Abstract

Steel girders in building are given fire-protection by spraying them with a compsn. comprising (a) waste prods. from ferrosilicon prodn. (e.g. flue dust emissions), (b) waste prods. from glass fibre or steel wool prodn., (c) binders (e.g. cement and/or chamotte, gypsum produced from exhaust gas desulphurisation, silicates, Al2O3 etc.) and (d) a wetting and/or flocculating agent. Components (a)-(c) are non-recyclable waste prods. which have had no previous use and are cheap, besides having high adhesion, strength, fire-resistance and low density.

Description

Beschreibung und Erl" 7 erung zur PatentanmeldungDescription and explanation of the patent application

WFeuerfeste Masse zum Schutze vorzugsweise für Stahlbaustützen im Hochbau mit Netzmittel und/oder Flockungsmittel" Es ist bekannt, Stahiträger gegen Feuer durch Aufsprühen von feuerhemmendem Material, wie Asbestfasern, die mit Zement vermengt werden, zu schützen.W Fireproof compound for protection, preferably for steel structural supports in Building construction with wetting agents and / or flocculants "It is known to use steel girders against Fire by spraying fire retardant material, such as asbestos fiber, with cement be mingled to protect.

Weiterhin ist bekannt, Asbest-Zementplatten um die zu schützenden Stahlprofile anzuschrauben.It is also known to use asbestos-cement boards around the to be protected To screw on steel profiles.

Der Feuerschutz ist durch diese Masse, dem Stand der Technik entsprechend, gewährleistet.The fire protection is due to this mass, according to the state of the art, guaranteed.

Jedoch ist die zu verwendende Masse sehr teuer.However, the mass to be used is very expensive.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, Massen zu verwenden, die vorzugsweise als Abfallprodukt bei verschiedenen chemischen Prozessen oder Herstellungsverfahren anfallen.For this reason it is proposed according to the invention to use masses preferably as a waste product in various chemical processes or manufacturing processes attack.

Die erfindungsgemäße Masse besteht aus staubhaltigen Produkten, die bei der Ferrosilicium-Herstellung als Emissionsbelastungen anfallen.The mass according to the invention consists of dusty products that occur as emissions in the production of ferrosilicon.

Diese Staubrückstände konnten bisher keiner Verwendung zugeführt werden, da sie a) in den Prozeß nicht rückführbar sind und b) zusätzlich für die Aufhaldung erhebliche Kosten aufgrund ihrer geringen Dichte und ihres somit enormen Eigenvolumens bedeuten.So far, this dust residue could not be used, since they a) cannot be traced back to the process and b) additionally for the dumping considerable costs due to their low density and thus their mean enormous own volume.

Dieses Abfallprodukt hat in Verbindung mit Abfall aus der Glasfaser- oder Steinwollisolier-Matten-Herstellung einen enorm hohen Wärmedämmwert und in zusätzlicher Verbindung mit Zement und Netzmittel und/oder Flockungsmittel ein hohes Haftvermögen sowie eine hohe Festigkeit bei geringer Dichte.This waste product combined with waste from the fiber optic or rock wool insulation mat production has an extremely high thermal insulation value and in additional connection with cement and wetting agents and / or flocculants a high Adhesion and high strength at low density.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, als Feuerschutzmaterial Abfallprodukte zu verwenden, die 1) aus den Prozessen bei der Silicium- oder Ferrosilicium-Herstellung, 2) aus den Prozessen der Stein- und Glaswollmatten-Herstellung anfallen und mit Bindemitteln, Zement, einem Netzmittel sowie Flockungsmittel und/oder artverwandten Stoffen, die gleichzeitig eine zusätzliche feuerhemmende Eigenschaft bewirken, wie Schamotte, Silicate, Aluminiumoxid, CaS04-Abfallprodukte, z.B. aus der S02- und H2S-Entschwefelung von Rauchgasen, gemischt sind.Of course, the invention is not limited to the above in detail The forms of training shown are limited, but there are numerous changes possible, but without deviating from the basic idea, as a fire protection material To use waste products that 1) from the processes involved in silicon or ferrosilicon production, 2) arise from the stone and glass wool mat production processes and with Binders, cement, a wetting agent and flocculants and / or related Substances that also have an additional fire-retardant property, such as Fireclay, silicates, aluminum oxide, CaS04 waste products, e.g. from S02 and H2S desulfurization of flue gases, are mixed.
