Abstract: The invention relates to a method of making a bonded man-made vitreous fibre product wherein the man-made vitreous fibres are bonded together by supplying a liquid binder composition through a conduit, passing the binder composition through a filter and then applying the binder composition to the fibres, whilst applying silane to the fibres separately from the binder composition. The binder is an aqueous composition which comprises - a component (i) in form of one or more oxidized lignins; - a component (ii) in form of one or more cross-linkers; - a component (iii) in form of one or more plasticizers.

Abstract: The invention relates to an apparatus for manufacturing mineral wool. The apparatus includes means (1) for producing molten mineral material, at least one fiberizing device (3) for forming fibres, into which fiberizing device the molten mineral material is fed (2) and by which fibres (12) are formed. The fiberizing device (3) comprises, rotationally arranged around a vertical axis (15), at least one fiberizing plate (13) having a vertical peripheral edge, into which are formed numerous small-sized holes (14), through which the molten material is led by centrifugal force to form fibres (12). Into the fiberizing device (3) are arranged elements to produce a vertical flow of blowing medium (16) to be led around the fiberizing plate (13), the flow causing the fibres (12) to turn downwards and, at the same time, to thin. Downstream the fiberizing device (3) is arranged a collection device (6), into which the formed fibres (12) are led and collected into a mat-like material. In connection with said at least one fiberizing plate (13) is arranged a substantially horizontal, relatively narrow channel (5), through which the fibres (12) are brought into the chamber space (7) of the collection device (6). The invention further relates to a method for manufacturing mineral wool and a mineral wool product manufactured by the method

Abstract: Collecting chamber comprising at least one adjustable wall and process for collecting of mineral wool solves technical problem of reducing shot in fiber production and/or reducing clumping of fiber by manipulating cross section and shape of entry zone (comprised of shot separation section (I) and/or adjustable section (II)). Such manipulation may serve two purposes: to reduce vortices and/or recirculation cells within collecting chamber, and to separate shot from fiber. There are many ways to achieve such manipulation. There can be apertures, moving walls, objects, membranes and other means for achieving said goal. Above referenced technical problem is also solved by a process comprised of following steps: - pouring mineral melt onto at least one spinner to discharge said mineral melt in form of droplets - blowing said droplets to elongate into fiber separating said fiber from shot formed by premature freezing of said drops by means of an adjustable wall (15, 12) in accordance with description above.
