XNR-400B Liquid-crystal display plastic melt flow index tester
General introduction
XNR-400B Melt Flow Indexer is an instrument used to indicate the
MFR and the MVR of thermoplastic plastic, which is designed and
produced according to the standards like GB/T3682-2000, ASTM
D1238-98, JB/T5456, ISO1133, etc. When measuring MFR, the specimen
is cut automatically, the time interval of cutting specimen is
controlled by PLC and the weight is measured by the balance. When
measuring MVR, with the displacement measured through photoelectric
encoder and the time measured automatically, the needed time for
the piston to move a required distance is measured first and the
MVR could be figured out through the formula. Both of the results
of MFR and MVR will be displayed on the LCD screen and printed out
by the micro-printer. The measured data is very accurate, the
operation is very easy, and the performance is very stable. It is
adequate for not only engineering plastics with high melting
temperature such as polycarbonate, fluoroplastic, and nylon, but
also the plastics with low melting temperature such as
polyethylene, polypropylene, polystyrene, ABS resin and
acetaldehyde resin. It is widely used in plastic production and
petrochemical industry, and also in related institutions, research
units and commodity inspection department.
Application:
XNR-400B Melt Flow Index Tester is accordance to ISO1133;GB3682
2000,ASTM D1238.
It's suitable to measure melt flow character of PP, PE, POM, ABS
plastics and plastic
productions, widely used in factories, products quality testing
station, scientific and research
institutes, and concerned industries.
