Abstract:
A composition for acrylic artificial marble according to the present invention comprises (a) an acrylic resin polymer; (b) metal-deposited polyester film particles; and (c) an inorganic filler. The composition of the present invention may have excellent diffused reflection by using the polyester film particles having plural deposited metal layers, so that the artificial marble may have novel pattern.
Abstract:
A lightweight structural concrete with screw-ability and nail-ability similar to wood-is composed of a non-structural and ultra lightweight aggregate such as expanded perlite or a combination of expanded perlite and polystyrene beads of a particular size distribution and volume amount, entrained air cells of another specific size distribution and volume amount, and dense cementitious composition of a cement binder, a fine grade structural filler no larger than concrete sand grade, a pozzolan, and optional micro-fibers for reinforcement. This structural concrete matrix is optimized to hold 13 gauge T-nails and bugle head wood screws with thread ranging from 8 to 11 threads per inch and diameter of 0.10" to 0.137". The resulting concrete will have consistent screw-ability and nail-ability similar to that of wood.
Abstract:
The invention concerns a soft sealing material, in the form of paper, cardboard or sheets, which is free of asbestos and other inorganic fibres, the sealing material consisting of reinforcement and sheet-forming fibres, fillers to increase the friction between the graphite flakes, plus organic binders, a mixture of non-fibrillated organic fibres with an extension at break (at up to 200 DEG C) of
Abstract:
Non-fractured, non-fibrillatable short fibers, for reinforcing matrix materials such as concrete, have substantially uniform transverse cross-sectional areas along their length for maximum efficiency in pull-out resistance, and two different tapering characteristics along their lengths. Preferred bi-tapered fibers of the invention have a high modulus of elasticity in the range of 5-250 Gigapascal and are preferably modulated in both tapering dimensions. Matrix materials containing the fibers, as well as a method for making the fibers, are disclosed.
Abstract:
This invention relates to a reinforcement structure which is used in providing cementitious mixtures supplemental support and strength upon setting, and more particularly, to a reinforcement structure which comprises a plurality of oriented reinforcing fibrous and/or filamentary components having a finite cut length, and fastening the reinforcing fibrous and/or filamentary components by one or more circumferential retaining elements.
Abstract:
A fiber-reinforced composite material with inorganic binder such as Portland cement. Fiber reinforcement is continuous fibrous structure, typically a flat woven web of flat fibrillated tow bands of polypropylene prepared by stretching a polypropylene film in a ratio of at least 1:15 and fibrillating by means of a rotating needle or cutter roller to obtain fibrous elements of from about 2 to about 35 dtex.
Abstract:
A wellbore treatment fluid comprising: a base fluid; and an additive comprising: a first polymer bundle selected from the group consisting of cellulose nanofibrils, cellulose nanocrystals, and combinations thereof; and a second polymer, wherein the second polymer attaches to the first polymer bundle by a non-covalent mechanism. A method of treating a portion of a wellbore comprising: introducing the treatment fluid into the wellbore.

Abstract:
The present invention relates to thermoplastic and polyareneazole pulp for use as reinforcement material in products including for example fluid sealing materials, as a processing aid including its use as a thixotrope, and as a filter material. The pulp comprises (a) irregularly shaped, thermoplastic fiber fibrous structures, (b) irregularly shaped, polyareneazole fibrous structures and (c) water, whereby thermoplastic fiber fibrils and/or stalks are substantially entangled with polyareneazole fibrils and/or stalks. The invention further relates to processes for making such thermoplastic and polyareneazole pulp.
Abstract:
The present invention relates to a filamentary film construct which is used in providing cementitious mixtures supplemental and reinforcing strength upon setting, and more particularly, to a unitized filamentary construct which comprises a plurality of oriented reinforcing filamentary film components combined with a circumferential retaining element, said circumferential retaining element providing temporary retention of the oriented reinforcing filamentary components until such point the unitized filamentary substrate is incorporated and subjected to mechanical agitation during preparation of a cementitious blend or mixture. The unitized filamentary film construct is endowed with inherent and improved dispensability and dispersability of the associated reinforcing filamentary component into organic or inorganic cementitious matrixes, such as concrete, mortar, plaster, etc. The oriented reinforcing filamentary film components can comprise fibrillated film components.
