The quality of the installation of pulp and paper machinery and equipment is directly related to the performance of the paper machinery and equipment itself, so we need to continuously strengthen its quality control. The installation of papermaking machinery and equipment needs to formulate correspo

No matter how good the performance of the machine is, after a period of use, the paper machine may have various problems, especially which factors will affect the use of the paper machine​. Next, Tianyang will introduce it

In the 21st century, with the continuous improvement of scientific and technological level, the performance of domestic papermaking equipment has been significantly improved in all aspects. In recent years, with the continuous expansion of foreign market demand, the sales of papermaking machinery an

(1) Safety regulations for paper machine unwinding:1. Before going to work, check whether the buttons of the clothes are firm, and no hard objects are allowed in the pockets to prevent the lost surface from damaging the equipment.2. When handling the sticky pulp debris on the roller

Pulping is to separate the fibers from the raw materials of trees, make fiber pulp, and then bleach; papermaking is to dilute the fiber pulp, shape, press, dry, and then make paper. Both processes discharge large amounts of wastewater. The wastewater produced by pulping is seriously polluted. The pollutant concentration in the wastewater discharged during pulp washing is very high, the BOD is as high as 10-36g/L, and it contains a lot of plant fibers, inorganic salts and pigments. The wastewater discharged from the bleaching process also contains a large amount of acid and alkali substances. The wastewater discharged from the paper machine contains a large amount of fibers and fillers and sizing materials added during the production process.

The softness of toilet paper is often increased by wrinkling the paper sheet. There are many raw materials for the manufacture of toilet paper, commonly used are cotton pulp, wood pulp, straw pulp, waste paper pulp and so on.
