How to Improve the Quality of Corrugated Cardboard Production:

1. Optimize Raw Material Selection

   • Pulp Quality: Select pulp with high strength and fiber content to form the basis of corrugated cardboard, ensuring its robustness and durability.
   • Adhesive Quality: Utilize high-quality starch adhesive or alternative suitable adhesives to guarantee strong and secure bonding within the cardboard. For instance, our automated glue kitchen, controlled by a sophisticated system, produces top-notch adhesive tailored to specific production orders, materials, temperatures, and climates, thereby facilitating the production of premium-quality cardboard.

2. Strengthen Production Process Control

   • Moisture Control: Maintain stringent control over moisture levels during production to ensure optimal humidity conditions, preventing deformation or fragility due to improper moisture levels. Our newly installed preheater, equipped with temperature sensors and steam valves with a spray system, fine-tunes paper moisture and reinforces paper fibers.
   • Temperature Control: Regulate the working temperature in key production stages, such as preheating cylinders and single-sided machines, to ensure thorough preheating and shaping of the cardboard.
   • Pressure Control: Apply reasonable pressure during corrugating and gluing processes to avoid crushing the corrugations or damaging the cardboard.

3. Upgrade Production Technology

   • Adopt Digital and Intelligent Equipment: Incorporate advanced digital and intelligent machinery to enhance production precision and efficiency. Opt for high-quality production lines with state-of-the-art control systems to achieve optimal cardboard production.
   • Optimize Production Process: Implement precise control over the production process, particularly in critical steps like rib forming and reinforcement layer placement, ensuring precision and error-free operations.
   • Innovate Production Processes: Develop new techniques, such as utilizing multi-layer core paper structures, to boost cardboard strength at the same weight while reducing thickness for easier transportation and storage.

4. Enhance Cardboard Performance

   • Add Reinforcing Agents: Introduce wet strength agents, dry strength agents, and other reinforcing additives to pulp to bolster fiber bonding and overall cardboard strength.
   • Moisture-Proofing Treatment: Apply moisture-proofing agents or treatments to the cardboard surface during production to enhance its resistance to moisture.
   • Mold-Proof Treatment: In humid environments, regularly dry the cardboard or incorporate anti-mold additives to prevent mold growth.

5. Strengthen Quality Inspection and Maintenance

   • Regular Inspection: Conduct thorough quality checks on cardboard on the production line to ensure it meets specified standards.
   • Equipment Maintenance: Regularly maintain and service production equipment to ensure smooth operation and minimize downtime.
   • Inventory Management: Properly manage corrugated cardboard inventory to prevent prolonged exposure to adverse conditions, such as humidity, that could compromise its quality.
