Melt Flow Rate Testing Instrument for Plastic Material Flow Rate
Analysis and Evaluatio
Operating Principle:
Melt Flow Rate Testing Instrument for Plastic Material Flow Rate
Analysis and Evaluatio is a plastic extruder. It works under the
specified temperature to melt the sample by using heating furnace.
The melted sample flows out a specified hole under the given load.
In plastic producing activities, we usually use the melting index
to, under melted state, measure the physical properties of the
polymer, such as the fluidity, the mucosity and so on. The
mass-flow rate MFR is the average mass of substance which passes
through a given surface per 10 minutes. The unit is (g/10min),
Denoted by MFR, which is defined as
MFR=600×m÷t (1)
Where
MFR The melt mass-flow rate of material, unit g/10min;
m Average mass, unit g;
t Time interval, unit s;
600 Reference time (10 min), unit s.
MFR Example
There is a group of plastic samples which are cutted per 30
seconds. The weights are 0.0838 g, 0.0862 g, 0.0815 g, 0.0895 g,
0.0825 g respectively.
The average weight, m=(0.0838＋0.0862＋0.0815＋0.0895
＋0.0825)÷5=0.0847 g
Substituting into the equation, we have
MFR=600×m÷30=1.694(g/10min),
So that the MFR is 1.694g/10min.
