Title:
ミネラルウールを形成するためのプロセス並びに装置
Document Type and Number:
Japanese Patent JP4455812
Kind Code:
B2
Abstract:
A method is provided to produce fine diameter glass fibers with fewer defects through a combination of lower attenuating gas velocities and the use of spinners having more and smaller holes. The method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral band perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position. The device includes at least two annular zones whose number of orifices per unit of surface area differs by a value greater than or equal to 5%, 10%, or 20%.
