PVB Lamination Flowability Imbalance
Fenómeno do problema
Improper PVB flowability during lamination, too high causes flow-out and glue shortage, too low causes insufficient filling.
Análise das causas
Under relatively high lamination temperature, the film should soften with appropriate flowability to fill the space between glass; too much flowability causes edge film flow-out producing glue shortage; insufficient flowability causes incomplete filling; high-temperature modulus influence.
Solução
①PVB high-temperature modulus and flowability matching design; ②Lamination temperature and pressure program optimization; ③Edge sealing management; ④Flowability testing and verification.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Conclusão principal
The balance of PVB lamination flowability is the process core; high-temperature modulus is a material design parameter; edge management prevents glue shortage.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
