Description
Glasskomposisjon for fremstilling av glassfibre. Glass composition for the production of glass fibres.
Oppfinnelsen vedrører glasskomposisjoner for fremstilling av glassfibre omfattende: og komposisjonene er karakterisert ved at de inneholder en mengde Na9 O + K.,0 som holdes mellom 14,1 og 16 vektsprosent og ved at CaO, Na20 4- K2 O og Ba O tilfredsstiller ulikhetene: The invention relates to glass compositions for the production of glass fibers comprising: and the compositions are characterized in that they contain an amount of Na9 O + K.,0 which is kept between 14.1 and 16 percent by weight and in that CaO, Na20 4- K2 O and Ba O satisfy the inequalities :
Slike glasstyper har visse fordelaktige egenskaper, blant hvilke kan nevnes: deres maksimale avglassingshastighet er under 2 mikron pr. minutt, idet det må erindres at denne hastighet svarer til den større veksthastighet av krystalldimensjo-nen, som observeres ved en bestemt temperatur for hver glassart, og som kalles den maksimale avglassingstemperatur. Such glass types have certain advantageous properties, among which can be mentioned: their maximum devitrification rate is below 2 microns per minute, as it must be remembered that this rate corresponds to the greater growth rate of the crystal dimension, which is observed at a specific temperature for each type of glass, and which is called the maximum devitrification temperature.
Den temperatur som svarer til viskosi-teten 1000 poise ligger, for disse glasstypers vedkommende, mellom ca. 1000 og 1200° C. The temperature corresponding to the viscosity 1000 poise is, for these types of glass, between approx. 1000 and 1200° C.
De i henhold til oppfinnelsen fremstilte glasstyper har forskjellige anvendel-sesmuligheter. Spesielt kan de med fordel benyttes for fremstilling av glassfibre. De er særlig egnet til bruk ved slik glassfiber-fabrikasjon hvor man anvender sen tri-fugeringslegemer som består av ildfast stål, på grunn av den forholdsvis lave temperatur som da kreves ved omdannelsen til fibere, og materialenes avglassingshastighet er praktisk talt lik null ved fibertrek-kingstemperaturen. Denne fibertrekkings-temperatur kan være av størrelsesordenen The types of glass produced according to the invention have different application possibilities. In particular, they can be advantageously used for the production of glass fibres. They are particularly suitable for use in such glass fiber fabrication, where late trifugation bodies consisting of refractory steel are used, due to the relatively low temperature that is then required during the conversion to fibers, and the devitrification rate of the materials is practically equal to zero during fiber drawing. the king temperature. This fiber drawing temperature can be of the order of magnitude
1080—1100° C, og kan senkes til 1030— 1050° C eller, for visse glassorters vedkommende, endog til 960—980° C. Det ble fun-net, at på grunn av de i henhold til oppfinnelsen fremstilte glasstypers motstandsevne mot avglassing, unngår man igjen-stopping av de utslyngningsåpninger som 1080-1100° C, and can be lowered to 1030-1050° C or, in the case of certain types of glass, even to 960-980° C. It was found that due to the resistance to devitrification of the glass types produced according to the invention , one avoids re-clogging of the ejection openings which
er anordnet i det nedre parti av sentrifu-geringsanordningen og som regel holdes på en generelt lavere temperatur enn det øverste parti. is arranged in the lower part of the centrifugation device and is usually kept at a generally lower temperature than the upper part.
Glass i henhold til oppfinnelsen, hvis motstandsevne mot avglassing kan være Glass according to the invention, whose resistance to devitrification can be
liten, gjør det følgelig mulig å senke den temperatur ved hvilken sentrifugeappara-turens legemer arbeider, hvilket øker de sistnevntes nyttige levetid. På denne måte kan den midlere nyttige levetid hos sentri-fuger som arbeider med vanlige glasstyper, small, consequently makes it possible to lower the temperature at which the bodies of the centrifuge apparatus work, which increases the useful life of the latter. In this way, the average useful life of centri-joints working with common types of glass,
for fremstilling av glassfibre, stige fra 200 til 300, ja selv til 330 timer. for the manufacture of glass fibres, rise from 200 to 300, even to 330 hours.
Sammensetningen av glasstyper i henhold til oppfinnelsen er slik at disses frem-stillingspris ligger lavere enn for de van-lig anvendte glasstyper. Det bør i denne forbindelse bemerkes at glass i henhold til oppfinnelsen har et meget lavt innhold av borsyreanhydrid og at deres innhold av alkalioksyder er forholdsvis høyt. Også inn-holdet av kalsiumoksyd er lavt, og det samme gjelder magnesiumoksyd; forholdet mellom de to sistnevnte bestanddeler kan The composition of glass types according to the invention is such that their production price is lower than for the commonly used glass types. It should be noted in this connection that glasses according to the invention have a very low content of boric anhydride and that their content of alkali oxides is relatively high. The content of calcium oxide is also low, and the same applies to magnesium oxide; the relationship between the two latter constituents can
/ MgO / / MgO /
med fordel være 0,50 ( —%-—< 0,70. preferably be 0.50 ( —%-—< 0.70.
\ CaO \ \CaO\
Dette forhold mellom kalsiumoksyd og magnesiumoksyd kan fåes ved å benytte dolomitt. Det passende forhold mellom alu-miniumoksyd og natrium- og kalsiumoksyd kan med fordel oppnås ved å anvende phoholith. Bruk av dolomitt og phoholith med-fører dessuten den fordel at glass-smelt-ningsoperasjonen foregår lettere. This ratio between calcium oxide and magnesium oxide can be obtained by using dolomite. The appropriate ratio between aluminum oxide and sodium and calcium oxide can be advantageously achieved by using phoholith. The use of dolomite and phoholith also has the advantage that the glass melting operation takes place more easily.
