Description
Fremgangsmåte for fremstilling av Method of manufacture of
fiberholdige gipsprodukter. fibrous gypsum products.
Denne oppfinnelse angår en fremgangsmåte for fremstilling av fiberholdige produkter, særlig plater og andre konstruksjonselementer, på gipsbasis. Spesielt angår den fremstilling av brannhemmende gipsprodukter inneholdende glass-og/eller stenullfibre som armerende og brannhemmende bestanddeler. This invention relates to a method for the production of fibre-containing products, particularly boards and other construction elements, on a plaster basis. In particular, it concerns the production of fire-retardant plaster products containing glass and/or stone wool fibers as reinforcing and fire-retardant components.
Ved fremstilling av gipsprodukter inneholdende In the manufacture of gypsum products containing
glass- og/eller stenullfibre er det et problem å få fordelt fibrene i gipsmassen da de har en tendens til å filtre seg sammen og danne klumper eller baller. Man oppnår derved ikke den tilsiktede gunstige virkning, nemlig mekanisk styrke og brannsikkerhet, som er avhengig av at fibrene er jevnt fordelt glass and/or stone wool fibres, it is a problem to distribute the fibers in the plaster mass as they tend to tangle together and form lumps or balls. This does not achieve the intended beneficial effect, namely mechanical strength and fire safety, which depends on the fibers being evenly distributed
i gipsmassen som anvendes til støpning og derved i de støpte produkter. Det er mulig å kutte opp fibrene til så korte lengder at de ikke kan filtre seg sammen, men de derav fremstilte produkter har ikke helt tilfredsstillende mekanisk styrke. in the gypsum mass used for casting and thereby in the cast products. It is possible to cut the fibers into such short lengths that they cannot tangle together, but the products produced from them do not have completely satisfactory mechanical strength.
Et forsøk på å løse dette problem er beskrevet i tysk patent nr. 934.395 som angår fremstilling av gipsprodukter inneholdende glassfibre som fyllstoff. I henhold til patentet kuttes glassfibrene opp og bindes sammen med et vannoppløselig bindemiddel. Disse sammenbundne fiberbunter innføres i og blandes med den fortrinnsvis våte gipsmasse for å oppnå en jevn fordeling av fibrene i den ferdigstøpte gipsgjenstand. Fremgangsmåten ifølge patentet er tungvint, og særlig sammenblandingen av fibrene med gipsmassen tar lang tide Videre får man en til-setning av bindemiddel som kan være uønsket i det ferdige gips-produkt. An attempt to solve this problem is described in German patent no. 934,395 which concerns the production of plaster products containing glass fibers as filler. According to the patent, the glass fibers are cut up and bound together with a water-soluble binder. These interconnected bundles of fibers are introduced into and mixed with the preferably wet plaster mass in order to achieve an even distribution of the fibers in the finished plaster object. The method according to the patent is cumbersome, and in particular the mixing of the fibers with the plaster mass takes a long time.Furthermore, you get an addition of binder which may be undesirable in the finished plaster product.
Formålet med foreliggende oppfinnelse er å tilveie-bringe en fremgangsmåte som løser de ovenfor nevnte sammen-filtringsproblemer på en bedre og mer effektiv måte enn tid-ligere. I henhold til oppfinnelsen tilveiebringes således en fremgangsmåte for fremstilling av gipsprodukter, særlig plater og andre konstruksjonselementer, inneholdende glass- og/eller stenullfibre som armerende og brannhemmende bestanddeler. Fremgangsmåten karakteriseres ved at glass- og/eller stenull kardes, og under kardingen tilsettes gipspulver for å gi en tørr masse som blandes med vann, eventuelt inneholdende lim og/eller andre tilsetningsstoffer, for å gi en våt masse som anvendes til støpning av de ønskede produkter på i og for eeg kjent måte. The purpose of the present invention is to provide a method which solves the above-mentioned entanglement problems in a better and more efficient way than before. According to the invention, a method is thus provided for the production of plaster products, in particular sheets and other structural elements, containing glass and/or stone wool fibers as reinforcing and fire-retardant components. The method is characterized by glass and/or stone wool being carded, and during the carding gypsum powder is added to give a dry mass which is mixed with water, possibly containing glue and/or other additives, to give a wet mass which is used for casting the desired products in a manner known to and for eeg.
Hvis man venter med å tilsette gipspulveret til efter at kardingen er ferdig, vil fibrene ha lett for å klumpe eeg sammen uten at det oppnåes en jevn blanding av fibre og gipspulver. If one waits to add the gypsum powder until after the carding is finished, the fibers will tend to clump together without an even mixture of fibers and gypsum powder being achieved.
