The invention further discloses a method for making paper from
waste paper. The method includes the following steps of 1, pulping, wherein the
waste paper is put in a 60 DEG
C constant-temperature water bath tank to be heated, the concentration is adjusted to range from 4% to 6%, and the
waste paper is added into a stirrer to be pulped for 40 min; 2,
deinking, wherein
deinking is carried out through a floatation washing method, wherein a
deinking agent is a mixture of an
acrylonitrile-butadiene-
styrene copolymer,
potassium oleate and octaphenyl polyoxyethyiene at the ratio of 3:2:1; 3,
impurity removing, wherein
printing ink particles in paper pulp are removed; 4, decoloring, wherein the paper pulp is bleached through
white rot fungi,
printing ink fine particles in the paper pulp are removed again, the PH value is controlled to range from 3 to 5, and the temperature is 40 DEG C; 5, secondary
impurity removing, wherein impurities of the bleached paper pulp are removed; 6, forming, wherein wet paper web is formed through a net feeding device; 7,
drying, wherein the wet paper web enters a pressure-shoe-shaped squeezing part for
dewatering pressing, the squeezed wet paper web enters a
drying cylinder to be dried, and the finished paper is obtained after
cutting.
