Description

Soda techniczna, stosowana powszech¬ nie dotychczas do traktowania materjalów wlókienniczych w apreturach i farbiar- niach oraz w papierniach do czyszczenia szmat, ma te wade, ze dzialanie jej polega wylacznie na czyszczeniu, a nie na bieleniu i praniu traktowanych materjalów.Dla uzupelnienia jej dzialania w tym kierunku nalezalo dodawac do niej pew¬ nych tluszczów, np. oleiny, co nietylko komplikowalo manipulacje, lecz równiez znacznie zwiekszalo koszty produkcji.Sposób, stanowiacy przedmiot niniej¬ szego wynalazku, usuwa powyzsze wady.Stosownie do wynalazku sode przygoto¬ wuje sie w bardzo prosty sposób, a miano¬ wicie mieszanine sody z mala iloscia siar¬ ki rozpuszcza sie w wodzie i do roztworu dodaje sie fodsiarczyn sodowy, weglan po¬ tasowy i mydlo oleinowe. W ten sposób wy¬ tworzony produkt po wysuszeniu miele sie, poc^em jest gotowy do uzytku.Ponizej jest podany przyklad wykona¬ nia przedmiotu wynalazku.Przyklad. 500 kg sody technicznej (Na2 CO J miesza sie z 3 kg siarki (SJ. Miesza¬ nina zostaje nastepnie rozpuszczona w 300 kg wody. Do otrzymanego roztworu dodaje sie 18 kg podsiarczynu sodu (Na2 S2 O.. + 5 H2OJ, 3 kg weglanu potasowego (K2 CO.) oraz 3 kg mydla oleinowego.Otrzymany produkt schnie w ciagu 6-u godz w temperaturze 15°C. Po uplywie te¬ go czasu zestala sie, poczem zostaje zmie¬ lony i w tym stanie jest gotowy do u- zytku. PL PL PLTechnical soda, commonly used so far for treating textile materials in finishing shops and dyeing plants, as well as in paper mills for cleaning rags, has the disadvantage that its action consists only in cleaning, and not in bleaching and washing the treated materials. To supplement its action in this direction, certain fats, e.g. olein, had to be added to it, which not only complicated the manipulation but also significantly increased the production costs. The method, which is the subject of the present invention, eliminates the above disadvantages. According to the invention, soda is prepared in a very simple way, namely, a mixture of soda with a small amount of sulfur is dissolved in water, and sodium phosphate, potassium carbonate and soap are added to the solution. The product thus obtained is ground after drying and is then ready for use. Below is an example of the invention. Example: 500 kg of technical soda (Na2CO2) is mixed with 3 kg of sulfur (SJ). The mixture is then dissolved in 300 kg of water. To the resulting solution are added 18 kg of sodium hydrosulfite (Na2SO2) + 5 H2O2, 3 kg of potassium carbonate (K2CO2) and 3 kg of oleic soap. The resulting product dries for 6 hours at 15°C. After this time, it solidifies, is then ground and is ready for use. PL PL PL
