Problems solved by technology

[0002] Absorbent paper is a kind of household paper. At present, the pure wood pulp absorbent paper on the market includes ordinary toilet paper, but toilet paper has limited water absorption and poor strength, especially after the paper is soaked, it is very easy to break and will remain on the wiped object
Traditional wet wipes are produced using non-woven materials, which are not easy to degrade and are not as environmentally friendly as pure wood pulp materials. Moreover, the wet wipes feel greasy, and they are easy to hang after wiping, which will bring inconvenience to users. great inconvenience

Embodiment 1

[0021] A preparation process of pure wood pulp fine grain absorbent paper, comprising the following steps: (1) mixing and pulping 50% of Beimu and 50% of rainbow fish, after pulping, it is decompressed by a decomposer and beaten by disc grinding, and the degree of beating is controlled at 23 degrees, wet weight 19g;

[0022] (2) The pulp after beating is stored in the pulping tank for pulp mixing. When mixing pulp, first add dry strength agent, the dosage is 5Kg / ton paper; then add wet strength agent, dosage 40Kg / ton paper; finally add softener , with an amount of 10Kg / ton of paper, all added at room temperature;

[0023] (3) Pump the above-mentioned prepared pulp to the flow delivery system, after dilution and screening, it is diluted to a concentration of 0.04% by the secondary flushing pump and pumped into the equal pressure pulp distributor, and then in the inclined wire paper machine Medium dehydration forming;

[0024] (4) After forming, the wet paper is pressed and dr...

Abstract

The invention relates to a preparation process of finely-corrugated pure wood pulp absorbent paper. The preparation process includes the steps of mixing 50% of northwood pulp with 50% of lebistes reticulatus, repulping and beating again with beating degree controlled within 23+ / -3 degrees; storing pulp obtained from beating in a pulp forming pool, and adding dry strength agents, wet strength agents and softening agents sequentially during pulp forming; pumping the formed pulp to a delivering system, diluting, screening, using a secondary pulp slushing pump to dilute again to obtain 0.04% of pulp and pumping the obtained 0.04% of pulp into an isobaric pulp distributor, and dewatering to shape wet paper sheets in an inclined wire paper machine; subjecting the shaped wet paper sheets to squeezing and drying in a large vat, corrugating by a corrugating device when the wet paper sheets are dried by 70-90%, drying the corrugated paper sheets in a large vat, winding and finally cutting to obtain finished absorbent paper, wherein a ceramic scraper in used as a corrugation scraper. The preparation process has the advantages that the prepared absorbent paper is high in water-absorbing performance and wet strength, less prone to breakage after being wetted and applicable to cleaning scrubbing in daily life.
