Description

467 244 2 genom torlcning av vattenglas. Denna torkning görs bäst som spraytorkning. 467 244 2 by drying water glass. This drying is best done as a spray drying.

Vill man göra en fiberprodukt med hög vattentålighet, kan man som hårdare för silikatlimmet använda olika föreningar av 2-värda metaller. Särskilt lämplig som hårdare har 'magnesiumoxid visat sig vara.If you want to make a berry product with high water resistance, you can do it harder the silicate adhesive use various compounds of 2-valent metals. Particularly suitable as magnesium oxide has been found to be harder.

Följande exempel visar ett par utföringsformer av uppfinningen utan att begränsa densamma: i Exempel 1 Granflis defibreras i en skivdefibrör. De varma tràfibrerna avskiljs från ångan medelst en cyklon, från vilken de med transportskruv och transportband förs till en fräs, som dispergerar dem i en luftström in i en difiusor. Där blåses spraytorkat natriumsilikatpulver med ratio 3,3 in i fiber-luftströmmen och blandas med fibrerna i förhållandet 10 - 25 delar silikatpulver på 100 delar torrtänkt fiber. F iberns fukthalt vid inblåsningen i diffusorn är 50 %.The following examples illustrate a few embodiments of the invention without limitation the same: i Example 1 Gran fl is defibrated in a disk defibrillator. The hot wood is separated from the steam by means of a cyclone, from which those with conveyor screw and conveyor belt are conveyed to one milling cutter, which disperses them in an air stream into a di or usor. Spray-dried is blown there sodium silicate powder with ratio 3.3 into the fiber-air stream and mixed with the fibers in the ratio 10 - 25 parts silicate powder to 100 parts dry-dried fiber. F iberns moisture content when blown into the diffuser is 50%.

Fiber-pulver-luftströmmen går från diffitsorn in i formeraren och bildar en kaka, som sedan överförs till en varmpress, där den ges sin slutliga form och torkas.The fiber-powder air stream passes from the diffuser into the former and forms a cake, which is then transferred to a hot press, where it is given its final shape and dried.

Exempel 2 Träfibrer från en defïbrör blåses ned i en blandare, där de blandas med natriumsilikatpulver (ratio 3,3) och magnesiumoxid i förhållandet 10 delar silikatpulver och 8 delar magnesiumoxidpulver på 100 delar torrtänkt fiber.Example 2 Wood fibers from a defibrillator pipe are blown into a mixer, where they are mixed with sodium silicate powder (ratio 3.3) and magnesium oxide in a ratio of 10 parts silicate powder and 8 parts magnesium oxide powder on 100 parts dry-dried fiber.

Fiberns fukthalt vid inblåsningen i diflitsornär 50 %.The moisture content of the fiber when blown into the diet is close to 50%.

Blandningen förs med transportslauv till en ejektor, som dispergerar den i luft och blåser in den i diffusorn på en formeringsmaskin, i vilken den formas, varmpressas, härdas och torkas till önskade fiberkroppar. Kakan kan även torkas utan att komprimeras och får då lämplig densitet för att kunna användas som isoleringsmaterial.The mixture is passed with a transport hose to an ejector, which disperses it in air and blows it into the diffuser of a forming machine in which it is formed, hot pressed, cured and dried to desired fiber bodies. The cake can also be dried without being compressed and then given the appropriate density to be used as insulation material.

Som antytts i ingressen till ansökningen kan även andra fibrer än direktframställda träfibrer användas till framställning av produkter enligt uppfinningen. Exempel på andra, lämpliga fibrer är pappers- och pappersreturfibrer, bomulls-, lin- och hampflbrer, syntetiska plymerfïbrer, mineralfibrer med flera.As indicated in the preamble to the application, fibers other than directly produced can also be used wood fibers are used in the manufacture of products according to the invention. Examples of other, suitable fibers are paper and paper recycled fibers, cotton, linen and hemp fibers, synthetic polymer fibers, mineral fibers and more.

Förutom limpulver kan man tillsammans med dem även tillsätta pulvrtserade fyllmedel såsom kaolin, krita, dolomit m fl för att nå speciella egenskaper t ex bättre branduthållighet, lägre kostnad, m m.In addition to glue powder, you can also add powdered ones together with them fillers such as kaolin, chalk, dolomite etc. to achieve special properties e.g. better fire resistance, lower cost, etc.

Claims (7)

3 467 244 Patentkrav 1 i Sätt att tillverka fiberkroppar ~ skivor, profiler, paneler, isoleringsmattor, emballagematerial med mera - enligt den så kallade torra metoden, kännetecknat av att det erforderliga limmet tillförs de fuktiga fibrerna i form av ett pulver av alkalivattenglas, som under den fortsatta processen löses i närvarande vatten och övergår i plastisk eller flytande form och limmar samman fibrerna, varpå limmet torkar och hårdnar till ett fast bindemedel. 3,467,244 Claim 1 in Methods of making carrier bodies - boards, profiles, panels, insulation mats, packaging materials, etc. - according to the so-called dry method, characterized in that the required adhesive is applied to the moist fibers in the form of an alkali water glass powder, as under the continued process is dissolved in the present water and turns into a plastic or liquid form and glues the joints together, after which the glue dries and hardens to a solid binder. 2 Sätt enligt krav 1 kännetecknat av att vattenglaspulvret innehåller vatten, bundet till alkalisilikatet som kristallvatten eller liknande. A method according to claim 1, characterized in that the water glass powder contains water, bound to the alkali silicate as crystal water or the like. 3 , Sätt enligt krav 1 och 2 kännetecknat av att vattenglaspulvret utgörs av spraytorkat vattenglas. 3. A method according to claims 1 and 2, characterized in that the water glass powder consists of spray-dried water glass. 4 Sätt enligt krav 1 och 2 kännetecknat av att man även tillsätter en hårdare, som under varmpressningen omvandlar alkalisilikatet till vattenolösliga silikater och därmed gör fiberkroppen vattenfastare. A method according to claims 1 and 2, characterized in that a harder is also added, which during the hot pressing converts the alkali silicate into water-insoluble silicates and thus makes the bare body more water-resistant. 5 Sätt enligt krav 1, 2 och 4 kånnetecknat av att man som härdare använder olika föreningar av 2-värda metaller.
