Title:
物体表面に断熱層を設ける方法
Document Type and Number:
Japanese Patent JP4773020
Kind Code:
B2
Abstract:
The invention concerns a method for producing an insulating layer (4, 28) on a surface (11, 27) of an object (1, 25), whereby a fibrous mineral material (16) and an aqueous binder (22) are applied on said surface (11, 27). The method consists in: providing opposite the surface (11) of the object a closed chamber (5; 26, 29) provided with at least an inlet (12) and at least an outlet for gas; blowing between the surface (11, 27) and the chamber (5; 26, 29) flakes of mineral wool carried by a gas stream (24) while directing on the flakes (16) at least a jet of aqueous binder (22) to form a layer (4, 28) defined by the chamber; drying the whole assembly (1, 7; 26, 27 29) to eliminate a substantial part of the water from the binder. The invention, used for objects of various shapes, enables to produce novel insulated objects, such as muffles (1) for cooking appliances or chimney pipes (25), with an insulating layer and covered with a perforated and/or porous sheet such as a glass fibre mat.
