    摘要: In making entangled fibrous products by depositing fibers from streams of hot gas in which they are entrained, dust suppressant incorporated in the product by introducing at least a portion of it into the cooler region surrounding and separating the fiber-entraining streams of hot gas and communicating with the zone wherein the fibers are deposited minimizes smoke evolution as compared to introducing such portion into the hot gas streams.

    摘要: A method of repairing a paved surface utilizes a nonwoven or woven fibrous mat made from fibers including polymer fibers, the polymer fibers having a melting point greater than about 320° F. (160° C.). The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another mat comprises a nonwoven or woven fibrous mat made from fibers selected from the group consisting of mineral fibers, polymer fibers, natural fibers, and mixtures thereof, and a rubbery binder. Another mat comprises a nonwoven or woven fibrous mat made from a blend of high melt polymer fibers having a melting point of at least 350° F. (177° C.) and low melt polymer fibers having a melting point of less than 350° F. (177° C.).

    摘要: A penetration pocket, useful to seal roof openings at protruding pipes or the like, is made of a material compatible with roofing asphalt. The penetration pocket material is asphalt-based with polymeric materials added to impart strength and toughness. Fibrous material may also be added for increased strength. The roofing asphalt, when applied around the penetration pocket, fuses with penetration pocket walls and base, and upon cooling, the penetration pocket and the roofing asphalt are welded together to effect a secure, water-proof joint.

    摘要: A method of producing a roofing shingle coating asphalt from a non-coating grade asphalt feedstock includes the following steps. The non-coating grade asphalt feedstock is partially blown to lower its penetration to a first penetration that is within or close to a target penetration range of the coating asphalt, and to raise its softening point to a first softening point that is lower than a target softening point range of the coating asphalt. A wax is added to the partially blown non-coating grade asphalt to further raise its softening point to a second softening point that is within the target softening point range to produce the coating asphalt. The wax may also be added during the blowing process. Resulting roofing coating asphalt compositions may comprise a paving grade asphalt and a wax, and yet still has desirable penetration, softening point and viscosity.
