Title
(DE) VERFAHREN ZUR HERSTELLUNG VON FORMKÖRPERN
(EN) METHOD OF PRODUCING MOULDINGS
(FR) PROCEDE DE PRODUCTION DE CORPS MOULES
Abstract
(DE)
Um ein Verfahren zur Herstellung von Formkörpern anzugeben, mit welchem durch Auswahl der verwendeten Rohstoffe (1, 2) bzw. Rohstoff-Kompositionen sowie durch einander angepaßte als auch auf die entsprechenden Rohstoffe (1, 2) abgestimmte Verfahrensschritte gezielt Einfluß auf die technologischen Eigenschaften der Formkörper genommen werden kann, so daß sich die Formkörper mit gewünschten technologischen Eigenschaften mit geringem Energie- und Kostenaufwand herstellen lassen, wird ein Verfahren zur Herstellung von Formkörpern angegeben, wobei zerkleinerte Rohstoffe (1, 2) vermischt, mit mindestens einem Bindemittel (4) aufbereitet, in Formen (5) gepreßt und ausgehärtet werden.
(EN)
The aim of the invention is to provide a method of producing mouldings in which the properties of the mouldings can be influenced, as required, by the selection of the raw materials (1, 2) or raw-material compositions used as well as by matching the steps in the method to each other and to the raw materials (1, 2) so that the articles can be produced with the required technological properties, using little energy and at low cost. This is achieved by mixing the ground raw materials (1, 2) incorporating at least one binder (4), compressing the composition in moulds (5) and curing the mouldings thus formed.
(FR)
L'invention vise à mettre au point un procédé de production de corps moulés, qui permette d'influer de manière ciblée sur les propriétés technologiques desdits corps moulés, grâce à la sélection des matières premières (1, 2) utilisées ou de leurs compositions, ainsi que grâce à des étapes aussi bien adaptées les unes aux autres, qu'aux matières premières (1, 2) correspondantes, de manière à pouvoir produire des corps moulés présentant les propriétés technologiques souhaitées, le plus économiquement possible en termes de dépenses énergétiques et de coûts. A cet effet, l'invention décrit un procédé de production de corps moulés selon lequel des matières premières (1, 2) broyées sont mélangées, préparées avec au moins un liant (4), moulées par pression dans des moules (5), puis durcies.
