Description
Technical field
The present invention relates to a kind of paper for daily use papermaking process technical field, more particularly to a kind of ultra-low quantitative tissue paper
Papermaking process.
Background technology
Ultra-low quantitative paper for daily use is low due to quantitative comparison, during corrugation, and the intensity of paper can lose a lot, easily cause disconnected
Paper.Paper is typically all to be disconnected from both sides, so as to cause whole paper web to disconnect, many slurries and energy can be wasted during paper injection
Consumption, reduces the operational efficiency of paper machine.
The content of the invention
The purpose of the present invention provides a kind of papermaking process of ultra-low quantitative tissue paper aiming at above-mentioned defect,
Including dissipating slurry, slagging-off, defibrination is with slurry, dilutes, screening, Top wire former, and dewatering press is dried, corrugation, just volume, using by drying cylinder
Coating does soft, adjustment creping doctor angle, during manufacturing paper with pulp, and increases the quantitative of paper in the transverse direction of paper machine and waits measure to drop
The low number of times of downer, improves the operational efficiency of paper machine.
A kind of papermaking process technical scheme of ultra-low quantitative tissue paper of the present invention is, including dissipates slurry, and slagging-off, defibrination is matched somebody with somebody
Slurry, is diluted, screening, Top wire former, and dewatering press is dried, corrugation, just volume,
（1）Drying cylinder coating does soft, and the present invention makes its quality softer by the viscous cylinder agent of adjustment and remover ratio；So that paper
Easily peeled off from drying cylinder, paper loss of strength in corrugation is small, and paper does not allow easily broken paper；According to patent CN201310194553
Method control coating, keep coating be located at soft coating；
（2）12 ° to 18 ° of creping doctor angle, angle is bigger, smaller to the strength failure of paper, and paper is not easy to disconnect,
And wrinkle is fine and smooth, paper soft handle；
（3）During manufacturing paper with pulp, on trimming, increase is quantitative, and width is within 7CM, quantitative height, and the intensity of paper is also
Add, reduce the number of times of downer, improve the operational efficiency of paper machine, paper has trimming process during post-processing,
The quantitative high trimming in both sides can be cut off, and the quality of final finished is not interfered with so.
The ultra-low quantitative tissue paper is 10-13g/ ㎡ corrugation tissue paper.
Step（1）Viscous cylinder agent and remover weight ratio is are adjusted to 6-4 by the measure used:3.
It is preferred that, step（1）Viscous cylinder agent and remover weight ratio is are adjusted to 4 by the measure used:3.
Step（3）In quantitatively improve 3-15%.
It is preferred that, step（3）In quantitatively improve 5-10%.
Drying cylinder speed is 1750m/min, drying cylinder pressure 3.5-5.5bar.
Crepe ratio >=17%.
Squeeze pressure 90Kn/m.
It is with slurry using long fibre 20 ± 2% and short by fine 80 ± 2%.
A kind of papermaking process of ultra-low quantitative tissue paper of the present invention has the beneficial effect that：（1）Drying cylinder coating does soft so that paper
Zhang Rongyi is peeled off from drying cylinder, and paper loss of strength in corrugation is small, and paper does not allow easily broken paper；According to patent
CN201310194553 method control coating, keeps coating to be located at soft coating；
（2）12 ° to 18 ° of creping doctor angle creping doctor angle, angle is bigger, smaller to the strength failure of paper, paper
Open and be not easy to disconnect, and wrinkle is fine and smooth, paper soft handle；
（3）During manufacturing paper with pulp, increasing paper in the transverse direction of paper machine quantifies, quantitative height, and the intensity of paper is also
Add, reduce the number of times of downer, improve the operational efficiency of paper machine, paper has trimming process during post-processing,
The quantitative high trimming in both sides can be cut off, and the quality of final finished is not interfered with so.
The number of times of downer is reduced, the operational efficiency of paper machine is improved, being improved by the technology of the present invention can be by disconnected paper
Rate reduction by 20%.
Embodiment：
For a better understanding of the present invention, technical scheme is described in detail with instantiation below, but originally
Invention is not limited thereto.
A kind of papermaking process of ultra-low quantitative tissue paper of the present invention, including slurry is dissipated, slagging-off, defibrination is with slurry, dilutes, sieve
Choosing, Top wire former, dewatering press is dried, corrugation, just volume.
Drying cylinder coating does soft so that paper is easily peeled off from drying cylinder, and paper loss of strength in corrugation is small, and paper is not allowed
Easily broken paper.
12 ° to 18 ° of creping doctor angle, angle is bigger, smaller to the strength failure of paper, and paper is not easy to disconnect, and
Wrinkle is fine and smooth, paper soft handle.
During manufacturing paper with pulp, increase quantifying for paper in the transverse direction of paper machine, quantitative height, the intensity of paper is also increased by
, the number of times of downer is reduced, the operational efficiency of paper machine is improved.Paper has trimming process, both sides during post-processing
