A, melt flow rate meter USES:
XNR - 400 - b type melt flow rate meter was used to characterize the properties of thermoplastic polymer in the state of viscous flow instrument, used to determine the melt quality of thermoplastic resin flow rate (MFR) and the melt volume flow rate (MVR), it is suitable for high melting temperature of polycarbonate, nylon, fluorine plastic, aromatic alum engineering plastics, also applies to polyethylene, polypropylene, polystyrene, poly formaldehyde resin, ABS resin with lower melting temperature, such as plastic test, widely used in petroleum chemical industry, plastic raw materials, plastic production, plastic products and other industries and related testing departments, scientific research units, colleges and universities.
Second, the melt flow rate meter features:
XNR - 400 - b type melt flow rate meter is based on national standard and international standard design and manufacture, has the advantages of simple structure, convenient operation, easy maintenance, etc.The instrument has digital temperature display, time can carry out quality standard test, has the time control and manual ways for blanking, temperature can be automatically calibrated.
Three, melt flow rate meter standard:
GB/T 3682 "thermoplastics melt mass flow rate and melt volume flow rate measurement,
ISO 1133 plastic - thermoplastics melt mass flow rate and melt volume flow rate measurement,
JB/T 5456 "melt flow rate instrument technical conditions"
Four main technical parameters, melt flow rate meter:
The power supply voltage is AC220V plus or minus 10% 50 hz
Maximum power 750 w
Cylinder at room temperature to 450 ℃ temperature range
Temperature control of error of plus or minus 0.2 ℃ (discharging mouth top 10 mm)
Displacement measurement error is 0.2 mm / 3 mm
Temperature display resolution 0.1 ℃
Cylinder bore ￠9.550 + / - 0.025 mm
The piston ￠9.475 + / - 0.015 mm in diameter
The piston head length 6.350 + / - 0.100 mm
Standard mouth mold ￠2.095 + / - 0.005 mm
Standard mouth mould height 8.000 + / - 0.025 mm
Test load / 2.16/3.8/0.325/1.2 5/10/12. 5/21.6 kg
So-called melting body mass flow rate is refers to the extrusion of paragraphs sample weight is reduced to an average of 10 minutes of extrusion.Unit (g / 10 min), expressed with MFR L
MFR = 600 x m present t
Type: MFR - melt mass flow rate, g / 10 min;
M - for many period of the average of the sample, g.
T - sample interval, s;
600 - reference time (10 min), s
The melt flow rate meter weight list as follows:
