Description

Wiadomem jest, ze smola drzewna jasna ceni sie znacznie wyzej od ciemnej, ale ¦dotychczas nie udawalo sie ciemfrej smoly przerabiac 'na jasna.Wynalazca zauwazyl, ze ciemna barwa smoly drzewnej pochodzi z zawieszonych w niej czastek stalych, przewaznie z cza¬ stek rozpylonego wegla (sadzy). Dla rozja¬ snienia przeto smoly wystarczy usuniecie tych nadajacych jej ciemna barwe czastek.Usuwanie to wynalazca proponuje wyko¬ nywac na drodze mechanicznej w dowolny sposób, np. zapomoca wirówek.Jezeli smola jest zbyt gesta i z tego po¬ wodu poddawanie jej traktowaniu na wi¬ rówkach nastrecza trudnosci, to trudnosci te moga byc usuniete przez podgrzanie smoly albo rozpuszczenie w odpowiednim rozpuszczalniku.Powyzszy proces przedstawia jeszcze i te zalete, ze moga byc przy pomocy niego usuniete ze smoly niepozadane alejki, jak równiez i szkodliwa woda, dzieki czemu moze byc otrzymywana smola o pozadanej gestosci. PLIt is known that light wood tar is valued much higher than dark tar, but until now it has not been possible to turn dark tar into light tar. (soot). To lighten the tar, therefore, it is enough to remove those particles that give it a dark color. The inventor proposes to remove it mechanically in any way, e.g. with centrifuges. If the tar is too thick and for this reason it should be treated with troughs pose difficulties, these difficulties can be removed by heating the tar or dissolving it in a suitable solvent. The above process also shows the advantage that it can remove unwanted alleys from the tar, as well as harmful water, thanks to which it can be obtained tar of the desired density. PL

Claims

Patent claims. 1. A method of cleaning (lightening) wood tar, characterized by the fact that the wood tar is mechanically removed, eg by means of centrifuges, by removing the carbon particles suspended therein.

2. The method according to claim The method of claim 1, wherein the tar is heated or dissolved in any solvent prior to the mechanical treatment.

3. The method according to p. 1 and 2, characterized by the fact that the centrifuge process is carried out in such a way that the tar separates volatile oils and water, thus obtaining tar of any density. Józef Adler. Deputy: M. Brokman, Patent attorney Druk L. Boguslawski, Warsaw. PL
