Description

Verfahren zur Verbesserung des Trockenverhaltens von. Tonen oder keramischen Massen Es gibt eine ganze Reihe von Tonen und keramischen Massen, die ungünstiges Trokkenverhalten aufweisen. Insbesondere gehören hierher fette, plastische Tone bzw. auch Massen aus solchen, vor allem wenn die letzteren zu dickwandigen Körpern bzw. Körpern großen.Formats- verformt werden.Process for improving the dry behavior of. Clays or ceramic Masses There are quite a few clays and ceramic masses that are unfavorable Exhibit dry behavior. In particular, this subheading includes bold, plastic clays or also masses of such, especially if the latter are too thick-walled bodies or bodies of large format.

Das ungünstige Trockenverhalten: der aus den gekennzeichneten Tonen und Massen bereiteten Formkörper bedingt äußerst langsames, vorsichtiges Trocknen, und selbst dann ist es häufig kaum zu vermeiden, daß Trokkenschäden, wie Verziehen, Rissigwerden usw., ,auftreten.The unfavorable drying behavior: that of the marked clays and masses prepared moldings due to extremely slow, careful drying, and even then it is often difficult to avoid drying damage such as warping, Cracking, etc., occur.

Die Erfindung beseitigt die bestehenden Schwierigkeiten.The invention overcomes the existing difficulties.

Benn Verfahren der Erfindung wird der Ton bzw. die Rohmasse mit mehr Wasser angemacht, als an sich zur Erzielung des formgerechten bzw. plastischen Zustandes erf orderlIch wäre; @es wer den aber gleichzeitig der Rohmasse Elektrolyte zugesetzt, die auf die Masse ansteifend wirken.Benn's method of the invention is the clay or the raw mass with more Water turned on, as in itself to achieve the correct shape or plastic state I would be required; @ But electrolytes are added to the raw material at the same time, which have a stiffening effect on the mass.

D erarüge Elektrolyte sind Kalk, Chloride, Sulfate, Säuren. An Stelle von Kalk könnem auch kalkreiche Stoffe, Portlandzemnent usw, benutzt werden. Kalk selbst kann in der Farm des .gebrannten Kalkes oder auch als Kalkhydrat Verwendung finden.The other electrolytes are lime, chlorides, sulfates, acids. Instead of Lime-rich substances, Portland cement, etc., can also be used for lime. lime itself can be used in the farm of burnt lime or as hydrated lime Find.

Die Wirkung des Verfahrens beruht anscheinend darauf, daß durch den erhöhten Wasserzusatz die Teilchenetwas auseinandergedrängt werden, s,o daß bei der Trocl"nun_g, die natürlich von außen, her b:ego-innt, eine bessere Durchlüftung des Körpers möglich ist. Die ansteifend wirkenden Elektrolyte sind notwendig, um trotz des erhöhten Wasserzusatzes die Verformung unter üblichen, Bedingungen durchführen zu können. Es ist für das Verfahren der Erfindung gleichgültig, ob die Verformung unter Benutzung einer Strangpresse, durch Eindrehen oder Freidrehen der plastischen Masse oder in sonst üblicher Weise :erfolgt. Wesentlich ist nur, daß-in jedem Falle die Rohmasse mit größeren Wassermengen" als an sich zur Verformung notwendig wäre, angemacht wird.The effect of the procedure is apparently based on the fact that the increased addition of water the particles are pushed apart a little, s, o that with the trocl "nun_g, which of course from the outside, her b: ego-innnt, better ventilation of the body is possible. The stiffening electrolytes are necessary to In spite of the increased addition of water, the deformation can be carried out under the usual conditions to be able to. It is unimportant for the method of the invention whether the deformation using an extruder, by screwing in or free turning the plastic Mass or in any other usual way: takes place. It is only essential that in every case the raw mass with larger amounts of water "than would be necessary for deformation, is turned on.

Wie weit mit dem ,erhöhten Wasserzusatz und dementsprechend mit der Menge der zuzusetzenden Elektrolyte im Einzelfall zu gehen ist, ist durch praktische Versuche auszuprobieren. Grundsätzlich gilt di(e Regel, daB der Wasserüherschuß um so größer zu wählen ist, je trockenempfindlicher der Ton bzw. die Masse ist.How far with the, increased water addition and accordingly with the Amount of electrolytes to be added to go in each individual case is, has to be tried out through practical experiments. Basically the rule applies that The greater the water spray, the more sensitive the clay to dryness or the mass is.

Der Zusatz des Elektrolyts kann in irgendeinem Stadium der Masseaufbereitung bzw. -Vorbereitung erfolgen. Es ist beispielsweise möglich, bei der Herstellung von Ziegelnoder Klinkern die Elcktrolyte erst unmittelbar vor Eintritt der Masse in die Strangp.resse zuzugeben, also die Masseaufbereitung mit einer breiig-flüssigen Masse durchzuführen, was u. a. auch den besonderen Erfolg der Ersparnis an mechanischer Kraft für die Aufbereitun- mit sich bringt.The addition of the electrolyte can be done at any stage of the mass preparation or preparation. It is possible, for example, during manufacture of bricks or clinker bricks or clinker bricks, the electrolyte is only added immediately before the mass enters to be added to the Strangp.resse, i.e. the preparation of the mass with a pulpy liquid Perform mass, which i.a. also the particular success of saving on mechanical Strength for the preparation.
