PVB Winding and Packaging
Problem Phenomenon
PVB film winding is uneven, improper packaging causes moisture absorption and contamination, storage performance changes.
Cause Analysis
PVB winding tension control; packaging moisture-proof and contamination-proof; storage environment; automatic tension control system; transportation protection.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Automatic tension control winding; ②Moisture-proof packaging sealing; ③Storage environment temperature and humidity management; ④Transportation protection measures.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PVB winding and packaging is the last link of quality maintenance; moisture-proofing is the core; environmental management runs through storage and transportation.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
