熱鍍鋅方管：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。熱鍍鋅是先將方管進(jìn)行酸洗，為了去除方管表面的氧化鐵，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(zhǎng)等優(yōu)點(diǎn)。熱鍍鋅方管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反鍍鋅方管應(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、方管基體融為一體。故其耐腐蝕能力強(qiáng)。 </p><p> 熱鍍鋅方管鑒別好壞的方法： </p> <p> 熱鍍鋅方管易出現(xiàn)折疊。折疊是熱鍍鋅方管表面形成的各種折線，這種缺陷往往貫穿整個(gè)產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時(shí)就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會(huì)開裂，鋼材的強(qiáng)度大下降。 </p> <p> 熱鍍鋅方管外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起鋼材表面不規(guī)則的凹凸不平的缺陷。由于熱鍍鋅方管廠家要追求利潤(rùn)，經(jīng)常出現(xiàn)軋槽軋制超標(biāo)。 </p> <p> 熱鍍鋅方管表面易產(chǎn)生結(jié)疤。原因有兩點(diǎn)：(1)．熱鍍鋅方管材質(zhì)不均勻，雜質(zhì)多。(2)。廠家導(dǎo)衛(wèi)設(shè)備簡(jiǎn)陋，容易粘鋼，這些雜質(zhì) </p> <p> 材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過程中由于受到熱應(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過軋制后就有裂紋。 </p> <p> 熱鍍鋅方管容易刮傷，原因是熱鍍鋅方管廠家設(shè)備簡(jiǎn)陋，易產(chǎn)生毛刺，刮傷鋼材表面。深度刮傷降低鋼材的強(qiáng)度。 </p> <p> 熱鍍鋅方管無金屬光澤，呈淡紅色或原因有兩點(diǎn)二、它的坯料是土坯。材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過目測(cè)的，這樣無法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，鋼材的性能自然就無法達(dá)標(biāo)。 </p> <p> 熱鍍鋅方管的橫筋細(xì)而低，經(jīng)常出現(xiàn)充不滿的現(xiàn)象，原因是廠家為大的負(fù)公差，成品前幾道的壓 </p> <p> <br /> 云南熱鍍鋅方管哪家好，云南贛僑鋼材廠家供應(yīng)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

<p> 1、有條件的，可以對(duì)鍍鋅方管磷化處理，或者先薄噴一層磷化底漆。 </p> <p> 2、或者對(duì)光滑的鍍鋅方管表面掃砂處理。 </p> <p> 3、對(duì)鍍鋅工件、鍍鋅方管表面用溶劑（即環(huán)氧鋅黃底漆稀釋劑）擦拭，以去除工件原油的保護(hù)層，并且增加潔凈度。 </p> <p> 4、雙組份環(huán)氧鋅黃底漆：嚴(yán)格按照漆和固化劑的比例調(diào)配油漆，并且熟化30分鐘后，調(diào)制合適的施工粘度，即可噴涂。 </p> <p> 單組份環(huán)氧酯鋅黃底漆：調(diào)制合適的施工粘度，以正確的施工方法施工。 </p> <p> <br /> 為提高的耐腐蝕性能，對(duì)一般方管（黑管）進(jìn)行鍍鋅。昆明經(jīng)開區(qū)***熱鍍鋅方管哪家好</p><p style="text-indent:25px">什么是熱鍍鋅方管？？昆明經(jīng)開區(qū)薄壁熱鍍鋅方管市場(chǎng)行情</p><p> 檢測(cè)熱鍍鋅方管表面缺陷的方法： </p> <p> 磁粉法檢測(cè)：磁粉法檢測(cè)的原理是在方管材料中實(shí)現(xiàn)磁場(chǎng)，根據(jù)缺陷處的漏磁場(chǎng)與磁粉的相互作用，當(dāng)表面和近表面有不連續(xù)或缺陷時(shí)，則在不連續(xù)處或缺陷處磁力線發(fā)生局部畸變產(chǎn)生磁極。其優(yōu)點(diǎn)是設(shè)備投資少，可靠性高，具有直觀性。缺點(diǎn)是操作成本高，不能對(duì)缺陷準(zhǔn)確分類，檢測(cè)速度較低。 </p> <p> 四紅外線檢測(cè)：通過高頻感應(yīng)線圈，在方管表面產(chǎn)生感應(yīng)電流，感應(yīng)電流會(huì)導(dǎo)致缺陷區(qū)域消耗更多電能，引起局部溫度升高，通過紅外線檢測(cè)局部溫度，從而確定缺陷深度。紅外線檢測(cè)一般用于平直表面的缺陷檢測(cè)，不適合檢測(cè)表面不平整金屬。 </p> <p> 漏磁檢測(cè)：方管的漏磁檢測(cè)方法和磁粉檢測(cè)方法非常相似，適用范圍、靈敏度和可靠性較磁粉檢測(cè)方法更強(qiáng)。昆明經(jīng)開區(qū)薄壁熱鍍鋅方管市場(chǎng)行情</p><p
