<p>Gypsum fiberboard contains a boron compound for CO emission reduction. A novel gypsum fiberboard contains 0.1-0.6 wt.% boron compound. Independent claims are also included for the following: (i) gypsum fiberboard production by mixing gypsum, fibers, optional light aggregate and usual additives with water which contains 0.5-3 wt.% boron compound; and (ii) use of boron compounds, selected from boron oxide, boric acid and/or borates (especially alkali metal borates), for reducing CO emission from gypsum boards during a fire.</p> |
