Overview
This melt flow rate meter is an improved model, which has significantly improved the instrument configuration, service life, operation convenience and test accuracy, and has very good advantages and cost performance. The instrument is a desktop structure with reasonable design, stable and reliable performance, beautiful appearance and easy operation. It is suitable for measuring the melt flow rate MFR value of various plastics and Resin in viscous flow state.
Features
1. The heating cylinder is made of Hastelloy, which is resistant to high temperature and oxidation and prolongs the service life.
2, Dual Sensor configuration, accurate temperature control, good temperature layer, longer life.
3. According to the requirements of the national standard, add a four-minute countdown function after feeding.
4. RS232 interface, can be directly connected to the computer to output data (optional).
5. After booting, the last test conditions can be directly displayed to reduce the workload of repeability settings.
6. Temperature can reach 450 to 500 degrees (optional).
7, can be long-term testing of corrosive plastics (such as all fluoroplastics) without damaging the instrument accuracy.
8. The heating speed is fast, and the overshoot is minimal.
9, high thermostatic accuracy.
10, can quickly restore the thermostatic state after filler.
11. The test parameters are calibrated and corrected conveniently.
12. Manual and automatic cutting test methods can be used.
13. Chinese LCD display.
14. Equipped with a printer, it can automatically print test results.
Principle
The instrument is based on the national standard "GB/T3682-2000 Thermal plasticity Plastics Determination of melt mass flow rate and melt volume flow rate", adopts high performance, High Accuracy control instrument, and conducts thermostatic control through fuzzy PID algorithm to determine the melt mass flow rate (MFR) or melt volume flow rate (MVR) of thermal plasticity plastics under specified conditions.
Applications
Plastic production, plastic products, Petrochemicals and other industries as well as related universities, R & D institutions and commodity inspection departments. Applicable to polycarbonic acid ester, polyaryl sulfone, fluoroplastics, nylon and other engineering plastics, as well as polyethylene (PE) (PE), polystyrene (PS), polypropylene (PP) (PP), ABS Resin, polyformaldehyde (POM), polycarbonic acid ester (PC) Resin and other low melting temperature plastic testing.
Standards
ISO 1133、ASTM D1238、GB/T3682
Steps
1. Turn it on and set the test parameters (or use the last test conditions).
2, wait for the heating cylinder to heat up to the set temperature and thermostatic.
3. Add the test materials.
4. Activate the four-minute countdown function.
5. According to the test requirements, choose manual or automatic cutting methods.
6. The instrument automatically calculates and displays the test results.
7. Output test results through a printer (or connect to a computer to output data through an RS232 interface).
Notice
If you need to test temperatures up to 450 to 500 degrees or highly corrosive plastics (such as all-fluoroplastics), special instructions are required when ordering.
* Stainless steel weight and volume measurement functions are optional.
* Power supply voltage within (220-15%~ 220 + 10%) VAC 50Hz before use.
Please pay attention to high-temperature parts during operation to avoid burns.
Regularly calibrate and maintain instruments to ensure test accuracy.
