INCOMBUSTIBLE SOUND ABSORBING SHEET AND MEMBRANE CEILING USING THE SAME
PROBLEM TO BE SOLVED: To provide an incombustible sound absorbing sheet which has light-weight properties that are suitable for a membrane ceiling as an interior material for ceiling, is also excellent in sound absorbency, and is excellent in incombustible performance.SOLUTION: As a glass fiber base material having an arithmetic average of a vertical incident sound absorption coefficient of four sound ranges of 250 Hz, 500 Hz, 1,000 Hz and 2,000 Hz of 0.5 or more, has air permeability of a Frazier form method of 0.01 cm/cms or more and 25 cm/cms or less, a sheet, of which the total exothermic quantity for 20 minutes after irradiation with radiant heat of 50 kW/mhas been started is set at 8 MJ/mor less, is used for the membrane ceiling. In the glass fiber base material, (soft vinyl chloride resin) resin coating glass fiber yarns are used as warps or wefts, and intersection points of the warps and the wefts are thermally fused.SELECTED DRAWING: None
【課題】天井用内装材としての膜天井に好適な、軽量性を備え、かつ吸音性に優れ、さらには不燃性能に優れた不燃吸音シートの提供。【解決手段】250Hz、500Hz、1000Hz及び2000Hzの4音域の垂直入射吸音率の算術平均が0.5以上、且つフラジール形法通気性が0.01cm3/cm2・s以上、25cm3/cm2・sのガラス繊維基材として、50kW/m2の輻射熱を照射開始後20分間の総発熱量を8MJ/m2以下とするシートを膜天井に用いる。ガラス繊維基材は(軟質塩化ビニル樹脂)樹脂被覆ガラス繊維糸を経糸及び緯糸に用い、経糸と緯糸の交点を熱融着させる。【選択図】なし
