Hypothesis
The addition of lignin to thermoformed pulps will reduce water absorption and improve material properties.
Conclusion
The study found that adding acetylated lignin significantly reduced water uptake and improved the stiffness and strength of certain pulp types.
Supporting Evidence
- The dataset shows slight increases in density after lignin addition.
- On average, water absorption was reduced with lignin addition.
- Adding acetylated lignin significantly lowered water uptake compared to regular lignin.
- CTMP showed the same or lower tensile strength after lignin addition.
- NBSK showed increases in both stiffness and strength after lignin addition.
Takeaway
This study shows that adding a natural substance called lignin to certain types of pulp can make them better at resisting water and stronger overall.
Methodology
The study involved creating pulp-lignin composites through wet-forming, pressing, and tensile testing to measure their properties.
Limitations
No obstacles were encountered during the sample preparation and analysis.
