The dewatering elements of the paper making equipment used in the paper machine include wiper boards, forming boards, and vacuum suction tank panels. The pulp is leveled through the forming board while removing a small amount of moisture. Then enter the dehydration plate to scrape off the moisture, and finally enter the vacuum suction tank panel for vacuum forced dehydration. Next, let us learn more about the composition of the dewatering element of the paper making equipment. Here are some answers.

Wiper board.

The wiper board in the dewatering element of the paper making equipment can be selected according to the needs of single, two, three, five, and seven wipers. According to the paper type and vehicle speed produced by the paper machine, with a caster angle of 0-3 degrees, it can improve the formation of the paper and the dewatering effect. The wiper board is composed of a stainless steel box and a panel. It has 95 alumina ceramics, 99 alumina ceramics, and zirconia ceramics, and the base material is ultra-high molecular polyethylene or glass fiber reinforced plastic. The wiper board in the dewatering element of the paper making equipment has high wear resistance, good dewatering performance, and long service life. It can improve the uniformity and smoothness of the paper during use, and reduce the network consumption and energy consumption of the paper machine.


Forming board.

The forming board in the dewatering element of the paper making equipment is the first element under the breast roll of the paper machine. It can not only support the net and control the net section but also dewater. Its box body is made of stainless steel, the base material is ultra-high molecular weight polyethylene or FRP, and the panel is inlaid with ceramics. The typical structure of the forming board in the dewatering element of the paper making equipment is a long strip, while the forming board on a modern paper machine is usually a box composed of a wide flat beam plate and several small inclination chopping boards.

The vacuum suction box in the dehydration element of the paper making equipment is a device that uses the high-pressure difference between the inside and outside of the box to strengthen the dehydration. The box body is made of stainless steel, and the top cover is made of ceramic. The dryness of wet paper before passing through the vacuum box is about 2 to 3%, and after passing through the vacuum box, it can reach 10 to 14%, and the tightness of the paper is also improved.
