Blend Modification of PLA Products
Problem Phenomenon
Pure PLA performance is unsatisfactory.
Cause Analysis
Blending can improve brittleness and toughness but compatibility is a challenge; compatibilizer selection and degradability retention need to be balanced.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Select compatible blend systems; ②Add compatibilizer; ③Verify degradability retention; ④Systematically optimize the formula.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA blend modification is the main path for performance improvement; compatibility and environmental friendliness must both be considered.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
