Testing procedure

(1) Turn on the power of the HT-3682VM meltblown melt index tester, adjust the level, set the temperature to 230 C, close the die plate, then put the die into the charging cylinder, click the temperature control button to let the instrument start heating at 230

(2) After constant temperature to 230 , prepare 13 15ml polypropylene PP raw material, pour the raw material into the charging cylinder and compact it with the rod, then insert the 325g load piston rod into the charging cylinder, at this time the displacement rod is placed under the weight tray, but can not touch the piston disc, then press the 1835g load sleeve on the piston rod, click the timer, the instrument starts to count down 300 seconds.

(3) When the countdown of the instrument is over 300 seconds, there will be an alarm sound, and then click Run, and then push the die baffle away, the raw material will be extruded under the load pressure of 2160g, when the piston rod touches the encoder, the instrument will start the timing. When all the raw materials are extruded, the timing will automatically end. The MFR value of the

melt-blown polypropylene PP raw material will be displayed on the screen.unit is g / 10min.

(5) Select the print result on the screen and automatically print out the test result. A

Note: According to the GB / T3682-2018 standard specification, the MFR value in the above test is the MVR value and the density obtained through the temperature of 230 .

FAQ's of High Melt Index PP Meltblown Melt Flow Rate Tester HT-3682VM Series:

Q: How does the HT-3682VM Series Melt Flow Rate Tester operate?

A: The HT-3682VM uses PID digital temperature control to precisely heat samples, and supports both automatic and manual cut-off modes. It measures the melt flow rate by extruding the polymer through a carburized steel die, with results displayed on the touch screen and stored or printed via the integrated micro-printer.

Q: What materials can be tested with this melt flow rate tester?

A: This instrument is designed for measuring the melt flow rate of a wide variety of thermoplastics, including polypropylene (PP), polyethylene (PE), and is especially effective for meltblown PP used in filtration and medical applications.

Q: When should I use the automatic versus manual cut-off feature?

A: Automatic cut-off is ideal for standard measurements, ensuring consistent timing and reduced operator error. Manual cut-off can be selected for special materials or research scenarios requiring more flexible test control.

Q: Where is this melt flow rate tester best utilized?

A: It is well-suited for quality control labs, research facilities, academic institutions, and manufacturing environments where reliable, repeatable melt flow rate results for thermoplastics are critical.

Q: What is the step-by-step process for running a test on the HT-3682VM?

A: Load the sample using a standard weight, set the desired test parameters on the LCD touch screen, allow the device to reach the setpoint temperature (about 8 minutes), and start the test. The machine will measure the melt flow rate, display results instantly, and output data to the micro-printer or via USB/RS232.

Q: How does the built-in alarm system benefit the user?

A: The over-temperature alarm and fault alert system help prevent damage to the instrument or test samples, improving lab safety and ensuring accurate, uninterrupted operation during testing.
