1、管板材的開槽

板材開(kai)(kai)槽(cao)的種(zhong)類(lei)有三種(zhong)：一塊板開(kai)(kai)槽(cao)法、二(er)塊板開(kai)(kai)槽(cao)法、四塊板開(kai)(kai)槽(cao)法。板材開(kai)(kai)槽(cao)的方法有兩(liang)種(zhong)：手工開(kai)(kai)槽(cao)法、機械開(kai)(kai)槽(cao)法。

2、密封

節能消音通風管道系統(tong)建議使(shi)用的(de)密(mi)封(feng)膠(jiao)帶(dai)有(you)：熱敏膠(jiao)帶(dai)、壓敏膠(jiao)帶(dai)兩(liang)種。在管道未用膠(jiao)帶(dai)密(mi)封(feng)前，應先(xian)使(shi)用專用的(de)扒(ba)形裝(zhuang)(zhuang)訂(ding)(ding)針，對管道的(de)搭(da)接(jie)口進行固定(ding)，裝(zhuang)(zhuang)訂(ding)(ding)針的(de)間距為(wei)(wei)50mm一(yi)個。裝(zhuang)(zhuang)訂(ding)(ding)時，裝(zhuang)(zhuang)訂(ding)(ding)針應與(yu)接(jie)縫略(lve)呈角度(du)。裝(zhuang)(zhuang)訂(ding)(ding)針僅用于(yu)有(you)蓋(gai)舌的(de)搭(da)接(jie)口固定(ding)，若無(wu)蓋(gai)舌，或平(ping)接(jie)口時，應用膠(jiao)帶(dai)接(jie)片進行固定(ding)，膠(jiao)帶(dai)為(wei)(wei)300mm，每邊(bian)至少1個。

3、加固

當通風管道系統內部的靜壓負載使白鐵皮風管道(dao)(dao)管(guan)(guan)(guan)(guan)道(dao)(dao)壁出現1％的(de)撓度(du)時，就需要對(dui)通(tong)風(feng)管(guan)(guan)(guan)(guan)道(dao)(dao)管(guan)(guan)(guan)(guan)道(dao)(dao)進行加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)。通(tong)常(chang)節能消音通(tong)風(feng)管(guan)(guan)(guan)(guan)道(dao)(dao)系統管(guan)(guan)(guan)(guan)道(dao)(dao)可采(cai)用(yong)(yong)(yong)(yong)以下(xia)方(fang)法來(lai)進行加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)：a.拉(la)(la)桿加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)法，它是采(cai)用(yong)(yong)(yong)(yong)鋼(gang)(gang)彩、套管(guan)(guan)(guan)(guan)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)，通(tong)常(chang)使用(yong)(yong)(yong)(yong)在500Pa以下(xia)的(de)正(zheng)壓加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)。b.框架(jia)(jia)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)法，即(ji)采(cai)用(yong)(yong)(yong)(yong)輕鋼(gang)(gang)龍骨加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)。c.抱合加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)法，即(ji)采(cai)用(yong)(yong)(yong)(yong)輕鋼(gang)(gang)龍骨加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)，使用(yong)(yong)(yong)(yong)在拉(la)(la)桿加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)和框架(jia)(jia)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)無法應用(yong)(yong)(yong)(yong)的(de)某些(xie)特(te)(te)殊管(guan)(guan)(guan)(guan)道(dao)(dao)上，如(ru)900彎管(guan)(guan)(guan)(guan)、三通(tong)管(guan)(guan)(guan)(guan)、悶(men)頭管(guan)(guan)(guan)(guan)等(deng)。d.防(fang)下(xia)垂加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)法，它用(yong)(yong)(yong)(yong)于(yu)特(te)(te)殊管(guan)(guan)(guan)(guan)道(dao)(dao)的(de)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)，如(ru)變經管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)和迂回(hui)管(guan)(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)固(gu)(gu)(gu)(gu)(gu)。

4、破損修補

如果(guo)是管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)外表面(mian)很輕(qing)(qing)微(wei)的(de)(de)破損(sun)，可(ke)(ke)以(yi)用(yong)專(zhuan)用(yong)的(de)(de)密(mi)封膠(jiao)(jiao)帶(dai)來進(jin)行(xing)(xing)修(xiu)(xiu)補即可(ke)(ke)。如果(guo)是管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)內表面(mian)有輕(qing)(qing)微(wei)破損(sun)，則可(ke)(ke)用(yong)舒伯專(zhuan)用(yong)修(xiu)(xiu)補膠(jiao)(jiao)進(jin)行(xing)(xing)修(xiu)(xiu)補。如果(guo)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)外表面(mian)的(de)(de)鋁箔層發生破損(sun)，而玻(bo)(bo)纖保溫層未(wei)發生損(sun)壞，則可(ke)(ke)選用(yong)一(yi)(yi)片合格(ge)的(de)(de)鋁箔片進(jin)行(xing)(xing)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)鋁箔表面(mian)的(de)(de)修(xiu)(xiu)補。如果(guo)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)壁的(de)(de)破損(sun)已達到玻(bo)(bo)纖保溫層時，則可(ke)(ke)將破損(sun)的(de)(de)地方切割下來，開出雌(ci)雄(xiong)搭(da)接口，另選一(yi)(yi)塊(kuai)完好的(de)(de)板材，根據(ju)(ju)切割下來的(de)(de)玻(bo)(bo)板尺寸切割好，留下雌(ci)雄(xiong)搭(da)接口，在四周接口上涂上修(xiu)(xiu)補膠(jiao)(jiao)及粘膠(jiao)(jiao)劑，根據(ju)(ju)工藝規范進(jin)行(xing)(xing)密(mi)封。如果(guo)管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)的(de)(de)破損(sun)比(bi)較(jiao)嚴重，且破損(sun)面(mian)積比(bi)較(jiao)大，有可(ke)(ke)能會影響通風管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)系(xi)統的(de)(de)正常運行(xing)(xing)時，就需要對管(guan)(guan)(guan)道(dao)(dao)(dao)(dao)(dao)進(jin)行(xing)(xing)更(geng)換修(xiu)(xiu)補，以(yi)保證系(xi)統的(de)(de)正常運行(xing)(xing)。
