A wet laid basemat for an acoustical ceiling tile comprising on a dry weight basis, 50% or more mineral wool fiber, including shot, less than 9% binder, and between 5 and 20% chopped strand glass fiber, and, optionally, minor amounts of other constituents, whereby the chopped strand glass fibers serve to promote and/or maintain voids in the mat such that the dry basemat has a density of between about 7-1/2 to about 10-1/2 lbs. per cubic foot and an NRC substantially greater than.55.
Abstract:
The invention is drawn to a glass fiber mesh fabric coated with an organic polymer coating having a reduced gross heat of combustion (less than 3.0 MJ/kg), said polymer coating comprising (i) from 60 wt% to 99.9 wt% of poly(vinylidene chloride) (PVDC) or a copolymer thereof; and (ii) from 0.1 wt% to 40 wt% of a formaldehyde-based resin selected from melamine-formaldehyde resins, phenol-formaldehyde resins, urea-formaldehyde resins or a combination thereof. The invention also provides a method for producing such a coated glass fiber mesh fabric.
Abstract:
In a glass wool compact production method comprising a) fiberizing glass raw materials to form glass wool (3), b) fluffing the glass wool to form a glass wool mat that has a unit weight equal to or greater than 2000 g/m2, c) press forming the glass wool mat to form a glass wool compact that has a thickness equal to or greater than 10 mm, before press forming, a water content ratio of the glass wool mat is controlled to be larger than 7.0 mass % and less than or equal to 30 mass % by applying water from nozzles (5) and them The press forming is done while keeping the temperature of the glass wool mat between 250 to 450°C.

Abstract:
Ein Glasfaservlies umfasst Glasfasern einer ersten Art, Glasfasern einer zweiten Art und ein Bindemittel. Dabei zeichnen sich die Glasfasern der ersten Art durch einen mittleren Faserdurchmesser von weniger als 6μπι sowie die Einhaltung des EC Protocol "ECB/TM/27 rev. 7" und die Glasfasern der zweiten Art durch einen mittleren Faserdurchmesser von mehr als 6µm aus. Das Verhältnis zwischen dem Gewichtsanteil der Glasfasern der ersten Art und dem Gewichtsanteil der Glasfasern der zweiten Art beträgt zwischen 0,01 und 0,15. Und das Flächengewicht des Glasfaservlieses beträgt zwischen 25g/m 2 und 80g/m 2 . Bei einem eine Nutzschicht und eine Strukturschicht aufweisenden CV-Bodenbelag umfasst die Strukturschicht ein derartiges, mit einer Imprägnierung versehenes Glasfaservlies.
Abstract:
The invention relates to a method for the continuous production of prepregs (11), whereby a fiber strand (2), consisting of fibers that are aligned at least in parallel, are whetted with a not yet hardened plastic matrix (14), and its upper side and lower side is covered with a cover material web (3, 4), and the plastic matrix-impregnated fiber strand (2) covered with the cover material web (3, 4) is cut as a prepreg (11) to a predetermined length or wound up to a coil. The aim of the invention is to make sure that the fibers arrive in a respective manufacturing installation in a desired orientation and are covered therein with the lower and upper cover material web (3, 4) in such a manner that a sufficient amount of the liquid plastic matrix can reach all fibers of the fiber strand (2), to reduce the percentage of fiber breakage to a minimum and to prevent the fibers form being folded crossways to the longitudinal extension of the fiber strand (2). For this purpose, the fiber strand (2) is brought together with the not yet hardened plastic matrix (14) and the two cover material webs (3, 4) on a convex and heated hot stage (6).
Abstract:
The invention relates to a textile reinforcement that comprises at least one glass-fiber cover layer and one voluminous, light-weight, thick and air-permeable nonwoven layer. The glass-fiber cover layer or the glass-fiber cover layers is/are interlinked with the nonwoven layer, and the glass-fiber cover layers are sewn or interknitted with the nonwoven layer by means of a sewing thread or exclusively or additionally by needle bonding.
Abstract:
Disclosed is a device for producing a glass wool sheet material, comprising a length-reducing cutting device (4) and a coiling device (6) following a hardening furnace (1) in the direction of movement of the sheet (7). As an option, the coiled roll can also be packaged in the coiling device (6). In order to obtain high production speeds with a predefined thickness of the sheet (7) even when thin materials are produced, the sheet (7) is separated into two or several layers (7a, 7b) by a cutting device (3) running through said sheet (7). Said layers (7a, 7b) are coiled jointly, optionally after being compressed in a compressing device (5).
