Verfahren zur Herstellung von Artikeln aus FarbschlammProcess for the manufacture of articles from paint sludge
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Artikeln aus Farbschlamm. Es ist bekannt, daß industrielle Färbeverfahren, wie z. B. Sprühen, Tauchen und elektrostatische Verfahren, große Mengen an Abfall produzieren, die größtenteils in Form eines Schlammes in wäßriger Suspension gesammelt werden.The present invention relates to a method of making articles from paint sludge. It is known that industrial Dyeing processes such as B. Spraying, dipping and electrostatic processes, produce large amounts of waste, most of which are collected in the form of a sludge in aqueous suspension.
Die Verwerfung solcher Schlämme hat immer beträchtliche Probleme in ökologischer und ökonomischer Hinsicht aufgeworfen. Der hohe Prozentsatz an Lösungsmitteln, die Entwicklung ätzender und unangenehmer Dämpfe und die Gegenwart von umweltverschmutzenden Substanzen in der Asche haben z. B. ihre Vernichtung durch Calcinierung teuer und nicht sehr sicher gemacht.The rejection of such sludges has always posed considerable ecological and economic problems. The high percentage of solvents, the development of corrosive and unpleasant fumes and the presence of polluting substances in the ashes have e.g. B. their destruction by calcination expensive and not made very safe.
Die einfachste z.Zeit verwendete Lösung besteht in einer Abladung der Schlämme in geeignete verstärkte Betongefäße, die, wenn sie vollständig gefüllt sind, mit Betondeckeln ver-The simplest solution currently in use is unloading the sludge in suitable reinforced concrete vessels which, when completely filled, are covered with concrete lids.
schlossen und dann eingegraben werden. Es ist klar, daß dies beträchtliche Kosten ohne irgendeinen wirtschaftlichen Gewinn verursacht.closed and then buried. It is clear that this is causes considerable costs without any economic gain.
Es wurden mehrere Versuche unternommen, um den Schlamm nach geeigneter Trocknung und der Zugabe geeigneter Bindemittel zur Herstellung von Platten, die Spanplatten ähnlich sind, zu verwenden, aber die schlechte mechanische Festigkeit solcher Platten zusammen mit den hohen Kosten der notwendigen Anlagen haben schließlich die Anwendung im industriellen Maßstab verhindert.Several attempts have been made to clean up the sludge after suitable drying and the addition of suitable binders to use for the production of panels that are similar to particle board, but the poor mechanical strength such panels together with the high cost of the necessary equipment ultimately have industrial applications Scale prevented.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur industriellen Aufarbeitung von Farbschlamm bereitzustellen, das verwertbare Produkte und damit einen wirtschaftlichen Nutzen ergibt.The object of the present invention is to provide a process for the industrial processing of paint sludge, that results in usable products and thus an economic benefit.
Erfindungsgemäß wird ein Verfahren zur Herstellung von Artikeln aus Farbschlamm bereitgestellt, das gekennzeichnet ist durch die Stufen: Mischen des Schlammes mit wenigstens einem Harz ausgewählt aus einem thermoplastischen Harz und einem hitzehärtenden Harz, Heißextrudieren der Mischung zur Bildung eines Halbfabrikats, und Verarbeitung des Halbfabrikats zu einem Fertigartikel.According to the invention a method for the production of articles provided from paint sludge, which is characterized by the steps of: mixing the sludge with at least a resin selected from a thermoplastic resin and a thermosetting resin, heat-extruding the mixture for Formation of a semi-finished product and processing of the semi-finished product to a finished article.
Die thermoplastischen und hitzehärtenden Harze können ausgewählt sein aus ABS, Polystyrol, Polypropylen, Polyäthylen, Polyamid, Phenolharzen, Harnstoffharzen, Melaminharzen und dergl. Ein Verstärkungsmaterial ausgewählt aus pflanzlichen oder synthetischen Fasern, Fiberglas, Mineralwolle und dergleichen und/oder ein pulverisierter Füller ausgewählt aus Talk, Gips, Calciumcarbonat, Siliciumdioxid, Olivin, Holzmehl und dergleichen kann zusätzlich zum Harz dem Farbschlamm zugegeben werden.The thermoplastic and thermosetting resins can be selected be made of ABS, polystyrene, polypropylene, polyethylene, polyamide, phenolic resins, urea resins, melamine resins and the like. A reinforcing material selected from vegetable or synthetic fibers, fiberglass, mineral wool and the like and / or a powdered filler selected from talc, gypsum, calcium carbonate, silicon dioxide, Olivine, wood flour and the like can be added to the paint sludge in addition to the resin.
