Abstract
The invention relates to a pulping method for waste Renminbi. The method adopts a caustic soda-anthraquinone pulping method. The process comprises stewing and bleaching, wherein alkali charge is controlled between 18% to 20% in the stewing, liquor ratio is 1:3.5-4.5, the stewing liquor temperature is 80 DEG C to 85 DEG C, and before the temperature rises, idling for 30 min, then rising temperature, and rising the temperature according to the temperature rising time and vapor pressure. By the adoption of the caustic soda-anthraquinone pulping method, the waste Renminbi is carried out by pulping, and the waste Renminbi can be fully resolved through controlling the stewing parameters, so that the pulping method for the waste Renminbi can be effectively used in papermaking system. Evenness of pulp got and full stuff efficiency are high, stewing quality is stable, and meanwhile usage amount of chemical materials is small and various energy consumptions are low, process investment is small, and the cost is low. The pulping method for the waste Renminbi achieves the recycle of waste resource, and meanwhile provides a novel pulp to the paper technology. The pulp of the process can be used for manufacturing specialty paper, and the pulping method for the waste Renminbi has a certain promotional value.
Description
Technical field
The present invention relates to the pulping technology for paper-making field, particularly relate to a kind of pulping process of waste and old RMB.
Background technology
In prior art, waste and old RMB uses after mostly adopting the machinery making beating, obtains in this way pulp fiber and is difficult to discongest, and contains a large amount of fibre bundles, causes the paper smoothness low, and sand holes are many, can not utilize well.
Summary of the invention
The object of the invention is to overcome the defective of above-mentioned prior art, providing a kind of can fully decompose waste and old RMB, effectively uses the waste and old RMB pulping process of copying in paper system.
The technical scheme of taking for achieving the above object is:
A kind of waste and old RMB pulping process is characterized in that adopting caustic soda-anthraquinone pulp-making method, and its technique comprises boiling and bleaching process, and wherein boiling parameter is:
1) alkali charge 18-20%,
2) liquor ratio 1: 3.5-4.5,
3) cooking liquor temperature 80-85 ℃,
4) boiling curve: after first dallying 30 minutes before heating up, can heat up, be warming up to rapidly 0.65MPa in 90 minutes, spurt after then being incubated 60 minutes.
Described bleaching process parameter is:
1) bleaching temperature is 35 ℃
2) bleaching time is 4 hours,
3) bleaching slurry concentration 4-5%,
4) bleached pulp whiteness 65-68% (blue light method mensuration),
5) bleached pulp fiber wet weight 4-5g.
Technical characterstic of the present invention be embodied in following some:
1) alkali charge is low, and liquor ratio is little.
2) pulping evenness obviously improves, and yield is high, and unscreened yield can reach 40-45%.
3) effectively digestion time is 3-3.5 hour.
The present invention adopts soda-aq cooking to carry out slurrying to waste and old RMB and processes, waste and old RMB fully can be decomposed by controlling the boiling parameter, copy paper system thereby effectively apply to, gained slurry evenness and pulping rate are high, cooking quality is stable, chemical materials use amount and every energy consumption are lower simultaneously, and technology investment is few, and cost is low.The present invention has realized the recycling of waste and old resource, and simultaneously also for paper technology provides new slurry kind, this process slurry can with the manufacturing paper with pulp of speciality paper, have certain promotional value.
The specific embodiment
The present invention adopts soda anthraquinone process take useless RMB as raw material, and selecting equipment is rotary spherical digester.Boiling and bleaching process parameter such as following table in the method:
During the cooking liquor configuration
1, according to using boiling alkali charge, liquor ratio, formulation cooking liquor concentration and volume.
2, determine concentration and volume after, use white liquid and the outsourcing caustic soda of alkali remanufacture to press, ratio is that 7:3 prepares.
3, the cooking liquor temperature must be heated to 80-85 ℃.
4, the cooking liquor that configures is feeded after adding spiral Presoaker and waste and old RMB uniform stirring.
5, after intensification must be dallied before, can heat up, heat up rapidly according to heating-up time, vapour pressure.
6, through after bleaching, the bleached pulp whiteness 65-68% of acquisition (blue light method mensuration), bleached pulp fiber wet weight 4-5g.
Claims (2)
1. a waste and old RMB pulping process, is characterized in that adopting caustic soda-anthraquinone pulp-making method, and its technique comprises boiling and bleaching, and wherein boiling parameter is:
1) alkali charge 18-20%,
2) liquor ratio 1:3.5-4.5,
3) cooking liquor temperature 80-85 ℃,
4) boiling curve: after first dallying 30 minutes before heating up, can heat up, be warming up to rapidly 0.65MPa in 90 minutes, spurt after then being incubated 60 minutes.
2. according to waste and old RMB pulping process claimed in claim 1, it is characterized in that described bleaching process parameter is:
1) bleaching temperature is 35 ℃
2) bleaching time is 4 hours,
3) bleaching slurry concentration 4-5%,
4) bleached pulp whiteness 65-68%,
5) bleached pulp fiber wet weight 4-5g.
