Melt Flow Indexer

use

The melt flow rate meter is an instrument for measuring the flow properties of plastic polymers at high temperatures according to the test method of GB3682-2000. It is used for high polymers such as polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, and nylon fluoroplastics. Determination of the melt flow rate of a substance at high temperature. It is suitable for the production and research of factories, enterprises and scientific research units.

Principle

The melt flow rate meter is an extrusion plastic meter. It uses a high-temperature heating furnace to make the measured object reach a molten state under specified temperature conditions. The test object in this molten state is extruded through a small hole of a certain diameter under the load gravity of the specified weight. In the plastic production of industrial enterprises and the research of scientific research units, "melt (mass) flow rate" is often used to express the physical properties of polymer materials such as fluidity and viscosity in the molten state. The so-called melt index refers to the average weight of each section of the extruded sample converted into the extruded amount in 10 minutes.

Precautions

1. The single power socket needs to have a ground wire hole and be reliably grounded.

2. If there is an abnormal display on the liquid crystal display, it should be turned off first, and then restarted to reset the test temperature and start working.

3. During normal operation, if the furnace temperature is higher than 450°C, the software will protect, interrupt heating, and send out an alarm.

4. If any abnormal phenomenon occurs, such as unable to control the temperature, unable to display, etc., it should be shut down and repaired.

5. When cleaning the piston rod, do not scrape it with hard objects.

Standard test force (eight grades)

Level 1: 0.325 kg= (piston rod + weight tray + heat insulation sleeve + No. 1 weight body) =3.187N

Level 2: 1.200 kg=(0.325+No. 2 0.875 weight)=11.77 N

Level 3: 2.160 kg=(0.325+No. 3 1.835 weight)=21.18 N

Level 4: 3.800 kg=(0.325+No. 4 3.475 weight)=37.26 N

Level 5: 5.000 kg=(0.325+No. 5 4.675 weight)=49.03 N

Level 6: 10.000kg=(0.325+No. 5 4.675 weight+No. 6 5.000 weight)=98.07 N

Level 7: 12.000 kg=(0.325+No. 5 4.675 weight+No. 6 5.000+No. 7 2.500 weight)=122.58 N

Level 8: 21.600 kg=(0.325+No. 2 0.875 weight+No. 3 1.835+No. 4

3.475+No. 5 4.675+No. 6 5.000+No. 7 2.500+No. 8 2.915 weight)=211.82 N
