Abstract
The invention discloses a production method for a high-bulk grey board. The production method is characterized in that when pulp required for a surface lining and a bottom lining is prepared, mechanical pulp is added into deinked pulp for preparing the surface lining and mixed waste paper pulp for preparing the bottom lining respectively in a pulp mixing process. compared with the grey board processed by a traditional method, the high-bulk grey board processed by the production method provided by the invention has the advantages as follows: the gram weight is low on the premises that the thicknesses are equal and the product performances are ensured, conversely, the thickness is 12 percent lager than that of the traditional grey board on the premise of equal gram weights; and as the gram weight of the high-bulk grey board is low under the condition of equal thicknesses, so that the consumption of paper pulp is reduced, the consumption of corresponding fiber resource is reduced, and meanwhile the energy consumption during transport is also reduced, so as to correspondingly reduce the emission of carbon dioxide and facilitate the environment protection and resource protection.
Description
Technical field
The present invention relates to the production method of cardboard in paper-making industry, particularly relate to a kind of production method of high-bulk grey board.
Background technology
At present, product external packagings a lot of on market is all adopt carton package, and carton is all processed by cardboard, therefore causes the consumption of cardboard also very large.And white board of the grey end in the market; for ensureing the properties of product of cardboard; as: deflection, withstand voltage, folding strength etc.; in the cal(l)iper that enterprise produces defined, its grammes per square metre is larger; this just causes the amount ratio of paper pulp in the production process of ash end white board larger; the consumption of its corresponding fibre resources is also larger, is unfavorable for the protection of environment and resources.
Summary of the invention
Under technical problem to be solved by this invention is to provide a kind of prerequisite ensureing properties of product, the production method of the high-bulk grey board that its grammes per square metre is smaller in same thickness.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of production method of high-bulk grey board, and its concrete production process is:
(1), by size degradation, screening, purification, flotation, heat partition, bleaching, defibrination and mixed starch the slurry prepared needed for surface layer, face lining, sandwich layer, bottom lining layer and bottom;
(2), by the slurry approach system for the preparation of each pulp layer delivering to paper machine carries out manufacturing paper with pulp shaping, prepares surface layer, face lining, sandwich layer, bottom lining layer and bottom respectively;
(3), prepare by dissolving, blending, reaction, filtration treatment appear precoated shet and the coating needed for the finishing coat of face;
(4), each pulp layer is carried out press dewatering and be compounded to form cardboard, and drying process is carried out to cardboard, then respectively WATER REPELLENT TREATMENT (i.e. applying glue) is carried out to the surface of surface layer and bottom, the coating forming surface pre-coating layer prepared and face, face coating layer is coated again successively on surface layer, finally press polish, cut paper and choosing reason are carried out to cardboard, produce qualified high-bulk grey board;
In described step (1), when preparing the slurry needed for face lining and bottom lining layer, in the Deinking Pulp for the preparation of face lining and the mixed waste pulp for the preparation of bottom lining layer, mechanical pulp is added respectively in mixed slurry process, the adding proportion wherein controlling Deinking Pulp and mechanical pulp is 1:1.5 ~ 2, the adding proportion of mixed waste pulp and mechanical pulp is 1:0.4 ~ 0.5, and mix, obtain the slurry for the preparation of face lining and bottom lining layer respectively;
In described step (2), when manufacturing paper with pulp face lining and bottom lining layer, when the grammes per square metre of chain of command lining is the tradition ash end white board of preparation same thickness face lining grammes per square metre 90 ~ 92%, when the grammes per square metre controlling bottom lining layer is the tradition ash end white board of preparation same thickness bottom lining layer grammes per square metre 90 ~ 92%.
The concrete preparation process of described mechanical pulp is: in wood pulp, add sulphite, the mass percentage controlling sulphite is 1 ~ 7% of wood pulp, and be heated to 120 ~ 135 DEG C, dipping 2 ~ 5min, then wood pulp is sent in disc mill and pull an oar, when the freeness of wood pulp is 320 ± 20ml, completes pulping process, obtain mechanical pulp; Can be discongested and wire-dividing broom purification the fiber of wood pulp by making beating, improve into paper product matter.
Described sulphite is sodium sulfite or sodium dithionite.
Compared with prior art, advantage of the present invention processes the high-bulk grey board that obtains and conventional method by this method to process compared with the white board of the grey end that obtains, thickness identical and ensure cardboard properties of product (as high in deflection, folding strength is high, good, the surperficial evenness of resistance to pressure and smoothness good etc.) prerequisite under, its grammes per square metre is little, conversely speaking, under the prerequisite that grammes per square metre is identical, the thickness of the white board of the grey end that its Thickness Ratio is traditional is high by more than 12%; And when due to same thickness, the grammes per square metre of this cardboard is little, therefore the use amount of its paper pulp also reduces; corresponding fibre resources consumption also reduces; decrease energy resource consumption during transport simultaneously, decrease the discharge capacity of carbon dioxide accordingly, be conducive to the protection of environment and resources.
