Abstract (en)
[origin: WO8805096A1] A method for the manufacture of very low density mineral wool structural panels on a moving foraminous support wire (40). A dilute aqueous furnish of mineral wool, lightweight aggregate, cooked wheat starch, cationic guar gum and non-ionic surfactant is formed, mixed to form a small amount of delicate non-resilient bubbles and ionically couple the mineral surfaces to the starch and gum, and deposited upon the wire (40) to form an open, porous entangled mass which is rapidly stripped of water and dried in a flow-through configuration (49).
