What is the process of making toilet paper?

1. The waste paper enters the hydraulic pulper, which performs beating and deinking on the waste paper, and the pulps after beating and deinking flow into the pulp pool; The pulp is lifted from the pulp pool to the high-frequency vibrating screen by the pulp lifting pump, and the high-frequency vibrating screen plays the role of screening and separating impurities.

2. After screening, it flows into the pulp pool, and then it is lifted by the pulp pump into the rinsing machine for washing and bleaching.

3, automatically flowing into the pulp pool after bleaching; Then, the pulp is lifted into the refiner, ground into fine pulp, and then automatically flows into the pulp pool by the pulp pump, and then flows into the grit chamber. The function of the grit chamber is to precipitate and separate impurities such as sand ash, then make pure slurry, and then lift it to the slurry stabilizing box by the grit pump. Adjust the pulp concentration with a pulp stabilizing box, and then automatically flow into the net groove, then be brought into the drying cylinder by the net cage blanket, and enter the finished roll paper after drying.

4. After the roll paper enters the rewinder, the rewinding function is punching and embossing rewinding. The big roll is rewound into a small roll and then enters the slitting machine. The function of the slitter is to slit different specifications and lengths, and then package them into finished products.

application program

Toilet paper can be made entirely or partially from recycled fibers. We can study the use of old cartons as raw materials for toilet paper production. Using this raw material to make toilet paper, toilet paper and napkin has achieved good results. In fact, it is ridiculous to wipe your hands with toilet paper with whiteness of 89% and absorb liquid or industrial grease. The North American market has accepted this concept.

Another method is to develop thermo-mechanical pulp for producing toilet paper. At present, due to the rigidity and coarse fiber, the bonding strength of thermomechanical pulp is not enough, which reduces the strength of paper and produces dust during wrinkling, post-treatment and use. The appearance of enzyme may improve the adhesive strength of fiber, thus solving this problem.
