Abstract
Fremgangsmåte for fremstilling av lamellplater av mineralull e.l. uten overflatesjikt.Procedure for the production of lamella plates of mineral wool etc. without surface layer.
Description
Mineralull fremstilles ved spinning under anvendelse av maskinelt utstyr, som omdanner den smeltede mineralmasse til fine fibre, hvilke slynges ned på et vandrende bånd. Fibrene legger seg da i sloyfer eller bukter på båndet, og den dannede mineralullfilt eller -matte får derved en preget sjiktning i et plan, som i det minste tilnærmelsesvis ligger parallelt med båndets plan. Mineral wool is produced by spinning using mechanical equipment, which converts the melted mineral mass into fine fibres, which are wound down on a traveling belt. The fibers are then laid in sloys or bends on the belt, and the formed mineral wool felt or mat thereby acquires an embossed layering in a plane, which lies at least approximately parallel to the plane of the belt.
For adskillige formål har de produkter, som ved komprimering og fiksering fremstilles av slik filt eller matte, tilfredsstil-lende og formålstjenlige egenskaper. Det foreligger imidlertid formål, for hvilke disse egenskaper ikke er hensiktsmessige. For several purposes, the products which, by compression and fixing, are produced from such felt or mat, have satisfactory and expedient properties. However, there are purposes for which these properties are not appropriate.
Blant annet må nevnes at de nettopp nevnte produkter er betyde-lig lettere komprimerbare vinkelrett på fiberplanet enn parallelt med dette. Among other things, it must be mentioned that the products just mentioned are significantly easier to compress perpendicular to the fiber plane than parallel to it.
Det har vært foreslått når man ikke onsker denne mulighet til lett komprimering, å fremstille en av lameller sammensatt mineralullplate, hvilket i praksis har medfort at man av det opprinnelig foreliggende mineralullprodukt har skåret ut lameller eller "strimler" ved hjelp av snitt, som har gått vinkelrett på It has been proposed, when this possibility of easy compaction is not desired, to produce a mineral wool plate composed of lamellae, which in practice has meant that lamellas or "strips" have been cut out of the originally available mineral wool product by means of cuts, which have gone perpendicular to
det opprinnelige produkts plan, men man har vendt de derved frembragte strimler 90° om sin egen lengdeakse, og man har derpå the plan of the original product, but the resulting strips have been turned 90° around their own longitudinal axis, and then
foyet dem sammen igjen en efter en, f.eks. ved limstoff eller annet adhesjonsmiddel, av og til under tilfoyelse av et i den blivende, tverrlaminerte plates plan gående belegg eller en stotte i form av kraftpapir, vevet stoff e.l. Slike lamellerte mineralullprodukter har stort sett blitt anvendt som rorisolering, såkalte rorskåler. For tilveiebringelse av den best mulige isolasjonsvirkning har man da komprimert mineralullen for oppkapping i strimler, vending og fornyet sammenfoy-ning, og man har forsynt produktet med belegg bare på en side, nemlig den side som i den blivende rorskål skal vende innover. Kompresjonstrykket har derfor på de enkelte lameller eller strimler virket i en retning, som i den ferdige rorskål ligger peri-ferielt. Mineralullproduktets evne til elastisk å gjeninnta sin opprinnelig foreliggende porositet er da blitt benyttet slik at belegget har hindret at innsiden har utvidet seg, mens den ikke belagte ytre side har utvidet seg, hvorved rorskålen er blitt istand til å anta en avrundet form som omslutter roret. joined them together again one by one, e.g. with glue or other adhesion agent, occasionally with the addition of a coating running in the plane of the remaining cross-laminated board or a support in the form of kraft paper, woven fabric etc. Such laminated mineral wool products have mostly been used as rudder insulation, so-called rudder bowls. In order to provide the best possible insulation effect, the mineral wool has been compressed for cutting into strips, turned and rejoined, and the product has been provided with a coating only on one side, namely the side that will face inwards in the remaining tiller. The compression pressure has therefore acted on the individual slats or strips in one direction, which in the finished rudder cup lies peripherally. The mineral wool product's ability to elastically regain its original porosity has then been used so that the coating has prevented the inside from expanding, while the uncoated outer side has expanded, whereby the rudder bowl has been able to assume a rounded shape that encloses the rudder.
Det.forekommer ofte at man av en eller annen grunn onsker å fremstille mineralullstrimlene på et forste sted og anbringe dem-i kontakt med et annet materiale på et andre sted. It often happens that for one reason or another it is desired to produce the mineral wool strips in a first place and place them in contact with another material in a second place.
