1、鋅鍍層較厚，鐵—鋅合金層，結(jié)合致密，均勻且無孔隙，抗腐蝕性好； </p> <p> 2、鋅鍍層經(jīng)鉻酸鈍化后構(gòu)成白色、五顏六色、軍綠色等，漂亮大方，具有必定的裝飾性； </p> <p> 3、因?yàn)殇\鍍層具有杰出的延展性，因而可進(jìn)行冷沖、軋制、折彎等各種成型而不損壞鍍層。 </p> <p> 4、鋼結(jié)構(gòu)件熱鍍鋅后，相當(dāng)于一次退火處理，能有用改進(jìn)鋼基體的機(jī)械功能，消除鋼件成型焊接時(shí)的應(yīng)力，有利于對鋼結(jié)構(gòu)件進(jìn)行車削加工。 </p> <p> 5、有較厚的致密的純鋅層掩蓋在鋼鐵表面上，它可以防止鋼鐵基體與任何的腐蝕溶液的觸摸，維護(hù)鋼基體免受腐蝕。 </p> <p>

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。濟(jì)寧冠翔供應(yīng)的熱鍍鋅管是先將鋼管進(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)。熱鍍鋅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)。焊接鋼管的用途有哪些？濟(jì)寧架子管批發(fā)廠家</p><p
