PS Product Solvent Cracking
문제 현상
After contact with solvent, spider-web-like cracks appear on the surface.
원인 분석
PS has poor solvent resistance; when internal stress exists, solvents induce environmental stress cracking; printing inks and adhesives are common media.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
해결 방법
①Reduce internal stress; ②Select compatible inks and adhesives; ③Avoid contact with strong solvents; ④Perform compatibility verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Solvent management for PS must run through material selection and post-processing; compatibility verification is indispensable.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
