Description

Oppfinnelsen angår en tørrmasse for anvendelse i sprøytemasser for fremstilling av ildfaste eller ildbestandige foringer, inneholdende keramiske fibre, bindemiddel og andre vanlige tilsetningsmidler. The invention relates to a dry compound for use in spray compounds for the production of refractory or refractory linings, containing ceramic fibres, binders and other common additives.

Det er kjent å anvende keramiske fibre i såkalte fiber-sprøytemasser. For dette formål blir keramiske fibre enten først blandet med store mengder vann og derefter ved hjelp av en sprøyteinnretning sprøytet på loddrette vegger eller på tak for å danne en ildfast eller ildbestandig foring eller sprøytet inn i hulrom. It is known to use ceramic fibers in so-called fiber spray compounds. For this purpose, ceramic fibers are either first mixed with large quantities of water and then, by means of a spraying device, sprayed on vertical walls or on ceilings to form a refractory or fire-resistant lining or sprayed into cavities.

Således er fibersprøytemasser kjente fra vesttysk ut-legningsskrift 26 18 813 som foruten en større andel av uorganiske fibre og små andeler av bindemiddel hhv. andre uorganiske tilsetningsmidler også inneholder et kjemisk til-satsbindemiddel, idet disse fibersprøytemasser inneholder 5-20 vekt% av en olje for å unngå støvdannelse. Thus, fiber spray compounds are known from West German publication 26 18 813 which, in addition to a larger proportion of inorganic fibers and small proportions of binder or other inorganic additives also contain a chemical additive binder, as these fiber spray masses contain 5-20% by weight of an oil to avoid dust formation.

Ved en annen metode blir tørre keramiske fibre på den ene side og vann på den annen side tilført til hodet for en sprøyteinnretning, blandet med hverandre i sprøyteinnret-ningens hode og derefter sprøytet på loddrette vegger eller tak eller sprøytet inn i hulrom. Det er dessuten kjent å tilsette ytterligere tilsetningsmidler, som bindemidler og a,ndre vanlige tilsetningsmidler, til den ovenfor beskrevne oppslenyning av keramiske fibre i vann. In another method, dry ceramic fibers on the one hand and water on the other hand are supplied to the head of a spraying device, mixed with each other in the head of the spraying device and then sprayed on vertical walls or ceilings or sprayed into cavities. It is also known to add further additives, such as binders and other common additives, to the above-described softening of ceramic fibers in water.

På grunn av de store vannmengder som var nødvendige ved påsprøytingen, var det imidlertid vanskelig homogent å blande disse tilsetningsmidler, som bindemidler og andre vanlige tilsetningsmidler, med fibrene i sprøyteinnretningen og å oppnå en godt vedheftende, påsprøytet masse. However, due to the large amounts of water that were necessary during the spraying, it was difficult to homogeneously mix these additives, such as binders and other common additives, with the fibers in the spraying device and to obtain a well-adherent, sprayed-on mass.

Det tap ved den foreliggende oppfinnelse sikte på å tilveiebringe en tørrmasse eller tørrblanding for anvendelse som fibersprøytemasser som inntil en tykkelse av 30 cm kan påføres såvel på vegger av blikk som på murverk. Dessuten skal en masse tilveiebringes som straks og uten spesiell tørking kan oppvarmes til høyere temperaturer. The purpose of the present invention is to provide a dry mass or dry mixture for use as a fiber spray mass which can be applied up to a thickness of 30 cm both on tin walls and on brickwork. In addition, a mass must be provided which can be heated to higher temperatures immediately and without special drying.

Denne oppgave løses ved den ovenfor beskrevne tørrmasse eller tørrblanding som er særpreget ved de i krav l's karakteriserende del angitte trekk. This task is solved by the dry mass or dry mixture described above, which is characterized by the features specified in the characterizing part of claim 1.

Foretrukne utførelsesformer er angitt i kravene 2-4.Preferred embodiments are specified in claims 2-4.

De keramiske fibre eller mineralfibre som er tilstede i tørrblandingen ifølge oppfinnelsen, kan være alle vanlige fibre av denne type, f.eks. stenull eller fibre på basis av aluminiumsilikat med spesielt høyt A^O^-innhold innen området fra 45 til 95 vekt%. Selvfølgelig kan også bland- The ceramic fibers or mineral fibers which are present in the dry mixture according to the invention can be all common fibers of this type, e.g. rock wool or fibers based on aluminum silicate with a particularly high A^O^ content in the range from 45 to 95% by weight. Of course, mixing can also

irigér av forskjellige keramiske fibre anvendes.irrigates of different ceramic fibers are used.

