先在界面上形成鋅與α鐵(體心)固熔體。官渡區(qū)鍍鋅圓管昆明鍍鋅圓管，云南贛僑貿(mào)易供應(yīng)。</p><div

style="text-indent:25px">常說的鍍鋅圓管，煤氣、暖氣用的那種鐵管也是鍍鋅圓管，鍍鋅圓管作為水管，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。先利用溶劑清洗鋼材表面，把表面的有機(jī)物去除，然后使用工具除銹（鋼絲刷）,去除松動或傾斜的規(guī)模，鐵銹，焊渣等,使用酸洗的方式。鍍鋅分為熱鍍和冷鍍，熱鍍不易生銹，冷鍍較易生銹。鍍鋅圓管管口對接后出現(xiàn)兩支管口對接不嚴(yán)現(xiàn)象，導(dǎo)致焊口薄厚不均勻；以及鋼管由于本身原因或運(yùn)輸磕碰，造成管口橢圓，建議將鋼管管頭截掉一小段兒后再進(jìn)行加工。熱鍍鋅圓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。熱鍍鋅圓管是先將鋼管進(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。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>鍍鋅鋼管主要特點(diǎn)： <p> 1、鋅鍍層比較厚，鐵—鋅合金層，結(jié)合致密，勻稱且無孔隙度，抗腐蝕性好； </p> <p> 2、因?yàn)殇\鍍層具備杰出的延展性，因此可進(jìn)行冷沖、軋制、折彎等各種成型而不破壞鍍層。 </p> <p> 3、鋼結(jié)構(gòu)件熱鍍鋅后，相當(dāng)于一次退火處理，能有效改進(jìn)鋼基體的機(jī)械功能，消除鋼件成型焊接時的應(yīng)力，有助于對鋼結(jié)構(gòu)件進(jìn)行車削加工。 </p> <p> 4、具備比較厚的致密的純鋅層掩蓋在鋼鐵表面上，它能夠避免鋼鐵基體與任何的腐蝕溶液的觸摸，維護(hù)鋼基體免遭腐蝕。 </p> <p> 5、鋅鍍層經(jīng)鉻酸鈍化后形成白色、五顏六色、軍綠色等，漂亮大方，具備必定的裝飾性； </p> <p> 6、熱鍍鋅后的件表面亮光美觀漂亮。 </p> <p> 以上六點(diǎn)就是鍍鋅鋼管的主要特點(diǎn)，希望通過上面的內(nèi)容可以幫助到大家。目前消防給水管道基本上是鍍鋅管，鍍鋅管外層涂有油漆，其實(shí)它們只是經(jīng)過鍍鋅圓管加工而成。</p><div

</p> <p> 1、鍍鋅層的均勻性:鋼管試樣在硫酸銅溶液中連續(xù)浸漬5次不得變紅(鍍銅色) </p> <p> 2、表面質(zhì)量:鍍鋅鋼管的表面應(yīng)有完整的鍍鋅層，不得有未鍍上的黑斑和氣泡存在，允許有不大的粗糙面和局部鋅瘤存在。 </p> <p> 3、鍍鋅層重量:根據(jù)需方要求，鍍鋅鋼管可作鋅層重量測定，其平均值應(yīng)不小于500g/平方米，其中任何試樣不得小于480g/平方米。現(xiàn)在使用的鍍鋅圓管是熱浸鍍鋅的，而用于電氣目的的線槽是冷浸鍍鋅的。官渡區(qū)國標(biāo)鍍鋅圓管價(jià)格咨詢</p><p
