From Pulp to Product: Understanding Cardboard Production
2. The Birth of Cardboard: Transforming Pulp into Durable Paperboard
The Refining Process: Breaking Down Fibers
The journey from softwood or hardwood pulp to robust cardboard begins with refining. Here, the fibers of the pulp are subjected to a mechanical or chemical treatment that breaks them down into smaller, more flexible strands. Mechanical refining uses grinders to crush the fibers, while chemical refining employs chemicals like sodium hydroxide or sodium sulfide to dissolve the lignin that binds the fibers together. This process enhances the paperboard’s strength and bonding capabilities.
Mixing and Combining: Blending Raw Materials
Once the pulp has been refined, it is mixed with other raw materials to create the unique properties of cardboard. Additives like starch, rosin, and clay are added to improve strength, water resistance, and print quality. These materials are carefully proportioned to achieve the desired balance of properties.
Forming the Sheet: Creating the Base
The refined and mixed pulp is fed into a papermaking machine, where it is transformed into a continuous sheet of paper. Here, the pulp slurry is spread onto a wire mesh conveyor belt, allowing the water to drain away. The newly formed sheet is then pressed and dried to remove any remaining moisture.
Multi-Layered Architecture: Building Strength and Thickness
To achieve the desired thickness and strength, multiple layers of paper are bonded together using adhesives. These layers can vary in composition, with some containing recycled materials or different fiber types. The multi-layered structure provides dimensional stability, enhanced durability, and improved resistance to tearing.
