Large fluctuation of PVA impact strength
Fenómeno do problema
PVA product impact strength fluctuates ±30%, unstable
Análise das causas
PVA dispersed phase particle size fluctuates 0.2-1μm causing unstable toughening effect; crystallinity fluctuation affects impact
Solução
1) Stabilize processing conditions to ensure consistent dispersed phase particle size; 2) Nucleating agent to control crystallinity; 3) Raw material batch consistency control
Conclusão principal
Impact fluctuation is caused by unstable dispersed phase and crystallization; stable processing is the key
