Abstract
The invention relates to the field of papermaking, provides a method for producing copy paper from waste stainless steel lining paper, and solves the problems of high production cost and high pulpingpower consumption of the copy paper in the prior art. The specific preparation method comprises the following steps: a, treating softwood pulp by a hydrapulper I, a pulp tank I, a disc mill I and a pulp tank II; b, treating waste stainless steel lining paper by a hydrapulper II, a pulp tank III, a fluffer, a pressure screen, a desander, a pulp tank IV, a disc mill II and a pulp tank V; c, sendingthe softwood pulp and the waste stainless steel lining paper which are treated in steps a and b into a pulp mixing tank together for treatment, adding a brightener and purple and blue dye to the pulpmixing tank, treating the mixture in a pre-making tank, then mixing the pulp in a pulp mixing tank, adding an accelerant to the pulp mixing tank, feeding the mixture to a pulp flushing tank, adding adefoaming agent to the pulp flushing tank, then performing treatment in a head box, mesh cloth, a pressing part, a dryer part and a coiling part, and performing slitting, packaging and warehousing treatment. A dryer stripping agent is added to the dryer part.
