Abstract
Przedmiotem zgłoszenia jest sposób wydzielania nanowłókien celulozowych lub mieszanin nano- i mikrowłókien celulozowych z wodnej zawiesiny, który polega na tym, że do wodnej zawiesiny nanowłókien celulozowych lub mieszaniny nano- i mikrowłókien celulozowych wprowadza się w stosunku od 1 : 1 do 1 : 20 częściowo zmydlony ester nasyconego lub nienasyconego kwasu organicznego zawierającego 8 - 22 atomów węgla i niskocząsteczkowego alkoholu jednowodorotlenowego zawierającego 1 - 4 atomy węgla, o temperaturze 60 - 80°C, a następnie całość poddaje się mieszaniu, po czym powstałą mieszaninę odwadnia się na drodze suszenia znanymi metodami.The subject of the application is a method of separating cellulose nanofibers or mixtures of cellulose nano- and microfibers from an aqueous suspension, which consists in the fact that partially saponified nanofibers or mixtures of cellulose nano- and microfibers are introduced into the aqueous suspension of cellulose nanofibers. ester of a saturated or unsaturated organic acid containing 8 - 22 carbon atoms and a low molecular weight monohydric alcohol containing 1 - 4 carbon atoms at a temperature of 60 - 80 ° C, followed by stirring, and the resulting mixture is dehydrated by drying using known methods.
