Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania cząstek nanocelulozy o kształcie prostokątnym z odpadów z papieru gazetowego. Sposób charakteryzuje się tym, że wykonuje się kolejno następujące etapy: odpadowy, kolorowy papier gazetowy, o średniej zawartości celulozy 45 - 55% poddaje się rozdrobnieniu, rozdrobniony papier gazetowy poddaje się działaniu wodnego roztworu wodorotlenku sodu o stężeniu od 1 do 3%, przy stosunku wagowym od 1:25 do 1:35 i miesza się do momentu pęcznienia, mieszaninę ogrzewa się w zlewce w temperaturze w zakresie od 50 do 70°C, w czasie od 1 do 2h, mieszaninę przesącza się, otrzymaną pulpę poddaje się działaniu wodnego roztworu nadtlenku wodoru o stężeniu od 1,5 do 3%, przy stosunku wagowym od 1:35 do 1:45 i miesza się do momentu pęcznienia pulpy, mieszaninę ogrzewa się w zlewce, w temperaturze od 50 do 70°C, w czasie od 1 do 2h, mieszaninę przesącza się, otrzymaną pulpę poddaje się działaniu wodnego roztworu kwasu siarkowego(VI) o stężeniu od 40 do 50%, przy stosunku od 1 g:40 ml do 1 g:100 ml, mieszaninę ogrzewa się w zlewce, mieszając, w temperaturze od 50 do 60°C, w czasie od 1 do 2h, uzyskując materiał w postaci nanocząstek celulozy.The subject of the application is a method for producing rectangular-shaped nanocellulose particles from newsprint waste. The method is characterized in that the following steps are carried out in succession: waste, colored newsprint with an average cellulose content of 45 - 55% is subjected to shredding, shredded newsprint is subjected to the action of an aqueous solution of sodium hydroxide with a concentration of 1 to 3%, at a ratio weight from 1:25 to 1:35 and stirred until swelling, the mixture is heated in a beaker at a temperature ranging from 50 to 70°C for 1 to 2 h, the mixture is filtered, the obtained pulp is treated with an aqueous solution hydrogen peroxide with a concentration of 1.5 to 3%, with a weight ratio of 1:35 to 1:45 and stirred until the pulp swells, the mixture is heated in a beaker at a temperature of 50 to 70°C for 1 to 2h, the mixture is filtered, the resulting pulp is treated with an aqueous solution of sulfuric acid (VI) with a concentration of 40 to 50%, with a ratio of 1 g:40 ml to 1 g:100 ml, the mixture is heated in a beaker with stirring, at a temperature of 50 to 60°C, for 1 to 2 hours, obtaining a material in the form of cellulose nanoparticles.
