Embodiment 1
[0020] During production, first soak the collected waste cardboard boxes, waste magazines and old newspapers in water, soak for 20-24 hours, put them into a pulverizer for grinding, and remove impurities, slag and coarse fibers, so that the remaining fiber slurry The length of the fiber is 1.0-1.5mm, and the slurry is used for standby to obtain the screened fiber slurry; the screened fiber slurry is subjected to beating and mixing treatment, and the fiber slurry is firstly beaten, and the beating degree is controlled at 25° SR, the humidity is controlled at 3g, and then the slurry is mixed to obtain a uniformly mixed slurry, which is left to stand for 120 minutes, and the slurry concentration is controlled at 1.2%, to obtain the slurry for preparing paper; the obtained slurry for preparing paper is strengthened , Put the enhancer into the paper slurry for mixing and stirring, mix well and stand still for 80 minutes, the enhancer is composed of 6 parts of vaguely copolymer, 3 pa...
