چکیده انگلیسی
In order to obtain more accurate prediction of the service performance and service life of polymers and the optimization of processing parameters, this paper presents a novel, on-line testing equipment for measuring P-V-T (Pressure-Volume-Temperature) relationships of polymers under processing conditions. This equipment is based on an injection molding machine (IMM), and it can be used to get P-V-T data of polymers directly with a special testing mold under normal processing conditions. P-V-T properties of five polymers (ABS, PS, LDPE, PA 6 and PP) were measured. The experimental results under industrial processing conditions were presented. The results were compared with those obtained by the confining fluid technique. The P-V-T curves were consistent, which proved that the new on-line measurement is feasible. The repeatability of the P-V-T measurement was within 0.3%. Consequently, a new P-V-T database on typical commercial materials could be established. Repeatability of IMM could be improved significantly.
