What is the function of the press section in the production line of papermaking machinery?

The main function of press section of paper machine

Dehydration uses mechanical pressure to squeeze out the moisture in the wet paper, which greatly reduces the moisture content of the paper, reduces the load of the subsequent drying department, saves steam and improves the speed.

Improving the tightness and evenness of paper can make the fibers more closely combined, improve the evenness of paper, reduce the problems of loose paper, hair loss and powder loss, and improve the strength of paper.

Improve the surface properties of paper to make the paper surface smoother, reduce net marks, lay a good foundation for subsequent drying and calendering, and improve the appearance and printing adaptability of paper.

The fibers that enhance the physical strength of paper are interwoven under pressure, and the hydrogen bonding is increased, thus improving the key indexes of paper such as tensile strength, bursting strength and folding endurance.

Stabilizing the operation of the paper web makes the wet paper sheet denser and stiffer, reduces paper breakage and ensures the stable transfer of the paper web in the drying department.

Simple summary: mechanical dehydration, improving strength, improving paper surface, stable operation and reducing drying cost.