Ved en fordelaktig utførelsesform av tørrmassene ifølge oppfinnelsen foreligger de keramiske fibre som oppslåtte fibre. For dette formål blir i handelen vanlige fibre i den tilstand de leveres innført i et turboblandeapparat (turbulent-hurtigblandeapparat av typen Drais) i hvilket fibrene som vanligvis leveres som fiberknipper, blir omvandlet til oppslåtte fibre. Et slikt turboblandeapparat består av et blandeaggregat med hurtigroterende knivhoder, hvorved eventuelle forekommende agglomerater i de i handelen vanlige fibre som delvis foreligger i sterkt sammenpresset tilstand, blir slått opp uten at fibrene derved blir for sterkt slått i stykker eller knust. In an advantageous embodiment of the dry masses according to the invention, the ceramic fibers are present as twisted fibres. For this purpose, commercially available fibers in the condition in which they are delivered are introduced into a turbomixer (turbulent rapid mixer of the Drais type) in which the fibers that are usually supplied as fiber bundles are converted into split fibers. Such a turbomixer consists of a mixing unit with fast-rotating knife heads, whereby any agglomerates that may occur in commercially available fibers that are partly in a highly compressed state are broken up without the fibers being thereby too strongly broken into pieces or crushed.

Leiren som foreligger i tørrmassen ifølge oppfinnelsen, kan være en vanlig leire eller en spesiell bindeleire, f.eks. bentonitt. Denne leire blir vanligvis anvendt i en mengde av 5-20 vektdeler pr. 100 vektdeler av de keramiske fibre, og fortrinnsvis blir 8-15 vektdeler leire anvendt. The clay present in the dry mass according to the invention can be a normal clay or a special binding clay, e.g. bentonite. This clay is usually used in an amount of 5-20 parts by weight per 100 parts by weight of the ceramic fibres, and preferably 8-15 parts by weight of clay are used.

De bestanddeler som eventuelt foreligger i de foreliggende masser og som utgjøres av meget findelt A^O^ og/ eller meget findelt SiC^og/eller aluminiumhydroxyder og/ eller meget, findelt magnesiumoxyd og/eller meget findelt titandioxyd og/eller meget findelt kromoxyd, er kjente anvendte bestanddeler innen området ildfaste produkter. The components that may be present in the present masses and which consist of very finely divided A^O^ and/or very finely divided SiC^ and/or aluminum hydroxides and/or very finely divided magnesium oxide and/or very finely divided titanium dioxide and/or very finely divided chromium oxide, are known components used in the field of refractory products.

Med det her anvendte uttrykk "meget findelt" i sammenheng med de ovennevnte bestanddeler skal det forstås at disse bestanddeler foreligger i meget finmalt eller også i kolloidal tilstand. Spesielt for anvendelse av slike materialer som foreligger i kolloidal tilstand, som kolloidalt SiC>2 hhv. kolloidalt aluminiumoxyd, er. det mulig å anvende b<*>are små mengder av bindemiddel, nemlig nær ved den nedre grense- With the expression "very finely divided" used here in connection with the above-mentioned components, it is to be understood that these components are present in a very finely ground or colloidal state. Especially for the use of such materials which are in a colloidal state, such as colloidal SiC>2 or colloidal aluminum oxide, is. it is possible to use only small amounts of binder, namely close to the lower limit

verdi av 1 vektdel av et organisk bindemiddel og 2 vekt-value of 1 part by weight of an organic binder and 2 parts by weight

deler av et fosfatbindemiddel. Anvendelsen av tilnærmet like vektdeler av fosfatbindemiddel og methylcellulose som organisk bindemiddel er spesielt foretrukken. De€ er også spesielt fordelaktig å anvende en blanding av leire og ett eller flere av de ovennevnte andre meget findelte ildfaste bestanddeler, idet mengden av disse andre meget findelte ildfaste bestanddeler vanligvis utgjør 1-3 vektdeler og resten består av leire, slik at en samlet mengde av 2-20 vektdeler ildfaste bestanddeler er tilstede. Dessuten er 0-10 vektdeler sjamottemel tilstede i de foreliggende tørr-masser. Det kan da dreie seg om en hvilken som helst ønsket finmalt sjamotte, og fortrinnsvis har melet en maksimal kornstørrelse av<63^um, og spesielt foretrukket < 44^,um. parts of a phosphate binder. The use of approximately equal parts by weight of phosphate binder and methylcellulose as organic binder is particularly preferred. It is also particularly advantageous to use a mixture of clay and one or more of the above-mentioned other very finely divided refractory components, the amount of these other very finely divided refractory components usually being 1-3 parts by weight and the rest consisting of clay, so that a total amount of 2-20 parts by weight of refractory components is present. In addition, 0-10 parts by weight of chamotte flour are present in the present dry masses. It can then be any desired finely ground chamotte, and preferably the flour has a maximum grain size of <63 µm, and particularly preferably <44 µm.

I de foreliggende tørrmasser er dessuten 2-8 vektdeler, fortrinnsvis 3-6 vektdeler, av et fosfatbindemiddel tilstede, idet de angitte vektdeler er basert på P2^5 ^e*- angjeldende bindemiddel. In the present dry masses, 2-8 parts by weight, preferably 3-6 parts by weight, of a phosphate binder are also present, the stated parts by weight being based on the P2^5 ^e*-related binder.