Det er funnet særlig hensiktsmessig å anvende både stenull og glassull ved fremgangsmåten, eftersom stenullen gir produktet den beste brannhemmende virkning, mens glasBullen gir det den beste mekaniske styrke. Ved å anvende begge disse fibertyper i passende mengder kan man få produkter med meget gode brannhemmende egenskaper samtidig som det kan oppnåes It has been found particularly appropriate to use both rock wool and glass wool in the process, since rock wool gives the product the best fire-retardant effect, while glasBullen gives it the best mechanical strength. By using both of these fiber types in suitable quantities, products with very good fire-retardant properties can be obtained at the same time
stor bøye-, strekk- og tverrfasthet. Ved høy varmepåvirknihg, for eksempel over ca. 600°C, vil glasset smelte og binde aten-ullen slik at produktet også vil være meget sterkt selv under great bending, tensile and transverse strength. In case of high heat exposure, for example over approx. 600°C, the glass will melt and bind the aten wool so that the product will also be very strong even under
slike forhold. such conditions.
Sammenblanding av den tørre gips/fiber-blanding med Mixing of the dry plaster/fibre mixture with
vann utføres hensiktsmessig ved at den tørre blanding føres ned i et kar med vann i slik mengde at vannet og gips/fiber-blanding-en blir stående i samme høyde i karet. Den vandige masse man da får, er velegnet til støpning. water is suitably carried out by placing the dry mixture into a vessel with water in such an amount that the water and the gypsum/fibre mixture remain at the same height in the vessel. The watery mass you then get is suitable for casting.
Et egnet lim som kan settes til vannet eller den vandige masse, er polyvinylacetat, men også andre limtyper og andre tilsetningsstoffer kan anvendes. A suitable glue that can be added to the water or the aqueous mass is polyvinyl acetate, but other types of glue and other additives can also be used.
Utstyr for utførelse av fremgangsmåten er skjematisk vist på figuren hvor 1 og 2 er vekter/doseringsutstyr for sten-og glassull, 3 er matebånd for sten- og glassull, 4 er vekt/ doseringsutstyr for gips, 5 er kardevalse som karder ut ullen og blir påført gips, 6 er matebånd for oppkardet ull med gips, og 7 er våtblander. Denne er på forhånd hensiktsmessig tilsatt de riktige mengder vann, lim og eventuelle andre tilsetningsstoffer før tørrblandingen av sten- og glassull og gips blir tilført. Pra våtblanderen 7 føres den våte masse til former (ikke vist) hvor det ferdige produkt støpes. Eventuelt fore-taes en efterbehandling, for eksempel tørring, pressing, be-legning osv. Equipment for carrying out the procedure is schematically shown in the figure, where 1 and 2 are scales/dosing equipment for stone and glass wool, 3 is feeding belt for stone and glass wool, 4 is weight/dosing equipment for plaster, 5 is a carding roller that cardes out the wool and becomes applied plaster, 6 is a feeding belt for carded wool with plaster, and 7 is a wet mixer. The correct amounts of water, glue and any other additives have been suitably added to this in advance before the dry mixture of stone wool and glass wool and plaster is added. From the wet mixer 7, the wet mass is fed into molds (not shown) where the finished product is cast. Optionally, a finishing treatment is carried out, for example drying, pressing, coating, etc.
Oppfinnelsen skal illustreres nærmere ved hjelp av følgende eksempel. The invention shall be illustrated in more detail by means of the following example.
Eksempel Example

Den derved erholdte tørre blanding ble ført ned i 11 vann inneholdende mindre mengder tilsetningsstoffer. Den våte masse ble anvendt til støpning av plater i former av kartong. The dry mixture thus obtained was introduced into water containing smaller amounts of additives. The wet mass was used for casting plates in cardboard forms.
Fremgangsmåten i henhold til oppfinnelsen kan anvendes for fremstilling av en rekke forskjellige gipsprodukter, spesielt for møbel-, skips- og bygningsindustrien, hvor man ønsker brannhemmende materialer, for eksempel til stoler, bord, plater, elementer, dører, rør, osv. Produktene har stor mekanisk styrke, de er ikke brennbare og de holder godt på skruer og spikere. The method according to the invention can be used for the production of a number of different plaster products, especially for the furniture, ship and building industry, where fire-retardant materials are desired, for example for chairs, tables, plates, elements, doors, pipes, etc. The products have great mechanical strength, they are not flammable and they hold screws and nails well.
