| Popis: | The polypropylene (PP) samples were prepared at different molding temperature and their properties and structures were studied. The nearby melting point extrusion and molten extrusion were used to mold PP samples. The tensile strength of PP samples with molding nearby melting point extrusion had a 20.46% increase compared with samples with conventional extrusion. The same phenomenon occurred in Vicat softening temperature and there was a 13.9% increase. Differential scanning calorimetry (DSC) showed the degree of crystallinity for samples by nearby melting point extrusion increased 2.74% compared with samples by molten extrusion. The nearby melting point extrusion molding was beneficial to refine crystalline grain and the results can be proved in XRD, DSC and SEM tests. |
