Abstract
PURPOSE: To obtain a light, highly flexible formed body without generating dust by spray forming special bubbly slurry prepared by adding water, a surface active agent and a thickener to a compound of inorganic fiber and hydraulic inorganic binder.
CONSTITUTION: Inorganic fiber such as rock wool and hydraulic inorganic binder such as portland cement are compounded in a range of 70:30W35:65 in weight ratio and 150W300% of water is added to it. Further, 1W5% of surface active agent as a foaming agent and 0.2W1.0% of thickener as both foam stabilizer and water holding agent are added and mixed to prepare slurry containing minute strong bubbles 40W80% in quantity of air. This bubbly slurry is carried in a duct and sprayed with compressed air from a nozzle, and bubbles in the slurry are retained after spraying. By this method, formed products suitable for fireproofing, heat insulation, sound absorption etc. and having bulk specific gravity of ≤0.4 can be obtained freely.
