Description
Oppfinnelsen vedrører et adsorbsjonsmiddel med zeolitisk struktur for å hindre et belegg av de indre glassplateflater av isoleringsglassvinduer fylt med en demmegass med et kondensat samt en anvendelse av adsorbsjonsmiddelet. The invention relates to an adsorbent with a zeolitic structure to prevent a coating of the inner glass plate surfaces of insulating glass windows filled with a dam gas with a condensate as well as a use of the adsorbent.
Isoleringsglassvinduer har to eller flere glassplater som holdes ved hjelp av en avstandsholder og med denne ved hjelp av egnede forseglingsmasser er sammenklebet til en enhet. Insulating glass windows have two or more panes of glass that are held by means of a spacer and with this, by means of suitable sealing compounds, are glued together into a unit.
Det frie rom mellom de til hverandre parallelle plater er vanligvis fylt med luft og i bestemte tilfeller med spesielle gasser. Fyllingen av slike isoleringsglassenheter med spesi-eller gasser istedenfor luft anvendes når det skal oppnås en spesiell høy isolasjonsverdi mot kulde/varme og delvis også The free space between the parallel plates is usually filled with air and in certain cases with special gases. The filling of such insulating glass units with special or gases instead of air is used when a particularly high insulation value against cold/heat is to be achieved and partly also
mot lyd.against sound.
Gassen som innesluttes mellom platene inneholder umiddelbart etter sammenklebning en bestemt fuktighetsmengde. De anvendte tetningsmasser er riktignok i høy grad ugjennomtrengelige overfor vanndamp, tilbakeholder imidlertid allikevel denne ikke fullstendig. Derfor kan det ved temperaturendringer på platens koldeste punkt komme til en kondensasjon av vanndråper så snart platetemperaturen har underskredet dugg-punktet for den vanndampholdige fyllgass. The gas that is enclosed between the plates contains a certain amount of moisture immediately after being glued together. Although the sealing compounds used are largely impermeable to water vapour, they do not retain this completely. Therefore, in the case of temperature changes at the coldest point of the plate, condensation of water droplets can occur as soon as the plate temperature has fallen below the dew point of the water vapor-containing filling gas.
For unngåelse av en slik kondensasjonsprosess innføres tørkemidler i isoleringsglassenheten som adsorberer vann og senker fyllgassens duggpunkt til ekstremt lave verdier således at under de vanlige klimatiske betingelser under den ventede levetid av en slik vindusenhet, opptrer ikke mer vannkondensa-sjon. To avoid such a condensation process, desiccants are introduced into the insulating glass unit which adsorbs water and lowers the dew point of the filling gas to extremely low values so that under the usual climatic conditions during the expected lifetime of such a window unit, no more water condensation occurs.
Vanligvis innføres dette tørkemiddel eksempelvis silicagel eller molekylarsikter i den som hullegemer utformede avstandsholder, idet hulrommet som opptar tørkemiddelet over en sliss eller annen forbindelse er forbundet med gassrommet i isoler- Usually, this desiccant, for example silica gel or molecular sieves, is introduced into the spacer designed as a hollow body, the cavity that receives the desiccant being connected via a slot or other connection to the gas space in the insulating
ingsglassenheten.ing glass unit.
Det finnes nu et stort antall gasser som sammenlignet med luft har en lavere ledningsevne for varme og/eller lyd. Til. anvendelse kommer her spesielt svovelheksafluorid, edelgasser, halogenhydrokarboner samt blandinger av disse' gasser. Ulempen ved alle disse gasser er deres høye pris samt det faktum at deres anvendelse delvis er problematisk av økologiske grunner. Også ved anvendelse av overnevnte gasser som fylling av isoleringsglassenheter er kondensasjon av vann på platenes inner-side ved temperaturveksling uunngåelig. Riktignok kan disse gassers fuktighet holdes meget lav ved ifyIling ved hjelp av deres fortørkning, imidlertid lar inndiffundering av vann gjennom forseglingsmassen i løpet av flere år seg like så lite unngå som ved luftfylt isoleringsglåssenheter. There are now a large number of gases which, compared to air, have a lower conductivity for heat and/or sound. To. particularly sulfur hexafluoride, noble gases, halogenated hydrocarbons and mixtures of these gases are used here. The disadvantage of all these gases is their high price as well as the fact that their use is partly problematic for ecological reasons. Also when using the above-mentioned gases as filling of insulating glass units, condensation of water on the inner side of the plates due to temperature changes is inevitable. Admittedly, the humidity of these gases can be kept very low by ifyIling by means of their drying, however, the indiffusion of water through the sealing compound over the course of several years is as little avoidable as with air-filled insulating glass units.
