Overview
SHUCHANG SC-MI-A Melt index meter is an instrument for measuring the flow performance of plasticity polymers at high temperature according to GB3682-2000 test method. It is used for the determination of melt flow rate of polyethylene (PE), polypropylene (PP), polyformaldehyde, ABS Resin, polycarbonic acid ester, nylon fluoroplastics and other polymers at high temperature. It is suitable for the production and research of factories and R & D institutions.
Features
1. Adopt single chip microcomputer to adjust power and temperature control mode, strong anti-interference ability, high temperature control accuracy, stable control
2. The heating wire is wound on the heating rod according to a certain rule to minimize the temperature layer and meet the standard requirements
3. Provide eight standard test forces, ranging from 0.325kg to 21.600kg
4. Temperature range 50~ 400 ℃, thermostatic accuracy +/- 0.5 ℃
5. weight mass relative error ≤ 0.5% to ensure measurement accuracy
Principle
The melt flow rate meter is an extrusion plastic meter that uses a high-temperature heating furnace to achieve a molten state under specified temperature conditions. The molten state of the test object is extruded through a small hole of a certain diameter under the specified weight load gravity. The average weight of the sample in each section of the extrusion is converted into the extrusion amount of 10 minutes to express the flowability, viscosity and other physical properties of the polymer material in the molten state.
Applications
Factory enterprises, R & D institutions
Steps
1. Set the specified temperature conditions to achieve a molten state
2. Select the appropriate weight load level
3. Extrude the test object in the molten state through the small hole under the weight load
4. Collect the extrudate sample and weigh it
5. Calculate the average weight of each section of the sample into 10 minutes of extrusion
Notice
• Power supply voltage must be kept within 220V +/- 10% 50Hz range
• environment temperature should be controlled between 10 ℃ -40 ℃
• environment relative humidity should be kept within the range of 30% -80%
• Confirm that the weight mass error does not exceed 0.5% before use
• When operating, ensure that the dimensions of each component meet the specifications and parameters
