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.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for producing copy paper by using waste stainless steel backing paper. Background technique [0002] Copy paper is a high-grade double-sided glossy thin paper used for packaging and decoration of high-end articles. It has the characteristics of fine paper quality, good uniformity, high whiteness, and good transparency. Its production requires highly fibrillated fibers, good swelling and hydration, high viscosity beating, and beating degree up to 900SR or more, so the water filtration is slow, and the paper machine speed cannot be too high, so the output of a single machine is not high, which is relatively high. Paper grades that are difficult to produce. [0003] 100% commercial softwood pulp is generally used in domestic copy paper production. Mainly due to the sticky matter contained in the recycled pulp, it is easy to cause phenomena such as sticking to the net, sticking ...
