Title (EN) INSTALLATION FOR THE PRODUCTION OF MINERAL WOOL AND DEVICE FOR SPRAYING A SIZING COMPOSITION, FORMING PART OF SUCH AN INSTALLATION
(FR) INSTALLATION DE FABRICATION DE LAINE MINÉRALE ET DISPOSITIF DE PROJECTION D'UNE COMPOSITION D'ENCOLLAGE ÉQUIPANT UNE TELLE INSTALLATION
Abstract:
(EN) An annular device (20) for spraying a sizing composition onto mineral fibres (3) comprises at least one circuit (24, 26) for distributing the sizing composition and at least one spray nozzle (22) in fluid communication with the distribution circuit and arranged on the periphery of the annular spray device in order to spray the sizing composition onto the fibres that pass through the annular spray device defined by an axis of revolution (X-X). According to the invention, the sizing composition is a binder based on biosourced products, and at least one spray nozzle comprises a spray head (36) having a slot (50) through which the biosourced-product-based binder leaves the annular spray device, said slot having a rectangular cross-section such as to form a flat jet of biosourced-product-based binder.
(FR) Un dispositif annulaire de projection (20) d'une composition d'encollage sur des fibres minérales (3) comporte au moins un circuit de distribution (24, 26) de ladite composition d'encollage et au moins une buse de pulvérisation (22) communiquant fluidiquement avec le circuit de distribution et agencée sur le pourtour du dispositif annulaire de projection pour projeter la composition d'encollage sur les fibres destinées à passer à l'intérieur du dispositif annulaire de projection défini par un axe de révolution (X-X). Selon l'invention, la composition d'encollage est un liant à base de produits biosourcés et au moins une buse de pulvérisation comporte une tête de pulvérisation (36) présentant une fente (50), par laquelle le liant à base de produits biosourcés sort du dispositif annulaire de projection, à section rectangulaire de manière à former un jet plat de liant à base de produits biosourcés.
