Der Borax-Anteil kann gegebenenfalls auf Kosten höherer Schäumungstemperaturen reduziert werden.The borax component can, if necessary, at the expense of higher foaming temperatures be reduced.
Die Aufbereitung des Ansatzes erfordert normalerweise nur einen Arbeitsgang, wenn die Versatzkomponenten in trockenem Zustand vorliegen, d.h. einen Feuchtigkeitsgehalt von höchstens 1 bis 2 ffi aufweisen und die angegebenen Körnungen besitzen.The preparation of the batch normally only requires one work step, if the Backfill components are in the dry state, i. E. have a moisture content of at most 1 to 2 ffi and the specified Own grits.
Dieser Arbeitsgang besteht in einem homogenen Mischen der trockenen Versatzkomponenten.This operation consists of a homogeneous mixing of the dry Offset components.
Es hat sich gezeigt, daß die sogenannten Chargen-Mischer für diese Mischoperation besonders geeignet sind.It has been shown that the so-called batch mixer for this Mixing operations are particularly suitable.
Zum Zwecke der Herstellung von Formkörpern wird eine abgewogene Menge an Pulvermasse in Formen offener oder geschlossener Bauweise gefüllt und die Pulverschüttung anschließend planiert.For the purpose of producing moldings, a weighed amount is used filled with powder mass in forms of open or closed construction and the powder bulk then leveled.
Der Füllungsgrad der Formen liegt normalerweise zwischen 50 und 85 ffi bei einer Schüttdichte von etwa 1,1 g/cm3.The degree of filling of the molds is usually between 50 and 85 ffi with a bulk density of about 1.1 g / cm3.
Die Formen bestehen aus einem hitzebeständigen bzw. feuerbeständigen Material, da die Pulvermasse in den Formen bei Temperaturen über 1000°C geschäumt wird.The forms consist of a heat-resistant or fire-resistant Material, as the powder mass in the molds foamed at temperatures above 1000 ° C will.
Als Formenmaterial kommen hitzebeständige Stähle oder keramische Werkstoffe auf der Basis von Chamotte-Masse in Frage.Heat-resistant steels or ceramic materials are used as mold materials on the basis of Chamotte mass in question.
Bei großflächigen Formen weist der Formenboden Entlüftungsbohrungen (Lochabstand 9 bis 1o cm, Bohrungsdurchmeser ca. 2 mm) auf, damit sich zwischen Formenboden und schäumender Masse kein Gasdruck aufbaut.In the case of large-area molds, the bottom of the mold has ventilation holes (Hole spacing 9 to 10 cm, hole diameter approx. 2 mm) so that between No gas pressure builds up in the mold bottom and foaming mass.
Die Entlüftungsbohrungen werden vorzugsweise mit einem mikroporösen Papier abgedeckt, um ein Zuschäumen der Bohrungslöcher zu vermeiden.The vent holes are preferably made with a microporous Paper covered to prevent the holes from foaming.
Die Formen werden ferner vorzugsweise mit einem Trennmittel ausgestrichen, um ein Anbacken der Pulvermasse auszuschließen.The shapes are also preferably coated with a release agent, to prevent the powder mass from sticking.
Im folgenden wird die Zusammensetzung eines solchen Trennmittels angegeben, sie lautet: 35 - 45 kg kalzinierte Tonerde, Körnung o,o1-o,lo mm 0,63 kg Tylose 20 ooo 63 kg Wasser 150 cm3 Schwegozid.In the following the composition of such a release agent is given, it reads: 35 - 45 kg calcined clay, grain size o, o1-o, lo mm, 0.63 kg tylose 20,000 63 kg water 150 cm3 Schwegocide.
Bei der Verwendung von Formen aus hitzebeständigem Stahl ist ein müheloses Entformen der geschäumten Körper am besten dann durchzuführen, solange die Formen noch sehr heiß- sind, d.h. zu einem Zeitpunkt, an dem die Formen noch keine wesentliche Kontraktion erfahren haben.Using molds made of heat-resistant steel is an effortless one Demoulding of the foamed body is best then carried out while the molds are still very hot, i.e. at a point in time when the shapes are not yet essential Have experienced contraction.
Bei keramischen Formen kann man dagegen auch im erkalteten Zustand entformen.In the case of ceramic molds, on the other hand, you can also use them when they have cooled down demould.
Zum Aufschmelzen und Schäumen der eingeformten Pulvermassen sind Temperaturen oberhalb 100000 vorzugsweise Temperaturen innerhalb des Temperaturbereichs von 1020 bis 1090°C erforderlich.Temperatures are required for melting and foaming the molded powder masses above 100,000, preferably temperatures within the temperature range of 1020 up to 1090 ° C required.
Die Produktionszeit für geschäumte Körper der Abmessung- 300 x 2oo x 40 bis 70 mm beträgt zwischen 7w5 und 15 Stunden.The production time for foamed bodies of the dimension - 300 x 2oo x 40 to 70 mm is between 7w5 and 15 hours.
Diese Produktionszeit gliedert sich folgendermaßen auf: 1. Aufheizzeit von Raumtemperatur bis auf 1020 bis 1090°C: 1,5 bis 3,0 Stunder 2. Haltezeit bis 1020 bis 1090°C: 1,o bis 2,o Stunden 3. Erste Abkühlperiode von 1020 bis 109000 unter Erstarrungstemperatur: 5 bis lo Minuten 4. Zweite Abkühlperiode bis auf Raumteperatur: 5 bis 1o Stunden Wach Ablauf der Halte zeit sind die geschäumten Körper innerhalb kurzer Zeit, d.h. innerhalb von 5 bis lo Minuten auf ihre Erstarrungstemperatur abzukühlen, um ein Zusammenfallen der kugelförmigen Zellen zu verhindern.This production time is broken down as follows: 1. Heating-up time from room temperature to 1020 to 1090 ° C: 1.5 to 3.0 hours 2. Holding time up to 1020 to 1090 ° C: 1, o to 2, o hours 3. First cooling period from 1020 to 109000 below solidification temperature: 5 to lo minutes 4. Second cooling period down to room temperature: The foamed bodies are within 5 to 10 hours awake after the holding time has elapsed in a short time, i.e. within 5 to 10 minutes to their solidification temperature to cool to prevent the spherical cells from collapsing.
