PS Product Solvent Cracking
Problembeschreibung
After contact with solvent, spider-web-like cracks appear on the surface.
Ursachenanalyse
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
Lösung
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
Wichtigste Erkenntnis
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