Dette saksforhold påvirker nu vesentlig valget av det tørke-middel som anvendes. Relativt vidporede tørkemidler som silicagel er uegnet for anvendelsesformålet, fordi de delvis selv adsorberer de omtalte isoleringsgasser eller ved deres adsorbsjonskarakteristikk bevirker en for liten senkning av isoleringsgassens vanndamppartialtrykk, således at det ved temperaturveksling kan komme til en uønsket kodensasjon av vann. This situation now significantly affects the choice of the desiccant used. Relatively wide-pored desiccants such as silica gel are unsuitable for the purpose of application, because they partially themselves adsorb the said insulating gases or, due to their adsorption characteristics, cause a too small lowering of the insulating gas's water vapor partial pressure, so that when the temperature changes, an unwanted co-condensation of water can occur.
Også anvendelsen av molekylarsikter er kritisk. Molekylarsikter med porediametre større eller lik 4A adsorberer alt etter molekylarsikttype, delvis betraktelige mengder av isoleringsgassen ved stor kulde og avgir disse igjen ved oppvarmning, eksempelvis ved solinnstråling. The application of molecular sieves is also critical. Molecular sieves with pore diameters greater than or equal to 4A adsorb, depending on the type of molecular sieve, partly considerable quantities of the insulating gas in extreme cold and emit these again when heated, for example by solar radiation.
Derved er en slik isoleringsglassenhet ofte underkastet ganske betraktelige temperaturbetingede trykksvingninger som kan føre til platenes brudd. Således kan det for det omtalte formål anvendes molekylarsikter med en porestørrelse større enn 4Å ikke alle ønskelige demmegasser. Thereby, such an insulating glass unit is often subjected to quite considerable temperature-related pressure fluctuations which can lead to the plates breaking. Thus, for the mentioned purpose, molecular sieves with a pore size greater than 4 Å can be used, not all desirable dam gases.
I dag anvendes molekylarsikten med porestørrelse på 4å eller også den dyrere 3å. Denne fremgangsmåteteknikk er velkjent og er teknisk anvendt i utstrakt grad. Today, the molecular sieve with a pore size of 4Å or the more expensive 3Å is used. This process technique is well known and is technically used to an extensive extent.
i4u nar det vist seg at det dessuten finnes ytterligere gasser som pga. deres passende varme- og lydledeevne' egner seg til anvendelse som isoleringsgasser. Blant disse gasser skal det spesielt nevnes det billige, overordentlige stabile og sammenligningsmessig økologisk gunstige karbondioksyd. Karbondioksyd har en kritisk molekyldiamter på 3,2Å. i4u when it turns out that there are also additional gases which, due to their suitable heat and sound conductivity' are suitable for use as insulating gases. Among these gases, special mention should be made of the cheap, extremely stable and comparatively ecologically favorable carbon dioxide. Carbon dioxide has a critical molecular diameter of 3.2Å.
Det er nu riktignok kjent at også molekylarsikter av typen K/Na-A-zeolit, såkalt molekylarsikt 3Å ved 20°C og 760 torr adsorberer inntil ca. 7% karbondioksyd i langtidsforsøk. Et vindu utrustet med denne molekylarsikttype og fylt med karbondioksyd som isolerings- eller demmegass ville i løpet av kort tid klappe sammen og dermed ødelegges pga. av dannet undertrykk. It is now known that also molecular sieves of the type K/Na-A zeolite, so-called molecular sieve 3Å at 20°C and 760 torr adsorb up to approx. 7% carbon dioxide in long-term trials. A window equipped with this type of molecular sieve and filled with carbon dioxide as an insulating or damming gas would within a short time collapse and thus be destroyed due to of formed negative pressure.
