Abstract

The invention provides a making method for bulking book paper, which comprises the steps of adding 10% of softwood pulp and 90% of hardwood pulp by mass percent in an aquapulper for defibering, beating the softwood pulp and the hardwood pulp respectively, pumping to a pulp proportioning chest for mixing, adding an intensifier and cationic starch with the mass accounting for 1.5% of the total mass of the pulp and a brightener with the mass accounting for 0.5-1.5% of the total mass of the pulp into the pulp proportioning chest, conveying to a pulp adjusting box from the pulp proportioning chest, conveying to a high-level box after the pulp passes through a desander and a centri-sorter, adding kieselguhr with the mass accounting for 1.5% of the total mass of the pulp and a retention aid with the mass accounting for 0.015% of the total mass of the pulp in the high-level box, allowing the pulp to enter a pulp flowing box, mounting a net, conducting forming and dehydrating through the net to obtain wet paper, allowing the wet paper to enter a squeezing part, controlling the squeezing pressure to further dehydrate, drying at a drying part, and further drying, calendering, winding, rewinding and slitting to obtain the bulking book paper after native starch is degraded by concentrated starch and chitosan is subjected to a surface sizing process. The method has the advantages that the printing cost is obviously lowered, and resources and energy are saved.

Description

The manufacture method of bulking(book) paper

Technical field

This area belongs to the manufacture method of paper, especially a kind of manufacture method of bulking(book) paper.

Background technology

When at present general printing paper smoothness was high, thickness was lower, and when thickness was relatively high, smoothness was lower, and paper is more coarse, and both can not take into account.

Summary of the invention

The present invention provides a kind of higher smoothness that has for overcoming the deficiencies in the prior art, and papery is fine and smooth, and printing density is high, the manufacture method of the bulking(book) paper that printing effect is good.

Technical scheme of the present invention is: the manufacture method of bulking(book) paper, mass fraction is that the hardwood pulp of 10% softwood pulp and 90% is put into hydrabrusher and discongested, afterwards it is pulled an oar respectively, then being evacuated to the with slurry pond mixes, in the with slurry pond, add the intensifier of slurry gross mass 1.5% and the brightening agent of cationic starch and 0.5-1.5%, deliver to stuff box by the with slurry pond, behind desander and selectifier, deliver to header box, in header box, add the diatomite of slurry gross mass 20% and 0.015% retention agent, then slurry enters head box, online, via after the wet end moulding dehydration, become l Water Paper, enter press section and control the laggard dehydration of squeeze pressure well, then carry out the drying section drying, after process starch extract degraded ative starch adds the surface sizing technique of shitosan, further dry, press polish is through batching, rewinding, cut and form.

The invention has the beneficial effects as follows: adopt the bulking(book) paper bulk of this explained hereafter to reach 1.50cm ³About/g, smoothness＞40s, not only high than general printing paper bulk, and have higher smoothness, can significantly reduce printing cost and economize on resources and the utilization of the energy.

Description of drawings

Fig. 1 is process chart of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

The manufacture method of bulking(book) paper, mass fraction is that the hardwood pulp of 10% softwood pulp and 90% is put into hydrabrusher and discongested, afterwards it is pulled an oar respectively, then being evacuated to the with slurry pond mixes, in the with slurry pond, add the intensifier of slurry gross mass 1.5% and the brightening agent of cationic starch and 0.5-1.5%, deliver to stuff box by the with slurry pond, behind desander and selectifier, deliver to header box, add the diatomite of slurry gross mass 20% and 0.015% retention agent in header box, then slurry enters head box, online, via after the wet end moulding dehydration, become l Water Paper, enter press section and control the laggard dehydration of squeeze pressure well, then carry out the drying section drying, after process starch extract degraded ative starch adds the surface sizing technique of shitosan, further dry, press polish is through batching, rewinding, cut and form.

Claims

1. the manufacture method of bulking(book) paper, it is characterized in that: mass fraction is that the hardwood pulp of 10% softwood pulp and 90% is put into hydrabrusher and discongested, afterwards it is pulled an oar respectively, then being evacuated to the with slurry pond mixes, in the with slurry pond, add the intensifier of slurry gross mass 1.5% and the brightening agent of cationic starch and 0.5-1.5%, deliver to stuff box by the with slurry pond, behind desander and selectifier, deliver to header box, in header box, add the diatomite of slurry gross mass 20% and 0.015% retention agent, then slurry enters head box, online, via after the wet end moulding dehydration, become l Water Paper, enter press section and control the laggard dehydration of squeeze pressure well, then carry out the drying section drying, after process starch extract degraded ative starch adds the surface sizing technique of shitosan, further dry, press polish is through batching, rewinding, cut and form.