Behov foreligger således for et lamellert, plant mineralull-uten overflatesjikt og There is thus a need for a laminated, flat mineral wool - without a surface layer and
produkt/som ikke bor være komprimert. Dette gjelder nar mine-ralullproduktet er beregnet som byggeelement, f.eks. som hori-sontalt liggende varme- eller lydisoleringssjikt i bjelkelag o.l. For dette formål har man tidligere anvendt ferdige elementer, i hvilke man anordnet mineralullmatten i lamellert form. Det foreligger derfor behov for et isoleringssjikt med de for lamellplatene typiske egenskaper, nemlig stivhet, kon-sentrert til en retning på tvers av produktets plan. product/which should not be compressed. This applies when the mineral wool product is intended as a building element, e.g. as a horizontally lying heat or sound insulation layer in joists etc. For this purpose, ready-made elements have previously been used, in which the mineral wool mat was arranged in laminated form. There is therefore a need for an insulation layer with the properties typical of lamella plates, namely stiffness, concentrated in a direction across the plane of the product.
Slike sjikt er tidligere blitt bygget opp ved at man på forhånd har lagt sammen oppsagede lameller eller strimler. Derved har man imidlertid stott på store vanskeligheter. Mineralullstrimlene har nemlig liten holdfasthet og er således lite egnet for håndtering. For det forste har det derfor voldt vanskeligheter å håndtere strimlene på grunn av disses manglende indre holdfasthet, og for det andre har strimlene som regel under håndteringen blitt deformert på en slik måte at det blivende, lamellerte mineralullsjikt har fått en meget ujevn overflate. Begge disse omstendigheter har bidratt til at det lamellerte produkt har fremvist store variasjoner med hensyn til tykkelse. Avhengig av den måte på hvilken man har behandlet strimlene og lagt dem ved siden av hverandre for limingen kant mot kant, har nemlig enten bare den ovre side blitt ujevn, mens undersiden er utjevnet mot underlaget eller også har begge sider blitt ujevne. Such layers have in the past been built up by previously joining terminated slats or strips. Thereby, however, great difficulties have been encountered. The mineral wool strips have little holding power and are thus not suitable for handling. Firstly, it has therefore caused difficulties in handling the strips due to their lack of internal holding strength, and secondly, the strips have usually been deformed during handling in such a way that the permanent, laminated mineral wool layer has acquired a very uneven surface. Both of these circumstances have contributed to the laminated product showing large variations in thickness. Depending on the way in which the strips have been treated and placed next to each other for the edge-to-edge gluing, either only the upper side has become uneven, while the underside has been leveled against the substrate or both sides have become uneven.
For å kunne anvende disse mineralullplater på riktig måte To be able to use these mineral wool sheets correctly
onsker man imidlertid at de er helt plane og jevne på begge sider. Foreliggende oppfinnelse vedrorer en fremgangsmåte ved hjelp av hvilken slike ikke med belegg forsynte, lamellerte mineralullplater med fullstendig jevne plansider kan fremstilles. however, you want them to be completely flat and even on both sides. The present invention relates to a method by means of which such non-coated, laminated mineral wool sheets with completely even plane sides can be produced.
Oppfinnelsen vedrorer således en fremgangsmåte for fremstilling av porose lamellplater av mineralull med pregede fiberplan samt uten overflatesjikt, idet flere mineralullsjikt stables inntil hverandre og oppdeles av snitt, som loper vinkelrett på stabelens lengderetning. The invention thus relates to a method for producing porous lamella plates of mineral wool with embossed fiber planes and without a surface layer, as several layers of mineral wool are stacked next to each other and divided by cuts, which run perpendicular to the longitudinal direction of the stack.
Ifolge oppfinnelsen stables sjiktene av mineralull med sine hovedplan vertikalt eller med en vesentlig vinkel med horisontalplanet, uten eller i det minste tilnærmelsesvis uten kompresjon, og festes med de plane, vertikale eller nesten vertikale sider mot hverandre, f.eks. ved liming, hvorpå oppdelingen finner sted vinkelrett på fiberplanenes retning. According to the invention, the layers of mineral wool are stacked with their main planes vertically or at a significant angle to the horizontal plane, without or at least approximately without compression, and fixed with the flat, vertical or almost vertical sides against each other, e.g. by gluing, after which the division takes place perpendicular to the direction of the fiber planes.
