Automatic Melt Flow Rate Tester
Model: MAM-08E
Introduction:
This is a high-precision automatic melt flow rate meter tester, used to determine the temperature and load of various plastics and resins when they pass a certain temperature and load in a viscous flow state. It passes through the standard die melt flow rate MFR/MVR value every 10 minutes. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, nylon, etc., which have higher melting temperatures. It is also suitable for polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, poly Formaldehyde (POM), polycarbonate (PC) resin and other low melting temperature plastic testing are widely used in plastic production, plastic products, petrochemical industries and related universities, scientific research units and commodity inspection departments.
Standards:
GB/T3682-2000
Thermoplastic melt flow rate and melt volume flow rate determination
ISO 1133: 1997
Thermoplastic melt mass flow rate MFR and melt volume flow rate MVR measurement
ASTM D1238
Standard Test Method for Measuring Thermoplastic Melt Flow Rate by Extrusion Plastometer
Advantages:
1. Power supply voltage: AC220V±10% 50HZ
2. Multi-section (5 sections) temperature control mode, 5 groups of platinum resistance sensors, 5 heating jackets for individual temperature control, high-precision intelligent PID control, the heating slope, that is, the heating speed can be adjusted
3. The temperature resolution is 0.1°C, the temperature uniformity is 0.2°C, the temperature fluctuation within 24 hours does not exceed 0.5°C, and the displacement sensor resolution is 0.001mm.
4. Temperature over-temperature protection device
5. Manual automatic cutting is integrated, and the cutting time (0~999) and the number of cutting times (0~999) can be set arbitrarily
6. When testing, you can choose the mass method, or volume method, or two testing methods at the same time, and the flow rate ratio can be calculated. In both methods, the test is started when the piston rod moves to a certain position.
7. Built-in temperature stabilization warning alarm, and add 240 seconds (GB3682 regulations) material warm-up seconds countdown, after the countdown is over, a beep will sound, and the American standard (ASTM) warm-up time can also be set.
8. Built-in a variety of plastic material melt index test conditions, convenient for customers to call and use at any time, reduce tedious workload, and store the last test conditions and results
9. Built-in micro printer for easy printing of test data
10. High-precision touch screen controller, 4.3-inch touch screen, can store and print the latest test conditions and data, the test print menu settings include test time (system default), operator, material name, test method, test conditions (temperature, weight) Weight, cutting time interval), test result data, test result artificial judgment OK or NG, etc.,
11. The RS232 interface or USB interface is reserved to connect to the computer, and the operation of the instrument can be controlled through the computer and the test data can be transferred and saved to the computer.
12The weight can be loaded manually or the ball screw can be driven to rotate by a stepper motor to achieve the purpose of automatically controlling the rising or falling of the top loading weight