Eksempler på slike fosfatbindemidler er natriumpolyfosfat med en polymerisasjonsgrad av n — 4, fortrinnsvis med en polymerisasjonsgrad av 6-10. Dette natriumpolyfosfat anvendes i fast form. Et ytterligere fosfatbindemiddel er monoaluminiumfosfat som er et vanlig handelsprodukt i fast, malt tilstand. Examples of such phosphate binders are sodium polyphosphate with a degree of polymerization of n — 4, preferably with a degree of polymerization of 6-10. This sodium polyphosphate is used in solid form. A further phosphate binder is monoaluminium phosphate which is a common commercial product in a solid, ground state.

I de foreliggende tørrmasser forekommer et fast organisk bindemiddel. For dette formål kan alle på dette område vanlig anvendte organiske bindemidler anvendes, f.eks. methylcellulose, sulfittavlut eller melasse. A solid organic binder occurs in the present dry masses. For this purpose, all organic binders commonly used in this area can be used, e.g. methylcellulose, sulphite liquor or molasses.

Fremstillingen av de foreliggende tørrmasser utføres slik at de enkelte bestanddeler tilsettes til et blandeapparat i hvilken som helst ønsket rekkefølge. For dette formål kan et vanlig blandeapparat eller også et turboblandeapparat, som ovenfor beskrevet, anvendes. Istedenfor å anvende allerede oppslåtte fibre for fremstilling av de foreliggende tørrmasser kan også vanlige handelstilgjengelige keramiske fibre innføres i et slikt turboblandeapparat sammen med de andre bestanddeler og oppslåingen av de keramiske fibre bg deri intime blanding med de andre bestanddeler ut-føres i dette. The production of the present dry masses is carried out so that the individual components are added to a mixing device in any desired order. For this purpose, a normal mixer or a turbo mixer, as described above, can be used. Instead of using already broken up fibers for the production of the present dry masses, ordinary commercially available ceramic fibers can also be introduced into such a turbomixer together with the other components and the breaking up of the ceramic fibers bg therein intimate mixing with the other components is carried out therein.

De foreliggende tørrblandinger kan sprøytes med en vanlig sprøytemaskin, som vanlig er ved bearbeiding av The available dry mixes can be sprayed with a normal spraying machine, which is usual when processing

betong. Det vann som er nødvendig for bindingen, blir da tilført til sprøytemunnstykket. Da de foreliggende tørr-masser allerede foreligger som en intim blanding med de homogent fordelte bindemidler,.er den vannmengde som er nødvendig for påføringen, langt lavere enn for tidligere kjente tørrmasser som likeledes sprøytes på denne måte. concrete. The water required for the bond is then supplied to the spray nozzle. As the present dry masses already exist as an intimate mixture with the homogeneously distributed binders, the amount of water required for the application is far lower than for previously known dry masses which are likewise sprayed in this way.

Oppfinnelsen vil bli nærmere beskrevet ved hjelp av de nedenstående eksempler. The invention will be described in more detail using the examples below.

I eksemplene ble keramiske fibre A og B anvendt som hadde følgende kjemiske sammensetning: Fibre A) A1203= 47%, Si02= 53%; In the examples, ceramic fibers A and B were used which had the following chemical composition: Fibers A) A12O3= 47%, Si02= 53%;

Fibre B) Al2°3= 95%'Si02= 5%*Fibers B) Al2°3= 95%'Si02= 5%*

Disse bestanddeler ble grundig blandet med hverandre i 20 minutter i et blandeapparat av typen Eirich. These ingredients were thoroughly mixed together for 20 minutes in an Eirich mixer.

Tørrblandingen ble sprøytet i en sprøytemaskin, idet den ble tilført til munnstykket med trykkluft og i dette blandet med det likeledes tilførte vann. The dry mixture was sprayed in a spraying machine, as it was supplied to the nozzle with compressed air and in this mixed with the likewise supplied water.

Med denne tørrmasse kunne påsprøytede skikt med en tykkelse av 30 cm fremstilles' på loddrette blikkvegger. Den påsprøytede masse kunne straks oppvarmes uten spesiell tørk-ing. En slik påsprøytet masse oppviste de følgende egenskaper: With this dry mass, sprayed-on layers with a thickness of 30 cm could be produced on vertical tin walls. The sprayed-on mass could be immediately heated without special drying. Such a sprayed-on mass exhibited the following properties:

i.b. = ikke bestembar i.b. = not determinable

Eksempel 2 Example 2

Følgende sats ble anvendt: The following rate was applied:

Først ble de keramiske fibre omvandlet til oppslåtte fibre i løpet av 15 minutter i et turboblandeapparat. Derefter ble de andre bestanddeler tilsatt og blandet i ytterligere 3 minutter i turboblandeapparatet. First, the ceramic fibers were converted into spun fibers within 15 minutes in a turbomixer. Then the other ingredients were added and mixed for a further 3 minutes in the turbo mixer.

Efter bearbeidelsen i overensstemmelse med den arbeids-metode som er angitt i eksempel 1, ble de følgende egenskaper bestemt for tørrmassen som var blitt bearbeidet til fiber-sprøytemasse: After the processing in accordance with the working method indicated in example 1, the following properties were determined for the dry mass that had been processed into fiber injection mass:
