Paper Making Press Polyester Mesh Belt For Paper Mills
Introduction:
Press felts play an important role in removing moisture from the paper web after the forming section, while imparting smoothness and transporting it to the dryer section. To this end, press felts need to provide the following functions: water removal, smoothing and runnability. In recent years, larger and faster paper machines require press felts of higher consistency and quality. According to the location on the paper machine can be divided into wet felts, top felt and dryer felt. The function of the wet felt is to press the raw paper to make it dehydrated and smooth the paper surface. The top felt is used above the wet felt and plays the role of leading, flattening paper and drying. Dryer felt wraps the dryer cylinder to iron and dry the paper.
Features:
- The press felts are well dehydrated and have a high dry content.
- press felts start quickly at maximum operating speed.
- Since the characteristics of press felts remain unchanged and the felt wear is less, the running time is long.
- The installation of joint press felts is safer, faster and simpler: installation time is shorter, less manpower required to replace felts, and cost savings are realized.
- Good energy consumption level.
Using Method of Paper Making Felt
1. Compare specification, size and weight with required standard
2. Find the facade with sign "The Side with Paper" before using, don't reverse it and operate it according to the arrow.
3. The felt must be spread and sprinkled with water before pressing. When it is evenly wetted, strain it and slowly operate the machine.
4. Press the felt before adding paper. Meanwhile, soften the polyamide fiber of felt surface with soda water to improve its adaptability.
5. Adopt the way of double-sides sprinkling to wash felt. Adopt high pressure (5~20kgf/cm2)moving sprinkling pipe to wash the reverse side; and adopt frequent pressure(1~3 kgf/cm2)fan sprinkling to wash the obverse side.
6. Strain the front side of standard line according to the operating direction; soften the back of standard line. Adjust a little once until finding standard line is level and straight.
