XNR-400A Plastic Melt Flow Index Tester / MFI Tester
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
Application:
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.
Main Technical Data:
(1) Specimen outlet part:
Outlet diameter: Φ2.095±0.005mm
Outlet length: 8.000±0.025mm
Screw barrel internal diameter: Φ9.550±0.025mm
Screw barrel length: 152±0.1mm
Diameter of piston-rod head: Φ9.475±0.015mm
Length of piston-rod head: 6.350±0.100mm
(2) Test load (Eight grades):
The test load is determined by a piston rod combined with a set of
weights. There are eight grades of loads in total. The weight error
of the cylinder rod and combined weight is no more of +/- 0.5%.
(3) Temperature range: Room temperature ~400.00℃
(4) Temperature control resolution: ±0.5℃
(5) Overall dimension: 290*450*630mm(L*W*H)
Working Conditions:
(1) Temperature 10℃ ~35℃, relative humidity 30%-80%; no vibration,
no corrosive media around.
(2) Solid base, correct installation, and horizontal position.
(3) No strong magnetic field interference and no strong convective
air.
(4) Power supply: AC220±10%, 50Hz. The voltage fluctuation should
not exceed ±10% of the rated voltage.
