XNR-400 Used melt flow index tester/melt flow index test instrument
Principle
Melt flow rate instrument is a kind of extrusion plastic meter, it is stipulated in the temperature of analyte with high temperature furnace molten state, the molten state of the measured object, under the specified load through the regulation of the diameter of the pores (standard orifice) extrusion experiment was carried out.Melt flow rate is refers to the thermoplastic (materials) under certain temperature and pressure, melt every 10 min by specifying exactly the quality of the standard orifice.
Melt flow rate with MFR, said its unit is: g / 10 min.
Features:
XNR - 400 type melt flow rate instrument is in accordance with ISO1133, ASTM D1238, ASTM D3364 standards of design and manufacture for the determination of thermoplastic plastics melt flow rate (MFR) of the instrument, is the basic instrument of such series products produced by our company, has the advantages of simple structure, convenient use, accurate measurement data, the performance is stable and reliable, economical and practical etc. using intelligent temperature instrument control of constant temperature, fast, high precision. The timing unit adopts intelligent timer, accurate timing. This instrument is not only applicable to the high melting temperature of polycarbonate, fluorine plastic, nylon engineering plastics test, also suitable for polyethylene, polypropylene, polystyrene, ABS resin melting temperature low plastic test, widely used in plastics, plastic products, petroleum and chemical industries, relevant institutions, scientific research units, the commodity inspection department.
