Description

Verfahren zur Herstellung von Ziegelforrnkörpern Bekanntlich lassen sich Ziegelsteine im Trocken-und Halbnaßpreßverfahren unter Anwendung von Drücken über wo kg/cm2 herstellen. In der Regel wird hierzu staubfein aufbereiteter Ton verwendet. Die Schwierigkeiten dieser Verfahren liegen außer in einer hohen Maschinenabnutzung vor allem in der Erreichung eines spannungsfreien und frostfesten Formkörpers.Let process for the production of brick moldings known bricks in the dry and semi-wet pressing process with the application of pressure about where to manufacture kg / cm2. As a rule, this is done using fine-grained clay used. The difficulties with these methods lie in addition to high machine wear especially in achieving a tension-free and frost-resistant molded body.

Wenn man Material von der Abbauwand ohne weitere Aufbereitung verwendet, und so niedere Drücke anwendet, daß die natürliche Struktur der Tone oder keramischen Rohstoffe nicht wesentlich gestört wird, erhält man Formkörper, die bei hohen Druckfestigkeiten eine ausgezeichnete Frostsicherheit gewährleisten. Nach diesem Verfahren lassen sich großformatige Formkörper, z. B. gebrannte Hohlblockziegel, beliebiger Abmessungen spannungsfrei herstellen. Die Preßdrücke liegen in der Regel hierbei unter 30 kg/em2. Die erreichten Raumgewichte der Formkörper lassen sich mit auf Grund der durch das Tonmineral gegebenen Haufwerksporosität unter iooo kg/cbm halten.If you use material from the excavation wall without further processing, and apply such low pressures that the natural structure of the clays or ceramic raw materials is not significantly disturbed, you get moldings that ensure excellent frost resistance with high compressive strengths. According to this method, large-format moldings, for. B. fired hollow block bricks, any dimensions produce stress-free. The pressing pressures are usually below 30 kg / em2. The density of the molded bodies achieved can be kept below 100 kg / cbm due to the bulk porosity given by the clay mineral.