Det skal bemerkes at det er tidligere kjent, f.eks. fra det amerikanske patent 2.949.953, å stable et antall sjikt av mineralull oppå hverandre med et bindesjikt av holdfast materiale underst, samt derpå å kappe denne stabel i retning vinkelrett på sjiktningsretningen. Derved har man imidlertid fått et produkt som ikke kan anvendes for det spesielle formål som tilsiktes i foreliggende oppfinnelse. Dels har nemlig det tverrlaminerte mineralullprodukt i disse tilfeller vært komprimert i den hensikt å tilveiebringe slike rorskåler som foran nevnt. Dels har produktet i overensstemmelse hermed vært tilboyelig til å krumme seg, mens man for de formål som tilsiktes i foreliggende oppfinnelse behdver en plan formasjon. Dels er til slutt de opprinnelig foreliggende mineralullsjikt blitt ytterligere komprimert av vekten av overliggende mineralullsjikt, hvilket har fort til en ujevn tetthetsfordeling. De underste sjikt har da vært sterkt komprimert, og de overste sjikt svakere komprimert, hvilket i den derpå fremstilte tverrlaminerte mineralullplate har ytret seg slik at lamellene i den ene side av den blivende plate har hatt hoyere tetthet og storre vekt enn lamellene i den andre side av platen. Denne forskjell i egenvekt har siden ikke blitt utjevnet, eller hvis en utjevning har funnet sted har den vært meget ufullstendig. It should be noted that it is previously known, e.g. from the American patent 2,949,953, to stack a number of layers of mineral wool on top of each other with a binding layer of durable material underneath, and then to cut this stack in a direction perpendicular to the layering direction. This has, however, resulted in a product which cannot be used for the particular purpose intended in the present invention. In part, the cross-laminated mineral wool product has in these cases been compressed with the intention of providing such tillers as mentioned above. In part, the product has accordingly been prone to curving, while for the purposes intended in the present invention a flat formation is required. Partly, in the end, the originally present mineral wool layers have been further compressed by the weight of the overlying mineral wool layer, which quickly leads to an uneven density distribution. The lower layers have then been strongly compressed, and the upper layers more weakly compressed, which in the cross-laminated mineral wool board produced has manifested itself in such a way that the lamellae on one side of the resulting plate have had a higher density and greater weight than the lamellae on the other side of the disc. This difference in specific gravity has not since been equalised, or if an equalization has taken place it has been very incomplete.
Oppfinnelsen skal beskrives nærmere nedenfor under henvisning til et par på tegningen viste utforelseseksempler, men det er underforstått at oppfinnelsen ikke er begrenset til disse spesielle utforelseseksempler, idet mange forskjellige modifi-kasjoner kan forekomme innenfor oppfinnelsens ramme. Fig. 1 viser i parallellperspektiv en forste utforelsesform av oppfinnelsen, mens fig. 2 viser en modifikasjon av anordningen ifolge fig. 1. Fig. 3 viser ytterligere en modifikasjon av samme anordning. Ved den anordning som vises i fig. 1, og som anvendes for utovelse av fremgangsmåten ifolge foreliggende oppfinnelse, tilfores spundne sjikt med pregede fiberplan samt bestående av ikke komprimerbar mineralull i retningen av pilen 10 til et sta-tiv, bestående av ruller 11 og en bakgrunnsplate 12. Mineral-ulls j iktene befinner seg ved anordningen ifolge fig. 1 i vertikal stilling, slik at også fiberplanene ligger vertikalt og ved sin stivhet hindrer kompresjon av mineralullen. Mineralullen tilfores i stykker 13. Visse avvikelser fra den vertikale stilling kan forekomme, men mineralullsjiktene befinner seg i ethvert tilfelle i tilnærmelsesvis vertikal retning. Det er da av betydning å påse at forekommende skjoter mellom forskjellige stykker eller bånddeler som ligger i hverandres forlengelse, faseforskyves de forskjellige stykker eller bånddeler innbyr-des, f.eks. slik som vist ved 14. The invention will be described in more detail below with reference to a couple of exemplary embodiments shown in the drawing, but it is understood that the invention is not limited to these particular exemplary embodiments, as many different modifications may occur within the scope of the invention. Fig. 1 shows in parallel perspective a first embodiment of the invention, while fig. 2 shows a modification of the device according to fig. 1. Fig. 3 shows a further modification of the same device. In the device shown in fig. 1, and which is used for practicing the method according to the present invention, spun layers with embossed fiber planes and consisting of non-compressible mineral wool are fed in the direction of the arrow 10 to a stand, consisting of rollers 11 and a background plate 12. The mineral wool layers is located at the device according to fig. 1 in a vertical position, so that the fiber planes are also vertical and their stiffness prevents compression of the mineral wool. The mineral wool is supplied in pieces 13. Certain deviations from the vertical position may occur, but the mineral wool layers are in any case in an approximately vertical direction. It is then important to ensure that any joints between different pieces or strip parts which are in extension of each other are phase-shifted between the different pieces or strip parts, e.g. as shown at 14.
