Melt Flow Rate Tester 400A (MFR) Digital dispaly XNR-400A Melt Flow Rate Tester is suitable to determine the Melt-mass Flow Rate (MFR) of thermoplastics .It is designed according to ISO1133:1997 with simple structure ,precise accuracy and stable property .It is convenient to operate .The machine is suitable for not only the test for high temperature melt materials such as PC ,FI plastics ,nylon ,but also the test for low temperature melt materials such as PE ,PP ,POM ,PS and ABS .It is widely used in some industries such as plastics fabrication ,plastic goods and petrochemical industry ,college and university ,science and research institutes and commodity inspection departments . 1. Specifications (1) Extrusion section : Die diameter :?2.095±0.005mm Die length : 8.000±0.025mm Inner diamenter of cylinder : ?9.550±0.025mm Cylinder length : 152±0.1mm Diameter of land of piston : ?9.475±0.015mm Length of land of piston : 6.350±0.100mm (2) Test load It contains a set of weight and a piston composed of amount of weights with altogether eight grades . 1st grade : 0.325kg(guide rod +weight tray+ heat isolation sheath+ weight #1) =3.187N 2nd grade:1.200kg(0.325kg+2#0.875kg weight )=11.77N 3rd grade:2.160kg=(0.325kg+3#1.835kg weight)=21.18N 4th grade:3.800kg=(0.325kg+4#3.475kg weight)=37.26N 5th grade:5.000kg=(0.325kg+5#4.675kg weight)=49.03N 6th geade:10.000kg=(0.325kg+5#4.675kg weight+6#5.000kg weight)=98.07N 7th grade:12.500kg=(0.325kg+5#4.675kg weight+6#5.000kg weight+7#2.500kg weight)=122.58N 8th grade:21.600 kg=(0.325kg+2#0.875kg weight+3#1.835kg weight+4#3.475kg weight+5#4.675kg weight+6#5.000kg weight+7#2.500kgweight+8#2.915kg weight)=211.82N (3) Temperature range :ambient temperature ~400°C (4) Temperature control accuracy : ±0.5°C (5) Dimension :290(L) x410(W) x630(D)mm 2. Working conditions (1) Indoor temperature: 10°C—35°C without vibration and corrosive media in ambient. (2) It should be installed and adjusted to be level on stable foundation. (3) There should be no strong magnetic field disturbance and air convection when it runs. (4) Power voltage: AC110V, frequency 50Hz .The wave range of the power voltage shall not exceed ±10% of the rated voltage. III.Theory and Structure 1.Theory Melt Flow Rate Instrument is a kind of plastic extruder .It can make the sample melt through high temperature oven in stated temperature conditions. The melt sample can be extruded from a die under stated load from the weights .Melt Flow Rate is the mass that the melt sample of the thermoplastics passes through standard die every 10min under definite temperature and pressure . The Melt Mass Flow Rate (MFR) is expressed by g/10min .The equation is as following : MFR(?,Mnom)=tref xM/t Where : ?—test temperature ,°C Mnom—test load ,kg tref—reference time(10min),S(600s) M—the average mass of the cut sample strips,g t—sampling time interval ,s For example :a tested material ,the sample sections are cut every 30S,the mass is 0.0816g,0.0862g,0.0815g,0.0895g and 0.0825g respectively .The average mass of the sample is : M=(0.0816+0.0862+0.0815+0.0895+0.0825)/5=0.0843(g), So MFR=600x0.0843/30=1.686(g/10min) If you need the 110V-120V item,please kindly contact with us before purchasing.
