聚氨酯發(fā)泡保溫材料聚氨酯硬質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)管局質量抽查不合格產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)管局對電熱毯、室內加熱器等28種產品組織開展了質量監(jiān)督抽查。監(jiān)督抽查通報顯示，有34家企業(yè)生產的34批次產品不合格。據(jù)了解，本次共監(jiān)督抽查1061家企業(yè)生產的1273批次產品，包括電熱毯、室內加熱器、燃氣器具類產品、LED燈產品、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構特點玻璃棉保溫管安裝注意事項玻璃棉保溫管，相信大家對這五個字都很陌生。玻璃棉保溫管在我們的日常生活中確實是比較少見，但在工業(yè)上卻應用。雖然生活中我們很少需要用到玻璃棉保溫管。阿克蘇內外涂塑防腐保溫管哪家好昌吉黑夾殼保溫管行價；</p><div
