熱鍍鋅的合金層專業螺旋鍍鋅風管的厚度主要取決了鋼材的硅含量等化學成份，鋼材的橫截面積大小，鋼材表面的螺旋鍍鋅風管安裝粗糙程度(du)(du)，鋅(xin)(xin)(xin)(xin)鍋溫度(du)(du)，浸(jin)鋅(xin)(xin)(xin)(xin)時(shi)間，冷卻快(kuai)慢，冷軋變形等。 鍍鋅(xin)(xin)(xin)(xin)圓法蘭優(you)點： 1、 處(chu)理費(fei)(fei)用低：熱浸(jin)鍍鋅(xin)(xin)(xin)(xin)防(fang)銹的(de)(de)費(fei)(fei)用要(yao)比(bi)其他(ta)漆料涂層(ceng)(ceng)的(de)(de)費(fei)(fei)用低； 2、 持久耐用：在郊區(qu)環境下，標準的(de)(de)熱鍍鋅(xin)(xin)(xin)(xin)防(fang)銹的(de)(de)厚度(du)(du)，可(ke)保持50年(nian)以(yi)上而不必修補(bu)(bu)；在市(shi)區(qu)或(huo)近海區(qu)域，標準的(de)(de)熱鍍鋅(xin)(xin)(xin)(xin)防(fang)銹層(ceng)(ceng)則可(ke)保持20年(nian)而不必修補(bu)(bu)； 3、 可(ke)靠性好：鍍鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)與鋼(gang)材間是冶(ye)(ye)金結(jie)合(he)，成為鋼(gang)表面(mian)的(de)(de)一(yi)(yi)(yi)部份，因此鍍層(ceng)(ceng)的(de)(de)持久性較為可(ke)靠； 4、 鍍層(ceng)(ceng)的(de)(de)韌(ren)性強：鍍鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)形成一(yi)(yi)(yi)種(zhong)特別的(de)(de)冶(ye)(ye)金結(jie)構，這(zhe)種(zhong)結(jie)構能承受(shou)(shou)在運(yun)送及(ji)使用時(shi)受(shou)(shou)到機(ji)械損(sun)傷； 5、 全面(mian)性保護(hu)：鍍件的(de)(de)每一(yi)(yi)(yi)部分(fen)都(dou)能鍍上鋅(xin)(xin)(xin)(xin)，即使在凹陷處(chu)、尖角及(ji)隱藏處(chu)都(dou)能全面(mian)地受(shou)(shou)到保護(hu)； 6、 省(sheng)時(shi)省(sheng)力：鍍鋅(xin)(xin)(xin)(xin)過(guo)程要(yao)比(bi)其他(ta)涂層(ceng)(ceng)的(de)(de)施工法更快(kuai)捷，并且可(ke)避免安裝(zhuang)后在工地上涂刷(shua)所需的(de)(de)時(shi)間。

在目前的社專業螺旋鍍鋅風管會發展的大潮中，新的行業已經是不斷涌現，而一些舊的行而漸漸式微直到銷聲匿跡，從業者螺旋鍍鋅風管安裝也不得(de)不重新尋找其他行業的發(fa)展(zhan)機(ji)會。白鐵加工卻不同(tong)，它在時代發(fa)展(zhan)的潮流中留存了(le)(le)下來并獲(huo)得(de)一(yi)定的發(fa)展(zhan)，這(zhe)就(jiu)明(ming)顯的表明(ming)了(le)(le)一(yi)個(ge)道理(li)，那就(jiu)是(shi)黑白鐵加工行業在現代社(she)會還有市(shi)(shi)場，或者就(jiu)是(shi)該行業在發(fa)展(zhan)中轉型成功，并已經找到(dao)了(le)(le)更為廣闊(kuo)的新市(shi)(shi)場。

如果是管道外專業螺旋鍍鋅風管表面很輕微的破損，可以用專用的密封膠帶來進行修補即可。如果是管道內表面有輕微破損，則螺旋鍍鋅風管安裝可(ke)用舒伯(bo)專用修(xiu)補(bu)(bu)膠(jiao)進(jin)行(xing)修(xiu)補(bu)(bu)。如果管(guan)道(dao)外表(biao)面(mian)的鋁箔(bo)層發(fa)生破(po)(po)(po)損，而玻(bo)(bo)(bo)纖保(bao)(bao)溫層未發(fa)生損壞，則可(ke)選用一片(pian)合格的鋁箔(bo)片(pian)進(jin)行(xing)管(guan)道(dao)鋁箔(bo)表(biao)面(mian)的修(xiu)補(bu)(bu)。如果管(guan)道(dao)壁的破(po)(po)(po)損已達(da)到玻(bo)(bo)(bo)纖保(bao)(bao)溫層時，則可(ke)將破(po)(po)(po)損的地方(fang)切(qie)割下(xia)來，開出雌雄搭接(jie)口(kou)(kou)，另選一塊完(wan)好(hao)的板材，根據切(qie)割下(xia)來的玻(bo)(bo)(bo)板尺(chi)寸(cun)切(qie)割好(hao)，留下(xia)雌雄搭接(jie)口(kou)(kou)，在四周接(jie)口(kou)(kou)上(shang)涂(tu)上(shang)修(xiu)補(bu)(bu)膠(jiao)及粘膠(jiao)劑，根據工藝(yi)規范(fan)進(jin)行(xing)密封。如果管(guan)道(dao)的破(po)(po)(po)損比(bi)較嚴重，且破(po)(po)(po)損面(mian)積比(bi)較大，有可(ke)能(neng)會影響通(tong)風(feng)管(guan)道(dao)系統的正常(chang)運(yun)行(xing)時，就需(xu)要(yao)對管(guan)道(dao)進(jin)行(xing)更換(huan)修(xiu)補(bu)(bu)，以保(bao)(bao)證系統的正常(chang)運(yun)行(xing)。
