Description

Sposób wytwarzania wyrobów gipsowych, zawierajacych wlókna Przedmiotem wynalazku jest sposób wytwarzania wyrobów gipsowych zawierajacych wlókna, na przyklad plyt i innych elementów konstrukcyjnych, zwlaszcza ognioodpornych wyrobów gipsowych za¬ wierajacych jako skladniki wzmacniajace i ognio¬ odporne wlókna szklane i/lub wlókna z welny zuz¬ lowej.W znanych sposobach wytwarzania wyrobów gipsowych zawierajacych wlókna szklane i/lub wlókna z welny zuzlowej, trudno jest uzyskac rów¬ nomierne rozlozenie sie wlókien w gipsie, gdyz wlókna te maja tendencje do splatywania sie i zbrylania. Totez nie osiaga sie zadanego, korzyst¬ nego efektu, to jest wymaganej wytrzymalosci me¬ chanicznej i ognioodpornosci, który moznaby osiag¬ nac przy rozlozeniu równomiernym wlókien w mie¬ szaninie gipsowej uzytej do odlewania, a zatem i w odlewach. Znane jest ciecie wlókien na tak krótkie odcinki, ze nie moga sie one zbrylac, jed¬ nak wytworzony takim sposobem wyrób nie ma zadawalajacej calkowicie wytrzymalosci mecha¬ nicznej.Wedlug znanego sposobu wytwarzania wyrobów gipsowych wlókna szklane tnie sie i laczy ze soba za pomoca spoiwa rozpuszczalnego w wrodzie.Wytworzone w ten sposób wiazki wlókien wpro¬ wadza sie do mokrego gipsu i miesza sie z nim w celu uzyskania równomiernego rozlozenia wló¬ kien w gotowym odlewie gipsowym. Sposób ten ma te niedogodnosc, ze mieszanie wlókien z mie- 15 20 25 30 szanina gipsowa jest czasochlonne. Ponadto spoiwo moze stanowic niepozadany skladnik w gotowych wyrobach gipsowych.Celem i zadaniem wynalazku jest opracowanie sposobu wytwarzania wyrobów gipsowych w któ¬ rych nie beda wystepowac wady znanych sposobów i który rozwiazuje problem zbrylania sie wlókien w sposób skuteczniejszy niz to zostalo osiagniete dotychczas.Zadanie postawione przed wynalazkiem zostalo osiagniete przez to, ze wlókna szklane i/lub wlókna welny zuzlowej grepluje sie, a podczas greplowa¬ nia dodaje sie proszek gipsowy w celu wytworze¬ nia suchej mieszaniny, która nastepnie miesza sie z woda by otrzymac mokra mieszanine stosowana do odlewania wyrobów, przeprowadzanego w zna¬ ny sposób.Jesli proszku gipsowego nie doda sie do wlókien przed zakonczeniem greplowania, wlókna latwo zbrylaja sie uniemozliwiajac uzyskanie równomier¬ nego rozlozenia wlókien w mieszaninie.Szczególnie korzystne jest stosowanie wlókien szklanych z wlóknami z welny zuzlowej, gdyz welna zuzlowa powoduje lepsza ognioodpornosc wyrobu a wlókna szklane polepszaja jego wytrzy¬ malosc mechaniczna. Stosujac te rodzaje wlókien w odpowiednich ilosciach uzyskuje sie wyroby o bardzo dobrych wlasciwosciach ognioodpornych oraz o duzej wytrzymalosci na zginanie i rozcia¬ ganie. Pod wplywem wysokiej temperatury, na 8071080710 przyklad ponad 600°C szklo topi sie i wiaze sie z welna zuzlowa tak, ze wyrób posiada duza wy¬ trzymalosc nawet w tego rodzaju warunkach.Mieszanie suchej mieszaniny gipsu i wlókien z woda dokonuje sie przez wprowadzanie suchej mieszaniny do naczynia z woda w takiej ilosci, ze woda i mieszanina gipsu z wlóknami osiagaja ra¬ zem ten sam poziom w naczyniu. Otrzymana mase wodna odlewa sie do form.Odpowiednim spoiwem nadajacym sie do dodania do wody lub masy wodnej jest octan poliwinyiu, jednak moga byc stosowane równiez inne rodzaje spoiw i inne dodatki.Urzadzenie do stosowania sposobu wedlug wy¬ nalazku jest przedstawione na zalaczonym rysunku, na którym przedstawiono urzadzenie 1 i 2 dozu¬ jace wlókna szklane i wlókna welny zuzlowej na przenosnik tasmowy 3, który dostarcza wlókna do bebna greplujacego 5, do którego jest dostarczany równiez z dozownika 4 proszek gipsowy. Miesza¬ nina wlókien i gipsu jest podawana z bebna 5 na przenosnik tasmowy 6, który dostarcza ja do na¬ czynia 7. Do naczynia 7 dostarczane sa odpowied¬ nie ilosci wody, spoiwa i ewentualnie innych do¬ datków, przed dodaniem mieszaniny gipsu z wlók¬ nami szklanymi i wlóknami welny zuzlowej. Z na¬ czynia 7 mokra masa podawana jest do, nie przed¬ stawionych na rysunku, form, w których odlewane sa gotowe wyroby. Jesli jest to potrzebne przepro¬ wadza sie dalsza obróbke wyrobów, na przyklad suszenie, prasowanie, pokrywanie i podobne.Wynalazek jest blizej wyjasniony nastepujacym przykladem stosowania sposobu. 