Av denne grunn kunne anvendelsen av den interessante isoler-ingsgass hittil ikke virkeliggjøres. For this reason, the application of the interesting insulating gas could not be realized until now.
Oppfinnelsen oppgave er nu å tilveiebringe et adsorbsjonsmiddel som muliggjør anvendelsen av en..demmegass med en molekyldiamter i området fra 2, 8Å til 3,5A uten problem og lar seg behandle til en problemløs avvanning uten nødvendighet av en komplisert omstendelig anvendelse av høyvakuum ved en temperatur i området fra 250 til 800°C uten forstyrrelse av krystallstrukturen og som ved sin normale anvendelse har en meget stor vannopptaksreserve. The invention's task is now to provide an adsorbent which enables the use of a..damping gas with a molecular diameter in the range from 2.8Å to 3.5Å without problem and can be processed to a problem-free dewatering without the necessity of a complicated and cumbersome application of high vacuum at a temperature in the range from 250 to 800°C without disturbing the crystal structure and which in its normal use has a very large water absorption reserve.
Denne oppgave løses ifølge oppfinnelsen med et adsorbsjonsmiddel av den innledningsvis nevnte type ved at det består av en hydroksysodalit eller overveiende inneholder dette. According to the invention, this task is solved with an adsorbent of the type mentioned at the outset in that it consists of a hydroxysodalite or predominantly contains this.
Dette adsorbsjonsmiddel har ved 670 torr/25°C en nitrogen-adsorbsjon på maksimalt 0,1 vekt% samt ved 760 torr/25°C This adsorbent has at 670 torr/25°C a nitrogen adsorption of a maximum of 0.1% by weight and at 760 torr/25°C
en karbondioksydadsorbsjon på maksimalt 2 vekt%.a carbon dioxide adsorption of a maximum of 2% by weight.
Oppfinnelsens gjenstand er videre en anvendelse av adsorbsjonsmiddelet ifølge oppfinnelsen et med en demmegass fylt isoleringsglassvindu som erkarakterisert vedat demmegassen til minst 30 volum% er en gass med en molekyldiameter i omrdået fra 2,8 til 3,5A. Av omkostningsgrunner er det hensiktsmessig at demmegassen til minst 30 volum%, fortrinnsvis til minst 70 volum% består av karbondioksyd. The object of the invention is further an application of the adsorbent according to the invention to an insulating glass window filled with a damping gas which is characterized in that the damping gas is at least 30% by volume a gas with a molecular diameter in the range from 2.8 to 3.5A. For cost reasons, it is appropriate that the dam gas consists of carbon dioxide to at least 30% by volume, preferably to at least 70% by volume.
Ved anvendelsen av hydroksysodalit som adsorbsjonsmiddel og karbondioksyd som demmegass har det vist seg at hydroksysodalit med en porediameter på 2,6Å ikke har noen forstyrrende karbondioksyd-sorbsjon. When using hydroxysodalite as adsorbent and carbon dioxide as dam gas, it has been shown that hydroxysodalite with a pore diameter of 2.6Å has no disturbing carbon dioxide sorption.
Hydroksysodalit er et silikat med krystallstruktur og hørerHydroxysodalite is a silicate with a crystal structure and belongs to
til stoffklassen av de zeolitiske molekylarsikter. Hydroksysodalit er definert ved sin kjemiske sammensetning MenO • Al^O^*2Si02• 2,5H20 (idet Me tilsvarer et en- eller toverdi kation) samt dets røntgenstruktur. to the substance class of the zeolitic molecular sieves. Hydroxysodalite is defined by its chemical composition MenO • Al^O^*2Si02• 2.5H20 (where Me corresponds to a monovalent or bivalent cation) as well as its X-ray structure.
Hydroksysodalit adsorberer fremfor alt heller ikke nitrogenAbove all, hydroxysodalite does not adsorb nitrogen either
som har en kritisk molekyldiameter på 3,5Å.which has a critical molecular diameter of 3.5Å.
