Abstract
The invention discloses a cotton stalk natural colour semichemical mechanical pulp process. The cotton stalk natural colour semichemical mechanical pulp process comprises the following steps: crushing, dedusting, softening, obtaining coarse pulp, deslagging, and carrying out coarse grinding so as to complete the whole set of the process. The cotton stalk natural colour semichemical mechanical pulp process provided by the invention has the advantages that the operation is simple and easy, and no large or complex equipment is needed, and the cotton stalk natural colour semichemical mechanical pulp process is more environmentally friendly compared with the prior art.
Description
Technical field
The present invention relates to a kind of cotton stalk true qualities semichemical mechanical pulping technique, belong to paper technology.
Background technology
Due to paper grades requirement, especially some cardboards and industrial and technical paper do not need higher whiteness, as long as the pulp washing therefore by obtained for boiling is clean, the paper pulp of the tone of maintenance own is exactly true qualities paper pulp.
True qualities paper pulp mainly divides true qualities straw pulp, true qualities bamboo pulp and true qualities wood pulp etc.
Wherein, true qualities straw pulp mainly adopts various annual crops stalk, and if maize straw, wheat straw waste etc. are main raw material, draw materials convenience, environmental protection, low-carbon (LC), the feedstock circulation cycle is short.
" true qualities " magma technology extracts the natural plant fibre such as stalk, timber, by clean for pulp washing obtained for boiling, keeps the natural gray of string 100%, the omnidistance a kind of pulping technique not using the chemicals such as bleaching agent
True qualities paper pulp comprises chemical pulp, semi-chemical pulp and mechanical pulp.If cement bag paper, cable paper, kraft capacitor paper etc. are all be made up of true qualities sulfate wood pulp.Purity refined stock.Pulping process main at present, the alkali recovery technology mature and reliable of its cooking waste liquor, but equipment is more complicated, investment large.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of cotton stalk true qualities semichemical mechanical pulping technique.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of cotton stalk true qualities semichemical mechanical pulping technique, through broken dedusting, softening, thick slurry, slagging-off corase grind, finally completes whole set process.
Preferably, above-mentioned cotton stalk true qualities semichemical mechanical pulping technique, concrete technology step is as follows:
1) after cotton stalk fragmentation, duplicate removal impurity and most of cotton stalk marrow;
2) the qualified cotton stalk after dedusting removal of impurities is transported in boiling vessel softens;
3) cotton stalk material after steaming is transported in press master, then after twin-screw thread rolling machine high-pressure impregnation sub-wire, in high-density paste mill, carries out defibrination, obtained thick slurry;
4) by slurry thick after mill after hydrabrusher disappears at a high speed and dives, remove the gred, fine grinding, is delivered to pond with slurry after screening is concentrated, removes machine room.
Preferred further, in described step 1), cotton stalk is broken into the material section of 35-50mm, is transported to goat's horn deduster, duplicate removal impurity and most of cotton stalk marrow.
Preferred further, described step 2) in, time softening, add the NaOH of 3%, the AQ of 0.05%, heat 3.5 hours under steam pressure 0.3MP.
Beneficial effect of the present invention:
Cotton stalk true qualities semichemical mechanical pulping technique provided by the invention, technique is simple to operation, and without the need to large complex device, to environment, comparatively prior art is more friendly.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1:
A kind of cotton stalk true qualities semichemical mechanical pulping technique, concrete technology step is as follows:
1) cotton stalk is broken into the material section of 35-50mm, is transported to goat's horn deduster, remove heavy seeds and most of cotton stalk marrows such as dust;
2) the qualified cotton stalk after dedusting removal of impurities is transported in boiling vessel softens, add the NaOH of 3%, the AQ of 0.05%, heat 3.5 hours under steam pressure 0.3MP;
3) cotton stalk material after steaming is transported in press master, then after twin-screw thread rolling machine high-pressure impregnation sub-wire, in high-density paste mill, carries out defibrination, obtained thick slurry;
4) by slurry thick after mill after hydrabrusher disappears at a high speed and dives, remove the gred, fine grinding, is delivered to pond with slurry after screening is concentrated, removes machine room.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
