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.
The main function of pulping equipment in the production line of the paper machine is very important. Shredded, continuously finer fibers, can be very good for the next production line of the paper machine.
Papermaking wastewater treatment equipment is a kind of advanced immersion or tubular membrane separation technology, which can effectively solve the problem of membrane blockage, so as to ensure the long-term operation of the system and achieve long-term environmental protection.
The paper machine production line is a large-scale continuous production line mainly composed of papermaking equipment, pulping equipment and processing equipment. The equipment has a long process flow, many systems and complex specifications and models.
Paper is one of the four great inventions in ancient China. As early as 105 AD, Cai Lun summed up the use of hemp since the Western Han Dynasty.
Many domestic paper mills often encounter the phenomenon of drying cylinder sticking in the production process. This phenomenon may cause the paper surface to be not smooth enough, the wrinkles to be uneven in thickness, and in severe cases, it will cause holes or opaque spots, and sometimes have to
