Decay after corona treatment of PLA film
문제 현상
The surface tension of PLA film decreases rapidly with time after corona treatment.
원인 분석
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.
해결 방법
Use higher corona power and treatment time; perform subsequent processing (printing, laminating) as soon as possible after treatment.
핵심 요약
PLA corona decays quickly, and the production rhythm needs to be reasonably arranged.
