一、问题的提出传统的沥青膨胀珍珠岩保温材料几十年来一直被国内用在建筑上,但是近年来,它有被聚苯乙烯泡沫塑料板作保温材料取代的趋势,我们发现,现有沥青珍珠岩厂大量积压,而有好多地方还要上此类厂。有的部门在进行智力支边,也要上此类厂,这就需要从区域、经济、地理等方面进行综合论证,使国家利益不受到损害。这就是本文所要讨论的课题。二、传统屋面保温材料,沥青膨胀珍珠岩的特性多年来的施工,使用实践证明,沥青膨胀珍珠岩保温材料有以下弱点: (一)导热系数大(0.065～0.09瓦/米开尔文)保温性能较差,而且价格又偏高,增加了工程造价。
I. Problems raised Traditional asphalt-expanded perlite insulation materials have been used domestically for construction for decades, but in recent years it has been replaced by polystyrene foam panels as insulation materials. We have found that existing asphalt There is a large backlog of perlite plants, and there are many places where such plants are to be planted. Some departments in the implementation of intellectual support, but also on such plants, which requires a comprehensive demonstration from the regional, economic, geographical and other aspects, so that the national interests are not compromised. This is the subject of this article. Second, the traditional roof insulation materials, asphalt expanded perlite features over the years of construction, the use of practice has proved that the asphalt expanded perlite insulation material has the following weaknesses: (a) high thermal conductivity (0.065 ~ 0.09 watts / m Kelvin) insulation performance Poor, and the price is high, increasing the project cost.
