Procédé de production de permutite.
La présente invention a trait à un nouveau procédé de production de pernutite.
Jusqu'à présent, pour l'obtention de permutite, on fondait ensemble: trois parties de kaolin, six parties de quartz et douze parties de soude.
La production de permutite exige une température très élevée, ce qui peut produire dans certains cas, des décompositions et par conséquent des pertes de matières.
La formule chimique de la permutite est :
EMI1.1
2Si 02 -Ai 3 Na?o r 6HyO, relation carac- térisée par un rapport 1 : 1 de Al2O3 et Na2O.
<Desc/Clms Page number 2>
Suivant la présente invention, la soude est remplacée par un mélange de Na2 SO4 et charbon, matières premières d'un prix beaucoup moindre.
Le fait que les matières naturelles phonolithe et cémolithe se trouvent en grandes quantités en Tchécoslo- vaquie et qu'elles ont une composition telle que le rapport Al2O3 et Na20 est pratiquement 1 : 1, comme dans le cas de la permutite, a incité l'inventeur a mettre au point le nouveau procédé décrit ci-après.
Les matières phonolithe et cémolithe utilisées à l'état de verre minéral, lient moléculairement H20.
Deux procédés de fabrication peuvent être mis en oeuvre :
1) Les matières sont mélangées et fondues en présence de Si C, à une température de 1240 C, tout comme le verre multicellulaire. La masse fondue est plongée dans de l'eau exempte de Ca C03et elle est ensuite hydratée en auto clave, par la vapeur d'eau à 210 C. La matière est ensuite broyée et granulée aux dimensions requises.
2) On ajoute aux matières premières : phonolithe ou cémolithe, de l'argile ou du kaolin, de la soude ou du sulfate de soude (2 à 3$1); la température de fusion sera, dans ce cas de 1460 à 1500 C. La masse est ensuite traitée comme décrit sous 1.
La composition chimique de cette permutite sera
EMI2.1
donc : x. SiO 2 -Ai203 - y. H20-
L'emploi d'une quantité de 2 à 3% de soude ou de sulfate de soude suivant la composition de la matière premiè- re utilisée, simplifie grandement la fabrication et réduit sensiblement le prix de revient.
Pour l'obtention de permutite multicellulaire, il est nécessaire de mélanger une petite quantité de Si C à la matière première (phonolithe ou cémolithe).On obtient ainsi des grains multicellulaires présentant une très gran-
<Desc/Clms Page number 3>
de surface de contact.
La régénération de cette permutite se fait de la manière habituelle par Na Cl.
REVENDICATIONS.
1. Procédé de production de perrnutite caractéri- sé par le fait que la matière première utilisée est la phonolithe ou la cémolithe..
<Desc / Clms Page number 1>
A method of producing permutite.
The present invention relates to a novel method for producing pernutitis.
Until now, to obtain permutite, we melted together: three parts of kaolin, six parts of quartz and twelve parts of soda.
The production of permutite requires a very high temperature, which in some cases can lead to decompositions and consequently material losses.
The chemical formula of permutite is:
EMI1.1
2Si 02 -Ai 3 Na? O r 6HyO, relationship characterized by a 1: 1 ratio of Al2O3 and Na2O.
<Desc / Clms Page number 2>
According to the present invention, the soda is replaced by a mixture of Na2 SO4 and carbon, raw materials of a much lower price.
The fact that the natural materials phonolith and hemolith are found in large quantities in Czechoslovakia and that they have a composition such that the ratio Al2O3 and Na20 is practically 1: 1, as in the case of permutite, prompted the inventor has developed the new process described below.
The phonolith and cemolith materials used in the state of mineral glass, molecularly bind H20.
Two manufacturing processes can be implemented:
1) The materials are mixed and melted in the presence of Si C, at a temperature of 1240 C, just like multicellular glass. The melt is immersed in water free of Ca C03 and it is then hydrated in autoclave, with steam at 210 C. The material is then ground and granulated to the required dimensions.
2) We add to the raw materials: phonolith or cemolith, clay or kaolin, soda or sodium sulphate (2 to 3 $ 1); the melting temperature will be, in this case from 1460 to 1500 C. The mass is then treated as described under 1.
The chemical composition of this permutite will be
EMI2.1
therefore: x. SiO 2 -Ai203 - y. H20-
The use of a quantity of 2 to 3% of sodium hydroxide or of sodium sulphate depending on the composition of the raw material used, greatly simplifies the manufacture and appreciably reduces the cost price.
To obtain multicellular permutite, it is necessary to mix a small amount of Si C with the raw material (phonolith or cemolith). This gives multicellular grains with a very large
<Desc / Clms Page number 3>
contact surface.
The regeneration of this permutite is carried out in the usual way with Na Cl.
