Description
463 502 2 10 15 20 25 30 35 BESKRIVNING AV UPPFINNINGEN Syftet med föreliggande uppfinning är att åstad- komma ett metallfiberarmerat packningsmaterial som inte uppvisar de hittills kända materialens nackdelar samt ett förfarande för dess framställning. Syftet har uppnåtts med en metallfiberarmerad board innefattande åtminstone fibrer av cellulosa och metall, varvid cellulosafibrerna företrädesvis är avsedda att binda samman eventuella tillsatsmaterial i boarden och metallfibrerna är avsedda att bilda ett sammanhållet metallfiberskikt som ger den önskade hållfastheten åt boardmaterialet t ex vid använd- ning i packningar för hög temperatur. 463 502 2 10 15 20 25 30 35 DESCRIPTION OF THE INVENTION The object of the present invention is to provide come a metal fiber reinforced gasket material that does not exhibits the disadvantages of the hitherto known materials as well as a procedure for its preparation. The purpose has been achieved with a metal fiber reinforced board comprising at least cellulose and metal fibers, the cellulosic fibers preferably are intended to bind together any additives in the board and the metal fibers are intended to form a cohesive metal fiber layer which provides it the desired strength of the board material, e.g. in high temperature gaskets.
Företrädesvis innefattar packningsmaterialet åt- minstone ett metallfiberskikt som är beläget mellan ett första cellulosafiberskikt och ett andra cellulosafiber- skikt, varvid åtminstone ett cellulosafiberskikt innehål- ler ett värmebeständigt material såsom kaolin, kyanit el- ler vermiculit. Packningsmaterialet enligt uppfinningen kännetecknas av att cellulosafiberskikten innehåller oblekta cellulosafibrer, att fibrerna i cellulosafiber- skikten har en längd mindre än 1 mm och att fibrerna i metallfiberskiktet utgörs av kolstål med en kolhalt på 0,08-0,12 % och har en fibertjocklek på 8-80 um. Med för- del innehåller det första cellulosafiberskiktet och/eller det andra cellulosafiberskiktet lignin. Vidare kan me- tallfiberskiktet vara helt eller delvis penetrerat av material från det första och andra cellulosafiberskiktet och eventuellt bindemedel som anbringats mellan cellulo- safiberskikten. Härigenom åstadkommes en motståndskraftig sammanläggning av cellulosafiberskikt och metallfiber- skikt.Preferably, the packing material comprises at least one metal fiber layer located between one first cellulosic fibrous layer and a second cellulosic fibrous layer, at least one cellulosic fibrous layer containing a heat-resistant material such as kaolin, kyanite or ler vermiculite. The packing material according to the invention characterized in that the cellulosic fibrous layers contain unbleached cellulosic fibers, that the fibers in cellulosic fibers the layers have a length less than 1 mm and that the fibers in the metal fiber layer consists of carbon steel with a carbon content of 0.08-0.12% and has a fiber thickness of 8-80 μm. With pre- part contains the first cellulosic fibrous layer and / or the second cellulosic fibrous layer lignin. Furthermore, the pine fiber layer be fully or partially penetrated by materials from the first and second cellulosic fibrous layers and any binder applied between the cellulose the safiber layers. This provides a resilient aggregation of cellulose fiber layers and metal fiber layer.
De i åtminstone ett cellulosafiberskikt ingående värmebeständiga materialen såsom kaolin, kyanit eller vermiculit ökar boardens förmåga att tåla höga tempera- turer. Genom att fibrerna i cellulosafiberskikten har en längd som är mindre än 1 mm ges boarden en tillfredsstäl- lande gastäthet. 10 15 20 25 30 35 3 463 502 Förfarandet enligt uppfinningen kännetecknas av att ark innehållande cellulosafibrer åstadkommes genom avvattning av en mäld av cellulosafibrer och värmebestän- diga tillsatsmaterial, att cellulosafiberarken förses med ett bindemedel på de sidor som är avsedda att befinna sig mot varandra i en färdig packning och att åtminstone en matta av stålfibrer anbringas mellan åtminstone två cel- lulosafiberark och att cellulosafiberarken och metallfi- bermattan pressas samman. Sammanpressningen av cellulosa- fiberarken och metallfibermattan sker företrädesvis vid förhöjd temperatur.Those in at least one cellulosic fibrous layer heat-resistant materials such as kaolin, kyanite or vermiculite increases the board's ability to withstand high temperatures. tours. Because the fibers in the cellulosic fiber layers have a length of less than 1 mm, the board is given a satisfactory land gas density. 10 15 20 25 30 35 3 463 502 The method according to the invention is characterized by that sheets containing cellulosic fibers are produced by dewatering of a stock of cellulose fibers and heat resistance additive materials, that the cellulosic fiber sheets are provided with an adhesive on the sides intended to be located against each other in a finished package and that at least one carpet of steel fibers is placed between at least two cells cellulose fiber sheets and that the cellulose fiber sheets and the berm rug is compressed. The compression of cellulose the fibreboard and the metal fiber mat are preferably made at elevated temperature.
