Embodiment 1

[0025] Embodiment 1: As shown in the accompanying drawing, the mass concentration of 100% bleached sulfite eucalyptus pulp is adjusted with water to form a mass concentration of 3% slurry, and then the slurry is pulped by No. 1 hydraulic pulper and entered into No. 1 pulp pool , and then the slurry in the No. 1 pulp pool is decomposed by the deflagging machine, and the coarse fiber is ground by the disc refiner, and then enters the No. 2 pulp pool; then the slurry in the No. Put in PPE papermaking wet strength agent and mix to obtain finished slurry, wherein the amount of PPE papermaking wet strength agent added is 18 kg per ton of paper; the finished slurry is transported to No. 5 finished pulp tank, and pumped into the No. 5 finished pulp tank The pulp is sent to the No. 6 overflow pulp tank and the overflow pulp tank is always full. The overflow pulp tank flows into the No. 5 finished pulp tank through the overflow pipe, and the No. 6 overflow pulp tank The mass concentrati...

Embodiment 2

[0026] Embodiment 2: 100% mass concentration 100% bleached sulfite eucalyptus pulp is added with water and adjusted to a mass concentration of 4% slurry, and then the slurry enters No. 1 pulp tank through pulper pulping, and the slurry in No. 1 pulp storage tank After being decomposed by a deflaker and coarsely ground by a disc refiner, it enters the No. 2 pulp tank; then the slurry in the No. 2 pulp tank is transported to the pulp mixing box, and at the same time, PPE papermaking wet strength agent is put into the pulp mixing box and mixed to obtain finished pulp The amount of PPE papermaking wet strength agent added is 20 kg per ton of paper; the finished slurry is transported to the No. 5 finished stock tank, and the pump is used to send the slurry in the No. 5 finished stock tank to the No. 6 overflow pulp and make the overflow stock tank always full. The overflow stock from the overflow stock tank flows into No. 5 finished stock stock through the overflow pipe. Adjusted t...

Embodiment 3

[0027] Embodiment 3: It is basically the same as Embodiment 1, except that the bleached sulfite eucalyptus pulp with a mass concentration of 100% is adjusted to a slurry with a mass concentration of 3.5% by adding water.

Abstract

The invention discloses a method for manufacturing cotton white paper. In the method, the bleached sulfite eucalyptus pulp is used as a raw material and processed; and then, the processed raw material is sequentially subject to processes of material mixing, pulping, one-step slag removing, diluting, secondary slag removing, pulp stabilization, pulp flow and formation, squeezing, drying and coiling to obtain the cotton white paper, wherein in the process of material mixing , PPE (polyphenyl ether) is used as a papermaking wet strength agent. The invention has the advantage of simple and environmental-friendly process; by adopting the bleached sulfite eucalyptus pulp as the raw material, the production cost can be greatly reduced, the adaptability, optical performance, flexibility, loose thickness, wet strength and permeability of the paper can be improved, and the appearance can be smooth and fine; and by adopting the PPE as the papermaking wet strength agent, the flexibility and the water absorbing performance of the paper can be improved.

Description

technical field [0001] The invention relates to a method for manufacturing paper, in particular to a method for manufacturing cotton white paper. Background technique [0002] Paper is a sheet-like fibrous product used for various purposes such as writing, recording, printing, drawing or packaging. According to the production method, it is divided into handmade paper and machine-made paper. Handmade paper is mainly operated by hand, and the disadvantage is that the output is small; machine-made paper refers to the general term for paper produced by mechanization, such as printing paper and packaging paper. According to the thickness and weight of the paper, it is divided into paper and cardboard. Generally, the weight below 200g per square meter is called paper, and the above is called cardboard. According to the purpose, it is divided into: newsprint, printing paper, writing paper, packaging paper, technical paper, sanitary paper, processing base paper, cardboard and proce...
