LIGHTWEIGHT, HEAT INSULATING, HIGH MECHANICAL STRENGTH SHAPED PRODUCT AND METHOD OF PRODUCING THE SAME |
摘要 |
This invention relates to a process of a lightweight, heat insulating, high compressive strength, water insoluble material by heat treatment at temperatures between 650-950° C., possessing a low bulk density (from 300 to 800 kg/m<SUP>3</SUP>) and improved heat insulating capacity (lambda=0.07 to 0.25 W/m.deg.) when it has been used to form an article having a compressive strength of from 0.49 to 5.59 Mpa. The starting chemical composition comprising more than 90% by weight of either perlite, pumice or pumice related group of materials or mixture of them and an additive in quantities less than 10% by weight containing Na<SUB>2</SUB>O and B<SUB>2</SUB>O<SUB>3</SUB>. |
