Reasonable maintenance method for melt flow index instrument

1. Firstly, check whether the working environment of the melt flow index instrument meets the working environment of the melt index instrument. According to the requirements of the manual, check whether the ambient temperature, humidity and dust conditions will affect the normal operation of the melt index instrument.
2. Check whether the power supply voltage of the melt index meter meets the requirements, whether the current is sufficient, whether there is a reliable grounding wire, whether the power supply has strong fluctuations, and whether there is strong electromagnetic interference nearby.
3. The meltflowindex instrument should be operated by specialized personnel, carefully read the instruction manual, and be proficient in the operation steps and procedures, so as to achieve the accuracy of the test, extend the service life of the instrument, and ensure the safety of the test.
4. After one test of the melt flow index tester, it is necessary to thoroughly clean the piston rod, barrel, die and other parts contaminated with raw materials with pure cotton cloth while it is hot, so as to ensure the flexible operation of the various parts of the instrument. When cleaning, pay attention to avoid hard objects scratching the precision parts such as the barrel and die.
5. When the instrument is stored for a long time, it should be turned on and baked regularly, and the metal parts should be coated with a proper amount of anti-rust oil before sealing.
6. The temperature of the melt flow index testershould be calibrated regularly.
