How Does the Melt Flow Index Tester Work?
The Melt Flow Index Tester Price is a precision instrument designed to measure the flow properties of thermoplastic polymers under controlled conditions. The testing process involves heating the polymer sample to a specific temperature and applying a defined load or force to push the material through a small orifice, known as a die. The amount of material that flows through the die in a given time period (usually 10 minutes) is measured and reported as the Melt Flow Index (MFI), typically in grams per 10 minutes (g/10 min).
Key Components of the Melt Flow Index Tester:
1. Heating Chamber: The polymer sample is placed inside the heating chamber, where it is heated to the appropriate testing temperature. The chamber’s temperature is precisely controlled to ensure consistent testing conditions.
2. Piston and Load: A piston applies a predetermined load to the polymer sample, forcing it through the die. The weight of the load is selected based on the specific material being tested, as defined by relevant testing standards.
3. Capillary Die: The die is a small, cylindrical orifice through which the molten polymer flows. The dimensions of the die are standardized, ensuring uniformity in testing results across different laboratories.
4. Cutting Mechanism: Some advanced MFI testers are equipped with automatic cutting mechanisms that periodically cut the extruded polymer to facilitate more accurate measurements.
