PVB Surface Defects
Sorun Belirtisi
Contamination, die lines, and gel particles appear on the PVB film surface, transparency and quality decline.
Neden Analizi
Contamination, die lines, or gel particles affect transparency and quality; raw material impurities; die surface condition; poor plasticization produces gel; environmental cleanliness.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Çözüm
①Raw material purity management; ②Regular die surface cleaning and polishing; ③Plasticization system optimization; ④Production environment cleanliness control.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
PVB surface defect prevention covers raw materials, equipment, and environment; transparency is the core of optical applications; cleanliness management is a system engineering.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
