The forming process of the paper web of the paper machine is the process in which the fiber suspension is dehydrated and deposited on the forming wire surface. It is mainly a hydrodynamic process; chemical forces and colloidal chemical forces also have a certain impact

The composition of the wire section of the Fourdrinier paper machine:The wire part of the Fourdrinier paper machine is referred to as the Fourdrinier wire or the wire case for short. It is a typical fourdrinier network department. The main component of the net case is an endless fine woven net.

The function of the breast roller on the Fourdrinier paper machine:The breast roll is the first roll on the paper machine and is the beginning of the screen. One of its functions is to support the forming wire. The forming wire changes direction on the breast roll.

The forming plate (also called the tissue plate) is the first element under the net behind the breast roll of the Fourdrinier paper machine, and it plays the role of supporting the net and controlling the dehydration of the net section.As the width of the paper machine increases

The wet suction box on the paper machine is a low vacuum dewatering element with a vacuum degree of 0.2-1kPa. The box surface is composed of multiple chopping boards, and there are also open-hole panels. The opening rate is more than 50%. The material is the same as the chopping board.

Dewatering process of vacuum suction box of Fourdrinier paper machineOn the vacuum water tank of the paper machine, the wet paper web has been basically shaped, and its main purpose is to dewater.For the vacuum suction box at low speed and low vacuum, the dehydration process of the wet paper web on a vacuum suction box can be roughly divided into three stages.
