Description
Wynalazek dotyczy sposobu wyrobu materjalu zastepujacego garbniki, który moze byc uzyty dla otrzymania zdatnej do uzytku skóry zarówno sam, jak i z do¬ tychczas uzywanemi roslinnemi ekstrak¬ tami garbniczemi, i to naogólbez zmiany dotychczasowych sposobów pracy.Materjalem wyjsciowym jest smola, a to zarówno smola wegla kamiennego jak i brunatnego, dalej smola z torfu i wszystkich rodzajów drzewa.Wazne dla niniejszego sposobu sklad¬ niki wydziela sie ze smoly w robocie wstepnej zapompca wody albo alka- ljów oraz obojetnych i zasadowych soli. Traktowanie wstepne ostatnio wy- mienionemi materjalami, w porównaniu z traktowaniem jedynie woda, ma te zalete, ze w ten sposób lepiej mozna wykorzystac materjal podstawowy. Do plynu wydzielonego ze smoly dodaje sie siarczanu glinowego i siarczanu miedzi. Zamiast siarczanu glinu mozna uzyc takze aluny: potasowy, chromowy, amonowy. Tak otrzymana ciecz uzywa sie do garbowania skóry. Jako pozosta¬ losc otrzymuje sie ciagliwa smolista mase, z której, przez nowe traktowanie wyzej wymienionemi materjalami, mozna otrzymac ponownie materjal zastepujacy garbnik. Zamiast pózniejszego dopiero traktowania siarczanem glinii i miedzi, mozna te zwiazki wprowadzac w trakto¬ waniu wstepnem.Otrzymuje sie w ten sposób wytwór, który, w razie potrzeby, moze byc uzyty do garbowania skóry. Rezultat jednak tego postepowania jest znacznie gorszy, niz przy dodawaniu omawianych cial po traktowaniu wstepnem. Nastepnie moznauzyskac dzialanie garbujace z pomoca tylko jednego z wymienionych siarcza¬ nów. Uzycie jednak jedynie siarczanu miedzi, daje znacznie slabsze dzialanie garbujace i skóre mniej pelna, niz przy dodawaniu siarczanu glinu, lub dajacych sie uzyc zamiast niego siarczanów albo alunów. Dodatek siarczanów glinu i t. p., przeciwnie, poprawia ciecz, i to tak, ze wykazuje ona wlasciwosci podobne do wyciagów z garbników roslinnych. Przy pominieciu znowu siarczanu miedzi otrzy¬ muj e sie najczesciej skóre o niepozada¬ nej ciemno-szarej barwie.Sposób mozna przeprowadzac na zimno lub w wyzszej temperaturze, wply¬ wajacej na przyspieszenie dzialania.Przyklad.W stu czesciach wagowych wody roz¬ puszcza sie 20—25 czesci wagowych siar¬ czanu sodu lub innego z alkaljów, obo¬ jetnej lub podwójnej soli. Do tego roz¬ tworu dodaje sie 50 czesci wagowych smoly, np. smoly z buczyny, i miesza sie mase mieszadlem przez czas dluzszy.Nastepnie, przy trwalem mieszaniu, do¬ daje sie 8 — 10 czesci wagowych siar¬ czanu glinu, 6—7 czesci wagowych alunu poczem wylacza sie mieszadlo, dodaje si§ Vs — 1 czesci wagowych siarczanu miedzi, i wreszcie puszcza sie znowu w ruch urzadzenie mieszadlowe. Ciecz, wydzielona powyzszym sposobem, mozna uzywac do garbowania wprost, lub za¬ gescic przez odparowanie. PLThe invention relates to a method of producing a material that replaces tannins, which can be used to obtain a leather that can be used, both by itself and with the vegetable tannin extracts used so far, and this generally without changing the current working methods. The starting material is tar, and this is both tar hard coal and brown coal, hereinafter peat tar and all kinds of wood. The constituents important for the present process are separated from the tar in the preliminary work of a pump of water or alkalis and inert and alkaline salts. Pretreatment with the recently mentioned materials, compared to treatment only with water, has the advantage that the base material can be used better in this way. Aluminum sulphate and copper sulphate are added to the liquid separated from the tar. Instead of aluminum sulphate, you can also use alumas: potassium, chromium, ammonium. The liquid thus obtained is used for tanning leather. As a residue, a gritty tar mass is obtained, from which, by a new treatment with the above-mentioned materials, it is possible to obtain again a material replacing a tannin. Instead of a subsequent treatment with clay and copper sulphate, these compounds can be introduced in a pretreatment, thus obtaining a product which, if necessary, can be used for the tanning of leather. However, the result of this procedure is much worse than when adding the bodies in question after the pretreatment. Then, a tanning action can be obtained with only one of the sulfates mentioned. However, the use of copper sulphate only gives a much weaker tanning effect and the skin is less full than with the addition of aluminum sulphate or alternatively possible sulphates or aluns. The addition of aluminum sulphates, etc., on the contrary, improves the liquid, so that it exhibits properties similar to vegetable tannins. If you omit copper sulphate again, you usually get a dark gray skin that is undesirable. The method can be carried out cold or at a higher temperature, which will accelerate the action. Example: One hundred parts by weight of water dissolve 20 - 25 parts by weight of sodium or other alkali sulphate, neutral or double salt. 50 parts by weight of tar, e.g. beech tar, are added to this solution, and the mass is mixed with a mixer for a longer time. Then, with continued stirring, 8-10 parts by weight of aluminum sulphate are added, 6-7 parts by weight of the alum, then the agitator is switched off, Vs - 1 part by weight of copper sulphate is added, and finally the agitator is started again. The liquid separated by the above process may be used for direct tanning or kneaded by evaporation. PL
