Abstract
Przedmiotem wynalazku jest sposób wytwarzania włókien mikrocelulozy z domieszką węglanu wapnia z odpadów nieekologicznego białego papieru biurowego. Sposób charakteryzuje się tym, że wykonuje się kolejno następujące etapy: materiał w postaci odpadów nieekologicznego białego papieru biurowego o średniej zawartości celulozy od 55% do 85% rozdrabnia się, rozdrobniony materiał poddaje się działaniu wodnego roztworu wodorotlenku sodu o stężeniu o stężeniu od 2% do 4%, przy stosunku wagowym od 1:20 do 1:30 i miesza się do momentu pęcznienia, mieszaninę ogrzewa się w temperaturze w zakresie od 60°C do 80°C, w czasie powyżej 0,5 h, mieszaninę przesącza się, po czym przepłukuje się wodą destylowaną do momentu uzyskania pH równego od 5 do 6, mieszaninę suszy się do stałej masy, do suchej masy dodaje się wodę uzyskując roztwór w stosunku masowym od 1:4 do 1:5, roztwór z materiałem mieli się młynie kulowym z wykorzystaniem nieniszczących się kul w cyklach, w których temperatura mielonego materiału nie przekracza 50°C, zaś między cyklami mielenia stosuje się przerwę w czasie której materiał się ochładza do temperatury nie niższej niż 23°C i dolewa się wody w ilości od 6,5% do 25% masowych, cykle mielenia powtarza się do uzyskania włókien mikrocelulozy.
