    • A process is described for the preparation of perlite ore fines for expansion. The ore fines are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines. Suitable agglomerating agents mentioned are the boron acids, particularly orthoboric acid and metaboric acid. The perlite ore fines and agglomerating agent are mixed, preferably by dry mixing, and then heated to the temperature of the viscous liquid phase and held at that temperature for a short period while the liquid coats at least a portion of the perlite ore fines and effects agglomeration. Thereafter, the agglomerated perlite ore fines can be expanded in a conventional perlite ore expander. The resulting expanded materials have properties essentially identical to standard expanded perlite ore and are useful for such purposes as insulating fillers and light weight aggregates.
    • 描述了用于制备用于膨胀的珍珠岩矿石细粉的方法。 矿石粉末用聚集剂处理,该凝聚剂在高于环境温度但低于珍珠岩矿粉细菌的临界脱水温度的温度下具有粘稠液相。 所提及的合适的附聚剂是硼酸,特别是原硼酸和偏硼酸。 将珍珠岩矿粉和凝聚剂混合,优选通过干混合,然后加热至粘稠液相的温度并在该温度下保持短时间,同时液体涂覆至少一部分珍珠岩矿石细粉和效果 凝聚。 此后,聚集的珍珠岩矿粉可以在常规的珍珠岩矿石膨胀机中膨胀。 所得到的膨胀材料具有与标准膨胀珍珠岩矿石基本相同的性质,并且可用于绝缘填料和轻质聚集体的目的。

    • An economical and versatile fibrous glass mat displaying improved resistance to wetting or strike-through by various curable materials when said materials are placed on one surface of said mat while in liquid state is disclosed. This mat, which is especially suited as a carrier, substrate or facer for such curable substances, comprises a blend of fibers. This blend of fibers includes a majority of base fibers having a mean diameter in the range of ten (10) microns with a minor amount of microfibers. The binder formulation, which when cured holds the blend of fibers together to form a self-supporting mat, includes conventional binder resins with a minor amount of wet proofing resinous materials.Preferably, the resulting mat has a porosity of no greater than two-hundred and twenty-five (225) cubic feet per minute per square foot of mat in accordance with the Frazier Air Permeability Test. Also, claimed is a laminate comprising this novel mat and a vinyl plastisol coating or a coating of a foam insulation material such as a polyurethane or polyisocyanurate foam.
    • 一种经济且通用的纤维玻璃垫,当所述材料在液体状态下放置在所述垫的一个表面上时,其表现出改进的耐各种可固化材料的润湿或渗透性。 该垫特别适用于这种可固化物质的载体,底物或面,包括纤维的混合物。 这种纤维混合物包括平均直径在十(10)微米范围内的少数基本纤维的大多数,并具有少量的微纤维。 粘合剂制剂在固化时将纤维的共混物保持在一起以形成自支撑垫,包括具有少量防湿树脂材料的常规粘合剂树脂。 优选地,根据Frazier空气渗透性试验,得到的垫具有不大于每平方英尺垫的二百二十五(225)立方英尺每分钟的孔隙率。 此外,要求保护的是包含这种新型垫和乙烯基增塑溶胶涂层或泡沫绝缘材料如聚氨酯或聚异氰脲酸酯泡沫的涂层的层压材料。
