對(duì)彎頭保溫時(shí)，盡量采用直接彎管保溫，即保溫層粘接縫順著管道方向，而不采用切割馬蹄型分多次粘接來找補(bǔ)弧度的方法。這樣可省去大量的人力時(shí)間和材料，還能保證保溫質(zhì)量，同時(shí)外觀上也較后者美觀。 </p> <p> 穿墻套管歪斜。實(shí)際施工容易出現(xiàn)管道穿墻處的套管放置偏心或偏出墻體，致使保溫層不能穿過墻體，起不到保溫的作用。 </p> <p> 防治措施：套管一般是直接采用施工中的管道切割制作，根據(jù)墻體厚度和抹灰厚度定出套管長度，在墻體施工前用多根楔型木條把套管支撐起來，固定在管道上，塞木條時(shí)要保證套管與管道同心。保溫施工時(shí)把木條拆下來，再將保溫層穿過套管。上海管道保溫外護(hù)管道保溫生產(chǎn)廠家</p><div style="width:100%;text-align:

纏包法保溫纏包法保溫采用卷狀的軟質(zhì)保溫材料（如各種棉等）。施工時(shí)需要將成卷的材料根據(jù)管徑的大小剪裁成適當(dāng)寬度（200～300mm）的條帶，以螺旋狀纏包到管道；也可以根據(jù)管道的圓周長度進(jìn)行剪裁，以原幅寬對(duì)縫平包到管道上。不管采用哪種方法，均需邊纏、邊壓、邊抽緊，使保溫后的密度達(dá)到設(shè)計(jì)要求。一般礦渣棉氈纏包后的密度不應(yīng)小于150～200kg/m3，玻璃棉氈纏包后的密度不應(yīng)小于100～130kg/m3，超細(xì)玻璃棉氈纏包后的密度不應(yīng)小于40～60kg/m3。如果棉氈的厚度達(dá)不到規(guī)定的要求，可采用兩層或多層纏包。纏包時(shí)接縫應(yīng)緊密結(jié)合，如有縫隙，應(yīng)用同等材料填塞。采用分層纏包時(shí)，第二層應(yīng)仔細(xì)壓縫。

目前似乎還沒有非常理想的適用于暖通空調(diào)及制冷系統(tǒng)的保溫材料。比如常用的：橡塑材料其導(dǎo)熱系數(shù)小、抗蒸汽滲透性好，便于施工，但還不是不燃材料，如作為高溫?zé)崴鼙乜赡軙?huì)有變形，價(jià)格也稍貴。而離心玻璃棉，屬于不燃材料，導(dǎo)熱系數(shù)小，但抗蒸汽滲透性差，如作為冷凍水管道保溫，要特別處理好**的防潮隔汽層，既要密閉又要具有一定強(qiáng)度 (傳統(tǒng)的鋁箔容易被劃破損壞)。所以保溫材料的基本規(guī)律是：凡不燃材料幾乎都不抗蒸汽滲透；而抗蒸汽滲透材料幾乎都可燃甚至?xí)a(chǎn)生窒息煙氣。但是無論如何，只要我們把握好各種保溫材料的適用條件，清楚其施工時(shí)注意事項(xiàng)，掌握施工要點(diǎn)，就能夠做好各種保溫工作。 </p> <p>

保溫材料之間粘接不嚴(yán)密。保溫材料之間的粘接比較常見，特別是在水平管上方和立管的側(cè)面保溫材料的粘接縫較長，很容易出現(xiàn)粘接不牢的現(xiàn)象。這主要是材料在切割過程中截面不平整、膠水涂刷不均勻造成的，這也是保溫中常見的質(zhì)量問題之一。 </p> <p> 防治措施：要求施工人員在下料的過程中要使用直尺，不能徒手下料，涂刷膠水時(shí)要求均勻，粘接時(shí)要從一側(cè)開始逐步向另一側(cè)用力擠壓，保證材料的切割面都能受力粘接牢固。 </p> <p> 彎頭處開膠。管道保溫時(shí)一般要求把保溫層接縫放在管道上方，而在管道的彎頭上方經(jīng)常出現(xiàn)保溫層開裂現(xiàn)象，致使局部保溫層過薄，造成凝結(jié)水結(jié)露。上海管道保溫外護(hù)管道保溫生產(chǎn)廠家</p><p
