The Decisive Role of Forming Fabric in Paper Production
How do the structure and air permeability of a forming fabric influence fiber distribution, dewatering performance, machine speed, and operating costs? and introduce the selection of forming fabric for different types of paper.
Forming Fabric Installation Preparation and Subsequent Adjustments
About installation preparation, gradual commissioning, and in-service care of forming fabric, highlighting how tension control, alignment, and cleaning affect service life, drainage efficiency, and run stability.
How Press Felt Performance Affects Paper Quality and Production Cost
About the role of press felt in papermaking, how its design, surface condition, and operational handling affect drainage behavior, paper formation quality, energy efficiency, and overall machine performance.
Slurry Penetration and Rewetting in Press Felt
About three common press felt problems: steam spots, slurry penetration, and rewetting. Understand why each issue happens, how it affects paper production, and what actions can fix it.
Causes and Analysis of Dryer Fabric Vibration
Dryer fabric flutter can disrupt paper stability in paper machine. Regarding the differences in the effects of airflow, mesh layout, and single wire versus double wire drying on paper stability.
What Causes Forming Fabric Breakage During Paper Making?
Frequent wear on forming fabric can shorten service life and disrupt paper formation. Typical damage modes and operational factors affecting fabric durability are described.
Dryer Fabrics Replacement and Installation Matters
Regular dryer fabric replacement is essential in papermaking. High heat, pulp, and chemicals cause fouling and wear, cutting drying efficiency and paper quality.
Reasonable Use of Alkali and Acid Washing for Press Felts
Press felt cleaning is crucial for dewatering efficiency, paper quality, and the life of the press felt itself. The main cause of the contamination is blockage by fiber fillers, slurry, resin and other impurities. Appropriate alkaline and acid washing can remove deposits and improve the dewatering efficiency of press felt.
Impact of Dryer Fabric Contamination and Cleaning Methods
Dirty on dryer fabrics can reduce paper quality and machine efficiency. Sun Hong will introduce various dryer fabrics cleaning methods to maintain air permeability and extend its service life.
