Important: Melt flow indexer user guide

Melt flow indexer is an instrument for measuring the fluidity of plastic melts, usually used for quality control in plastic processing. The following is how to use the Melt flow indexer.

1. Preparations

Before using the Melt flow indexer, some preparatory work is required. First of all, check whether the instrument is intact and whether the parts of the instrument are complete. Second, prepare the samples and standard weights to be tested.

2. Install the sample

Cut the sample to be tested to a certain length and insert it into the sample slot of the Melt flow indexer. Note that the sample tank should be kept dry and clean so as not to affect the test results.

3. Set test parameters

Set the test parameters of the Melt flow indexer according to the sample type and test standard to be tested. These parameters include test temperature, load, test time, etc. Usually, different sample types and standards require different test parameters, so it needs to be set according to the actual situation.

4. Run the test

After setting the test parameters, you can start the test. Turn on the power switch of the Melt flow indexer, wait for a while until the instrument is stable, press the test button to start the test. During the test, the instrument will automatically record the test data and stop automatically after the test is over.

5. Record test results

After the test, the test results can be read from the Melt flow indexer. Test results usually include data such as melt flow index, melt density, etc. Record the test results and compare with the standard value to determine whether the quality of the sample meets the requirements.

6. Clean the instrument

After the test, the Melt flow indexer needs to be cleaned. Take the sample holder and other parts out, wash them with detergent, and dry them with a clean cloth. Note that the Melt flow indexer should be cleaned and maintained frequently to ensure the accuracy of the test results and the long-term stability of the instrument.

The above is the usage method of Melt flow indexer summarized by QINSUN instrument engineers for you, I hope it will be helpful to you.
