正是由于該材料材料具有以上的特性，因此應(yīng)用于中央空調(diào)風(fēng)管、冷熱輸送管道、潔凈廠房、冷庫(kù)、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(chǎng)主導(dǎo)地位的聚苯乙烯泡沫、聚氯乙烯泡沫、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(diǎn)是脆性大，開(kāi)孔率高，因此提高它的韌性是改善酚醛泡沫性能的關(guān)鍵技術(shù)。

該材料具有閉孔結(jié)構(gòu)，吸水性很小，耐低溫性好，耐溶凍性好，因此用于制冷設(shè)備和冷藏設(shè)備中，如冷凍機(jī)、冷風(fēng)管道、冷藏庫(kù)等。另外，由于聚苯乙烯泡沫塑料無(wú)毒、無(wú)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。上海管道美化管道保溫防腐防銹</p><div

<p> 早期的保溫材料 </p> <p> 多為天然礦物和自然資源原材料，如石棉、硅藻土、軟木、草繩、鋸末等。這些材料一般經(jīng)簡(jiǎn)單加工就可使用，其保溫結(jié)構(gòu)多為涂抹或填充形式。 </p> <p> 人工生產(chǎn)的保溫材料 </p> <p> 有玻璃棉、礦渣棉、珍珠巖、蛭石等。這些保溫材料一般為工廠生產(chǎn)的原料或預(yù)制半成品，其保溫結(jié)構(gòu)多為捆綁和砌筑形式。 </p> <p> 20世紀(jì)70年代以來(lái)研制開(kāi)發(fā)的保溫材料 </p> <p> 聚苯乙烯泡沫塑料、聚氨酯泡沫塑料、泡沫玻璃、泡沫石棉等，其保溫層的結(jié)構(gòu)多為噴涂或灌注成型的形式。 </p><p> 酚醛泡沫材料具有以下特性： </p> <p> 不燃性：酚醛泡沫材料是由阻燃樹(shù)脂和固化劑、不燃填料組成。無(wú)需加入任何阻燃填加劑，阻燃等級(jí)為難燃B1級(jí)。添加無(wú)機(jī)填料的高密度酚醛泡沫氧指數(shù)可達(dá)70。100 mm酚醛泡沫抗火焰能力可達(dá)1h以上而不被穿透。 </p> <p> 導(dǎo)熱系數(shù)：泡沫塑料的傳熱方式有氣相和聚合物相的熱傳導(dǎo)、氣相中的對(duì)流、泡孔壁的熱輻射三種。酚醛泡沫的導(dǎo)熱系數(shù)小，具有優(yōu)良的隔熱性能，導(dǎo)熱系數(shù)隨制品密度的增加而變大。 </p> <p> (3)抗腐蝕抗老化：酚醛泡沫材料已固化成型，長(zhǎng)期暴露在陽(yáng)光下，無(wú)明顯老化現(xiàn)象。使用壽命明顯長(zhǎng)于其它材料。除能被強(qiáng)堿腐蝕外，幾乎能耐所有的無(wú)機(jī)酸、有機(jī)酸及鹽類的腐蝕。 </p> <p> (4)吸聲性能：酚醛泡沫具有優(yōu)良的吸聲性能開(kāi)孔型的泡沫結(jié)構(gòu)更有利于吸聲。
