Tissue production relies on a delicate balance: the paper web must adhere firmly to the Yankee dryer for efficient drying and creping, yet release smoothly without sticking or causing sheet breaks. An improperly selected or applied cylinder adhesive agent disrupts this balance, leading to poor creping, paper flutter, web breaks, and reduced machine efficiency.
PR-09 Cylinder Adhesive Agent from Luterra Advanced Materials is a waterborne polymer solution formulated from polyamide that crosslinks at Yankee dryer operating temperatures. It regulates coating build-up, protects the dryer, improves heat transfer, and ensures "moderate adhesion" for optimal creping and release. This guide covers five critical mistakes to avoid when using a cylinder adhesive agent.
Mistake #1: Choosing an Adhesive That Doesn't Provide "Moderate Adhesion"
Some adhesives create excessive bonding, making the paper difficult to release from the dryer and causing sheet breaks. Others provide insufficient hold, leading to paper slippage, flutter, and poor creping.
PR-09 achieves "moderate adhesion" through precise control of the adhesive film's thickness and strength. It ensures the paper web does not slip during creping while still releasing smoothly from the dryer with the help of a release agent. By adjusting the dosage and the ratio with release agent, it can flexibly meet the requirements of different paper grades and machine speeds.
Mistake #2: Using a Product Incompatible with Your Release Agent
The cylinder adhesive and release agent must work in harmony. An adhesive that conflicts with your release agent disrupts the coating balance, leading to uneven adhesion, poor creping, and increased downtime.
PR-09 is designed to be part of a balanced coating system. When used with a compatible release agent, it delivers consistent performance. The adhesive keeps the paper adhered to the dryer, while the release agent ensures smooth detachment-enabling stable, high-speed tissue production.
Mistake #3: Overlooking the Adhesive's Impact on Heat Transfer
The adhesive coating on the Yankee dryer is not just about adhesion-it also affects heat transfer from the dryer to the paper web. A poorly formulated adhesive can act as an insulator, reducing drying efficiency and increasing energy costs.
PR-09 forms a thick coating that protects the dryer and improves heat transfer between the dryer and the paper web. This ensures efficient drying, which is critical for high-speed tissue machines and maintaining product quality.
Mistake #4: Ignoring Safety Standards for Tissue Applications
Tissue papers used in food-contact, consumer, and hygiene applications must meet strict safety standards. Using an adhesive that doesn't comply can disqualify your entire production.
PR-09 complies with hygiene standards for food and consumer products, making it suitable for various tissue papers. This ensures your production meets regulatory requirements while maintaining performance.
Mistake #5: Not Optimizing the Adhesive/Release Agent Ratio for Your Specific Grade
Different tissue grades and machine speeds require different adhesion levels. Treating the dosage as fixed leads to suboptimal creping, quality issues, or runnability problems.
By adjusting the dosage and the ratio with release agent, PR-09 can flexibly meet the requirements of different paper grades and machine speeds. Start with the recommended dosage and fine-tune based on actual creping performance and sheet quality.
