METHOD OF MANUFACTURING GLASS FIBER MOLDING

PROBLEM TO BE SOLVED: To provide a method of manufacturing a glass fiber molding without dispersion of binder, without excessive inclusion of water and without heating up to a high temperature of about 480°C or more for fusing or drawing of glass fibers.SOLUTION: This invention relates to a method of manufacturing a glass fiber molding by holding glass wool between compression plates of a pressure molding machine. The glass wool held by the compression plates is compressed while hot air blown out of a plurality of hot air ejection holes arranged at the compression surfaces of the pair of oppositely facing compression plates of the pressure molding machine is passed through the glass wool, to attain the compression-molded glass fiber molding. The glass fiber molding is manufactured at a temperature of the hot air that is lower than a strain point of glass forming the glass wool by about 50 to 150°C. 【課題】バインダーを散布することなく、水を過剰に含ませることなく、又、ガラス繊維同士を融合または延伸させるために４８０℃程度以上の高温に加熱することなく、ガラス繊維成形体を製造する方法を提供する。【解決手段】ガラス繊維綿状体を加圧成形機の加圧盤に挟んで成形するガラス繊維成形体の製造方法であって、前記加圧成形機の対面する一対の加圧盤の加圧面に設けられた複数の熱風噴出孔より吹き出させた熱風をガラス繊維綿状体に通過させつつ、加圧盤で挟んだガラス繊維綿状体を加圧し、圧縮して成形されたガラス繊維成形体を得るものとし、前記熱風の温度が、前記ガラス繊維綿状体を形成するガラスの歪点より５０〜１５０℃低い温度でガラス繊維成形体を製造する。【選択図】図１
