How to maintain the
Melt Flow Index Tester correctly?
The
Melt flow index tester is mainly used to test the uniformity of polymer flow rate of thermoplastic and other materials with low melt viscosity (flow rate between 0.15-50g / 10min). The equipment is designed in accordance with GB / 3682, iso1133:1997 and other thermoplastic melt flow rate test methods.
We found that good maintenance and correct operation habits have a direct impact on improving the service life of the electric
melt flow index tester.
1. The working environment and conditions of the melt index instrument shall fully meet the specified requirements, including room temperature, relative humidity, power supply voltage and installation foundation (generally, there shall be no vibration, corrosive medium and strong electromagnetic field interference around the machine). In addition, some instruments have special requirements for the environment and shall be maintained in strict accordance with the operating instructions;
2. Keep the Melt Flow Index Tester clean and avoid collision before and after use;
3. When the Melt Flow Index Tester is not used for a long time, it should be plugged in and started regularly;
4. The Melt Flow Index Tester shall be in the charge of a specially assigned person. The test shall be carried out in strict accordance with the operating procedures. It is strictly prohibited to carry out tests beyond the test range. After the test, the instrument shall be restored to its original position to ensure the normal operation of the next test;
5. The Melt Flow Index Tester shall be cleaned and inspected regularly, and the instrument to be calibrated shall be calibrated to ensure the accuracy of the instrument;
6. When the Melt Flow Index Tester is not used, appropriate protective measures shall be taken. If it is not used for a long time, it can be used only after re inspection;
7. Regular calibration, etc.
