摘要: A waste paper recycling process comprises the following steps: putting into a container and pouring clear water to soak paper; shedding in shedder soakedwaste pulp fragments; placing obtained fragments an ultrasonic cleaning tank for treatment 10 minutes; adding deinking agent separate ink particles from fibers; then, adsorbent adsorb particles; by using high consistency stuff cleaner, then feeding impurity separator through conveying belt scum sediment pulp; adjusting pH value of 10, stabilizer Na2SiO3, heating 80DEG c, bleaching bleach forming bleached wet web slice, delivering pressure shoe-shaped squeezingpart be subjected dewatering forming, causing preliminarily dried; drying squeezed cylinder, cutting dried obtainfinished paper.