For den således foreliggende, opprinnelige, sjiktede mineralull innfores i stabelen, er dets forskjellige flatsider blitt forsynt med et limstoff, slik at de aktuelle stykker eller bånddeler limes fast flatside mot flatside mot hverandre, når de kommer inn i den renne som dannes av rullene 11 og bakgrunnsplaten 12. Eventuelt kan denne bane passere gjennom en varme-ovn, i hvilken limet bringes til å torke slik at man på denne måte får en fast sammenhengende men slett ikke eller bare ytterst ubetydelig komprimert pakke av mineralull, som har sjiktretningen i pakkens lengderetning og i en i det minste stort sett vertikal retning. For the thus existing, original, layered mineral wool to be inserted into the stack, its different flat sides have been provided with an adhesive, so that the relevant pieces or strip parts are firmly glued flat side to flat side to each other, when they enter the chute formed by the rolls 11 and the background plate 12. Optionally, this web can pass through a heating oven, in which the glue is caused to dry so that in this way you get a solidly connected but not at all or only very slightly compressed package of mineral wool, which has the layer direction in the longitudinal direction of the package and in an at least substantially vertical direction.
Ved venstre ende av den således dannede pakke, se fig. 1, er kappeanordningen vist. Denne består av et endelost sagbånd 16 som loper over et par båndhjul 17, 18. Disse er dels drei-bare om sine aksler 19, 20 samt dels forskyvbare på disse. At the left end of the package thus formed, see fig. 1, the casing device is shown. This consists of an endless saw band 16 which runs over a pair of band wheels 17, 18. These are partly rotatable about their axles 19, 20 and partly displaceable on these.
De maskinelle detaljer for tilveiebringelse av disse to be-vegelser er ikke vist på tegningen idet de er uvedkommende for oppfinnelsen. The mechanical details for providing these two movements are not shown in the drawing as they are irrelevant to the invention.
Hensikten med at mineralullsjiktene som danner pakken, ved The purpose of the mineral wool layers that form the package, at
denne utforelsesform er stilt på hoykant, er at man vil unngå kompresjon av mineralullen. Det skal påpekes at sjiktplanene vil ligge vertikalt, og at altså egenvekten av mineralullsjiktene virker i den retning, i hvilken disse overhodet ikke eller bare i ubetydelig grad er-komprimerbare. Hvis man hadde til-fort mineralullpakken med de enkelte mineralullsjikt liggende i horisontalplan over hverandre, så ville kompresjon ha fore-kommet. Derved ville man således ha fått et produkt som er dårligere anvendelig for det spesielle formål, for hvilket this embodiment is set on the high side, is that you want to avoid compression of the mineral wool. It should be pointed out that the layer planes will lie vertically, and that the specific weight of the mineral wool layers acts in the direction in which these are not compressible at all or only to a negligible extent. If you had added the mineral wool package with the individual mineral wool layers lying horizontally above each other, compression would have occurred. This would thus have resulted in a product that is less suitable for the particular purpose, for which
foreliggende produkt er tilsiktet. the present product is intended.
Man foretrekker derfor å arbeide med vertikalt eller nesten vertikalt stående plater. Det kan imidlertid under visse omstendigheter være vanskelig å få mineralullplatene til å stå One therefore prefers to work with vertical or almost vertical plates. However, in certain circumstances it can be difficult to get the mineral wool boards to stand
opprett på sine kantpartier, og ifolge den modifikasjon som vises i fig. 2, har man derfor anordnet rullebanen 11 svakt hellende mot horisontalplanet, f.eks. i en vinkel på ca. 10°. Bakgrunnsplaten 12 heller da selvsagt med samme vinkel mot vertikalplanet. upright on its edge parts, and according to the modification shown in fig. 2, the runway 11 has therefore been arranged slightly inclined towards the horizontal plane, e.g. at an angle of approx. 10°. The background plate 12 naturally then inclines at the same angle to the vertical plane.
