Abstract
The invention discloses a cotton stalk bleached chemi-mechanical pulp process. Cotton stalks are broken, purified and dipped, and then are rolled in two phases, and are ground into high-concentration thick liquid, and then are subjected to a latency process, and then are subjected to an accurate grinding process, a screening process and a concentration process. The cotton stalk bleached chemi-mechanical pulp process aims at the characteristic of the cotton stalks, the cotton stalk bleached chemi-mechanical pulp process is simple and easy to operate, and does not need large complex equipment, and compared with the prior art, the cotton stalk bleached chemi-mechanical pulp technology is more friendly to the environment, and high in performance and low in cost.
Description
Technical field
The present invention relates to a kind of cotton stalk bleached chemi-mechanical pulp technique, belong to field of papermaking processes.
Background technology
Cotton stalk is agriculture and forestry waste resource, and adopting pollution-free chemical mechanical pulping cleaning pulping new technology, carry out advanced treating, obtain the high-quality pulp being suitable for papermaking to this kind of waste resource, is the innovation to traditional chemical pulping and creation.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of cotton stalk bleached chemi-mechanical pulp technique.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of cotton stalk bleached chemi-mechanical pulp technique, point two sections of thread rollings and high consistency refining after broken removal of impurities, dipping, then after the latent technique that disappears except pool, fine grinding, screening, concentrated after.
Preferably, above-mentioned cotton stalk bleached chemi-mechanical pulp technique, concrete technology step is as follows:
1) remove impurity after cotton stalk fragmentation, dehydration rear screw is transported to two spiral shell stalk thread rolling machine after being delivered to and fully flooding in boiling vessel;
2) in first paragraph thread rolling machine, after thread rolling, the paramount dense reaction warehouse of slurry conveying leaves standstill.
3) through step 2) leave standstill after slurry through one section of press master clean dehydration after, carry out second segment rub with the hands mill sub-wire, carry after thread rolling paramount dense reaction warehouse leave standstill.
4) by leave standstill after slurry after two sections of press masters, carry out high consistency refining.
5) by slurry thick after mill through hydrabrusher disappear at a high speed dive after carry out removing the gred, refine, screen, concentrated after be delivered to pond with slurry, remove machine room.
Preferably, described step 1) in, cotton stalk is broken into the equal refining section of 35-50mm, is transported in twin drum material washing machine and removes impurity.
Preferably, described step 1) in, digestion time 30min in boiling vessel.
Preferably, described step 2), be specially: in first paragraph thread rolling machine, add 3% NaOH, 0.1% sodium phosphate trimer, 5% hydrogen peroxide, after thread rolling, the paramount dense reaction warehouse of slurry conveying leaves standstill 40min.
Preferably, described step 3) in, during second segment thread rolling, add the NaOH of 3.5% at thread rolling machine, the EDTA of 0.1%, the Na of 1%
2siO
