TECHNOLOGICAL INNOVATION
FOCUS PAPER MACHINE - Moisture Control System uniformly humidifies the paper web while delivering an optimal cross-machine moisture profile. By humidifying one side of the paper web, it effectively minimizes longitudinal ridging. Additionally, after web breaks or during startup following grade changes, it enables faster production of qualified paper. While enhancing paper quality, it simultaneously improves the winding performance of the rewinder, thereby reducing trim loss. It also allows the paper to achieve higher moisture content or faster machine speeds at the winding section (suitable for paper machines with a maximum speed of 1500 meters per minute and a maximum web width of 8.5 meters).
With its innovative nozzle and valve technology, FOCUS PAPER MACHINE - Moisture Control System meets the requirements for optimal spray quality and precise spray monitoring essential for effective humidification.
Benefits of Applying FOCUS PAPER MACHINE - Moisture Control System
1. Ensure uniform moisture distribution across the entire paper web.
2. Enhance the smoothness of the paper.
3. Improve the overall quality of the paper.
4. Increase the overall web moisture by 2-3 percentage points.
(If the moisture content on both sides is consistent with that in the middle, the overall web moisture can be increased simultaneously.)
5. Reduce wavy edges after rewinding and minimize waste paper generation.
(Excessively dry edges of the paper web tend to absorb moisture after rewinding, forming wavy edges and resulting in waste paper.)
6.Reduce wear on both ends of the calender and extend its service life.
7. Save pulp consumption.
8.Eliminate longitudinal ridging and reduce web breaks.
According to the performance of the base paper and the speed of the machine, the amount of glue applied to each side can be adjusted individually. It still has good coverage at lower coating weights. Wide process range from sizing to high solids coating. Wide speed adaptation.
Zone controllable middle and high rollers can finely adjust the width difference of paper web thickness.
Good finishing effect can be obtained by using high temperature soft calendering.
Since the linear pressure in the nip and the temperature of the hot roll can be precisely controlled separately, the surface quality of the finished paper web is greatly improved, and the difference between the two sides and the width is very small.
With the rapid development of the paper industry and the rapid increase of the speed of the paper machine, there are higher requirements for the dehydration effect of the press section.
As a new type of design, shoe press can achieve gentle dehydration of paper sheets and improve press dryness. At the same time, it adopts a special press design, which greatly reduces energy demand, thereby reducing operating costs, and is favored by customers.
Compared with the roller press, the dryness of the paper surface of the shoe press is obviously improved, and the bulk is higher, and the felt pattern is shallower.
Practice has proved that the shoe press technology is the most advanced dehydration technology for cardboard, packaging paper and cultural paper. It has great advantages in changing the longitudinal pressure and independently adjusting the nip width and line pressure.
