Abstract
VarmeisolasjonsplateThermal insulation board
Description
Oppfinnelsen angår en varmeisolasjonsplate fremstilt ved pressing av en blanding av høydispers pyrogen kiselsyre (silica-aerogel) og aluminiumsilikat-ull under tilsetning av et opasitetsmiddel. For en definisjon av begrepet "pyrogen kiselsyre", se Rompps Chemie-Lexicon, 7.opplag, Bd. 5, side 3 2 20„ 1.S<p>alte., The invention relates to a thermal insulation board produced by pressing a mixture of highly dispersed fumed silicic acid (silica airgel) and aluminum silicate wool with the addition of an opacifying agent. For a definition of the term "pyrogenic silicic acid", see Rompp's Chemie-Lexicon, 7th edition, Vol. 5, page 3 2 20„ 1.S<p>alte.,
I de kjente varmeisolasjonsplater benyttes der som opasitetsmiddel TiC^, rutil, ilmenitt, kromoxyd, manganoxyd og jern-oxyd, men også grafitt eller kjønrøk. In the known thermal insulation boards TiC^, rutile, ilmenite, chromium oxide, manganese oxide and iron oxide are used as opacifiers, but also graphite or carbon black.
Av de oppregnede opasitetsmidler kan grafitt og kjønrøk anvendes ved høyere temperaturer kun i konstant fravær av oxygen. I motsatt fall vil nemlig grafitten og kjønrøken omdannes og de-res opasitetsbefordrende egenskaper gå tapt. Tilsvarende gjelder for enkelte av de ovennevnte oxyder, spesielt manganoxyd. Of the opacity agents listed, graphite and carbon black can only be used at higher temperatures in the constant absence of oxygen. Otherwise, the graphite and carbon black will be converted and their opacity-promoting properties will be lost. The same applies to some of the above-mentioned oxides, especially manganese oxide.
Men heller ikke de øvrige opasitetsmidler som anvendes, såsom Ti02, rutil og ilmenitt, gir så gode resultater som man But neither do the other opacity agents used, such as Ti02, rutile and ilmenite, give as good results as
kunne ønske. Ved atmosfæretrykk er nemlig varmeledningsevnen for varmeisolasjonsplater som inneholder slike opasitetsmidler, could wish. Namely, at atmospheric pressure, the thermal conductivity of thermal insulation boards containing such opacifiers,
sterkt avhengig av middeltemperaturen.strongly dependent on the mean temperature.
Her kommer oppfinnelsen inn. Ved hjelp av denne til-veiebringes en varmeisolasjonsplate hvis varmeledningsevne er vesentlig mindre avhengig av middeltemperaturen, og.for hvilken det dessuten kan ventes bedre opasitetsegenskaper, spesielt i høyere temperaturområder fra ca. 400°C og oppover. This is where the invention comes in. With the help of this, a thermal insulation board is provided whose thermal conductivity is significantly less dependent on the average temperature, and for which better opacity properties can also be expected, especially in higher temperature ranges from approx. 400°C and above.
Oppgaven som ligger til grunn for oppfinnelsen løses ved at der som opasitetsmiddel anvendes et carbid av silicium, bor, tantal eller wolfram, alene eller i blanding. The task underlying the invention is solved by using a carbide of silicon, boron, tantalum or tungsten, alone or in a mixture, as an opacifying agent.
Naturligvis er såvel siliciumcarbid som borcarbid dyre-re ved samme finhetsgrad- enn eksempelvis de ovennevnte hittilanvendte opasitetsmidler. Dog har det vist seg, når det gjelder carbider, og spesielt siliciumcarbid, at det kan gjøres bruk av filterstøv fra maleanlegg, som vanligvis ellers ikke finner.noen anvendelse. Dermed har det lykkedes å skaffe industriell anvendelse for et produkt som hittil er blitt betraktet som et av-fallsprodukt, 'og som det forøvrig ikke var helt problemfritt å kvitte seg med på grunn av materialets dårlige evne til å ta opp vann. Gjennom anvendelsen av slike carbider skaffes derved, ved siden av de tekniske forbedringer, også et nyttig bidrag til mil-jøvernet, i og med at disse carbider nu kan føres tilbake til Naturally, both silicon carbide and boron carbide are more expensive at the same degree of fineness than, for example, the above-mentioned opacity agents used so far. However, it has been shown, when it comes to carbides, and especially silicon carbide, that filter dust from painting plants can be used, which normally does not otherwise find any use. Thus, it has been possible to obtain an industrial application for a product which has hitherto been regarded as a waste product, and which was otherwise not entirely problem-free to get rid of due to the material's poor ability to absorb water. Through the use of such carbides, in addition to the technical improvements, a useful contribution to the environment is also obtained, in that these carbides can now be returned to
nyttig produksjon.useful production.
De angitte carbider utmerker seg ved høy termisk og kje-misk stabilitet også ved høyere temperaturer og oppviser d'essuten den nødvendige lave transmisjon i et bredt IR-spektralområde. The indicated carbides are distinguished by high thermal and chemical stability also at higher temperatures and also exhibit the necessary low transmission in a wide IR spectral range.
I den vedføyede grafiske fremstilling vises den typiske ytelse av varmeisolasjonsplater hvor det er anvendt Ti02(kurve 1), siliciumcarbid (kurve 2) og borcarbid (kurve 3). In the attached graphic presentation, the typical performance of thermal insulation boards is shown where Ti02 (curve 1), silicon carbide (curve 2) and boron carbide (curve 3) have been used.
