摘要:
An acoustically absorbent porous panel formed from a cured aqueous foamed cementitious material comprising on a wet basis of about 53% to about 68% by weight cement, about 17% to about 48% by weight water, about 0.05% to about 5% by weight fiber, and about 0.01% to about 10% by weight surfactant. The panel also has pores distributed within the cured material comprising about 75% to about 95% by volume of the material. The cement-based, foamed panel provides good acoustical performance with enhanced durability and moisture resistance.
摘要:
Disclosed is a multi-layered, substantially rigid and self-supporting acoustical panel. Preferably, the panel includes an acoustically absorbent semi-rigid core having a substantially continuous interior porosity. The panel also includes an acoustically permeable face layer applied to a first face of the core, wherein the face layer is adapted to allow acoustical energy to pass through the face layer and into the acoustically absorbent core. The panel also includes a flame-retardant, calendered paper backing adapted to be applied to the core. According to the present invention, the panel may also include a flame-retardant adhesive adapted to attach the calendered, flame-retardant paper backing to the core.
摘要:
This invention is an acoustic fiber-based substrate composed primarily of insulation-type spun fibers or blends of such fibers and wheel spun fibers. The fibers are bound with a water-dispersible latex binder, or an agri-binder such as starch in conjunction with cellulose fiber. The insulation-type spun fibers can be first quality virgin, post-industrial waste-stream or post-consumer waste stream fiber. The substrate is wet-formed from a very dilute aqueous dispersion of ingredients onto a mesh forming screen, as on a Fourdrinier paper machine. By virtue of the insulation-type spun fiber dimensions, morphology and orientation: very low density wet-mats can be formed from a sufficiently dilute suspension. With respect to other wet-formed substrates, the invention is much lower in density and more highly porous, and, thus, the substrate is highly absorbing, exhibiting noise reduction coefficients, NRC values of about 0.80 or greater. Such NRC values have only been achieved with dry-formed, or air-laid processes in which the fiber are bound with formaldehyde emitting reactive resins.

摘要:
Mineral paper is provided which comprises a wet-laid sheet of 1) fibers, 2) a floc of a silicate selected from the group consisting of mica and vermiculite, the said floc having a cationic polymeric flocculant having a molecular weight in the range of from about 10,000 to about 1,000,000, and 3) a non-ionic polymeric flocculant having a molecular weight of from about 2,000,000 to about 10,000,000. A process is described herein for the preparation of the paper using the two flocculants by first flocculating with the cationic polymeric flocculant and then flocculating in another step with the non-ionic polymeric flocculant to obtain an easily drained flocculated mixture which is dewatered to obtain the mineral paper.
摘要:
The present invention provides for an acoustically absorbent porous panel that is both rigid and resistant to sagging caused by moisture. The acoustically absorbent porous panel is comprised of at least two layers. The first layer is a facing layer formed from a cured aqueous foamed cementitious material. The foamed cementitious material comprises on a wet basis about 53% to about 68% by weight cement, about 17% to about 48% by weight water, about 0.05% to about 5% by weight fiber, and about 0.01% to about 10% by weight surfactant. Additionally, pores distributed within the cured material comprising about 75% to about 95% by volume of the material. The second layer is a backing layer that is affixed to the facing layer.
摘要:
A high melting solid aromatic or cycloaliphatic azole-based chemical embossing inhibitor is essentially insoluble and inert in water and/or water alcohol mixtures. These solid azoles can be readily micronized and dispersed into water-based printing inks for use in producing textured foamed plastic surfaces. These compounds comprise a general class of 1-N substituted aminomethylaryl- or cyclohexyltriazole and imidazole derivatives. Some of the preferred compounds are symmetrical di-functional triazole derivatives and some of the preferred embodiments have a carboxy moiety or a sulfonyl moiety attached to a nitrogen atom.
