Abstract:
An embedded material and an embedding apparatus and method. A compatible solute can be dissolved in a solvent. The object to be embedded can foe coated with the solvent/plastic solution using, for example, addition and/or condensation polymerization. The solvent can be removed. The coated object cart be inserted, snap fit or submerged into a partially 3D printed substrate with or without the aid of ultrasonic embedding, thermal energy, joule heating, and/or the use of adhesives, and the 3D printing process resumes In order to fully embed the coated object within the 3D printed substrate. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the addition of ultrasonic embedding, thermal energy, joule heating, and/or adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate.
Abstract:
Food processing, preparation, and handling devices are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The percentage by weight of the conductive powder(s), conductive fiber(s), or a combination thereof is between about 20% and 50% of the weight of the conductive loaded resin-based material. The micron conductive powders are metals or conductive non-metals or metal plated non-metals. The micron conductive fibers may be metal fiber or metal plated fiber. Further, the metal plated fiber may be formed by plating metal onto a metal fiber or :by plating metal onto a non-metal fiber. Any platable fiber may be used as the core for a non-metal fiber. Superconductor metals may also be used as micron conductive fibers and/or as metal plating onto fibers in the present invention.
Abstract:
A gravure printing roller is manufactured by mounting a core (10), of steel, cardboard or plastics material for rotation, and moving a dispensing head (11) relatively to the core (10) to build up a body (14) of a polyurethane material on the core, and then machining the body (14) to accord with a required diameter. The mixing head combines at least two components of a syntactic or non-syntactic polyurethane immediately before application to the core, and fast reacting amines may be used to produce a gel-like intermediate to aid retention on the core, before complete curing of the polyurethane takes place in the body (14).
Abstract:
Ein Verfahren zum Abreichern von Schwermetallen in löslichen Polymeren, mit den Schritten: - Lösen des Polymermaterials in einem organischen Lösungsmittel; und - Filtern der so erhaltenen Lösung durch ein Filtermaterial, ist dadurch gekennzeichnet, dass die Konzentration in der Lösung von nicht mehr als 20 Gew.- % eingestellt wird und dass als Filtermaterial ein Zellulosefaserfilter mit einer Porengrösse zwischen 1 und 25 µm eingesetzt wird.
Abstract:
The invention relates to a method for separating a waste material including plastic material and metallic material. The method includes the steps: shredding and/or granulating the waste material including plastic and metallic material; mixing and wetting the granulated waste material with process-water; subjecting the granulated waste material to a sink-float process separating the mixture into two fractions having different average densities, the fraction with the lowest average density being designated the light fraction and the other fraction being designated the heavy fraction, removing the light fraction; and subjecting the heavy fraction to treatment on a shaking table separating the heavy fraction into a metallic fraction and a heavy plastic fraction; optionally subjecting the heavy plastic fraction to a second sink-float process.
Abstract:
The invention relates to a method for the treatment of shredder residues from metal-containing waste products, in particular from vehicle chassis, whereby the shredder residue is separated into a shredder light fraction (SLF) and a non-ferromagnetic fraction (shredder heavy fraction (SSF)) and a unit for the treatment of shredder residues from metal-containing waste products, in particular motor vehicle chassis. According to the invention, the primary material streams, arising during the processing of the shredder light fraction (SLF) and the shredder heavy fraction (SSF) in initial processes (VorL, VorS), are fed at least partly to a common main process (SRH) for final processing, whereby at least a ferromagnetic fraction (Fe/V2A), a non-ferrous metal containing fraction (NE), a granulate fraction (Granulate), a lint fraction (Lint) and a sand fraction (Sand) are generated.
Abstract:
The invention relates to an installation for recovering shredder waste or similar composite materials containing metal. The installation is provided with a metal separator (12) positioned upstream of an impact mill (10) and an eddy current separator (34) which is positioned downstream of said impact mill (10) and connected to same by means of at least one return line (38). A classifier (28) is provided for between the impact mill (10) and the eddy current separator (34) and is also connected to said impact mill (10) by means of a further return line (30). The invention also provides for at least one metal separator (12a), notably an iron separator, to be arranged downstream of the impact mill. To recover composite materials not containing metal the metal separator(s) (12, 12a) are bypassed.
Abstract:
The invention relates to a method for recycling used plates (1), wherein used plates (1) are separated from components (6) or parts and are firmly bonded to produce a composite plate. The invention also relates to the composite plate thus produced.
Abstract:
Plastics are separated and recovered from mixtures containing plastics and other materials, by flotation in an aqueous dispersion (28), wherein the disperse phase comprises a substance such as for example calcium carbonate having an average mean particle size from about 1 micron to about 75 microns. The process is particularly useful for separating polyethylene and polyvinyl chloride from comminuted wire and cable scrap.
