Description

A kind of grinding method of high beating degree copy paper
Technical field
The invention belongs to the refining process field of copy paper, be specifically related to the grinding method of a kind of high beating degree copy paper.
Background technology
Along with copy paper is constantly expanded in the purposes in each field, the prescription of copy paper is improved the most therewith.Produce height Beating degree high-quality copy paper is the highest to the requirement of refining process technology, particularly the form of the slurry drainage and formation shadow to online Ring the biggest.Fiberizer is one of visual plant of pulping and paper-making, and abrasive disc is the important component part of fiberizer, and slurry passes through defibrination The Moving plate of machine and price fixing interact, and pulp fiber is sheared under force and discongests, and cut-out is comprehensive with wire-dividing broom purification Effect directly affects the quality of slurry, and conservative control cuts off and the comprehensive function of wire-dividing broom purification, is by selecting suitable abrasive disc Profile of tooth, controls the pressure into slurry, concentration, refining plate interval realize.
Summary of the invention
The purpose of the present invention is providing the grinding method of a kind of high beating degree copy paper.
The grinding method of a kind of high beating degree copy paper, comprises the following steps:
(1) by weight water intaking 500 parts, 100 parts of slurry, hemicellulase 2 parts, cellulase 1 part, xylanase 1 Part and pectase 0.5 part, carry out being sufficiently mixed 3 hours by above-mentioned composition；
(2) slurry that step (1) processed is concentrated, be then added to filler 20 parts and mix；
(3) slurry processed of mixing in step (2) is concentrated again with filler, until being concentrated into shape is that bulk is Only；
(4) the block slurry in step (3) is ground into granule and is delivered to fiberizer；
(5) carrying out defibrination in fiberizer, defibrination adds water 500 parts and further defibrinations the most afterwards, for next step copy paper.
Further, described step (1) is specially following steps: slurry is soluble in water, discongests uniformly, then carries out pre-place Reason, the most first by pectase water dissolution, adds dimension element enzyme and xylanase, stirs 25 minutes with the rotating speeds of 25 revs/min, Then hemicellulase is added 1 part of Radix Aconiti Lateralis Preparata, 2 portions of Rhizoma Dioscoreaes, 2 portions of Fructus Crataegis, 2 parts of Fructus Hordei Germinatus (parched to brown)s and 2 parts of Pericarpium Citri Reticulataes to pulverize together and mix thoroughly, Finally with above-mentioned gained liquid mixing, stir 60 minutes with the rotating speeds of 55 revs/min, temperature 30 DEG C, pH=7-8, stand 10min Mix with pretreated slurry after filtration.
Further, slurry pretreatment is application of vacuum, and its concrete grammar is: add in vacuum pump 2 parts of dispersants, 2 parts Antifungus agent, 2 portions of preservative and 2 parts of defoamer are put into vacuum pump and are evacuated to 2.0 × 10-8Torr, by temperature in vacuum pump Being adjusted to 70 DEG C of bakings, vacuum pump internal gas pressure is raised to 2.5 × 10-7After Torr, toast 1 hour, return to 2.2 × 10 to pot internal gas pressure- 8Close baking after Torr, be finally cooled to room temperature.
The present invention has the high beating degree slurry function of production, alleviates the labor intensity of operator, it also avoid artificial The impact of factor, uses the control technology of automatization, keeps the balance of the concentration into slurry and pressure, improve the steady of defibrination quality Qualitative, reduce the defibrination power consumption of ton slurry, also ensure that paper machine produces the slurry of high beating degree copy paper.
Detailed description of the invention
The grinding method of a kind of high beating degree copy paper, comprises the following steps:
(1) by weight water intaking 500 parts, 100 parts of slurry, hemicellulase 2 parts, cellulase 1 part, xylanase 1 Part and pectase 0.5 part, carry out being sufficiently mixed 3 hours by above-mentioned composition；Slurry is soluble in water, discongest uniformly, then enter Row pretreatment, the most first by pectase water dissolution, adds dimension element enzyme and xylanase, stirs with the rotating speeds of 25 revs/min 25 minutes, then hemicellulase is added 1 part of Radix Aconiti Lateralis Preparata, 2 portions of Rhizoma Dioscoreaes, 2 portions of Fructus Crataegis, 2 parts of Fructus Hordei Germinatus (parched to brown)s and 2 parts of Pericarpium Citri Reticulatae powder together Broken mix thoroughly, last with above-mentioned gained liquid mixing, stir 60 minutes with the rotating speeds of 55 revs/min, temperature 30 DEG C, pH=7-8, quiet Put after 10min filters and mix with pretreated slurry.Slurry pretreatment is application of vacuum, and its concrete grammar is: at vacuum pump 2 parts of dispersants of middle interpolation, 2 parts of antifungus agents, 2 portions of preservative and 2 parts of defoamer are put into vacuum pump and are evacuated to 2.0 × 10- 8Torr, is adjusted to 70 DEG C of bakings by temperature in vacuum pump, and vacuum pump internal gas pressure is raised to 2.5 × 10-7After Torr, toast 1 hour, extremely Pot internal gas pressure returns to 2.2 × 10-8Close baking after Torr, be finally cooled to room temperature.
(2) slurry that step (1) processed is concentrated, be then added to filler 20 parts and mix；
(3) slurry processed of mixing in step (2) is concentrated again with filler, until being concentrated into shape is that bulk is Only；
