Description
l0 lö 20 2b 30 35 40 7893858-5 2 styrkan och porositeten förbättras samtidigt, vilket ej kan göras med enbart cellulosafibrer. Fiberprodukter enligt uppfinningen upp- visar också goda vattenavvisande egenskaper. Vid högprocentig in- blandning av mineralullsfibrer uppnås förnämliga brandhämmande egenskaper samt god termisk stabilitet. Produkten blir dessutom beständig mot mögel och mikroorganismer kan ej förankra sig på dess yta. Detta medför att den kan vara lämplig för kliniska ändamål. l0 Sat. 20 2b 30 35 40 7893858-5 2 the strength and porosity are improved at the same time, which cannot be done with cellulose fibers only. Fiber products according to the invention also shows good water-repellent properties. In the case of a high percentage of blend of mineral wool fibers is achieved excellent fire retardant properties as well as good thermal stability. The product will also be resistant to mold and microorganisms can not anchor on its surface. This means that it may be suitable for clinical purposes.
-Den nya produkten ger också god hâllfasthet mot förslitning och mot slag- och dragpâkänning. Vid användning av glasfibrer och_vattenglas, som är kända för sina dielektriska egenskaper, erhåller produkten även en elektrisk isoleringsförmåga, som uppfyller högt ställda krav.-The new product also provides good resistance to wear and tear impact and tensile stress. When using fiberglass and water glass, known for their dielectric properties, the product is obtained also an electrical insulation capacity, which meets high requirements.
Krympnings- och sammandragningsförmágan hos produkten blir obetydlig.The shrinkage and contraction ability of the product becomes insignificant.
Fiberprodukter enligt uppfinnningen framställes utgående från en fibersuspension av bearbetade cellulosafibrer. Till denna sus- pension sättes vattenglasbindrmedel. Mineralullsfihrer likaledes i suspensionsfas tillsättes slutligen till cellulpsafibersuspensionen, varefter den sålunda kompletterade suspensionen eller mälden efter ytterligare behandling, exempelvis efter tillsättande av lim, färg- ämnen, fyllnads- och förtjockningsmedel torkas och pressas för erhållande av slutprodukten. Hed fördel kan exempelvis glasfibrer med en diameter av ca 7 p - standardglasfibrer för byggisolering - användas i samband med det nya förfarandet.Fiber products according to the invention are prepared on the basis of a fiber suspension of processed cellulosic fibers. To this sus- pension is set water glass binder. Mineral wool fibers likewise in suspension phase is finally added to the cellulose fiber suspension, after which the suspension or stock thus supplemented further treatment, for example after the addition of glue, substances, fillers and thickeners are dried and pressed for obtaining the final product. For example, fiberglass can benefit with a diameter of about 7 p - standard fiberglass for building insulation - be used in connection with the new procedure.
Det har även visat sig fullt möjligt att med gott resultat för inblandning utnyttja kantspill och kasserade produkter från mineralullstillverkningen.It has also proved quite possible that with good results for mixing use edge waste and discarded products from mineral wool production.
Vattenglasbindemedlet kan bestå av föreningar av kiselsyra och natrium eller kalium med tillsats av karbamid och/eiler propylen- glykol. Goda reslutat har exempelvis uppnåtts med natriumsiiikat med ett molförhällande mellan natriumoxid och kiseldioxid av 1:3, 4-4,l. Dessutom kan vattenglasbindemedlet vara modifierat med kon- ventionellt organiskt eller oorganiskt bindemedel.The water glass binder may consist of compounds of silicic acid and sodium or potassium with the addition of urea and / or propylene glycol. Good results have been achieved, for example, with sodium silicate with a molar ratio of sodium oxide to silica of 1: 3, 4-4, l. In addition, the water glass binder may be modified with conventional organic or inorganic binder.
Den för framställningsförfarandet av produkten använda cellu- losamassan, som kan vara blekt eller oblekt, har iordningsställts -i förväg, så att fibrernas specifika yta ökats och en god anliggning: yta erhålles mellan fibrerna i arkets formningsögonblick. Detta ástadkommes pá konventionellt sätt genom mekanisk påverkan, så kallad malning, som utföres i pulpers, jordankvarnar och raffinörer.The cellulose used for the production process of the product the loose material, which may be bleached or unbleached, has been prepared -in advance, so that the specific surface area of the fibers is increased and a good bearing: surface is obtained between the fibers at the moment of formation of the sheet. This achieved in a conventional manner by mechanical action, so called grinding, which is carried out in pulps, earth mills and refiners.