Genom uppfinningen är det således möjligt att utnyttja kolstålfibrer i en board som framställts från en mäld av cellulosafibrer med hög vattenhalt. I de hittills kända tillämpningarna med inblandning av stålfibrer i board och liknande material har man varit hänvisad till rostfritt stål eller metaller som inte påverkas av vatt- net i mälden från vilken boarden framställes. Genom att hålla isär framställningen av cellulosafiberskikten från en mäld i vatten från framställningen av metallfiberskik- ten har det möjliggjorts att använda fibrer av kolstål.Through the invention it is thus possible that utilize carbon steel fibers in a board made from a stock of high water content cellulose fibers. In the so far known applications with the incorporation of steel fibers in board and similar materials have been referred to stainless steel or metals not affected by water net in the stock from which the board is made. By keep apart the production of cellulosic fibrous layers from a stock in water from the production of metal fiber layers It has been possible to use carbon steel fibers.
Genom att kolstålfibrerna anbringas i form av en matta i boarden kan fiberlängden göras mycket stor och därmed ge goda armeringsegenskaper. För att öka den termiska och mekaniska stabiliteten hos boarden kan det även vara en fördel att blanda stålfibrer med aluminiumfibrer. Det är även tänkbart att använda enbart aluminiumfibrer i vissa tillämpningar.By applying the carbon steel fibers in the form of a mat in the board, the fiber length can be made very large and thus give good reinforcement properties. To increase the thermal and mechanical stability of the board it can also be a advantage of mixing steel fibers with aluminum fibers. It is also conceivable to use only aluminum fibers in some applications.
Som exempel på boardens värmetålighet vid in- blandning av olika tillsatsmaterial, uppnår man en tem- peraturhärdighet på 1300°C genom inblandning av kya- nit, 800°C genom inblandning av vermiculit, vilket skall jämföras med värmetåligheten hos harts på upp till 500°C och cellulosa något över 100°C.As an example of the board's heat resistance at mixture of different additives, a temperature is achieved temperature hardness of 1300 ° C by mixing kya- nit, 800 ° C by mixing vermiculite, which shall be compared with the heat resistance of resins of up to 500 ° C and cellulose slightly above 100 ° C.
I exempel på packningsmaterial där särskilt goda resultat uppnåtts uppvisar boarden enligt uppfinningen 1-4 skikt av stålfiber med kolhalten 0,08-0,12 % och en 465 502 4 10 15 20 25 30 35 fibertjocklek på 8-18 um. Stålfiberskikten omges på båda sidor av skikt innehållande oblekta cellulosafibrer och eventuellt lignin, som vanligen tvättas bort ur den koka- de massan vid cellulosatillverkning, men som i detta fall med fördel får kvarstanna då det i detta fall visat sig förbättra packningsmaterialets egenskaper. Vidare inne- håller skikten mjukgörare i form av latexmaterial samt harts från cellulosatillverkning som bindemedel. Pack- ningsmaterialet ges en total tjocklek på 0,5-6 mm och har visat sig tåla ett tryck på 65 bar vid 265°C. Vid pack- ningsmaterialets uppvärmning, som normalt sker under drift på den plats där det används, sker en vulkanisering av latexmaterialet genom närvaron av svavel i det övriga packningsmaterialet.In examples of packing materials where particularly good results obtained show the board according to the invention 1-4 layers of steel fiber with a carbon content of 0.08-0.12% and one 465 502 4 10 15 20 25 30 35 fiber thickness of 8-18 μm. The steel fiber layers are surrounded on both sides of layers containing unbleached cellulosic fibers and possibly lignin, which is usually washed away from the cocaine the mass in cellulose production, but as in this case with advantage may remain as it turned out in this case improve the properties of the packing material. Further content holds the layers plasticizer in the form of latex material as well resin from cellulose production as a binder. Pack- The material is given a total thickness of 0.5-6 mm and has proved to withstand a pressure of 65 bar at 265 ° C. When packing the heating material, which normally takes place during operation at the place where it is used, a vulcanization takes place of the latex material through the presence of sulfur in the rest the packing material.
