Abstract

A fluorocarbon-free filtration media includes a fluorocarbon-free additive and mimics one or more properties of traditional fluorocarbon-containing filtration media. A method of making the fluorocarbon-free filtration media includes forming a nonwoven web of microglass fibers and applying the fluorocarbon-free additive. The fluorocarbon-free additive can be added before incorporating a binder, with the binder, or both before and with the binder.

Abstract

A method of agglomerating bulk ceramic fibers includes mixing the bulk ceramic fibers with water to form wet fibers; mixing the wet fibers with a binder including an organic binder and/or an inorganic binder to form agglomerates; and drying the agglomerates. The agglomerates may be mixed with additional binders and fillers to form an insulating mix that may be used to insulate a furnace or other heat source. A foaming nozzle may be used for the application of agglomerates. A foaming agent and water are air atomized within the foaming nozzle and the resulting foam is mixed into pneumatically conveyed agglomerates, which result results in a lightweight refractory material layer on a target substrate.

Abstract

A method of agglomerating bulk ceramic fibers includes mixing the bulk ceramic fibers with water to form wet fibers; mixing the wet fibers with a binder including an organic binder and/or an inorganic binder to form agglomerates; and drying the agglomerates. The agglomerates may be mixed with additional binders and fillers to form an insulating mix that may be used to insulate a furnace or other heat source. A foaming nozzle may be used for the application of agglomerates. A foaming agent and water are air atomized within the foaming nozzle and the resulting foam is mixed into pneumatically conveyed agglomerates, which result results in a lightweight refractory material layer on a target substrate.

Abstract

A valve including a housing, a rotating member positioned within the housing, and an actuator engaged with the rotating member. The rotating member has a generally cylindrical form and a cavity extending through a portion of the generally cylindrical form in a direction generally perpendicular to an axis of the generally cylindrical form. The rotating member is positioned within the housing such that, during operation of the valve, the actuator rotates the rotating member within the housing about the axis of the generally cylindrical form, and upon completion of about 90° of rotation of the rotating member about the axis, the cavity becomes aligned within the housing to change the valve from an open condition to a closed condition, or vice versa. The rotating member includes inorganic fibers and a binder. Methods of making and using the valve are also contemplated.

Abstract

A refractory coating material that can be used to coat a wide variety of surfaces or substrates to provide thermal and mechanical protection. The refractory coating material can withstand exposure to use temperatures of about 1500C and greater, yet the fibers contained therein exhibit low biopersistence in physiological fluids such as simulated lung fluid. Also disclosed are methods for making and utilizing the refractory coating material.
