Wet-End Stability-Tissue
Stabilize the headbox and loops to improve softness/yield, reduce sheet breaks and steam consumption.
Customer Challenge / Issue
In tissue papermaking, maximizing yield while reducing drying energy is a major challenge. Excessive moisture before Yankee increases energy consumption, slows production and impacts final paper quality (strength, softness, creping ability). A poorly optimized wet end also compromises machine stability, leading to more breakage and material lossesForme
Axchem Solution
To minimize energy consumption, Axchem has a range of products that will help to reduce the moisture content before the yankee. Our chemicals solutions improve the retention of fibers, fillers and additives, while promoting rapid drainage to lower moisture before drying.
Depending on requirements, we adjust the chemistry to achieve the best balance between retention, dry/ wet strength and de-aeration.
At the same time, our products help reducing flash breaks, developing creping flexibility and increasing softness.
Benefits
To enhance energy efficiency and overall machine performance, several technical solutions can be implemented at different stages of the production process.
First, reducing moisture before the drying phase leads to significant energy savings. AXFLOC® retention and drainage aids improve water removal in the forming section, thereby lowering the thermal load on drying cylinders.
Next, machine speed and process stability can be improved through the combined use of AXFLOC® and AXFIX®. AXFLOC® enhances sheet formation and consistency, enabling higher operating speeds, while AXFIX® effectively controls both organic and inorganic deposits, reducing downtime and improving operational reliability.
In addition, the development of dry and wet strength is supported by the AXSTRENGTH® range, which includes anionic, cationic, and amphoteric polymers. These additives strengthen fiber bonding, making them ideal for printing, packaging, and tissue applications.
