Description

Farbige Formteile aus Asbestzement und Verfahren zu ihrer Herstellung Gefärbter Asbestzement wird im allgemeinen durch Zusatz von organischen oder anorganischen Pigmenten zu dem frischen Gemisch aus Asbestfasern und Zement hergestellt. Es ist auch bekannt, der Zementmasse an Stelle der ungefärbten Asbestfasern gefärbte Asbestfasern oder andere beliebig gefärbte Faserstoffe zuzusetzen. Zur Erzielung einer Farbe der gewünschten Intensität ist eine erhebliche Menge der gefärbten Substanzen erforderlich und der Zusatz derselben infolgedessen ziemlich kostspielig. Außerdem wird die Farbe der gefärbten Formteile durch Bewuchs beeinflußt, der sich auf und in der Oberfläche der Materialien entwickelt.Colored molded asbestos cement parts and their manufacturing process Colored asbestos cement is generally made by adding organic or inorganic Pigments made to the fresh mixture of asbestos fibers and cement. It is also known, the cement mass instead of the undyed asbestos fibers dyed asbestos fibers or to add other fibers of any color. To achieve a color the desired intensity requires a considerable amount of the colored substances and, consequently, quite costly to add. It also gets the color of colored moldings influenced by growth on and in the surface of materials developed.

Gegenstand der Erfindung sind Formteile aus farbige Asbestfasern enthaltendem Asbestzement, gekennzeichnet durch eine parasitären Pflanzenwuchs verhindernde Oberflächenschicht aus farbigem amphibolischem Hornblendeasbest, insbesondere Krokydolithasbest oder Amositasbest.The invention relates to molded parts made from colored asbestos fibers Asbestos cement, characterized by a surface layer that prevents parasitic vegetation of colored amphibolic hornblende asbestos, in particular crocidolite asbestos or Amositasbestos.

Zur Herstellung dieser Formteile werden in die Oberflächenschichten der Materialien, zumindest in die Oberflächenschicht der Vorderseite, amphibolischer farbiger Hornblendeasbest, wie Krokydolithasbest oder Amositasbest, eingearbeitet, während die Innenschichten vorzugsweise weißen Serpentinasbest enthalten. Es wurde festgestellt, daß farbiger amphibolischer Asbest die überraschende Eigenschaft hat, die Entwicklung von Parasitenpflanzen, wie Moos, Pilze und Flechten, zu verhindern und diese Pflanzen sogar zu zerstören.For the production of these molded parts are in the surface layers of the materials, at least in the surface layer of the front, more amphibolic colored hornblende asbestos, such as crocidolite asbestos or amosite asbestos, while the inner layers preferably contain white serpentine asbestos. It was found that colored amphibolic asbestos has the surprising property, prevent the development of parasitic plants such as moss, fungi and lichens and even destroy these plants.

Da farbiger amphibolischer Asbest mit Zement zu brüchige Produkte ergeben würde, ist es angezeigt, seine Anwendung auf die Oberflächenschichten zu beschränken und für die Innenschichten üblichen weißen Serpentinasbest vorzusehen, so daß farbige Materialien erhalten werden, die alle Qualitäten der derzeitigen Asbestzementprodukte und die Eigenschaft haben, gegenüber Witterungseinflüssen, sekundären chemischen Einflüssen des Zements und Parasitenpflanzen unempfindlich zu sein.Because colored amphibolic asbestos with cement too fragile products it is appropriate to apply it to the surface layers limit and use the usual white serpentine asbestos for the inner layers, so that colored materials are obtained which have all the qualities of the present day Asbestos cement products and have the property of being exposed to the effects of the weather, insensitive to secondary chemical influences of cement and parasitic plants to be.

Die farbige Oberflächenschicht kann verwirklicht werden, indem man ein Gemisch aus Zement und farbigen Hornblendeasbestfasern auf einer frischen Schicht aus mit Serpentinasbestfasern verstärktem Zement ausbreitet oder um die Trommel einer Pappeherstellungsmaschine eine oder mehrere Lagen legt, die farbige Hornblendeasbestfasern enthalten und mit Hilfe eines Siebzylinders hergestellt worden sind, der in einen Behälter taucht, der ein in Wasser suspendiertes Gemisch von Zement und Mineralfasern enthält. Um diese farbige Schicht legt man dann das Grundgemisch, das die Fasern aus normalem Serpentinasbest enthält. Das die farbige Schicht bildende Gemisch enthält vorteilhaft wenigstens 10% farbige Fasern aus amphibolischem Asbest, um der Oberflächenschicht die gewünschte Farbe zu geben und ihr die Eigenschaft zu verleihen, die Entwicklung von parasitären Pflanzen zu verhindern.The colored surface layer can be realized by a mixture of cement and colored hornblade asbestos fibers on a fresh layer made of cement reinforced with serpentine asbestos fibers or around the drum one or more layers of colored hornblade asbestos fibers on a paperboard making machine included and have been made with the help of a screen cylinder, which is in a Immersed container containing a mixture of cement and mineral fibers suspended in water contains. The basic mixture, which is the fibers, is then placed around this colored layer from normal serpentine asbestos. The mixture forming the colored layer contains advantageously at least 10% colored fibers of amphibolic asbestos around the surface layer to give it the desired color and to give it the quality of development to prevent parasitic plants.
