FIRE-RESISTANT GLASS FIBERS, STRUCTURES EMPLOYING SUCH GLASS FIBERS ANS PROCESSES FOR FORMING SAME

摘要

Glass fiber septa (30) and insulation product (36) containing septa (30) between two glass wool layers (24) are treated, and thus rendered fire-resistant, by placing a phosphate-containing compound onto or in close proximity to the glass fibers. The phosphate-containing compound relases phosphoric acid when thermally degraded to form a protective silicate phosphate ceramic coating on the surface of the fibers. Exemplary phosphate-containing compounds are mono and diammonium phosphates, dicalcium phosphate, monocalcium phosphate, phosphoric acid, aluminum phosphate, and mixtures thereof.
