Decay after corona treatment of PLA film
Sorun Belirtisi
The surface tension of PLA film decreases rapidly with time after corona treatment.
Neden Analizi
The migration of surface active segments of PLA causes the corona effect to decay rapidly; the corona energy is insufficient and the treatment is inadequate.
Çözüm
Use higher corona power and treatment time; perform subsequent processing (printing, laminating) as soon as possible after treatment.
Temel Çıkarım
PLA corona decays quickly, and the production rhythm needs to be reasonably arranged.
