Melt flow rate meter using automatic sampling, balance weighing method, according to the formula to determine the volume of thermoplastic melt flow rate (MFR)

Test criteria:
ISO 1133, ASTM / D1238-98, GB / T3682, GB / T9643, GB / T3682, JB / T5456, ISO1133, GB / T3682-2000

Applications:
(PE), polypropylene (PP), POM (POM), polystyrene (PS) ABS resin, polycarbonate and other low melting temperature of the plastic Determination. Widely used in plastics, plastic products, petrochemical industry and related universities, research institutes, commodity inspection departments.

Detection principle:
Plastic melt index instrument, also known as melt flow rate meter, is a plastic extrusion device, the measured thermoplastics placed in the cylinder of the instrument, as early as the temperature, with a furnace to reach the molten material, and The extrudate is converted to the melt by mass flow MFR (G / 10MIN) of the standard die every 10 minutes or the extrudate is converted into a melt 10 minutes through the standard die volume flow MNR (CM3 / 10MIN), with the measured object in the molten state of the mobility, viscosity and other physical properties.

Test load:
Level 1: 0.325kg = (+ piston + weight tray body weight insulating jacket number +1) = 3.187N
Level 2: 1.200 kg = (0.325 + 2 0.875 weight) = 11.77N
Level 3: 2.160 kg = (0.325 + 3 1.835 weight) = 21.18N
Level 4: 3.800 kg = (0.325 + 4 3.475 weight) = 37.26N
Level 5: 5.000 kg = (0.325 + 5 4.675 weight) = 49.03N
Level 6: 10.000 kg = (0.325 + 5 4.675 5.000 + 6 weight number weight) = 98.07N
Level 7: 12.500 kg = (0.325 + 5 4.675 5.000 + 6 + weight No. 7 2.500 weight) = 122.58N
8: 21.600 kg = (0.325 + 2 0.875 weight +3 1.835 + 4 3.475 + 5 No. 4.675 + 6 5.000 + 7 2.500 + 8 2.915 weight) = 211.82N
The relative error of the test load is less than or equal to 0.5%.
