Toilet paper production process Analyze the whole process of high-quality toilet paper production---Fujian disc paper slitting rewinder

The waste paper enters the hydraulic pulper, and the hydraulic pulper performs beating and deinking of the waste paper. The pulp after beating and deinking flows into the pulp pond; the pulp pump is used to lift the pulp from the pulp pond into the high frequency vibrating screen. The vibrating screen plays the role of screening debris separation; after screening, it flows into the pulp tank, and then is carried into the rinsing machine by the pulp pump. The function is to clean the pulp and bleach; after bleaching, it automatically flows into the pulp tank; and then the pulp is lifted into the refiner. After being refined into a fine slurry, it automatically flows into the slurry tank and then is lifted into the sedimentation tray by the slurry pump. The function of the sedimentation tray is to precipitate and separate impurities such as sand and ash, and then make pure slurry, which is then lifted into a stable slurry by the de-sand pump. The function of the headbox and stabilizing headbox is to adjust the consistency of the pulp, and then automatically flow into the net trough, then the net cage blanket carries the pulp into the dryer. ---Fujian Paper Slitting and Rewinding Machine

(The dryer is used for drying) After entering the finished roll paper. After the paper is rolled, it enters the rewinding machine, and the function of rewinding is to play the role of rewinding, punching and embossing. It is rewinded from large rolls into small rolls, and then enters the slitting machine. The slitting machine functions as a slitting machine with different specifications and lengths, and then is packaged to the finished product.

Note: The boiler plays the role of hot air and is sent to the dryer to play the role of drying paper.

First of all, the toilet paper on the market includes coreless toilet paper without a paper tube, core toilet paper with a paper tube, and single roll toilet paper with plastic film packaging. The size of toilet paper varies, generally three-layer or four-layer composite of. ---Fujian Paper Slitting and Rewinding Machine

In addition, we will find that the toilet paper sold on the market is sugarcane pulp, mixed pulp, sprayed, and hanged, as well as the more popular bamboo pulp natural toilet paper. Open a roll of toilet paper and view it. All have embossing patterns, this is the effect of the full embossing device on the toilet paper rewinder.

And there is a convenient tear line in the middle of each piece of toilet paper. This professional name is called perforated line, which is achieved by the punching knife on the toilet paper rewinder. A pack of toilet paper is generally ten or twelve rolls. ---Fujian Paper Slitting and Rewinding Machine

Let’s take a look at the entire toilet paper processing process based on the above introduction. First, we purchase toilet paper raw materials from the paper mill, and then put it on the 1880 toilet paper rewinder. The machine will rewind it, fully embossed and beaten. Hole, spray glue finishing and other operations.

Then put the rewound strip of toilet paper on the band saw cutting machine, adjust the size of the toilet paper, push the panel to cut it into our common finished toilet paper, and finally put the toilet paper into the packaging bag. Then it is sealed and packaged by a water-cooled sealing machine, and then it can be sold to consumers. ---Fujian Paper Slitting and Rewinding Machine

Analyze the whole process of high-quality toilet paper production

Generally, high-quality toilet paper is made of wood, which is closely related to everyone's life in our daily life.

1. The role of dispersant and softener should not be ignored. Adding a proper dispersant to the net slurry can significantly improve the evenness of the paper and achieve the purpose of improving the softness and feel of the paper. At present, most domestic manufacturers use imported PEO-WF or domestically produced PEO as dispersant. When using PEO, pay attention to the selection of its molecular weight, the preparation method (preparation concentration and dissolution stirring speed), the control of the addition amount (generally 1.0 ~ 1.5 kg/t paper) and the influence of the production water quality. ---Fujian Paper Slitting and Rewinding Machine

2. The correct wrinkling process is the key to sending high-grade toilet paper. Wrinkling is to peel off the paper sheet close to the surface of the dryer, and the paper sheet is slightly curled to produce wrinkles.

3. Proper ratio of long and short fibers is the prerequisite for sending soft toilet paper. Long fiber pulp can give toilet paper sufficient strength, while short fiber pulp has a greater impact on hand feel, especially softness.

4. A good beating process is the guarantee for the production of soft toilet paper. For the papermaking of toilet paper, since pulps with different fiber lengths are used as raw materials, the beating process must be strictly controlled. Generally speaking, long fiber pulp must be beaten to give toilet paper sufficient strength. Its beating degree can be controlled at 30-45"SR, while short fiber or waste paper pulp is mainly decomposed, supplemented by light cutting , Its beating degree can be controlled in 20～30"SR. The beating degree of the online slurry is generally controlled at 28-40. SR. ---Fujian Paper Slitting and Rewinding Machine
