PCL low-temperature impact modification
Fenómeno del problema
PCL as a low-temperature impact modifier for plastics, effect and compatibility.
Análisis de la causa
PCL low-temperature toughness; compatibility with matrix; modification effect; addition amount; cost-effectiveness.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Compatibility assessment; ②Addition amount optimization; ③Low-temperature testing; ④Cost analysis; ⑤Application verification.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Compatibility and effect of PCL low-temperature modification are the core; tests verify performance improvement; cost decides application.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
