聚氨酯發(fā)泡保溫材料聚氨酯硬質(zhì)泡沫塑料自三十年代聚氨酯合成料誕生以來，一直作為一種優(yōu)良的絕熱保溫材料而得到長足的發(fā)展，其應(yīng)用范圍也是越來越，更由于其施工簡便，節(jié)能防腐效果而被大量地用于各種供熱，制冷、輸油、輸氣等各種管道。防水、防腐、耐老化：由于聚氨酯泡沫的閉孔率可達(dá)到92%以上，因此，用聚氨酯泡沫作為直埋管道的保溫層，不僅可以起到保溫隔熱的作用，而且能有效地防止水、濕氣以及其它遼寧省市場監(jiān)管局質(zhì)量抽查不合格產(chǎn)品有這五家防水企業(yè)慧聰防水網(wǎng)訊：11月23日，記者從遼寧省市場監(jiān)督管理局獲悉，近期，遼寧省市場監(jiān)管局對(duì)電熱毯、室內(nèi)加熱器等28種產(chǎn)品組織開展了質(zhì)量監(jiān)督抽查。監(jiān)督抽查通報(bào)顯示，有34家企業(yè)生產(chǎn)的34批次產(chǎn)品不合格。據(jù)了解，本次共監(jiān)督抽查1061家企業(yè)生產(chǎn)的1273批次產(chǎn)品，包括電熱毯、室內(nèi)加熱器、燃?xì)馄骶哳惍a(chǎn)品、LED燈產(chǎn)品、服裝、定配眼鏡、閥門水嘴、水泥、混凝土外加劑、直埋保溫管、建筑防水卷材、工業(yè)泵、橡膠密封制品玻璃棉保溫管結(jié)構(gòu)特點(diǎn)玻璃棉保溫管安裝注意事項(xiàng)玻璃棉保溫管，相信大家對(duì)這五個(gè)字都很陌生。玻璃棉保溫管在我們的日常生活中確實(shí)是比較少見，但在工業(yè)上卻應(yīng)用。雖然生活中我們很少需要用到玻璃棉保溫管。</p><p>
