Plastometer is used to test the quick plasticity value (P0) and plasticity retention ratio (PRI) of natural rubber and unvulcanized plastics (blends).
Rapid plasticity meter is used to test the rapid plasticity value (P0) and plasticity retention ratio (PRI) of natural raw and unvulcanized plastics (blends).This instrument is composed of a main machine, a blanking machine (including a cutting knife), a high-precision aging test box, a thickness gauge and other parts.The rapid plasticity value P0 is rapidly compressed by the main engine from the cylindrical sample between two parallel pressing blocks to a fixed thickness of 1mm. The tested sample is kept in a state of compression for 15s to achieve the temperature balance with the parallel plate. Then the sample is applied with a constant pressure of 100N 1N and maintained for 15s.At the end of this phase, the test thickness measured by the instrument is used as a measure of plasticity.
Plastic retention PRI through high precision special the sample ageing oven at temperature of 140 ° after aging for 30 min, P30 plastic value is measured, calculated the PRI values.PRI value is a measure of heat resistance of natural raw rubber. Higher PRI value indicates better heat resistance and oxidation performance.
Rapid plasticizer adopts Wallace new technology, advanced technology and stable performance.The machine adopts electronic direct temperature control, rapid temperature rise, high precision, and the machine USES standard weights to load directly, which overcomes the disadvantages of instability and zero drift caused by the load of electromagnetic spring pressure.Wallace update products with synchronization, in the leading position at home and abroad.