Vid denna bearbetning förkortas också cellulosafibrernas längd något samtidigt som fiberknippena uppspaltas. Såsom cellulosamassa an- vändes exempelvis björk-, tall- eller granmassa. Vid det nya för- l5 20 So 40 7803858-5 3 farandet uppslammas denna massa i ett första vattenkar och i ett andra vattenkar uppslammas mineralullsfibrer från t ex mineralulls- skivor, -mattor, -flockar eller dylikt. Även kasserade produkter kan med fördel, såsom ovan nämnts, användas. Vattenglasbindemedlet tillsättes till det första karet med cellulosamassa och därefter blandas innehållet i de båda karen. Den hopblandade kopositionen, mälden, kan sedan behandlas pà känt sätt, varvid den exempelvis blandas med lim, färgämnen, fyllnads- och förtjockningsmedel för att sedan torkas och pressas. Élàllâåll s I en pulper blandas under 5 minuter glasfibrer och vatten för erhållande av en suspension eller s k slurry. inblandad mängd glas- fiber utgör härvid 10 vikt-ï. Som jämförelse kan nämnas att en vanlig cellulosafiberslurry innehåller vanligtvis 3 - 3,5 vikt-i cellulosa, vilket alltså ger en relativt hög vattenhalt, då produk- ten föres in på en vira för att avvattnas. En massa, innehållande en viss mängd glasfibrer, torkar betydligt snabbare i pappersmaski- nen än en ren cellulosafibermassa, vilket av ekonomiska skäl är fördelaktigt, då tillverkningshastigheten därvid kan ökas.During this processing, the length of the cellulose fibers is also shortened somewhat at the same time as the fiber bundles are split. As cellulosic pulp used for example, birch, pine or spruce pulp was turned. At the new l5 20 So 40 7803858-5 3 This mass is slurried in a first water tank and in one other water tanks, mineral wool fibers are slurried from e.g. boards, rugs, flocks or the like. Even discarded products can advantageously, as mentioned above, be used. The water glass binder is added to the first tub of pulp and then mix the contents of the two vessels. The mixed coposition, the stock, can then be treated in a known manner, whereby, for example mixed with adhesives, dyes, fillers and thickeners to then dried and pressed. Élàllâåll s In a pulper, mix glass fibers and water for 5 minutes obtaining a suspension or so-called slurry. amount of glass involved fiber here constitutes 10% by weight. For comparison, it can be mentioned that a regular cellulose fiber slurry usually contains 3 - 3.5 wt-i cellulose, which thus gives a relatively high water content, as the is introduced into a wire to be dewatered. A lot, containing a certain amount of glass fiber, dries much faster in paper than a pure cellulose fiber pulp, which for economic reasons is advantageous, as the production speed can thereby be increased.
Efter blandningen införes glasfiberslurryn i ett mäldkar.After mixing, the glass fiber slurry is introduced into a milking parlor.
I ett annnat mäldkar iordningsställes en 3ï-ig cellulosafiber- slurry av blekt björkmassa. Till denna sättes 5 3 bindemedel av natrium-vattenglas, räknat pâ den totala mängden glasfiber- och cellulosafiberslurry, med ratio 3,4 samt innehållande karbamid och propylenglykol. Vattenglasbindemedlets funktion är dels att minska fibrernas vätbarhet, dvs att göra dem mera vattenavvisande, dels att minska porradien, dvs att utfylla porerna i arket, så att por- diametern minskar och vätskeinträngning försvåras.In another milk cell, a 3 μg cellulose fiber is prepared. blurry of bleached birch pulp. To this is added 5 3 binders sodium-water glass, calculated on the total amount of fiberglass and cellulose fiber slurry, with a ratio of 3,4 and containing urea and propylene glycol. The function of the water glass binder is partly to reduce the wettability of the fibers, ie to make them more water-repellent, partly to reduce the pore radius, ie to fill the pores in the sheet, so that the diameter decreases and fluid penetration becomes more difficult.
Glasfiberslurryn tillsättes och blandas med cellulosafiber- vattenglas-slurryn. Andelen i kompositionen ingående glasfibrer upp- går till l0 vikt-1 av den totala mängden. Blandningen av cellulosa- fibrer, glasfibrer och vattenglasbindemedel är alkalisk, dvs pH- värdet uppgår till 9,0 - 9,5. Som jämförelse kan nämnas att en 'vanlig cellulosaiibermassa i detta skede vanligtvis har ett pH-värde. som uppgår till 4,5. Inget vätmedel eller alun tillsättes till slurryn och ingen höjning av temperaturen förekommer såsom vid kon- ventionell tillverkning.The fiberglass slurry is added and mixed with the cellulosic fiber. water glass slurry. The proportion of glass fibers included in the composition is goes to 10 weight-1 of the total amount. The mixture of cellulose fibers, glass fibers and water glass binder are alkaline, ie the pH the value amounts to 9.0 - 9.5. For comparison, it can be mentioned that a Ordinary cellulosic pulp at this stage usually has a pH value. which amounts to 4.5. No wetting agent or alum is added slurry and no increase in temperature occurs as in the case of conventional manufacturing.