Die Stufe des Heißextrudierens stellt sicher, daß die verschiedenen Komponenten homogenisiert werden,und entfernt den Großteil des in der Mischung enthaltenen Wassersund der Lösungsmittel.The hot extrusion stage ensures that the various Components are homogenized, and removes most of the water and contained in the mixture the solvent.
Das aus der Stufe des Heißextrudierens resultierende Zwischenprodukt oder Halbfabrikat kann bei einer Temperatur zwischen 50 und 1300C konditioniert werden, gegebenenfalls im Vakuum, um die Entfernung der Lösungsmittel zu vervollständigen und seine Verformbarkeit vor der Verarbeitungsstufe zu verbessern.The intermediate product or semi-finished product resulting from the hot extrusion stage can be conditioned at a temperature between 50 and 130 ° C., optionally in a vacuum, in order to complete the removal of the solvent and to improve its deformability before the processing stage.
In der nachfolgenden Verarbeitungsstufe wird das Halbfabrikat entsprechend der Art des herzustellenden Fertigartikels (Platten, Folien, Röhren oder Artikel irgendeiner anderen Art oder Form) durch Walzen, Ziehen, Extrudieren oder Formen (mit oder ohne Einspritzung) bei Temperaturen zwischen 100 und 2600C bearbeitet.In the subsequent processing stage, the semi-finished product is processed according to the type of finished article to be produced (sheets, foils, tubes or articles of any other type or shape) by rolling, drawing, extruding or molding (with or without injection) at temperatures between 100 and 260 ° C. .
Die nach dem erfindungsgemäßen Verfahren erhaltenen Fertigartikel sind charakterisiert durch sehr gute mechanische Festigkeit, sehr gute Widerstandsfähigkeit gegenüber atmosphärischen Agentien und sehr gute Dimensionseigenschaften.The finished articles obtained by the process according to the invention are characterized by very good mechanical strength, very good resistance to atmospheric agents Agents and very good dimensional properties.
Es werden nun durch Beispiele drei Arten zur Durchführung des erfindungsgemäßen Verfahrens beschrieben.Three ways of carrying out the method according to the invention will now be described by way of examples.
Es wird eine Mischung hergestellt, die Farbschlamm, 30 % Siliciumdioxidmehl und 30 % ABS-Harz enthält, und diese Mischung wird dann bei einer Temperatur von 1900C extrudiert, um ein Halbfabrikat zu ergeben. Das Halbfabrikat wird bei 700C vier Stunden lang im Vakuum konditioniert und danach im Spritzguß verarbeitet, um Behälter für die elektronische Industrie zu ergeben, die allen artspezifischenA mixture is produced which contains paint sludge, 30% silicon dioxide flour and 30 % ABS resin, and this mixture is then extruded at a temperature of 190 ° C. to give a semi-finished product. The semi-finished product is conditioned for four hours at 70 ° C. in a vacuum and then processed by injection molding in order to produce containers for the electronic industry, all of which are species-specific
Gütetests entsprechen.Conform to quality tests.
Eine Mischung, die Farbschlamm, 40 % Phenolharz und 25 % Mineralwolle enthält, wird bei 700C extrudiert und ergibt ein Halbfabrikat, das nach dem Konditionieren während drei Stunden bei 600C heißextrudiert wird, um Bewässerungsrohre und Verbindungen zu ergeben.A mixture containing paint sludge, 40% of phenolic resin and 25% mineral wool contains, is extruded at 70 0 C, and produces a semi-finished product, which is hot extruded after conditioning for three hours at 60 0 C to give irrigation pipes and connections.
Eine Mischung aus 50 % Farbschlamm, 40 % Phenolharz und 10 ' pflanzlicher Fasern wird extrudiert und konditioniert und dann zur Herstellung flacher Platten verwendet.A mixture of 50% paint sludge, 40% phenolic resin and 10 ' vegetable fibers is extruded and conditioned and then used to make flat sheets.
Alle in der vorliegenden Beschreibung und den Ansprüchen genannten Prozentangaben sind Gewichtsprozente.All mentioned in the present description and claims Percentages are percentages by weight.
