Description

Opfindelsen angår fibrerbare glasarter, specielt til brug i et centrifugeapparat, der har vertikal akse, og hvori der indføres en strøm af glas, der, når centri-fugeapparatet roterer, rettes mod inderfladen på centri-5 fugelegemets omkredsvæg, hvori der er tilvejebragt et stort antal huller, således at glasset slynges ud og ved udgangen fra disse huller danner glasstråler.
I de sædvanlige anlæg af denne art anvender man sædvanligvis blødt glas, dvs. glasarter af særlig beskaf-10 fenhed til opnåelse af sådanne temperatur- og viskositetsværdier, at glasset frit kan passere gennem hullerne i centrifugelegemet ved en temperatur, der ligger et godt stykke under den temperatur, som centrifugelegemets materiale kan tåle uden alt for stor korrosion og defor-15 mation.
Med henblik herpå tilsættes de anvende glasarter sædvanligvis ret store mængder af en eller flere forbindelser af baryum, bor eller fluor, der bevirker en nedsættelse af smeltetemperaturen, og devitrificeringstem-20 peraturen eller liquidus-temperaturen og af viskositeten og som derfor er effektive midler til, at man undgår at skulle bruge alt for høje glassmeltetemperaturer.
Imidlertid kræver brugen af blandinger, hvori der indgår ret store mængder bor, fluor eller baryum, at der 25 skal tages forholdsregler. Specielt for bor og fluor giver anlægget til produktion af smeltet glas flygtige bestanddele til gene for miljøet, og for ikke at forurene atmosfæren må man sørge for en speciel behandling af de gasarter, der udgår fra anlægget, for herved på passende 30 måde at fjerne disse bestanddele.
I de for tiden anvendte glasarter anvender man f. eks. ca. 3% baryumoxid, og/eller ca. 6% boroxid og/eller ca. 1,5% fluor, men de sædvanligvis anvendte bor- og fluorforbindelser er flygtige ved de temperaturer, der 35 anvendes til fremstilling af glasset, medens fluorforbindelserne er flygtige ved de temperaturer, der gælder for fiberdannelsesprocessen, hvorfor det er nødvendigt fra
.....DK 158578 B
V — 2 starten at anvende tilsætningsmængder under tilberedningen af blandingen. Brugen af ret store mængder af disse stoffer, som er ret kostbare, forøger prisen for de færdige fiberprodukter og de opnåede, relativt bløde glas-5 arter giver fibre, der ikke har hele den ønskede styrke ved de høje temperaturer.
Opfindelsen tager sigte på at afhjælpe disse ulemper.
Opfindelsen tager sigte på at forøge produktionska-10 paciteten hos et givet anlæg til fiberstrækning og giver mulighed for praktisk taget at eliminere visse forureningskilder og for at anvende relativt billige glassammensætninger til fremstilling af fibre, der har bedre styrke ved de høje temperaturer.
15 Med de fibre, der fremstilles med et konventionelt centrifugelegeme og ud fra de kendte glasarter, kan isolationsprodukterne kun bruges ved temperaturer, der ikke er meget højere end 400°C. Med de fibre, der fremstilles ud fra visse glasarter ifølge opfindelsen, kan den til-20 · svarende temperatur nå op til ca. 480°C.
Med hensyn til glassammensætningen - og eksempler herpå vil blive givet senere - er hensigten med opfindelsen at formulere sammensætningen således, at den ikke indeholder fluor·, og heller ikke, eller kun lidt, baryum 25 eller bor. Sådanne glasarter svarer til hårdt glas med højere smelte- og devitrificeringstemperatur.. Dette har til resultat, at- glas sammensætninger uden fluor , bor eller endog uden baryum, der hidtil ikke kunne bruges ved den kendte fibreringsteknik, nu kan bruges til fiber- 30 fremstilling.
Ved i overensstemmelse med opfindelsen i stedet for de konventionelle smeltemidler (B2OBaO, F) at anvende MnO i kombination med ferrioxyd ^62()3) opnår man det, at jernoxydet holdes i ferritilstand og herved gøres mere 35 transparent over for infrarøde stråler i smelteovnen, hvis virkningsgrad herved forbedres. Dertil kommer, at oxyder af jern og mangan ikke er forurenende.

Desuden har disse hårde glasarter den fordel, at de har en større styrke ved høje temperaturer.
Opfindelsen angår således forbedrede fibrerbare glasarter, der er ejendommelige ved den sammensætning, 5 der fremgår af krav 1.
Diverse oplysninger om denne opfindelse findes i det følgende. Alle sammensætninger er angivet i vægtprocent og med forbehold for præcisionen i den foretagne analyse og for de ikke-doserede urenheder.

Inden for de angivne værdiområder foretrækker man 30 dog til fiberfremstilling at anvende glasarter, der er specielt udformede til opretholdelse af ligevægt mellem dels viskositeten, dels devitrificeringstemperaturen og den kemiske modstandsdygtighed overfor vand, hvilken ligevægt er yderst vanskelig at opnå med de hid-35 til kendte glasarter. Man foretrækker især de i krav 4-6 omhandlede glasarter.

Kolonnen A svarer til nye glasarter, der sædvanligvis også indeholder små mængder bor, og hvori der tilsættes små mængder baryum.
Kolonnen B svarer derimod til nye manganglas med 5 større indhold af jern svarende til glasarterne 5, 6 og 7 i tabel I, hvorfra er udelukket enhver tilsigtet tilsætning af baryum og bor, selv om man naturligvis accepterer, at der i hvert fald er spor af sidstnævnte elementer.
Efterfølgende tabel III angiver to sammenlignings-10 eksempler i relation til glassammensætningerne nr. 1 og nr. 2 i FR patentskrift nr. 1.355.739.
Den første søjle i hver gruppe (kendt, hhv. modificeret ved tilsætning af MnO) angiver den teoretiske sammensætning i henhold til nævnte patentskrift, søj-15 lerne A, hhv. C angiver de reelt anvendte sammensætninger i henhold til nævnte kendte glasarter, og søjlerne B, hhv. D angiver sammensætninger i henhold til en modificering, dvs. tilsat 2,5 vægtprocent MnO til erstatning for 2,5 vægtprocent SiC^.
20 En måling - efter Brookfield-metoden - af varia tionerne af viskositeten i afhængighed af temperaturen i temperaturområdet fra 900°C til 1400°C viser, at der for sammensætningerne B og D for den samme viskositetsværdi omkring 1100°C opnås en ca. 40°C lavere tempera-25 tur end for de fra nævnte patentskrift kendte sammensætninger.
En sådan temperaturforskel - for den samme viskosi-tetsværdi - betyder en nemmere fibrering, en forlængelse af centrifugerotorens levetid, udover de tidligere nævn-30 te fordele, der knytter sig til brugen af fluorfrie glasarter.