Den erhållna slurryblandningen passerar därefter en konkvarn och föres pä konventionellt sätt via en pappersmaskins inloppslada ut pà en vira. l0 15 20 25 30 35 40 7803858-5 4 En fiberprodukt framställd på ovan beskrivet sätt har fördelar framför allt genom mycket god rivhâllfasthet samt goda tryckegen- skaper exempelvis för flerfärgstryck beroende pä en god dimensionell stabilitet mellan fibrerna i produkten. Kvaliteten kan även vara mycket lämplig som t ex emballage genom sin goda formföränderlighet.The resulting slurry mixture then passes through a grinder and is fed in a conventional manner via the inlet tray of a paper machine ut pà en vira. l0 15 20 25 30 35 40 7803858-5 4 A fiber product prepared in the manner described above has advantages above all through very good tear resistance and good compressive creates for example for multicolor printing depending on a good dimensional stability between the fibers in the product. The quality can also be very suitable as, for example, packaging due to its good variability in shape.
Exempel 2.Example 2.
Detta prov utfördes på exakt samma sätt som provet i exempel l men med 30 % inblandning av mineralullsfibrer, lO % vattenglasbinde- medel och 60 % cellulosafibrer.This test was performed in exactly the same way as the test in Example 1 but with 30% admixture of mineral wool fibers, 10% water glass binder agents and 60% cellulose fibers.
Genom den ökade inblandningen av mineralull skedde torkningen snabbare än i det första exemplet. g Papperet erhöll goda dielektriska egenskaper, god hàllfasthet mot förslitning samt mot drag- och slagpäkänning. Krympnings- och sammandragningsförmâgan var obetydlig. i I Exempel 3.Due to the increased admixture of mineral wool, the drying took place faster than in the first example. g The paper obtained good dielectric properties, good strength against wear and against tensile and impact stress. Shrinkage and the ability to contract was insignificant. in In Example 3.
Provet utfördes pâ samma sätt som de tvâ tidigare endast med ändrade mängdförhållanden mellan komponenterna. I detta fallet blandades 90 % mineralullsfibrer med 5 % vattenglasbindemedel och 5 % cellulosafibrer. e Det framställda papperet uppvisade goda egenskaper med avseende på obrännbarhet och oantändlighet samt god termisk stabilitet och det var dessutom resistent mot mögel.The test was performed in the same way as the two previous ones only changed quantity ratios between the components. In this case 90% mineral wool fibers were mixed with 5% water glass binder and 5% cellulose fibers. e The paper produced showed good properties with respect to on non-combustibility and flammability as well as good thermal stability and that was also resistant to mold.
Exempel 4.Example 4.
Vid detta fjärde prov, som också utfördes på samma sätt som de övriga, ingick 50 % mineralullsfibrer, 10 % vattenglasbindemedel, 5 % melaminharts och 35 % cellulosafibrer.At this fourth test, which was also performed in the same way as them others, included 50% mineral wool fibers, 10% water glass binder, 5% melamine resin and 35% cellulose fibers.
De specifika egenskaperna hos denna kvalitet var goda vikegen- skaper och en mycket slät yta.The specific properties of this quality were good yield properties. creates and a very smooth surface.
Som framgår av exemplen kan man genom att variera mängden mineralullsfibrer, cellulosafibrer och vattenglasbindemedel uppnå papperskvaliteter med olika egenskaper. Sålunda kan man genom hög- procentig inblandning av mineralullsfibrer - försök har gjorts med inblandning upp till 95 vikt-% - uppnå papperskvaliteter med t ex för- nämliga brandhämmande egenskaper.As can be seen from the examples, you can by varying the amount mineral wool fibers, cellulose fibers and water glass binders achieve paper grades with different properties. Thus, by percentage mixture of mineral wool fibers - experiments have been made with mixture up to 95% by weight - achieve paper qualities with e.g. namely fire retardant properties.
Försök har också gjorts med upp till 30 vikt-% vattenglasbinde- medel med gott resultat.Experiments have also been made with up to 30% by weight of water glass binder. funds with good results.
Iäde exempel, som ovan angivits, har olika typer av pappers- kavaliteter framställts. Uppfinningen är emellertid inte begränsad till fiberprodukter endast i form av relativt tunna ark såsom papp, kartong och dylikt utan kan mycket väl omfatta en produkt med upp 5 vaosess-s tiil några centimeters tjockïek i form av en filt.Examples, as stated above, have different types of paper cavalities produced. However, the invention is not limited to fibrous products only in the form of relatively thin sheets such as cardboard, carton and the like but may very well include a product with up 5 vaosess-s to a few centimeters thick in the form of a blanket.
I de angivna exempïen har karbamid och propyienglykoi till- förts i bindemedlet men nämnda ämnen kan naturligtvis likaväl tiHför-as suspensionen separat.In the examples given, urea and propylene glycol have been added. carried in the binder but the said substances can of course as well The suspension is fed separately.
