摘要

The effect of pan-milling on morphological structure

processability and properties of PVC was studied through SEM

FTIR

granulometer

GPC and mechanical properties test in the hope of gaining ease in operation

needless of plasticizers

a clean and efficient route for improving the processability of PVC through stress-induced reactions

fulfilling the idea of “plasticizing PVC by itself”. The experimental results show that during pan-milling at ambient temperature

within 2-3 min

the microcrystalline structure of PVC becomes indistinct

the grain size of PVC is reduced from 130-160 mm to 1-50 mm

the molecular weight of PVC is slightly decreased

the variation of molecular weight distribution is indistinct

the plasticizing time and torque at balance drop a great deal from 71-132 s to 31-33 s and from 18.2-22.1 Nm to 14.7-18.4 Nm

respectively

the processability of PVC is markedly improved

and the mechanical properties get enhanced too.
