To give full play to the performance of papermaking forming mesh and extend their service life, it is necessary to systematically advance the work from three dimensions: forming fabric selection, process optimization and intelligent management. Through continuous technological innovation and refined operation and maintenance, we can effectively improve paper quality, reduce overall costs, and promote the development of papermaking production towards an efficient, green and sustainable direction.
The following are the specific operational key points and maintenance specifications to achieve the above goals:
I. Guarantee of Equipment Condition and Installation Accuracy
Ensure that all components of the fourdrinier wire table are accurately aligned and in good mechanical condition. All dewatering elements must be securely fastened and maintained at the same horizontal level.
Regularly inspect the tension roll and automatic tension adjustment device to ensure stable operation without abnormal bouncing.
II. System Cleaning and Daily Maintenance
Insufficient wire table cleaning and daily maintenance is often the main cause of shortened forming fabric service life.
(a) Prevention of Fiber Accumulation
Strictly prevent fibers from accumulating and forming pulp lumps, which may fall into the inner side of the forming fabric and cause abrasion.
(b) Doctor Blade Maintenance and Management
(c) Waterway and Spray System Inspection
Regularly check whether the water receiving trays are damaged, whether the bolts are rusted, and whether the spray valves are functioning properly. Uneven water flow may cause metal debris to peel off and block the spray pipes.
III. Process Optimization and Key Parameter Control
Avoid using abrasive fillers as much as possible.
Regularly inspect and calibrate the fabric’s running track, tension, load and slippage status. Ensure uniform transverse tension of the fabric on the paper machine and prevent operation under excessively loose conditions.
Maintain the temperature and pH value of the spray water consistent with those of the pulp, and ensure that the clean water spray pipes on both sides are unobstructed.
Effectively use centrifugal cleaners and other equipment to remove coarse sand from the pulp. Regularly inspect the contact surfaces of forming boards, suction box panels, table rolls, etc., and remove scratches and burrs.
IV. Special Maintenance and Auxiliary Measures
Consider using forming fabric life extenders (fabric cleaners) to improve operating conditions.
Ensure that the drive system provides appropriate surplus traction to prevent fabric slippage at the breast roll.
Check the installation position of the forming boards to ensure uniform and minimized sufficient space for breast roll drainage.
Keep the fabric roll turning system clean.
Regularly check the wear condition of the edge positioning devices or headbox cheeks, and confirm that they do not rub against the fabric surface due to excessively low installation.
