Opublikowano dnia 1 kwietnia 1958 r. £ lim? ^ POLSKIEJ RZECZYPOSPOLITEJ LUDOWEJ OPIS PATENTOWY Nr 40766 KI, 8 i, 5 Stanislaw Karczewski Warszawa, Polska Sposób wytwarzania srodka do prania zawierajacego szklo wodne Patent trwa od dnia 17 sierpnia 1957 r« Dla celów pralniczych uzywane jest szklo wodne w stanie plynnym oraz oddzielnie per- hydrol. Dystrybucja powyzszych skladników w stanie plynnym nastrecza duzo trudnosci, ze wzgledu na koniecznosc stosowania szklanego opakowania, obszernych magazynów do sklado¬ wania i srodków transportowych o znacznym tonazu. Poza tym w okresie zimowym szklo wod¬ ne zamarza w czasie transportu, jak równiez w nieogrzanych magazynach.Trudnosci powyzsze sprawiaja, ze zapotrzebo¬ wanie rynku detalicznego w szklo wodne jest pokrywane zaledwie w bardzo nieznacznym pro¬ cencie.Zagadnienie to rozwiazuje wprowadzenie do handlu suchej substancji w postaci kostek lub proszku skladajacej sie ze szkla wodnego i per- hydrolu, która moze byc uzupelniona mydlem lub innymi srodkami, stosowanymi przy praniu bielizny.Suche szklo wodne otrzymuje sie z normal¬ nego technicznego roztworu szkla wodnego za¬ wierajacego Si02 : Na20 = 2,6 — 3,0 przez wzbo¬ gacenie krzemionka do stosunku Si02 : Na20 = = 3,2 — 3,4. Wzbogacony krzemionka roztwór odparowywuje sie przy temperaturze nie prze¬ kraczajacej 750 C. Tak zageszczony roztwór nie moze zawierac wiecej niz 25°/o wody. Szklo wod¬ ne po ostudzeniu posiada postac ciagliwej ga¬ larety, do której, przy nieustannym mieszaniu, wprowadza sie potrzebna ilosc perhydrolu np. ^/o wagi szkla wodnego. Wymieszane szklo wodne z perhydrolem pozostawia sie celem prze- reagowania (ustabilizowania) przez 12 godzin a po uplywie tego czasu masa bardzo powoli pecznieje, powiekszajac swa objetosc kilkakrot¬ nie i krzepnie. Uzyskany produkt dosusza sie w temperaturze nie przekraczajacej 300 C w ciagu okolo 3 godzin, otrzymujac lekka, plywajaca po wodzie mase, bardzo latwo sie rozpuszczajaca i wydzielajaca aktywny perhydrol, który w cza¬ sie procesu wytwarzania tego srodka zostal za¬ sklepiony w drobinkach szkla wodnego. PLPublished April 1, 1958. £ lim? ^ POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 40766 KI, 8 i, 5 Stanislaw Karczewski Warsaw, Poland Manufacturing method for a washing agent containing water glass The patent is valid from August 17, 1957. «For laundry purposes, water glass is used in a liquid state and separately per- hydrol. The distribution of the above ingredients in a liquid state is very difficult due to the necessity to use a glass container, large warehouses for storage and means of transport with a significant tonnage. In addition, in winter, the water glass freezes during transport, as well as in unheated warehouses. The above difficulties mean that the demand of the retail market for water glass is met only at a very slight cost. This problem is solved by the introduction to dry trade. a substance in the form of cubes or a powder consisting of water glass and perhydrol, which may be supplemented with soap or other washing agents. Dry water glass is obtained from a normal technical water glass solution containing SiO 2: Na 2 O = 2.6-3.0 by increasing the silica to the ratio SiO2: Na2O = = 3.2-3.4. The enriched silica solution is evaporated at a temperature not exceeding 750 ° C. The solution thus concentrated must not contain more than 25% water. After cooling, the water glass is in the form of a tough jelly to which, with constant stirring, the required amount of perhydrol, for example about the weight of water glass, is added. The mixed water glass with perhydrol is left to react (stabilize) for 12 hours and after that time the mass swells very slowly, increasing its volume several times and solidifies. The obtained product is dried at a temperature not exceeding 300 ° C for about 3 hours, obtaining a light, floating mass that dissolves very easily and emits active perhydrol, which during the production process of this agent was vaulted in water glass particles .
