    摘要: 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.

    摘要: The invention is an improved method for manufacturing fiberglass. In the method of the invention, quartz is replaced in whole or in part by silica containing raw materials. The use of silica containing raw materials as a replacement for quartz results in significant energy savings and a reduction in defect producing components in the glass.

    摘要: The present invention furnishes a method for producing mineral wool wherein a molten mineral material is fed into a spinner (1) the peripheral wall (2) of which comprises a multiplicity of orifices with small diameters wherethrough the mineral molten material is centrifuged to form filaments which are subjected to a supplementary attenuating effect of a gas flow flowing along and heating the peripheral wall (2) of the spinner (1) and generated by a concentric annular burner (8) arranged concentrically to the spinner (1), and wherein the exit area of the burner (8) is subdivided into an annular radially inner hot zone and an annular radially outer cooling zone of substantially lower temperature; the invention moreover concerns an apparatus for implementing the method.

    摘要: A fiber glass air filtration media comprises a blanket of glass fibers with about 25% to 35% by weight of the glass fibers being fine glass fibers having an average diameter of less than 3.5 microns and about 65% to 75% by weight of the glass fibers being coarse glass fibers having an average diameter of more than 3.5 microns. The fine and coarse glass fibers are randomly intermingled throughout the blanket. The blanket is formed by producing the fine glass fibers on a first set of fiber generators and the coarse glass fibers on a second set of fiber generators. The fiber generators are laterally aligned across the width of and direct gaseous streams of the glass fibers at a moving collection surface where the blanket is formed. The fiber generators of the first set alternate with the fiber generators of the second set and the glass fibers produced by the two sets of fiber generators are mixed together before being deposited on the collection surface.

    摘要: The objective is to provide a process and an apparatus for the continuous production of mineral wool nonwovens, by means of which a stable flow pattern is created in the chute, thus facilitating a clearly defined, homogeneous layer of deposited mineral wool.According to the invention, at least one backflow region (24, 25) is generated in the chute (9) outside the fibre flow (23), which backflow region (24, 25) is sufficient for such a large-volume backflow with such a low mean velocity that appreciable upward fibre transport is avoided. In this connection, a portion (32) of the process air entrained with the fibre flow is deflected upward in the backflow, and another portion (34) of the process air is extracted.
