Description

KI. 39be.Wedlug znanego sposobu wyrobu sztucznej gabki postepowanie polegalo na mieszaniu skoncentrowanego roztworu pochodnej celulozy z materjalami wlókni- stemi i latwo rozpuszczalnemi cialami, poczem otrzymana papka byla wprowa¬ dzana do wody, rozcienczonych kwasów, lub roztworów soli, wskutek czego ciala rozpuszczalne przechodzily do roztworu, a pochodna celulozy osadzala sie, oprzedu- jac i wiazac wlókno i dajac w rezultacie dziurkowate cialo, przypominajace wy¬ gladem gabke.Niniejszy wynalazek polega na zamianie skoncentrowanego roztworu pochodnej celulozy, splastyczniona zapomoca uprzed¬ niej obróbki roztworami alkaljów i lagod- nem ogrzewaniem kazeina lub t. p. cialami bialkowemi, zmieszanemi z materjalami wlóknistemi i latwo rozpuszczajacemi sie cialami, poczem masa obrabia* sie substan¬ cjami, przeprowadzajacemi bialko w stan nierozpuszczalny, jak naprzyklad roztwo¬ rem aldehydu mrówkowego, i po tej ope¬ racji luguje.Przyklad: Rozpuszczona w slabym lugu sodowym lub potasowym kazeine nalezy oczyscic filtrowaniem lub dekantacja. Oczyszczony roztwór miesza sie zwolna i osadza kwa¬ sem solnym, najlepiej z niewielka do¬ mieszka kwasu octowego, i wydzielony osad nastepnie przemywa. Przemyty osad traktuje sie malemi ilosciami lugu alka- ljowego lub amonjaku, dzieki czemu otrzy¬ muje sie mase plastyczna, która pozbawia sie mozliwie dokladnie wody starannem wygniataniem. Papka pozostawiona w spo¬ koju zaczyna wydzielac z siebie nadmiar uzytego lugu i, w miare wydzielania sielugu, twardniec coraz bardziej. Ten sposób obrabiania kazeiny i innych podobnych cial bialkowych jest powszechnie znany.Ze stwardnialej masy bierze sie 25 do 30 g, nagrzewa w misce od 50 do 60°, dodaje wlókien bawelnianych lub konopnych, 10$ na wage mieszaniny i nastepnie wgniata przy ogrzewaniu w ciastowata mase sze¬ sciokrotna na wage ilosc soli kuchennej, cukru, soli glauberskiej lub t. p. W czasie tej operacji pozadanem jest stopniowo i powoli obnizac temperature. Po dosta- tecznem pokryciu i oblepieniu wlókien i krysztalów lepka masa, redukuje sie temperature zupelnie, urabia papke sto¬ sownie do potrzeby w odpowiednia forme i wprowadza do roztworu aldehydu mrów¬ kowego. Zamiast rozczynu aldehydu mrów¬ kowego mozna, rozumie sie, stosowac i inne substancje, przeprowadzajace bialko w stan nierozpuszczalny, a wiec kwas garbnikowy, tanine, sole chromowe it. p.Po 12 godzinach mieszanine wyjmuje sie z kapieli i przemywaniem najpierw w zim¬ nej, nastepnie zas w cieplej wodzie usuwa latwo rozpuszczalne domieszki. Po do- kladnem przemyciu produkt jest gotowy. PLKI. 39be.According to the known method of producing an artificial sponge, the procedure consisted in mixing a concentrated solution of a cellulose derivative with fibrous materials and easily soluble bodies, and the resulting paste was then introduced into water, diluted acids or salt solutions, as a result of which the soluble bodies passed into solution , and the cellulose derivative deposited, slackening and binding the fiber, resulting in a sponge-like body with a puncture. The present invention consists of replacing a concentrated solution of a cellulose derivative, plasticized by pretreatment with alkali solutions and mild heating of casein with protein bodies, mixed with fibrous materials and easily dissolving bodies, then the mass is treated with substances that make the protein insoluble, for example with a solution of formaldehyde, and after this treatment it dissolves. weak sodium or potassium hydroxide solution others should be cleaned by filtering or decanting. The purified solution is slowly stirred and deposited with hydrochloric acid, preferably with a little acetic acid mixture, and the precipitate formed is then washed. The washed sludge is treated with small amounts of alkali or ammonia, thanks to which a plastic mass is obtained, which is completely drained of water by careful kneading. When left to rest, the pulp begins to release the excess of used slurry and, as the servant is released, it hardens more and more. This method of treating casein and other similar protein bodies is well known. From the hardened mass you take 25 to 30 g, heat in a bowl from 50 to 60 °, add cotton or hemp fibers, $ 10 per weight of the mixture and then press it into pasty when heated. six times the weight of the amount of table salt, sugar, glauber's salt or the like. During this operation it is desirable to lower the temperature gradually and slowly. After the fibers and crystals are sufficiently covered and caked, the viscous mass is completely reduced, the pulp is processed as required in a suitable form and added to the formaldehyde solution. Instead of a formaldehyde solution, it is possible to use other substances which render the protein insoluble, i.e. tannic acid, tannin, chromium salts, etc. p. After 12 hours, the mixture is taken out of the bath and washed first in cold water, then in warm water to remove easily soluble impurities. After thorough washing, the product is ready. PL
