PVB Pre-pressing Venting
ظاهرة المشكلة
PVB pre-pressing (roller pressing) venting is insufficient, residual air forms bubbles after lamination.
تحليل الأسباب
PVB pre-pressing roller pressing venting function; roller pressing speed, temperature, and pressure; glass and PVB lamination; edge sealing timing.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
الحل
①Roller pressing speed, temperature, and pressure optimization; ②Venting sufficiency verification; ③Lamination quality inspection; ④Edge sealing control.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
الخلاصة الأساسية
PVB pre-pressing venting is the key process for bubble prevention; parameter matching affects the effect; verification means ensure quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
