Abstract
A kind of high glaze high-intensity low-gramweight building cyclostyle base paper production technology, comprises the following steps：It is with slurry：By pulp from decoloured waste paper, aspen mechanical slurry is not bleached according to mass ratio 70 80%：20 30% do not bleach aspen mechanical starches with slurry, and during with slurry adds efficient wet strength agent according to 20 30kg/ tons oven dry stocks；The preparation process of the pulp from decoloured waste paper is as follows：U.S. useless 8# removes large stretch of impurity, through high concentration desanding device and compound scalping system through rotary drum hydrabrusher, the larger impurity of weight is removed, then the less impurity of weight is removed through low dense desander, through deinking flotation, part ink is removed, that is, makes the high Deinking Pulp of intensity；Manufacture paper with pulp：By step（1）The slurry being made into is directly over head box online and is molded into paper, then carries out press polish so that high temperature is closed pressurization by calender.Present invention process is simple, and the building cyclostyle base paper of manufacture has the advantages that smoothness is good, intensity is high, grammes per square metre is low and bulk is high.
Description
Technical field
The present invention relates to field of papermaking processes, specifically a kind of high glaze high-intensity low-gramweight building cyclostyle base paper life
Production. art.
Background technology
Building cyclostyle base paper is real estate construction market assistant product, is the intermediate base material for making building template paper, it is desirable to
Wet strength is high, inhales colloidality good.At present, the building cyclostyle base paper on market is mainly using domestic old and useless newspaper through simple processing life
Produce, grammes per square metre 65g/m2, smooth low, thickness is low, and being processed into building template paper needs suction glue amount big.
The content of the invention
To solve the drawbacks described above of prior art, it is high that the present invention proposes a kind of process is simple, high glaze with low cost
Low intensity grammes per square metre building cyclostyle base paper production technology.
Technical scheme is comprised the following steps：
（1）, it is with slurry：By pulp from decoloured waste paper, aspen mechanical slurry is not bleached according to mass ratio 70-80%：20-30% does not bleach poplar
Wooden mechanical pulp is with slurry, and during with slurry adds efficient wet strength agent according to 20-30kg/ tons oven dry stock；The pulp from decoloured waste paper
Preparation process it is as follows：U.S. useless 8# removes large stretch of impurity, through high concentration desanding device and compound scalping through rotary drum hydrabrusher
System, removes the larger impurity of weight, then removes the less impurity of weight through low dense desander, through deinking flotation, remove
Part ink, that is, make the high Deinking Pulp of intensity；
（2）, manufacture paper with pulp：By step（1）The slurry being made into is directly over head box online and is molded into paper, then by calender
So that high temperature closure pressurization is carried out press polish.
Such scheme also includes：It is described do not bleach aspen mechanical slurry be cut into slices using poplar after, through preimpregnation, defibrination system
Into.
Compared with prior art, it is as follows the characteristics of this technique：
1st, the efficient wet strength agent of addition 20-30kg/ ton paper during with slurry, consumption are low, and ripening is fast, and intensity is high, it is ensured that
Into after paper, wet tensile index is in 6.5-9.5 N.m/g, and do not affect to inhale colloidality energy；
2nd, middle addition of manufacturing paper with pulp is primary not to bleach aspen mechanical slurry, remains lignin using aspen mechanical slurry kind, and fiber is shorter,
Bulk can be increased, water absorbing properties are improved；
3rd, manufacture paper with pulp follow-up workshop section, and calender press polish improves into paper smoothness, market by the way of high temperature closure pressurization
Upper conventional building cyclostyle base paper is processed without press polish to ensure bulk, and smoothness only has 0-2s, and this technique productions
Smoothness 8-12s, due to smooth height, after making template, press polish smoothness is high, and quality scale is high；
4th, as bulk is high, 110-120 um are reached, the building cyclostyle base paper grammes per square metre of this technique productions is controlled in 60-
63g, as other product bulks, 2-5g lower than average grammes per square metre on market, grammes per square metre are reduced, and can be dropped during user is on probation
Low body paper consumption 3-7%；
5th, as smoothness is high, can guarantee that suction glue uniformly, the smooth height of glue surface makes Die plate paper, through compound with plank high
After Warm Extrusion, the building template glossiness of formation is high, and appearance looks elegant is welcome by market；
6th, body paper intensity can be improved using U.S. useless 8#, in the case of high wet strength and body paper intensity, can guarantee that impregnation mistake
Continuous paper in journey；As 8# waste paper fibres are long, and Die plate paper intermediate base material forms firm carrying isolation network, can guarantee that impregnation
Sizing material is concentrated mainly on template body paper two sides afterwards, not excessive permeation, can reduce inhaling glue amount, reduce Die plate paper cost.
Specific embodiment
The present invention is further disclosed with specific embodiment below.
A kind of high glaze high-intensity low-gramweight building cyclostyle base paper production technology, comprises the following steps：
（1）, it is with slurry：By pulp from decoloured waste paper, aspen mechanical slurry is not bleached according to mass ratio 70-80%：20-30% does not bleach poplar
Wooden mechanical pulp is with slurry, and during with slurry adds efficient wet strength agent according to 20-30kg/ tons oven dry stock；The pulp from decoloured waste paper
Preparation process it is as follows：U.S. useless 8# removes large stretch of impurity, through high concentration desanding device and compound scalping through rotary drum hydrabrusher
System, removes the larger impurity of weight, then removes the less impurity of weight through low dense desander, through deinking flotation, remove
Part ink, that is, make the high Deinking Pulp of intensity；It is described do not bleach aspen mechanical slurry be cut into slices using poplar after, through pre-
Leaching, defibrination are made.
（2）, manufacture paper with pulp：By step（1）The slurry being made into is directly over head box online and is molded into paper, then by calender
So that high temperature closure pressurization is carried out press polish.
The technical specification of building cyclostyle base paper prepared by above-mentioned technique is：Wet tensile index is in 6.5-9.5 N.m/g；It is smooth
Degree 8-12s；Bulk 110-120 um；By actually used, in the case of high wet strength and body paper intensity, impregnation is can guarantee that
During continuous paper；As 8# waste paper fibres are long, and Die plate paper intermediate base material forms firm carrying isolation network, can guarantee that leaching
After glue, sizing material is concentrated mainly on template body paper two sides, not excessive permeation, can reduce inhaling glue amount, reduce Die plate paper cost.And by
In grammes per square metre it is low, bulk is high reduces building template paper paper consumption and sizing material consumption, has saved natural resourcess.
