    摘要： A hollow, porous, silica-rich fiber, a process for producing same, and a process for enriching at least one gas from a gaseous mixture utilizing at least one fiber to result in gas separations with good permeability and good selectivity. The fiber is non-crystalline and has pore sizes having a range of 1 to around 50 Angstroms in diameter and a mean pore size of around less than 20 Angstroms in diameter and a filament diameter in the range of 1 to around 250 microns and a wall thickness in the range of around 1 to 50 microns. The fibers with a fine pore structure and thin walls are produced by forming hollow glass fibers hindered or fully phase-separable boron and/or alkali metal glass composition, by attenuation from melt at speeds in the range of 500 ft/min to around 30,000 ft/min. The phase-separable glass fibers are heat treated to yield limited phase-separated hollow glass fibers and these fibers are leached to extract acid and/or water soluble components. For fully phase-separable, hollow glass fibers, a limited heat treatment is used before leaching, where the heat treatment is at a temperature of around 300 to less than 480.degree. C. for a time of around 5 minutes to 24 hours. The hindered, phase-separable, hollow glass fibers are heat treated at a temperature in the range of about 400 to about 600.degree. C. At least one hollow, porous, silica-rich fiber is used in a device suitable to contain a gaseous mixture and the permeate is withdrawn from the silica-rich fiber at the opposite side from that at which the gaseous mixture contacts the hollow, porous fiber.

    摘要： Porous, silica-rich shapes have improved strength and abrasion resistance by leaching the precursor glass shape in preconditioned acid having silica ion and at least one common ion that is also present in the precursor glass shape. The precursor glass shapes have shapes such as fibers, hollow fibers, tubes, rods, beads, hollow spheres and plates and compositions having 30-75 volume percent silica and at least 10-65 volume percent nonsiliceous acid extractable components. Preconditioning of the acid solution results from a pretreatment of the acid with compounds that dissociate into the ions when added to the acid solution or with shapes, particles or fragments of glass compositions different from or similar to the glass shape to be leached so long as the glass composition has extractable material to provide the silica ion and at least one common ion.

    摘要： The present invention provides non-heat cleaned glass fiber fabrics comprising resin compatible coatings that offer higher tensile strengths than corresponding fabrics that have been heat cleaned and silane finished. These fabrics can be used in a wide variety of applications, such as reinforcements for composites such as printed circuit boards. In one nonlimiting embodiment, the invention provides a non-heat cleaned fabric comprising a plurality of fiber strands in a warp direction and a fill direction, each fiber strand comprising a plurality of E-glass fiber, and having a resin compatible coating composition on at least a portion of a surface of at least one fiber strand, wherein the fabric has a tensile strength of at least 267 Newtons when measured in the warp direction or fill direction. Although not required, the fabric also has a tensile strength of at least 1.5 times that of a corresponding fabric that is heat cleaned by heating the corresponding fabric to a temperature of at least 380° C. for at least 60 hours and silane finished when measured in the warp direction or fill direction.
