PVB Uneven Crosslinking Gel Particles
Sorun Belirtisi
Gel particle defects appear in PVB film, uneven crosslinking causes some resin to be difficult to plasticize.
Neden Analizi
PVB resin crosslinking controllability is not strong, agglomeration easily occurs during synthesis; uneven crosslinking makes some resin difficult to plasticize during extrusion and produces gel particles; particle uniformity, haze, and light transmittance are affected.
Çözüm
①Select uniformly crosslinked PVB resin; ②Particle uniformity inspection; ③Extrusion process optimization for plasticization; ④Gel particle detection and screening.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
PVB gel particle defects originate from resin synthesis quality; crosslinking uniformity is a key raw material indicator; detection and screening ensure optical quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
