摘要： A method for the manufacture of very low density mineral wool structural panels on a moving foraminous support wire (40) by frothing a dilute aqueous dispersion of mineral wool. The froth, a mass of delicate, non-resilient and non-uniform bubbles among the entangled mineral wool fibers readily breaks, is stripped of water and dried without substantial loss of the highly open, porous structural configuration by a first controlled rate of maturation dewatering is rapidly stripped of remaining water and dried by passing high volumes of heated dry air through the structure with continued vacuum. The drainage water may be recycled in the process to maintain a low level of binder and any frothing aid additions.

摘要： Method for the manufacture of low density mineral wool structure panels by frothing a dilute aqueous dispersion of mineral wool, lightweight aggregate, binder and a small amount of amine-based cationic surfactant onto a non-woven scrim cover sheet (43). The resultant froth, a mass of very well formed, uniform bubbles, are of a nature that rapidly dewater and burst to concentrate the solids in the mass. The bubbles are readily broken without loss of the uniformly voided structural configuration by a first application of brief pulses of high vacuum followed by further dewatering under vaccum and rapid drying by passing high volumes of heated air through the voided mass without collapse of the structure to result in lightweight structural mineral wool panels.

摘要： Method for the manufacture of structural mineral panels on a foraminous support wire (40) forming a dilute aqueous dispersion of mineral fiber and/or lightweight aggregate with some fiber and binder solids in water. A small amount of cationic flocculant such as polyacrylamide is added sufficient to effect coating of the binder solids onto the mineral fiber materials and the slurry is passed to a first flooded section (42) of the support wire (40) to form an open, entangled, structural mass having water in interstitial spaces of the entangled mass. Water is stripped from the mass and the mass dried substantially without collapse of the open structure, first by application of brief pulses of high vacuum (44) followed by further vacuum (46) and passing heated dry air (49) through the open entangled structure. This produces a very uniform homogeneous panel core with very evenly spaced and uniformly sized voids in the open cored structure.

摘要： 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).
