MBS core-shell structure destroyed during processing
ظاهرة المشكلة
MBS core-shell structure is destroyed during processing, and the toughening effect is completely lost
تحليل الأسباب
Processing temperature too high, exceeding the 180-220°C upper limit, causing rubber core melting
Excessive screw shear destroys the core-shell interface
Mixing time too long, core-shell structure repeatedly stressed and destroyed
Screw compression ratio too large
Improper MBS model selection, fragile core-shell structure
الحل
Strictly control processing temperature not exceeding the 180-220°C upper limit
Reduce screw rotation speed to reduce shear
Shorten mixing time
Select a low compression ratio screw
Select MBS models with stable core-shell structure
الخلاصة الأساسية
MBS core-shell structure needs gentle processing conditions for protection
