PVC Filler Agglomeration
Sorun Belirtisi
Highly filled PVC products have surface powdering and low strength
Neden Analizi
Fillers such as calcium carbonate are poorly dispersed and agglomerated, with weak interfacial bonding; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry materials, and it should be confirmed first during troubleshooting
Çözüm
Filler content control; coupling agent treatment of the filler; assurance of mixing uniformity; After adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes, so as to locate effective measures
Temel Çıkarım
High filling relies on dispersion and interface treatment; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a reference for troubleshooting similar problems in the future
