ABS back pressure 5-15MPa
Sorun Belirtisi
ABS back pressure 5-15MPa, balance of mixing and shear heat, high back pressure degradation.
Neden Analizi
ABS back pressure 5-15MPa; high back pressure improves melt uniformity; but shear heat accumulates; butadiene rubber phase degradation; screw speed 40-70rpm coordination; temperature monitoring.
Çözüm
①Back pressure 5-15MPa; ②screw 40-70rpm; ③shear heat monitoring; ④rubber phase protection; ⑤actual melt temperature measurement.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
The coordination of ABS back pressure and screw speed is plasticization quality; shear heat management protects the rubber phase; actual measurement prevents deviation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
