Polymer testing equipment conforms to GB/T9643, GB/T3682, JB/T5456, ISO1133 standards, in accordance with GB/ t3682-2000, ASTM D1238-98 standards, and refer to JB/T5456, ISO1133 and other similar standards for the measurement of thermoplastic melt volume flow rate (MFR) instrument, determination of melt mass flow rate using automatic sampling, balance weighing method;Then calculate the volume flow rate according to the formula.The final result of the measurement is displayed on the liquid crystal screen of the instrument and output by the micro-printer.
It is suitable for the determination of polyethylene (PE), polypropylene (PP), polyformaldehyde (POM), polystyrene (PS) ABS resin, polycarbonate and other plastics with lower melting temperature.Widely used in plastic production, plastic products, petrochemical and other industries and related colleges and universities, scientific research units, commodity inspection departments.
1. The product is controlled by PLC and displayed on the LCD screen: time, temperature and sampling times.
2. Measurement by mass method (MFR) has high accuracy and accurate data.
3. Volume method
