Abstract:
A process for the manufacture of a fibre web containing a thermosetting resin, and a reinforced thermosetting resin composite containing the fibre web containing the thermosetting resin. The process comprises forming a fibre web (100) of at least reinforcing fibres (101), bringing at least a thermosetting resin (102) together with the reinforcing fibres, and joining the fibre web (100') at least partly by means of said thermosetting resin. Further, the process comprises having the thermosetting resin in the form of substantially dry grains (103), bringing said grains of thermosetting resin together with the reinforcing fibres (101) at a confluence temperature(T1) at about room temperature, and then joining the fibre web by prior to and/or under a pressure (p) at least partly heating the grains of thermosetting resin present in the fibre web (100') to a joining temperature (T2) being higher than the temperature (T1) at the confluence, and then cooling the fibre web (100") to room temperature. The reinforced thermosetting resin composite can preferably be used for sanitary products such as washing basins, toilet chairs, for different abrasive surfaces, for electricity conducting products and for medical technical products such as implantable devices for lengthening of a leg and the similar. Many other applications are considered as well.
Abstract:
the present invention provides a method for the production of bounded non-wovens carriers. The method includes providing a glass staple fiber containing non-woven which is pre-consolidated with a binder. The glass staple fiber non-woven is placed adjacent to one or more non-wovens of synthetic fibers and hydro-dynamically needling at a water beam pressure in the range of 100 to 400 bar.
Abstract:
A man-made vitreous fibre web is made by fiberising vitreous melt by a spinner (1), entraining the resultant fibres as a cloud of fibres in air, and collecting the fibres on a collector (31) that travels towards the spinner, generally in substantially closed chamber (8).
Abstract:
A compressed and packaged roll of bonded, low density, man-made vitreous fibre (MMVF) batt has upper and lower faces (30, 31) which extend in the X and Y axes, end edges (32) extending substantially along the X axis and side edges (33, 34) extending substantially along the Y axis. The batt is formed of a cured entangled stack of layers (7) each of which is formed of a continuous air laid MMVF web (7) including a bonding agent. The side edges of the layers are inclined to the faces and define the side edges (33, 34) of the batt, the end edges (32) of the batt are defined by end edges (35) of the layers and these end edges are substantially parallel to the faces (30, 31), other end edges (36) of the layers extend between the side edges across the faces at substantially regularly spaced apart positions, and the axis of the roll extends substantially along the X axis. The number of end edges (36) in each face (30, 31) is 0.4n or less, per metre, where n is the average number of layers in the Z axis. The batt may be made by cross lapping a web which is at least 2.5m, often 4 to 8m, wide.

Abstract:
A non-intumescent mat (20) for providing a support structure for low temperature fragile structures (18) in exhaust treatment devices (10), such as catalytic converters, diesel particulate traps, and like, including amorphous inorganic fibers. The fibers have Young's Modulus of less than about 20X10 psi and a geometric mean diameter of less than about 5 mu m. The mat (20) is adapted to provide a holding force of at least 5 psi throughout an average mat temperature range from ambient temperature up to at least about 350 DEG C. The amorphous inorganic fibers are preferably melt formed fibers including the fiberization product of a melt including alumina/silica.
Abstract:
Thermal insulation products are provided which comprise air-laid MMVF material having graphite substantially homogeneously distributed throughout. The product may be a granulated MMVF product but is preferably a product comprising a layer which is an air-laid MMVF batt or batt stratum having graphite distributed substantially homogeneously throughout. The inclusion of this graphite provides improvements in insulation properties ( lambda value).
Abstract:
The present invention relates to a process for the preparation of a mineral fibre board, and such a board having a dynamic elastic modulus which is substantially equal to the static elastic modulus in the order of magnitude. The process comprises provision of a primary web, compression of the primary web, doubling of the primary web under formation of a secondary web, curing of an added binder and optional compression of the secondary web.
Abstract:
The invention is directed to a method for producing a mineral wool product, which 5 comprises the step of contacting mineral fibres with a formaldehyde-free binder composition for mineral fibres.
Abstract:
Non-woven fiberglass veils, and laminates made therefrom, comprising: a plurality of glass fibers; a resin component; a fire-retardant component; and a particulate component, the particulate component comprising inorganic particles having a refractive index higher than a refractive index of the fire-retardant component and an average particle size of from about 0.1 to about 0.5 pm; wherein the fire-retardant component and the particulate component are present in a combined amount of from about 50% to about 90% by weight, based on the total weight of the veil, and wherein the fire-retardant component and the particulate component are present in a ratio by weight of from about 95:5 to about 50:50; are described.
