Description
Celem niniejszego wynalazku jest prze¬ dluzenie ezasu trwania oraz ochrona den kotlowych, rur plomiennych i t. p. czesci metalowych, wystawionych na * dzialanie ognia przed zniszczeniem, wynikajacem wskutek polaczonego dzialania wysokiej temperatury i powietrza, a polegajacem na tworzeniu sie na powierzchni blachy war¬ stwy tlenków latwo luszczacych sie i odpa¬ dajacych. Proces luszczenia sie blachy, tworzenia sie zendry i t. p. tlenków w krót¬ kim stosunkowo czasie doprowadza do zu¬ pelnego zniszczenia materjalu i powoduje koniecznosc czestej naprawy lub calkowi¬ tej wymiany blach. Wynalazek niniejszy, majac na celu ochrone blachy przed wyzej wymienionem dzialaniem ognia i powietrza, daje moznosc oszczedzenia samego mate¬ rjalu, jak równiez znacznych kosztów na¬ prawy lub wymiany przepalonych czesci.Cel ten wedlug niniejszego wynalazku osiagnieto przez pokrywanie blach, wysta¬ wionych na niszczace dzialanie ognia i po¬ wietrza, masa dostatecznie ogniotrwala, scisle przylegajaca do blach cienka war¬ stewka, nie wplywajaca zbyt ujemnie na przewodnictwo cieplne, a uniemozliwiajaca bezposredni dostep powietrza do rozgrza¬ nych czesci blach. i^asa odpowiadajaca powyzszemu celo¬ wi jest mieszanina glinokrzemianów sodo¬ wa- lub potasowo-wapniowych o zmiennym skfadzie, dostosowanym do danego przy¬ padku. Mase naklada sie w sposób bardzo prosty, mianowicie zarabia sie ja z woda i przy pomocy pendzla powleka sie dana po-wierzchnie. I tak dno kotla destylacyjne¬ go, pokryte warstewka o skladzie 20% gli¬ ny, 25% piasku, 30% wapna, 25% sody kau¬ stycznej wytrzymalo 125 tur zamiast nor¬ malnych okolo 30-tu. PLThe object of the present invention is to extend the life and protect the boiler bottoms, flame tubes and other metal parts exposed to fire from damage due to the combined action of high temperature and air by the formation of an oxide layer on the sheet surface. easy to peel off and fall off. The process of sheet peeling, scale formation and the like of oxides in a relatively short time leads to the complete destruction of the material and necessitates frequent repair or complete replacement of the sheets. The present invention, in order to protect the sheet against the above-mentioned action of fire and air, enables the material itself to be saved, as well as the significant cost of repairing or replacing burnt parts. According to the present invention, destructive action of fire and air, the mass is fireproof enough, tightly adhering to the sheets, a thin layer that does not affect the thermal conductivity too much, and prevents direct access of air to the heated parts of the sheets. An equivalent corresponding to the above purpose is a mixture of sodium or potassium-calcium aluminosilicates with a variable composition, adapted to the particular case. The mass is applied in a very simple way, namely, it is made with water and the surface is coated with a pen. Thus, the bottom of the distillation kettle, covered with a 20% clay, 25% sand, 30% lime, 25% caustic layer, withstood 125 turns instead of the normal 30%. PL
