    摘要: The present invention is a fly ash filler or filler blend having a particle size distribution with at least three modes that can be combined with a polymer or bitumen at higher filler loadings to produce a filled polymer or bitumen for composites that, in many cases, can produce improved mechanical properties for the composites over composites using conventional fillers. As a result, superior composites (e.g. those used in carpet backing) can be produced at a lower cost than conventional composites. The present invention also includes a method for producing a composite, comprising the steps of combining a polymer or bitumen with a fly ash filler or a filler blend having a particle size distribution with at least three modes to produce a filled polymer or bitumen and producing a composite with the resulting filled polymer or bitumen. The present invention further includes a method of determining what fly ashes can be used as fillers for composites.

    摘要: An elevated carpet system and method of applying the carpet system to a surface to protect the underlying surface from damaging exposure to water, salt and moisture. The carpet system includes a waterproofing membrane layer applied to the underlying surface and a weather-resistant carpet having a nibbed vinyl backing defined by an array of spaced nipple projections. The projections support the carpet in spaced relation above the waterproofing membrane layer so that an air gap is maintained therebetween to promote ventilation and drying of moisture which seeps through the carpet.

    摘要: A method of backing carpeting material 19 with hot-melt compositions such as atactic polypropylene (APP) or bitumen (with or without additives) comprises carefully doctoring selected thicknesses of the composition to the undersurface of the material 19 with the wear surface of the material uppermost. In one arrangement (FIG. 3) this is achieved using a lick roll arrangement 20 incorporating a doctor blade, cooling the backed product at cooling zones 28, 29 and applying the material to a nip formed by rollers 21. In another arrangement (FIG. 1) this is achieved by doctor box 16 applying the composition to a carrier 13, the carpeting material 19 then being laminated at roll 21 to the layer of composition, the laminate then being cooled before being stripped from the carrier (13). In a further arrangement (FIG. 2) the carrier is in the form of sheet material 15 which is supported by endless belt 13 and which is bonded into the hot-melt composition to become an integral part thereof.
