ظاهرة المشكلة
【Problem Phenomenon】Need weather-resistant sheets with higher surface hardness and gloss
تحليل الأسباب
PMMA/ASA co-extruded sheet combines PMMA's high hardness and high gloss with ASA's toughness and weather resistance; advertising and sanitary sheets commonly use this structure; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
الحل
High surface requirements choose PMMA/ASA co-extruded sheet; surface PMMA layer provides hardness and gloss; note PMMA layer brittleness, prevent cracking during processing; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
الخلاصة الأساسية
PMMA/ASA co-extruded sheet, hardness, gloss and toughness all wanted; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
