DSTDP internal unmelted particles
Problem Phenomenon
DSTDP product interior shows unmelted transparent or semi-transparent particles
Cause Analysis
Screw plasticizing capacity insufficient, temperature on the low side; feeding amount too large, exceeding plasticizing capacity; DSTDP melting temperature on the high side
Solution
1) Raise processing temperature to ensure full melting; 2) reduce feeding amount to match plasticizing capacity; 3) increase screw mixing section
Key Takeaway
Unmelted particles are caused by insufficient plasticization; raising temperature and reducing feeding are key
