Failure analysis of plastic Melt Flow Index Tester

Plastic Plastic Melt flow index tester is used to measure the melt flow rate of various polymers in viscous flow state. It is suitable for polycarbonate, polysulfone, fluoroplastics, etc. with high melting temperature. It is also suitable for testing plastics with low melting temperature such as polyethylene, polystyrene and resin. The instrument meets the provisions of GB and ISO standards and is widely used in plastic manufacturers, colleges and universities, scientific research institutions and commodity inspection departments.
Melt flow rate refers to the mass or volume of thermoplastic melt passing through the standard die every 10 minutes at a certain temperature and load. The instrument is only applicable to the measurement of melt flow rate (MFR) by mass method, and its value can characterize the viscous flow characteristics of thermoplastic in molten state.

When testing the plastic melt index instrument, the sample shall be carefully placed to avoid the powder and particles from entering the internal electronic board of the melt index instrument, resulting in poor heat dissipation performance of the integrated circuit and easy failure.
The piston rod of the Melt Flow Index Tester can maintain vertical movement in the inner hole of the barrel, which depends on the two-point positioning of the axis. First, the tolerance fit between the measuring head of the rod and the inner hole of the barrel is about 0.075mm, and second, the tolerance fit between the middle part of the rod and the guide sleeve, so that the rod can move up and down freely in the barrel without skewing and remain vertical. And theoretically, the longer the service life, the smaller the friction coefficient and the more flexible. During operation, the guide sleeve is well fixed, which can effectively prevent the bending deformation of the material rod, which is often neglected by the tester. Moreover, the tester seldom noticed the flexible movement of the material bar. After use for a period of time, there is an obvious thin layer of coking material on the piston rod of the melt index instrument. Even if the piston rod is carefully cleaned every time, this layer of sediment will slowly form, and the inner wall of the guide sleeve will be neglected to be cleaned. After use for a period of time, the coordination between the piston rod and the guide sleeve becomes worse and more viscous.

The guide sleeve of the melt index meter is not properly placed so that it does not play a guiding role, resulting in the deflection of the piston rod. If these problems occur, the result will directly affect the small value of the measurement result of the melt index meter.
In addition, some users have a large workload, long working hours and often work continuously for 24 hours, resulting in rapid depreciation of the melt index instrument and high probability of failure.
The laboratory working environment also has a great impact on the normal operation of the instrument.