Således kommer det etter fyllprosessen av isoleringsglassenheter ikke til avgivning av luft som før eller under arb-eidsprosessen ble opptatt av molekylarsikten. Derved unngås den såkalte oppblåsing av isoleringsglassvinduer etter lukking av isoleringsglassenheten. Dette fenomen opptrer når med luft oppladet molekylarsikt kommer i kontakt med den luftfrie iso-leringsglassfremstillingsenhet og dermed pga. av partial-trykkssenkning avgis denne luft etter forsegling av isoleringsglassenheten igjen til isoleringsgassen. Thus, after the filling process of insulating glass units, there is no release of air that before or during the working process was taken up by the molecular sieve. This avoids the so-called inflation of insulating glass windows after closing the insulating glass unit. This phenomenon occurs when the air-charged molecular sieve comes into contact with the air-free insulating glass manufacturing unit and thus due to of partial pressure reduction, this air is released after sealing the insulating glass unit back to the insulating gas.
Et hydroksysodalit i henhold til overnevnte definisjon har følgende sorbsjonsverdier: A hydroxysodalite according to the above definition has the following sorption values:
Vannopptaket er helt tilstrekkelig for anvendelse i isoleringsglassenheten. I tillegg er de to andre anvendelsestekniske rammebetingelser oppfykt,nemlig lite karbondioksyd- og nitrogen opptak. The water absorption is completely sufficient for use in the insulating glass unit. In addition, the two other application technical framework conditions have been met, namely low carbon dioxide and nitrogen uptake.
Det er videre kjent at ved siden av vanndamp kan selvsagtIt is also known that next to water vapor can of course
også andre luftbestanddeler som f.eks. nitrogen og oksygen diffundere gjennom isoleringsglassenhetens forseglingsmasse. Tenker man på at luft har en varmeledeverdi på 56 kalorier/ also other air constituents such as e.g. nitrogen and oxygen diffuse through the insulating glass unit's sealing compound. If you consider that air has a thermal conductivity value of 56 calories/
kg cm 2 og karbondioksyd en slik på 34 kalorier/kg cm 2 sa o er det klart at en inntrengning av luft i de med karbondioksyd fylte isoleringsglassenheter drastisk kan redusere den ønskede varmedemmeeffekten. kg cm 2 and carbon dioxide such as 34 calories/kg cm 2 sa o, it is clear that an ingress of air into the insulating glass units filled with carbon dioxide can drastically reduce the desired thermal insulation effect.
En med karbondioksyd som demmemiddel og med hydroksysodalit som tørkemiddel fylt isoleringsglassenhet kan nu også senere igjen etterfylles med de kjente handelsvanlige karbondioksyd-trykkflasker og en egnet fyllanordning. An insulating glass unit filled with carbon dioxide as a damming agent and with hydroxysodalite as a desiccant can now also be refilled later with the known commercial carbon dioxide pressure bottles and a suitable filling device.
Også ved anvendelsen av andre gasser enn karbondioksyd medfører anvendelsen av hydroksysodalit pga. den ekstremt lille porestørrelse den fordel at praktisk talt ingen iso-leringsgass trenger inn i disse porer og dermed unngås den fryktede katalytiske spaltning av eksempelvis fluor- eller klorholdig isoleringsgasser på tørkemiddelets indre over-flate. Also when using gases other than carbon dioxide, the use of hydroxysodalite causes the extremely small pore size has the advantage that practically no insulating gas penetrates into these pores and thus avoids the dreaded catalytic decomposition of e.g. fluorine- or chlorine-containing insulating gases on the desiccant's inner surface.
Den termiske bearbeidbarhet i et område fra 2 50° til 800°C uten ødeleggelse av krystallstrukturen muliggjør en awann-ing av adsorbsjonsmiddelet for således å omdanne adsorbsjonsmiddelet i dets aktive form. The thermal workability in a range from 250° to 800°C without destruction of the crystal structure enables a dewatering of the adsorbent to thus convert the adsorbent into its active form.
