Publication number: 20120104306Abstract: Basalt filament is manufactured such that the fiber diameter can be controlled and the filament is not severed during winding. A network former and a glass modifier are formed and maintained with respect to basalt rock ore, and the crystallization and binding of basalt fiber are inhibited, the heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. The method includes: grinding basalt rock as a material; washing a resultant ground rock; melting the ground rock that has been washed; transforming a molten product into fiber; and drawing the fiber in an aligned manner, and winding it. The temperature of the molten product in the melting step is 1400 to 1650° C., and log ? is 2.15 to 2.35 dPa·s and preferably 2.2 to 2.3 dPa·s, where ? is the viscosity of the molten product.Type: ApplicationFiled: September 16, 2011Publication date: May 3, 2012Inventors: Sumio Kamiya, Hironori Sasaki, Noriaki Nakagawa

Patent number: 8042363Abstract: The invention relates to producing continuous organic fibers by stretching from molten minerals. These fibers can be used for producing heat resistant threads, rovings, cut fibers, fabrics, composite materials and products based thereon. The inventive glass has the following chemical composition in mass percentage: 15.9-18.1 Al2O3, 0.75-1.2 TiO2, 7.51-9.53 Fe2O3+FeO, 6.41-8.95 CaO, 2.5-6.4 MgO, 1.6-2.72 K2O, 3.3-4.1 Na2O, 0.23-0.5 P2O5, 0.02-0.15 SO3, 0.12-0.21 MnO, 0.05-0.19 BaO, impurities up to 1.0, the rest being SiO2. The inventive method consists in loading a ground composition in a melting furnace, in melting said composition, in homogenizing a melt, in consequently stabilizing the melt in the melting furnace feeder, in drawing and oiling the fiber and in winding it on a spool. Prior to loading, the composition is held in an alkali solution for 15-20 minutes, and is then washed with flowing water for 20-30 minutes and dried.Type: GrantFiled: December 25, 2006Date of Patent: October 25, 2011Inventors: Viktor F. Kibol, Sunao Nakanoo, Alexandr B. Biland, Roman V. Kibol

Patent number: 6620350Abstract: A method for making gradient refractive index optical components includes mixing a molten basic material (11) with a refractive index modifying material (21) in continuously changing proportions. The mixture is changed into a plurality of semi-molten fibers (41), and the fibers are rolled to form a continuous plate (51). The plate has a continuously changing refractive index along a lengthwise direction thereof. The plate is wound around a spindle (57) to obtain a wound preformed rod (58). The preformed rod is integrally fused by local heating, and drawn to form a draw (61) having a predetermined diameter. The draw is cut into pieces. Each piece can then be made into an optical component having a continuously changing refractive index in a radial direction. The method allows precise control of all steps, and such control is achieved with relative ease throughout.Type: GrantFiled: October 1, 2001Date of Patent: September 16, 2003Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Guangji Chen

Patent number: 6125660Abstract: The invention relates to a process for the manufacture of, in particular, continuous mineral fibers from rock, glass-containing technical wastes, technical glass wastes, and to an apparatus. The object of the invention is to create a process which enables the said group of starting materials to be processed from a stable melt to give, in particular, continuous fibers and thus to improve fiber quality and processability. The starting products are melted in a melting bath, transferred to a forehearth, a feeder device and then fed to a bushing device and from there taken off as thread, the melt being fed to the feeder device from a take-off area of the melt in which the melt has the parameters according to the invention of temperature, processing range, viscosity, quotient of viscosity and surface tension and energy of activation of viscous flow of the melt, and the ratio of height of the melt in the forehearth to the height of the melt in the melting bath being in a defined range.Type: GrantFiled: April 8, 1998Date of Patent: October 3, 2000Assignees: Gerhard Burger, Valentina GorobinskayaInventors: Valentina Gorobinskaya, Dirk Thamm, Irina Kravtchenko, Dalik Sojref, Alexander Medwedjew

Patent number: 6035667Abstract: When one strand, which is formed by gathering a multiplicity of glass filaments having a diameter of 9.mu. or less and formed by drawing molten glass flowed out through a multiplicity of orifices formed in the bottom portion of a bushing, is wound around a collet, the strand is wound to form a square-end cheese package by traversing the strand by a traversing device having a constant amplitude, while the strand is brought into contact with a rotative drum of a tension relaxing device to reduce the tension acting on the strand. Thus, the quality of a package of non-twisted glass yarn having a monofilament diameter of 3 to 9.mu. can be improved, a large quantity of the package can be formed, and the package can easily be transported.Type: GrantFiled: December 17, 1996Date of Patent: March 14, 2000Assignee: Nitto Glass Fiber Mfg.
