Abstract
The invention discloses paper making technology of ultra lightweight tissue paper.The paper making technology of ultra lightweight tissue paper comprises following steps: pulp scattering, de-slagging, pulp refining, dilution, screening, netting and forming, squeeze dehydration, drying, wrinkling and primary rolling. A drying cylinder coating is adopted for softening, adjusting and wrinkling the scraper angle. During the paper making process, the frequency of shutdown due to paper-breaking is decreased by adding measures such as increase in paper weight in a transverse direction of a paper machine so that operation efficiency of the paper machine is increased.
Description
Technical field
The present invention relates to one way of life paper using papermaking process technical field, particularly relate to a kind of papermaking process of ultra-low quantitative tissue paper.
Background technology
Ultra-low quantitative paper for daily use due to quantitative comparison low, time wrinkling, the intensity of paper can be lost a lot, easily causes disconnected paper.Paper is all generally disconnect from both sides, thus causes whole paper web to disconnect, and can waste a lot of slurries and energy consumption, reduce the operational efficiency of paper machine during paper injection.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of papermaking process of ultra-low quantitative tissue paper, comprising loose slurry, slagging-off; defibrination, with slurry, dilution; screening, Top wire former, dewatering press; dry; wrinkling, just roll up, adopt and drying cylinder coating done soft, adjustment creping doctor angle, in the process of manufacturing paper with pulp; wait measure to reduce the number of times of downer the quantitative of paper that transversely increase of paper machine, improve the operational efficiency of paper machine.
The papermaking process technical scheme of a kind of ultra-low quantitative tissue paper of the present invention is, comprises loose slurry, slagging-off, defibrination, with slurry, dilution, screening, Top wire former, and dewatering press, dries, wrinkling, just rolls up,
(1) drying cylinder coating is done soft, and the present invention makes its quality softer by the sticky cylinder agent of adjustment and remover ratio; Paper is easily peeled off from drying cylinder, and paper loss of strength when wrinkling is little, and easily broken paper do not allowed by paper; Control coating according to the method for patent CN201310194553, keep coating to be positioned at soft coating;
(2) creping doctor angle 12 ° to 18 °, angle is larger, less to the strength failure of paper, and paper is not easy to disconnect, and wrinkle is fine and smooth, paper soft handle;
(3) in the process of manufacturing paper with pulp; increase quantitatively on trimming; width is within 7CM; quantitative height, the intensity of paper also just adds, and reduces the number of times of downer; improve the operational efficiency of paper machine; paper has trimming operation in aft-loaded airfoil process, and quantitatively high trimming, both sides can be cut off, and can not affect the quality of final finished like this.
Described ultra-low quantitative tissue paper is the wrinkling tissue paper of 10-13g/ ㎡.
The measure that step (1) adopts is, sticky cylinder agent and remover weight ratio are adjusted to 6-4:3.
Preferably, the measure that step (1) adopts is, sticky cylinder agent and remover weight ratio are adjusted to 4:3.
Step quantitatively improves 3-15% in (3).
Preferably, quantitatively 5-10% is improved in step (3).
Drying cylinder speed is 1750m/min, drying cylinder pressure 3.5-5.5bar.
Crepe ratio >=17%.
Squeeze pressure 90Kn/m.
Employing with slurry long fine 20 ± 2% and short fiber 80 ± 2%.
The papermaking process beneficial effect of a kind of ultra-low quantitative tissue paper of the present invention is: (1) drying cylinder coating is made the soft paper that makes and easily peeled off from drying cylinder, and paper loss of strength when wrinkling is little, and easily broken paper do not allowed by paper; Control coating according to the method for patent CN201310194553, keep coating to be positioned at soft coating;
(2) creping doctor angle creping doctor angle 12 ° to 18 °, angle is larger, less to the strength failure of paper, and paper is not easy to disconnect, and wrinkle is fine and smooth, paper soft handle;
(3) in the process of manufacturing paper with pulp; the quantitative of paper is transversely increased at paper machine; quantitative height; the intensity of paper also just adds; reduce the number of times of downer, improve the operational efficiency of paper machine, paper has trimming operation in aft-loaded airfoil process; quantitatively high trimming, both sides can be cut off, and can not affect the quality of final finished like this.
Reduce the number of times of downer, improve the operational efficiency of paper machine, improve disconnected paper rate can be reduced by 20% by the technology of the present invention.
detailed description of the invention:
In order to understand the present invention better, describe technical scheme of the present invention in detail with instantiation below, but the present invention is not limited thereto.
The papermaking process of a kind of ultra-low quantitative tissue paper of the present invention, comprises loose slurry, slagging-off, defibrination, with slurry, dilution, screening, Top wire former, and dewatering press, dries, wrinkling, just rolls up.
Drying cylinder coating is done soft, and paper is easily peeled off from drying cylinder, and paper loss of strength when wrinkling is little, and easily broken paper do not allowed by paper.
Creping doctor angle 12 ° to 18 °, angle is larger, less to the strength failure of paper, and paper is not easy to disconnect, and wrinkle is fine and smooth, paper soft handle.
In the process of manufacturing paper with pulp, transversely increase the quantitative of paper at paper machine, quantitatively high, the intensity of paper also just adds, and reduces the number of times of downer, improves the operational efficiency of paper machine.Paper has trimming operation in aft-loaded airfoil process, and quantitatively high trimming, both sides can be cut off, and can not affect the quality of final finished like this.Wherein, quantitatively 3-15% is improved.
