    • Glass fiber insulation products, and methods of manufacturing small diameter glass fibers with fewer stress-rising defects are provided. The insulation products of this invention can provide the same thermal resistance or R-value with reductions in fiber density of at least about 20% or more while achieving acceptable recovery of the nominal thickness following compression. The methods provided by this invention can 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. A preferred method of the invention uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral bland perforated with orifices distributed in a plurality of annular zones (ZA) arranged on top of each other, assuming that the centrifufe is in centrifugation position. In accordance with the invention, the device also includes at least two annualr zones (ZA1, ZA2) whose number or orifices per unit of surface area (NS1, NS2) differs by a value greater than or equal to 5%, in particular greater than or equal to 10%, and even 20%.
    • 提供玻璃纤维绝缘产品,以及制造具有较少应力上升缺陷的小直径玻璃纤维的方法。 本发明的绝缘产品可以提供相同的热阻或R值,纤维密度降低至少约20%或更多,同时在压缩后实现可接受的标称厚度恢复。 本发明提供的方法可以通过组合较低的衰减气体速度和使用具有越来越小的孔的旋转器来生产具有较少缺陷的细直径玻璃纤维。 本发明的优选方法使用一种用于矿物纤维的内部离心的装置,包括装备有外围平坦的离心机的离心机,该离心机布置有分布在彼此顶部的多个环形区域(ZA)中的孔口,假定离心机处于离心状态 位置。 根据本发明,该装置还包括至少两个每单位表面积(NS1,NS2)的数量或孔数大于或等于5%的年度区域(ZA1,ZA2),特别是大于 或等于10%,甚至20%。
