正是由于該材料材料具有以上的特性，因此應用于中央空調(diào)風管，上海管道美化工程管道保溫生產(chǎn)廠家、冷熱輸送管道、潔凈廠房、冷庫、等需要使用防火、質(zhì)輕、保溫、隔音、潔凈、防潮材料的地方。與早期占市場主導地位的聚苯乙烯泡沫、聚氯乙烯泡沫，上海管道美化工程管道保溫生產(chǎn)廠家、聚氨酯泡沫等材料相比，在阻燃方面它具有特殊的優(yōu)良勝能。目前，酚醛泡沫已成為泡沫塑料中發(fā)展**快的品種之一。然而，酚醛泡沫比較大的弱點是脆性大，開孔率高，因此提高它的韌性是改善酚醛泡沫性能的關鍵技術。 </p> <p> 聚苯乙烯泡沫塑料保溫 </p> <p> 該材料具有閉孔結構，吸水性很小，耐低溫性好，耐溶凍性好，因此用于制冷設備和冷藏設備中，上海管道美化工程管道保溫生產(chǎn)廠家，如冷凍機、冷風管道、冷藏庫等。另外，由于聚苯乙烯泡沫塑料無毒、無腐蝕性、吸水性小、體輕、保溫、模具成型、抗酸堿腐蝕，可用于各種用途的管道保溫。上海管道美化工程管道保溫生產(chǎn)廠家</p><div

style="font-size:12px;">綁扎法綁扎法保溫采用預制保溫瓦或板塊料，用鍍鋅鋼絲綁扎在管道的壁面上，是熱力管道常用一種保溫方法。為使保溫材料與管壁緊密結合，保溫材料與管壁之間應涂抹一層石棉粉或石棉硅藻土膠泥（一般為3～5mm厚），然后再將保溫材料綁扎在管壁上。因礦渣棉、玻璃棉、巖棉等礦纖材料預制品抗水性能差，采用這些保溫材料時可不涂抹膠泥而直接綁扎。綁扎保溫材料時，應將橫向接縫錯開；如果保溫材料為管殼，應將縱向接縫設置在管道的兩側。采用雙層結構時，層表面必須平整，不平整時，礦纖維材料可用同類纖維狀材料填平，其他材料用膠泥抹平，層表面平整后方可進行下一層保溫。</span>

<p> 1、聚氨酯泡沫塑料保溫 </p> <p> 該材料用于直埋管段的保溫。在工程中的直埋保溫防腐管道，簡稱管中管，是指在鋼管外壁涂覆防腐層、保溫層與抗壓層的復合管材。它具有熱損失小，抗壓性能強，防腐防水性能好等特點，特別適合地下水位高的地區(qū)。它與傳統(tǒng)的地溝敷設管道相比，具有保溫性能好、防腐、絕緣性能好、使用壽命長、施工安裝簡便、占地面積小、工程造價低等一系列優(yōu)點，已經(jīng)用于集中供熱、輸油、化工、制冷及高寒地區(qū)供水等工程，本文不做詳細介紹。 </p> <p> <br /> </p> <p> <br /> </p><p> 質(zhì)量通病的防治 </p> <p> 保溫質(zhì)量通病主要表現(xiàn)為膠水涂刷不均勻，保溫材料粘接不嚴密，保溫材料的厚度選用不正確以及外觀型式不統(tǒng)一，型式不美觀等。在施工中有如下幾個主要質(zhì)量問題： </p> <p> 保溫層與木托粘接不嚴密。施工中，因工人保溫層長度測量不準確，工人施工時常將保溫材料拉長后粘接。由于材料本身有彈性，拉伸后即會收縮，時間長了，就出現(xiàn)了保溫材料與木托粘接處開膠的現(xiàn)象，這是保溫中常見的質(zhì)量問題之—。 </p> <p> 防治措施：在下料和粘接過程中不準拉伸材料，同時要求在木托兩側和保溫材料截面上都要涂刷膠水，膠水涂刷的要均勻飽滿；木托要選用規(guī)則的，如果木托斷裂成數(shù)塊，就要換掉，防止因冷橋產(chǎn)生結露現(xiàn)象。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

管道在保溫之前要進行水管壓力試驗，在水壓試驗合格后進行試壓與保溫工作的工序交接，以防止將未進行試壓的水管保溫 </p> <p> <br /> </p> <p> 材料的選用 </p> <p> 系統(tǒng)內(nèi)介質(zhì)溫度與環(huán)境溫度差越大，選用厚度就越大；冷系統(tǒng)所在環(huán)境相對濕度越大，選用厚度就越大；冷媒介質(zhì)管徑小150mm時，管徑越大，選用厚度就越大；工程系統(tǒng)的空氣愈不流通，選用厚度就越大。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br />
