摘要:
Glass-fiber composites are described that include a substrate containing glass fibers and particles in contact with the glass fiber substrate. The particles may include an alkali-metal containing compound. In addition, batteries are described with an anode, a cathode, and an electrolyte. The cathode may include alkali-metal containing nanoparticles in contact with glass fibers. Also describe are methods of making a glass-fiber composite. The methods may include the steps of forming a wet laid non-woven glass fiber substrate, and contacting alkali-metal containing particles on the substrate.

摘要:
Methods of making nonwoven mats having good strength after being scored and folded and particularly useful in making lightweight, compressible ceiling panels are disclosed. The mats also have excellent flame resistance. The mats include a blend comprising a major portion of glass fibers and a minor portion of man-made polymer fibers, the fibers being bound together with a cured binder containing a homopolymer or copolymer of polyacrylic acid and a polyol. The binder bonding the mat together can be cured to only a “B” stage to produce thermoformable mats or more fully cured to produce mats having the properties described above.
摘要:
A method of improving filtration efficiency of a fibrous nonwoven filter media comprises providing a filter media and incorporating in the filter media one or more additives selected from the group consisting of silicone additives, wax additives, and mixtures thereof. The filter media comprises glass fibers, polymer fibers, and optionally binder. Inclusion of silicone and/or wax additive(s) in a filter media has surprisingly been found to increase filtration efficiency, for example, by 10-15%.
摘要:
Wet laid, nonwoven, fibrous mats suitable for making MERV 6 or higher filters, and methods of making the nonwoven mats are disclosed. The mats include a blend comprising a major portion of glass fibers and a minor portion of man-made polymer fibers, such as polyester fibers, the fibers being bound together with a cured binder having a Tg in the range of about minus 30 to about 50 degrees C. The mats are pleated prior to assembling the filter in conventional manner. The only fibrous mat in the filters is wet laid fibrous nonwoven mat and the pleated filter media needs no other means of support in the filter frame.
摘要:
Making mats using glass fibers having a diameter of about 13+/−3 microns, bound with a binder formed from a homopolymer or a copolymer of polyacrylic acid and a polyol produces fibrous nonwoven mats having high tensile strength and also an unexpected high flame resistance considering the amount of oxygen in the binder. Mats of the present invention pass the National Fire Protection Association's (NFPA) Flammability Test. Tabor stiffness of these mats is greater than about 40, preferably greater than about 50 and most preferably greater than about 55. Air permeability of the mats is preferably within the range of about 500 to about 800 CFM/sq. ft. Methods of making the mat are also disclosed.
摘要:
Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.
摘要:
Embodiments of the invention provide fiber mat facers, ceiling panels, and method of manufacturing the same. A fiber mat facer may include a non-woven web of fibers having a first group of fibers with an average fiber diameter from about 6 μm to about 20 μm and a second group of fibers with an average fiber diameter from about 0.5 μm to about 5 μm. The fiber mat facer may also include a binder to bond together the non-woven web of fibers into the fiber mat. The binder may include a water repellant additive. The binder and/or fiber mat facer may further include an additive that enhances the opacity of the fiber mat facer. The fiber mat facer may also include a paint applied to an outer surface of the facer. The paint may include an additive that enhances the visual appeal of the facer and/or ceiling panel.

摘要:
Alkaline resistant fibrous products containing a binder comprised of a blend of urea formaldehyde and melamine formaldehyde and having particular use in bonding to alkaline materials having a pH of about 8 or above, including cementitious boards and other shapes, to provide manufacturing aids, reinforcement, fire resistance and a smooth surface are disclosed. Laminates containing one or more of the alkaline resistant fibrous products, with fibers bonded together with melamine formaldehyde and optionally a blend of urea formaldehyde and melamine formaldehyde binder, in contact with at least one cementitious layer are disclosed. Also, methods of making the alkaline resistant fibrous products and laminates that contain one or more layers of the alkaline resistant fibrous products are disclosed.
