摘要:
The invention relates to foams and molded parts made of foamed supporting materials that are selected from the group consisting of polyurethane resins, polyester resins, epoxides, as well as non-woven fabrics, woven materials, and open-cell two- and three-dimensional networks that consist of mineral, animal, plant, and chemical (natural/synthetic) fibers or mixtures thereof containing melamine/formaldehyde resin as a foaming reactive resins.
摘要:
The use of shaped bodies with length, width and height dimensions each in the range from 1 mm to 3 cm as dust binders in vacuum cleaners, wherein the shaped body/bodies is or are produced from chemically untreated open-cell foam with a density in the range from 5 to 500 kg/m3 and a mean pore diameter in the range from 1 µm to 1 mm.
摘要:
The invention relates to a tube which has been filled with an open-cell foam based on an amino resin, especially a melamine/formaldehyde condensation product, and to its uses, especially as a filter or static mixer.
摘要:
The invention relates to a foam material from a foam matrix comprising substantially open cells and a finish from substantially fluorocarbon resin or silicone resin applied to the foam matrix. The finish additionally contains at least one fire-retardant substance. The invention also relates to a method for producing the inventive foam.
摘要:
The invention relates to the use of molded bodies as dust-binding means in vacuum cleaners. The molded bodies according to the invention have length/width/height dimensions ranging from 1 mm to 3 cm, at least one dimension being larger than 5.5 mm, and are produced by treating (a) an open-cell foam material having a density ranging from 5 to 500 kg/m3 and a mean pore diameter ranging from 1 μm to 1 mm (b) with an aqueous formulation of at least one compound having at least one hemiaminal group or aminal group per molecule or at least one copolymer which contains at least one OH group- or β-dicarbonyl group- or epoxy group-containing comonomer polymerized into it, (c) and a shaping step.
摘要:
The invention relates to a method for coating a molded foam part with a plastic film, characterized in that a) the molded foam part is arranged in a capsule and fastened, the plastic film being interposed between the capsule wall and the molded foam part, b) the air in the chamber between the plastic film and the molded foam part is evacuated, c) thereby pressing the plastic film onto the molded foam part, and a vacuum is maintained during the pressing step. The invention also relates molded foam parts that are accessible for the first time by using said method and to the use of said molded foam parts.