15 20 25 Przyklad I. Mieszanine 0,2 kg welny zuzlo¬ wej i 0,1 kg wlókien szklanych zgreplowano i pod¬ czas greplowania zmieszano z 0,9 kg proszku gipso¬ wego. Otrzymana sucha mieszanine wprowadzono do 1 1 wody zawierajacej niewielka ilosc dodatków.Mokra mase uzyto do odlewania plyt w formach wykonanych z tektury.Sposób wedlug wynalazku nadaje sie do zastoso¬ wania przy wytwarzaniu róznych wyrobów gipso¬ wych, zwlaszcza w meblarstwie, budownictwie okretowym i budownictwie, gdzie potrzebne sa ma¬ terialy ognioodporne na przyklad do wyrobu krze¬ sel, stolów, plyt, elementów, drzwi, kanalów i po¬ dobnych.Wyroby maja duza wytrzymalosc mechaniczna, nie sa palne i nadaja sie do mocowania za pomoca wkretów i gwozdzi. PL PLMethod for the production of gypsum products containing fibers The subject of the invention is a method for the production of gypsum products containing fibers, for example boards and other structural elements, in particular fire-resistant gypsum products containing glass fibers and / or fibers of fiberglass as reinforcing components and / or In the known processes for the production of gypsum products containing glass fibers and / or knotty wool fibers, it is difficult to obtain a uniform distribution of the fibers in the gypsum, as these fibers have a tendency to become entangled and lumpy. Therefore, the desired advantageous effect, that is, the required mechanical strength and fire resistance, that could be achieved by uniformly distributing the fibers in the gypsum mixture used for casting, and therefore in castings, is not achieved. It is known to cut the fibers into such short lengths that they cannot clump together, however, the product produced in this way does not have a fully satisfactory mechanical strength. According to the known method of producing gypsum products, glass fibers are cut and joined together with a soluble binder. The fiber bundles produced in this way are introduced into the wet plaster and mixed with it in order to obtain an even distribution of the fibers in the finished plaster cast. This method has the disadvantage that mixing the fibers with the plaster mix is time-consuming. Moreover, the binder may be an undesirable component in the finished gypsum products. The object and purpose of the invention is to develop a method for the production of gypsum products which will not suffer from the disadvantages of known methods and which solves the problem of fiber agglomeration more effectively than has been achieved so far. The invention has been achieved by the fact that the glass fibers and / or the fibers of the saggy wool grind, and during the grouting, gypsum powder is added to form a dry mixture which is then mixed with water to obtain a wet mixture used for casting articles. performed in a known manner. If the gypsum powder is not added to the fibers before the completion of the grooving, the fibers easily agglomerate, making it impossible to obtain an even distribution of the fibers in the mixture. Particularly advantageous is the use of glass fibers with fibers made of sullen wool, as the wool causes better fire resistance of the product and wear glass stones improve its mechanical strength. By using these types of fibers in appropriate quantities, products with very good fire-resistant properties and high bending and tensile strength are obtained. Under the influence of high temperature, at 8071080710, for example over 600 ° C, the glass melts and binds to knotty wool, so that the product has a high strength even under such conditions. Mixing the dry gypsum-fiber mixture with water is done by introducing a dry mixture into a vessel of water in such an amount that the water and the mixture of gypsum with fibers together reach the same level in the vessel. The resulting aqueous mass is poured into molds. Polyvinyl acetate is a suitable binder suitable for addition to water or water mass, but other types of binders and other additives may also be used. The apparatus for carrying out the method according to the invention is shown in the attached drawing, which shows a device 1 and 2 for dispensing glass fibers and knotted wool fibers onto the conveyor belt 3, which supplies the fibers to the grooving drum 5, to which gypsum powder is also supplied from the dispenser 4. The mixture of fibers and gypsum is fed from the drum 5 to the conveyor belt 6, which delivers it to vessel 7. Appropriate amounts of water, binder and possibly other additives are supplied to vessel 7, before adding the gypsum-fiber mixture. With glass and snotty wool. From vessel 7, the wet mass is fed into molds, not shown, in which the finished products are cast. If necessary, further processing of the products is carried out, for example drying, pressing, coating and the like. The invention is explained in more detail by the following example of the application of the method. EXAMPLE 1 A mixture of 0.2 kg of knotty wool and 0.1 kg of glass fibers was gummed and mixed with 0.9 kg of gypsum powder during the greasing process. The obtained dry mixture was introduced into 1 liter of water containing a small amount of additives. The wet mass was used for casting boards in forms made of cardboard. The method according to the invention is suitable for use in the production of various gypsum products, especially in furniture, shipbuilding and construction. where fire-resistant materials are needed, for example, for the manufacture of chairs, tables, boards, components, doors, channels and the like. The products have high mechanical strength, are non-flammable and can be fastened with screws and nails. PL PL
