Abstract

Przedmiotem zgłoszenia jest sposób poprawy właściwości wytrzymałościowych papieru, gdzie do wzmocnienia papieru używa się roztworu wodnego chitozanu i kwasu cytrynowego, a stężenie procentowe chitozanu w takim roztworze wynosi co najmniej 0,1%, zaś stężenie procentowe kwasu cytrynowego co najmniej 0,5 %, gdzie roztwór zostaje użyty w procesie wzmacniania papieru poprzez dodanie go do pulpy w proporcji co najmniej 1/2 litra roztworu na 1 kg suchego papieru według patentu PL237344 charakteryzuje się tym, że do roztworu dodaje się benzoesanu sodu w ilości 0,001% do 30% jako środka konserwującego biodegradowalną żywicę. Korzystnie roztwór koncentratu zawiera kwas cytrynowy - o stężeniu co najmniej 0,5%, chitozan o stężeniu co najmniej 0,01% oraz benzoesanem sodu o stężeniu co najmniej 0,001%. Roztwór koncentratu powinien zostać użyty w procesie wzmacniania papieru poprzez dodanie go do pulpy w proporcji co najmniej 0,5 litra roztworu na 1 kg suchego papieru.
