(2) soak: filament raw material is put into the fermentation vat filling chemical agent and soaks, temperature during immersion is 25-35 DEG C, constantly stir in immersion process, soak after 3-4 hour, add paraffin again to stir, and after keeping 15-20 minute after being slowly heated to 90-100 DEG C, namely obtain coarse particles after cooling;
(3) paper is washed: put into service sink and add water by soaking obtained coarse particles and wash by rubbing with the hands, carry out bleaching simultaneously, and filtering and impurity removing matter;
(4) defibrination process is incited somebody to action: will wash pulp material and send into shove Water Extraction Machinery, and carrying out dewatering to concentration is 40-45%, the slurry after dehydration is put into pond with slurry, is mixed with the middle underflow that concentration is 18-28%;
(5) sub-sieve and copy paper: the agriculture of preparation is starched and is sub-sieved into 140-180 order, then the paper pulp after sub-sieve is carried out copy paper, finally by the paper copied dry.
Preferably, the speed stirred when soaking in described step (2) is more than 3000rpm.
Preferably, described chemical agent comprises following component: be NaOH 6-12 part, hydrogen peroxide 2-6 part, water 100-120 part, sodium metasilicate 2-4 and sodium alkyl benzene sulfonate 1-3 part, reinforcing agent 1-3 part, described paraffin is 15-25 part.In the present invention, wherein reinforcing agent is acrylamide, polyvinyl alcohol, and glyoxal is cross-linked, one or more mixtures in carboxymethyl cellulose or natural plant gum.
Preferably, the material preparing described paper is one or more mixtures in stalk, timber, reed or bamboo.
In sum, technique effect of the present invention is mainly reflected in:
The pretreatment time of the present invention is short, energy consumption is low, equipment investment is little, by increasing chemical agent in the feed in industrial paper conversion process, make paper product yellowing resistance grow, meanwhile, the holding time extends greatly, simultaneously, the toughness of paper and soft flexibility can be increased, add the smoothness on paper surface, antistatic effect, the WATER RESISTANCE and the humidity resistance that improve paper good simultaneously, can be widely used in the technique paper usings such as printing, brown paper, cardboard, gasket paper.