Det vil uten videre sees av den grafiske fremstilling at anvendelse av siliciumcarbid, og spesielt av borcarbid, re-sulterer i tydelig forbedring av varmeledningsevnens -A avhengighet av middeltemperaturen t m, spesielt ved de høyere middeltem-peraturer over 100°C. It will readily be seen from the graphic representation that the use of silicon carbide, and especially boron carbide, results in a clear improvement in the dependence of the thermal conductivity -A on the mean temperature t m, especially at the higher mean temperatures above 100°C.
Selvsagt kan man for varmeisolasjonsplater, som inneholder TiC>2som opasitetsmiddel, forbedre varmeledningsevnen i det øvre temperaturområde ved å øke varmeisolasjonsplatens tett-het. Også her frembyr imidlertid anvendelsen av carbider som opasitetsmiddel en fordel, for så vidt som varmeisolasjonsplater av samme tykkelse blir ca. 60 % lettere', hvilket i mange tilfel-ler er ønskelig. Selvfølgelig kan også varmeisolasjonsplater som er fremstilt under anvendelse av siliciumcarbid eller borcarbid som opasitetsmiddel, forbedres med hensyn til varmeledningsevnens -A avhengighet av middeltemperaturen t , ved at tett-heten økes. Of course, for thermal insulation boards, which contain TiC>2 as an opacifier, the thermal conductivity in the upper temperature range can be improved by increasing the density of the thermal insulation board. Here too, however, the use of carbides as an opacifier offers an advantage, insofar as thermal insulation boards of the same thickness become approx. 60% lighter', which is desirable in many cases. Of course, thermal insulation boards produced using silicon carbide or boron carbide as opacifier can also be improved with respect to the dependence of the thermal conductivity -A on the mean temperature t by increasing the density.
Opasitetsmidlene som anvendes i henhold til oppfinnelsen, bør ha en slik kornstørrelse at den rest som blir tilbake på en DIN-sikt av 10/xm maskevidde, utgjør mindre enn 5 %. The opacity agents used according to the invention should have such a grain size that the residue remaining on a DIN sieve of 10/xm mesh size is less than 5%.
For isolasjonsformål på atomområdet, dvs. for varmeisolasjon av kjernereaktorer av de forskjelligste konstruksjoner i kjernetekniske anlegg og for varmeisolasjon av deler av oppred-ningsanlegg, spesielt når neutronstråling med termisk energi gjør seg gjeldende, oppnåes ytterligere fordeler ved anvendelse av borcarbid, som følge av dets brede virkningsspektrum overfor ter-miske neutroner. For insulation purposes in the nuclear area, i.e. for thermal insulation of nuclear reactors of the most diverse constructions in nuclear engineering facilities and for thermal insulation of parts of reprocessing facilities, especially when neutron radiation with thermal energy is used, further advantages are achieved by using boron carbide, as a result of its broad spectrum of action against thermal neutrons.
To utførelseseksempler skal gies:Two execution examples shall be given:
En varmeisolasjonsplate av følgende sammensetning ble fremstilt: A thermal insulation board of the following composition was produced:

I en annen utførelsesform ble det anvendt:In another embodiment, it was used:
68,4 vekt% pyrogen .kisélsyre68.4% by weight pyrogen .silicic acid
26,04 " borcarbid26.04" boron carbide
5,6 " mineralull5.6" mineral wool
Å anvende carbider i ildfaste isolasjonsmaterialer er i og for seg kjent. Således er det fra US patentskrift nr. 4.014.704 kjent å tilsette siliciumcarbid til et ildfast fiberisolasjonsmateriale bestående i det vesentlige av aluminiumsili-katfibre. Denne masse skal spesielt anvendes for fremstilling av støpetrakter for metallsmelter. Bortsett fra at kornstørrel-sen av det der anvendte siliciumcarbid er vesentlig større enn den som anvendes i henhold til oppfinnelsen, blir det i dette fiberisolasjonsmateriale heller ikke brukt pyrogenkiselsyre eller silika-aerogel som vesentlige bestanddeler. Using carbides in refractory insulation materials is known per se. Thus, it is known from US Patent No. 4,014,704 to add silicon carbide to a refractory fiber insulation material consisting essentially of aluminum silicate fibers. This mass is to be used in particular for the production of casting funnels for metal smelters. Apart from the fact that the grain size of the silicon carbide used there is significantly larger than that used according to the invention, fumed silica or silica airgel are not used as essential components in this fiber insulation material either.
Fra DT-OS nr. 20 05 838 er det kjent et beskyttelses-over trekk for romfartøyer, som er ment å skulle skalle av ved termisk belastning. Her tilsettes siliciumcarbid, siliciumdi-oxyd og høytemperaturbestandige fibre til organo-polyxyloxaner, men siliciumcarbidet skal kun tjene til å forbedre overtrekkets avskallingsegenskaper. Forøvrig er i dette tilfelle silicium-carbidets kornstørrelse vesentlig høyere enn i varmeisolasjons-platen ifølge oppfinnelsen. From DT-OS No. 20 05 838, a protective cover for space vehicles is known, which is intended to peel off in the event of thermal stress. Here, silicon carbide, silicon dioxide and high-temperature-resistant fibers are added to organo-polyxyloxanes, but the silicon carbide should only serve to improve the peeling properties of the coating. Incidentally, in this case the grain size of the silicon carbide is significantly higher than in the thermal insulation plate according to the invention.
