Abstract
The invention discloses the pulping process of a kind of environmental protection kraft paperboard, including: (1) first by American waste paper, Britain's waste paper and Europe waste paper according to certain ratio mix homogeneously, in the waste paper of mix homogeneously, add a certain proportion of wood pulp carry out pulping, during pulping, add a certain amount of enzyme;(2) pulping that step (1) obtains is carried out highly concentrated slagging-off and screening process again;(3) slurry after being screened by step (2) enters into classification workshop section step, and slurry is then divided into long fiber pulp, middle fiber pulp, short fibered pulp;(4) three kinds of slurries that step (3) classification obtains are sequentially passed through respective in low dense scummer carry out slag removal and purification;(5) slurry after slagging-off concentrated, get final product pulping after the technique such as dissipation of heat, mill.The present invention, by improving original pulping process, strictly controls the beating degree of slurry, temperature and ph value, produces lovely luster, and resistance to water, light resistance are strong, the environmental protection kraft paperboard that color is consistent.
Description
Technical field
The present invention relates to the slurry manufacture technology field of kraft paperboard, particularly relate to a kind of environmental protection kraft paperboard
Pulping process.
Background technology
There is dyestuff in domestic current slurry dyeing and keep low, plain boiled water difficult treatment, paper Color is poor
Etc. problem, client is more and more higher for the requirement of kraft paperboard, so to slurrying in the manufacturing process of kraft paperboard
The requirement of technique also gradually steps up, and is also required to carry out certain research design in the proportioning of waste material, raw-material by optimizing
Structure and improvement pulping process, the strict beating degree of slurry, temperature and the ph value of controlling also is critical step, so research sets
It is necessary for counting a kind of novel pulping process for improving the total quality of kraft paperboard.
Summary of the invention
In view of the foregoing, the invention provides the pulping process of a kind of environmental protection kraft paperboard, by control waste paper with
The mixed proportion of wood pulp, improves original pulping process, the strict control beating degree of slurry, temperature and ph value, can make outstanding
Pool is bright-coloured, and resistance to water, light resistance are strong, the environmental protection kraft paperboard that color is consistent.
For reaching above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is:
The pulping process of a kind of environmental protection kraft paperboard, comprises the following steps:
(1) first by American waste paper, Britain's waste paper and Europe waste paper according to certain ratio mix homogeneously, useless to mix homogeneously
Paper adds a certain proportion of wood pulp and carries out pulping, during pulping, add a certain amount of enzyme;
(2) pulping that step (1) obtains is carried out highly concentrated slagging-off and screening process again;
(3) slurry after being screened by step (2) enters into classification workshop section step, and slurry is then divided into long fiber pulp, middle fibre
Dimension slurry, short fibered pulp;
(4) three kinds of slurries that step (3) classification obtains are sequentially passed through respective in low dense scummer carry out slag removal and purification, slagging-off
Device exit is additionally provided with dyepump and the slurry after slagging-off is carried out dyestuff;
(5) slurry after slagging-off concentrated, get final product pulping after the technique such as dissipation of heat, mill.
Further, described scummer uses compact pot type scummer or drum-type scummer to remove the gred.
Further, described dyepump is frequency conversion type dyepump.
Further, in the part that described classification goes out, fiber pulp mixes with wood pulp as surface layer slurry, fiber in residue
Slurry is as sandwich layer, and long fiber pulp is bottom.
Due to the utilization of technique scheme, the present invention compared with prior art has a following beneficial effect:
By controlling the mixed proportion of waste paper and wood pulp, improve original pulping process, strict the control beating degree of slurry, temperature
With ph value, can produce lovely luster, resistance to water, light resistance are strong, the environmental protection kraft paperboard that color is consistent.
Detailed description of the invention
Below in conjunction with specific embodiment, present disclosure is described in further detail:
The pulping process of a kind of environmental protection kraft paperboard, comprises the following steps:
(1) first by American waste paper, Britain's waste paper, Europe waste paper and domestic waste paper according to certain ratio mix homogeneously, its mix
Composition and division in a proportion example is 2:3:2, adds foreign country's waste paper and can ensure that raw fibre length, intensity are big, adds one in the waste paper of mix homogeneously
The wood pulp of certainty ratio carries out pulping, adds a certain amount of enzyme during pulping, it is ensured that slurry keeps during pulping
Its intensity and fibre length;(2) pulping that step (1) obtains is carried out highly concentrated slagging-off and screening process again;(3) step is passed through
(2) slurry after screening enters into classification workshop section step, and slurry is then divided into long fiber pulp, middle fiber pulp, short fibered pulp;
(4) three kinds of slurries that step (3) classification obtains are sequentially passed through respective in low dense scummer carry out slag removal and purification, scummer goes out
It is additionally provided with dyepump at Kou and the slurry after slagging-off is carried out dyestuff;(5) to slagging-off after slurry concentrate, dissipation of heat, mill
Etc. getting final product pulping after technique, the strict surface layer slurry pulping degree that controls is 38-42 SR, and slurry temperature is 45-50 DEG C, and ph value is
6.5-7.0。
Further, described scummer uses compact pot type scummer or drum-type scummer to remove the gred.
Further, described dyepump is frequency conversion type dyepump.
Further, in the part that described classification goes out, fiber pulp mixes with wood pulp as surface layer slurry, fiber in residue
Slurry is as sandwich layer, and long fiber pulp is bottom.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and is carried out, and can not limit the scope of the invention with this, all according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within the scope of the present invention.
