    • A granular fibre-free microporous thermal insulation material, having a thermal conductivity less than 0.05 W/mK and a shrinkage of not more than 10%, which is free flowing and consists of granules of an intimate mixture of: 30-95% dry weight microporous insulating material; 5-70% dry weight infrared opacifier material; 0-50% particulate insulating filler material; and 0-5% binder material. The material is made by mixing together the microporous insulating material and the infrared opacifier material to form an intimate aerated mixture with a first density; conveying the intimate mixture at a first volumetric flow rate to an extrusion means (5); extruding the intimate mixture as a compressed material with a second density greater than the first density at a second volumetric flow rate lower than the first volumetric flow rate; venting a proportion of air from the aerated intimate mixture through a porous membrane to relieve pressure generated within the intimate mixture due to the change from the first volumetric flow rate to the second volumetric flow rate; and granulating the compressed material.
    • 一种粒状无纤维微孔保温材料,其热导率小于0.05W / mK,收缩率不大于10%,其自由流动,并由30-95%干重的紧密混合物颗粒组成 微孔绝缘材料; 5-70%干重红外曝光材料; 0-50%颗粒绝缘填料; 和0-5%的粘合剂材料。 该材料通过将微孔绝缘材料和红外遮光材料混合在一起以形成具有第一密度的紧密充气混合物; 将第一体积流量的密实混合物输送到挤出装置(5); 以比第一体积流速低的第二体积流速将紧密混合物挤压成具有大于第一密度的第二密度的压缩材料; 通过多孔膜从充气的紧密混合物排出一定比例的空气,以释放由于从第一体积流速向第二体积流速的变化而在紧密混合物内产生的压力; 并对压缩物进行造粒。
