Description

Znane sa sposoby wytwarzania materja- lów budowlano-izolacyjnych z welny drzew¬ nej, slomy, trzciny lub podobnych orga¬ nicznych materjalów wlóknistych z doda- niem np. gliny, maczki azbestowej lub po¬ dobnych materjalów sproszkowanych oraz odpowiedniego spoiwa.Wynalazek niniejszy polega na stoso¬ waniu do wytwarzania izolacyjnego mate¬ rjalu budowlanego tych samych skladni¬ ków, lecz zmieszanych w odpowiednim stosunku, a mianowicie: trzy czesci wagowe organicznych materjalów wlóknistych mie¬ sza sie z okolo 5 do 7.5 czesciami wagowe- mi sproszkowanego surowca, a otrzymana mieszaninie zarabia sie 5 do 7.5 czesciami wajgowemi plynnego szkla wodnego o ste¬ zeniu od 36° do 38° Be. Materjaleni najbar¬ dziej odpowiednim do wytwarzania izola¬ cyjnego materjalu budowlanego sposobem wedlug wynalazku niniejszego sa obok wel¬ ny drzewnej, slomy lub trzciny — odpad¬ ki trzciny cukrowej, lyko, suszone trawy lub podobne materjaly. Jako sproszkowane su¬ rowce stosuje sie piasek i podobne mate¬ rjaly.Mase, otrzymana w ten sposób, umie¬ szcza sie w blaszanych formach dziurkowa-nych I poddaje ja cisnieniu w zamknietej formie przy jednoczesnem ogrzewaniu masy.W celu otrzymania ostrych i mocnych krawedzi ksztaltek, mase wtlacza sie sil¬ niej przy sciankach form.Na rysunku przedstawiono urzadzenie do wyrobu ksztaltek z masy, wytwarzanej w sposób, opisany powyzej. Fig. 1 przed¬ stawia widok zgóry urzadzenia do wyrobu ksztaltek, fig. 2 — przekrój czesciowy tego urzadzenia, a fig. 3 — przekrój formy po ukonczeniu prasowania. Stlaczanie ksztal¬ tek uskutecznia sie pomiedzy dziurkowana spodnia blacha a i taka sama blacha górna, czyli pokrywa b. Miedzy temi plytami bla- szanemi sa umieszczone podluzne listwy blaszane c i nieco krótsze równiez blaszane listwy d o przekroju w ksztalcie litery U z dziurkowanym mostkiem. Klamry / zacho¬ dza pod spodnie oraz ponad górne blachy i przytrzymuja oraz lacza ze soba po¬ szczególne czesci formy. Po wypelnieniu formy wytworzona masa, naklada sie na forme rame pomocnicza g, przez która wpro¬ wadza sie do formy górna blache b, zapo- moca której stlacza sie mase. Stlaczanie przerywa sie w chwili, gdy blacha b oprze sie na listwach c. Dalsze stlaczanie masy wykonywa sie, po nalozeniu klamer / na spodnia i górna blache b i a, zapomoca na¬ cisku, wywieranego na cztery boczne listwy c i d, w celu wzmocnienia krawedzi ksztalt¬ ki. Nastepnie forme wraz z wytloczona ksztaltka doprowadza sie zapomoca prze¬ nosnika bebnowego / do pieca, w celu pod¬ dania ksztaltki dzialaniu ciepla. Przez techniczne ogrzewanie rozumie sie proces bardziej lub mniej ceramiczny, przy któ¬ rym gazy ogrzewajace przeprowadza sie przez materjal, przyczem roztwór szkla wodnego tworzy czesciowo zwiazki chemicz¬ ne z krzemianem glinu surowców, PL PLThere are known methods for producing building and insulating materials from wood wool, straw, reed or similar organic fibrous materials with the addition of e.g. clay, asbestos flour or similar powdered materials and a suitable binder. The present invention consists in using the same components for producing building insulating material, but mixed in a suitable ratio, namely: three parts by weight of organic fibrous materials are mixed with about 5 to 7.5 parts by weight of powdered raw material, and the obtained mixture is mixed with 5 to 7.5 parts by weight of liquid water glass with a concentration of 36° to 38°. Be. The most suitable materials for producing insulating building materials according to the method of this invention are, in addition to wood wool, straw, or reed, sugarcane waste, bast, dried grasses, or similar materials. Sand and similar materials are used as powdered raw materials. The mass obtained in this way is placed in perforated sheet metal molds and subjected to pressure in a closed mold while heating the mass. In order to obtain sharp and strong edges on the shapes, the mass is pressed more firmly against the walls of the molds. The drawing shows a device for producing shapes from the mass produced in the manner described above. Fig. 1 shows a top view of the device for producing shapes, Fig. 2 shows a partial cross-section of this device, and Fig. 3 shows a cross-section of the mold after pressing is completed. The shapes are pressed between a perforated bottom sheet a and a similar top sheet, i.e., the cover b. Between these sheet metal plates are placed longitudinal sheet metal strips c and slightly shorter sheet metal strips d, also with a U-shaped cross-section and a perforated bridge. Clamps / go under and over the bottom and top sheets and hold and connect the individual mold parts. After the mold is filled with the produced mass, an auxiliary frame g is placed on the mold, through which the top sheet metal b is introduced into the mold, through which the mass is pressed. Pressing is stopped when sheet b rests on strips c. Further pressing of the mass is performed after clamping the bottom and top sheets b and a by applying pressure to the four side strips c and d to strengthen the edges of the shape. The mold, along with the extruded shape, is then fed via a drum conveyor into the furnace to expose the shape to heat. Technical heating is understood as a more or less ceramic process in which heating gases are passed through the material, whereby the water glass solution partially forms chemical compounds with the aluminum silicate of the raw materials.
