Introduction
The melt flow rate instrument testing machine (also called melt index) is the determination of thermoplastics under certain conditions the melt flow rate of special equipment.Thermoplastics melt flow rate (melt index) refers to the plastic under a certain temperature and load, the melt every 10 minutes by the quality of the standard mouth die capillary or molten volume, with the MFR (MI) or MVR value, it can be the difference between viscous flow characteristics of thermoplastics under the molten state.Of thermoplastic plastics and chemical fiber raw materials, products, and other products quality guarantee has important significance.
Features
1. The latest research and development of WS control system, the test process temperature, time, and the displacement value can real-time display;
2. Smooth automatic loading device, can according to need to load the test load, reducing the manual loading of trouble;
3. Choose a 8.4 -inch LCD, touch screen, make the operation more human, click on the touch screen can modify parameters, send commands, etc;
Choose high precision rotary encoder, 4. Displacement measurement, high accuracy, measurement is accurate.The rotatable structure design, make the operation more convenient;
5. Furnace heat preservation effect is good.
6. Choose the micro printer, can print test results of real-time, convenient and practical.
