Risk of Blending PVDF with Other Fluoroplastics
Sorun Belirtisi
【Problem Phenomenon】When PVDF is blended and modified with other fluoroplastics, phase separation and delamination occur with uneven performance
Neden Analizi
PVDF has limited compatibility with most fluoroplastics; phase separation occurs when blending ratio and shear mixing do not match; blending modification must be based on compatibility data; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Çözüm
Check compatibility literature and supplier data before blending; verify the phase structure in small-scale tests before scaling up; add compatibilizer and optimize the mixing process if necessary; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
For fluoroplastic blending, compatibility comes first; phase-separating formulations must not be forced through; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
