通風管道斷面形狀的選擇

通(tong)(tong)(tong)風管(guan)道(dao)斷(duan)面(mian)的(de)形(xing)(xing)(xing)狀一(yi)般分(fen)矩(ju)(ju)形(xing)(xing)(xing)和圓(yuan)形(xing)(xing)(xing)2種(zhong)，在斷(duan)面(mian)積(ji)相同的(de)情況下，圓(yuan)形(xing)(xing)(xing)的(de)通(tong)(tong)(tong)風管(guan)道(dao)不(bu)僅(jin)阻力較(jiao)小，六合(he)區(qu)共板法蘭風管(guan)加工，強度大(da)，也節(jie)省(sheng)管(guan)材(cai)。對于(yu)圓(yuan)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)來說(shuo)(shuo)，直(zhi)徑越小越容易制造，而(er)且(qie)保溫也比(bi)(bi)較(jiao)方便。但矩(ju)(ju)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)的(de)管(guan)件制作比(bi)(bi)圓(yuan)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)的(de)制作要(yao)容易一(yi)些(xie)，且(qie)布置也比(bi)(bi)圓(yuan)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)要(yao)簡(jian)單。一(yi)般情況下，通(tong)(tong)(tong)風管(guan)道(dao)截面(mian)較(jiao)小而(er)管(guan)中流速較(jiao)高(gao)時(shi)，適合(he)采(cai)(cai)用(yong)圓(yuan)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)；通(tong)(tong)(tong)風管(guan)道(dao)截面(mian)較(jiao)大(da)時(shi)，宜(yi)采(cai)(cai)用(yong)矩(ju)(ju)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)，還可(ke)以充分(fen)利用(yong)建筑空間。對于(yu)矩(ju)(ju)形(xing)(xing)(xing)通(tong)(tong)(tong)風管(guan)道(dao)來說(shuo)(shuo)，寬與高(gao)的(de)比(bi)(bi)例越接(jie)近于(yu)1越好(hao)，不(bu)僅(jin)可(ke)以節(jie)省(sheng)運行(xing)的(de)動力，還可(ke)以節(jie)省(sheng)投資(zi)。

玻璃鋼板

主要研究結果如下：

(1)在通風工程中，常用的玻璃(li)管不是用玻璃(li)鋼(gang)做的，而是以板材或薄鋼(gang)板為模具手工制造(zao)的。

(2)在操作時，首先要(yao)在透明(ming)玻(bo)(bo)(bo)璃(li)紙的(de)模具面(mian)包層(ceng)(ceng)上涂上調(diao)整(zheng)過的(de)樹(shu)(shu)脂，然后再涂上一(yi)層(ceng)(ceng)玻(bo)(bo)(bo)璃(li)布(bu)，每一(yi)層(ceng)(ceng)樹(shu)(shu)脂涂上一(yi)層(ceng)(ceng)玻(bo)(bo)(bo)璃(li)布(bu)，布(bu)要(yao)錯開，而外層(ceng)(ceng)的(de)玻(bo)(bo)(bo)璃(li)布(bu)表面(mian)也要(yao)涂上一(yi)層(ceng)(ceng)薄的(de)樹(shu)(shu)脂。

(3)風(feng)管與法(fa)蘭(lan)一(yi)體(ti)化(hua)，共板法(fa)蘭(lan)風(feng)管加工安裝，法(fa)蘭(lan)應事先做(zuo)好，在涂布樹脂的過(guo)程中加入，與風(feng)管粘合在一(yi)起，固化(hua)一(yi)段(duan)時(shi)間后，整個風(feng)管即可脫出，達(da)到一(yi)定強度。

(4)玻璃(li)管及管件制造所用合成(cheng)樹(shu)(shu)脂應(ying)根據(ju)設(she)計要求(qiu)的(de)(de)耐(nai)酸、耐(nai)堿、自熄滅等(deng)性能選擇(ze)，合成(cheng)樹(shu)(shu)脂中填充(chong)物的(de)(de)含量應(ying)符合技術文件的(de)(de)要求(qiu)。

(5)玻璃(li)布的內容和(he)規(gui)格應(ying)符合設(she)計要求(qiu)，玻璃(li)布應(ying)保(bao)持干燥和(he)清潔，不得含(han)有蠟。玻璃(li)布的敷(fu)設(she)和(he)縫線應(ying)錯開，不應(ying)重疊。

(6)保(bao)溫玻璃管可使(shi)管壁形成層(ceng)間，夾層(ceng)材料可由巖棉、聚、聚氨酯泡沫、蜂窩紙等保(bao)溫材料制成，夾層(ceng)厚(hou)度和材料應根(gen)據工程需要進(jin)行選擇。

(7)玻璃纖維風管及配件的內表面應(ying)光滑光滑，表面平整(zheng)美觀，厚度(du)(du)應(ying)均勻，邊緣不毛刺，不應(ying)有(you)氣泡和分層，樹脂(zhi)固化(hua)度(du)(du)應(ying)達到90%以上。

(8)法蘭須(xu)與風管或配(pei)件整合(he)，并(bing)須(xu)與風管垂直，而(er)法蘭平面的(de)容許偏差不得大于2mm。