Den nu beskrevne anordning anvendes ved utovelse av fremgangsmåten ifolge foreliggende oppfinnelse på folgende måte: Ved arbeidets begynnelse fores sagbladet 16 under bevegelse nedad, slik at man får en glatt og plan overflate 21, hvorpå sagbladet 16 igjen fores opp til en stilling helt ovenfor pakken av mineralull 13. Denne mates derpå frem et stykke, som svarer til den onskede tykkelse av den blivende, lamellerte mineralullplate. Sagbladet 16 fores så igjen ned og derpå igjen opp. Ved den sistnevnte saging er imidlertid en mineralullplate dannet som har noyaktig den tilsiktede tykkelse, og som har en helt plan overflate på hver av de to flatsider. Ved at de opprinnelig foreliggende, sjiktede mineralullmatter i pakken var limt mot hverandre, har den losskårne, lamellerte mineralullplate fått all nodvendig indre holdfasthet. Den kan derfor felles ned i retning av pilen 22, eller den kan fores ut til siden i retning av pilen 23 for å fores bort fra anordningen for å lagres eller for å transporteres til forbruksstedet. The now described device is used when practicing the method according to the present invention in the following way: At the beginning of the work, the saw blade 16 is moved downwards, so that a smooth and flat surface 21 is obtained, after which the saw blade 16 is again brought up to a position just above the pack of mineral wool 13. This is then fed forward a piece, which corresponds to the desired thickness of the remaining, laminated mineral wool sheet. The saw blade 16 is then fed down again and then up again. In the latter sawing, however, a mineral wool plate is formed which has exactly the intended thickness, and which has a completely flat surface on each of the two flat sides. Because the originally available, layered mineral wool mats in the package were glued together, the loosely cut, laminated mineral wool sheet has been given all the necessary internal strength. It can therefore be folded down in the direction of arrow 22, or it can be fed out to the side in the direction of arrow 23 to be fed away from the device to be stored or to be transported to the point of consumption.
Det er ikke nodvendig at mineralullsjiktene 13, se fig. 1 og 2, ligger med sine plan noyaktig i pakkens hoyde- eller bredderetning, representert av pilen 10. Man kan f.eks. bygge pakken opp av i såkalt fiskebensmonster anordnede mineralullplater 24, som angitt i fig. 3. Riktignok må man da tillate tap av de deler som befinner seg utenfor den prikkede linje 25. Fig. 3 viser platestabelen i retning av pilen 26, fig. 1. De i stabelen inngående mineralullplater vil på denne måte ligge i to på hverandre vinkelrette plateplan. Sjiktene danner i dette tilfelle fortrinnsvis 45° vinkel med stabelens grenseflater i hoyde-og bredderetning. It is not necessary that the mineral wool layers 13, see fig. 1 and 2, lie with their planes exactly in the height or width direction of the package, represented by the arrow 10. One can e.g. build up the package from mineral wool plates 24 arranged in a so-called herringbone pattern, as indicated in fig. 3. Admittedly, one must then allow for the loss of the parts that are outside the dotted line 25. Fig. 3 shows the plate stack in the direction of the arrow 26, fig. 1. The mineral wool boards included in the stack will in this way lie in two mutually perpendicular board planes. In this case, the layers preferably form a 45° angle with the stack's boundary surfaces in the height and width directions.
Man kan ved utovelse av oppfinnelsen ifolge ovenstående forsterke mineralullplaten ved å innfore armeringsorgan i limsjiktene mellom de forskjellige, opprinnelig foreliggende sjiktede mineralullplater. For dette formål kan man således anvende et lim som er forsynt med armerende fyllstoff, f.eks. glassfiber eller annet lignende materiale. Man kan også mellom mineralullplatene innfore et tynt, porost materialsjikt, fortrinnsvis et materialsjikt, bygget opp av vevet stoff eller orientert glassfiber. By carrying out the invention according to the above, the mineral wool board can be reinforced by introducing reinforcement in the glue layers between the different, originally existing layered mineral wool boards. For this purpose, you can thus use an adhesive that is provided with reinforcing filler, e.g. fiberglass or other similar material. A thin, porous material layer can also be inserted between the mineral wool plates, preferably a material layer made up of woven fabric or oriented glass fibre.
