Overview
YOUKE YK3650A volume method 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 measurement of melt flow rate of polymers such as polyethylene (PE), polypropylene (PP), polyformaldehyde, ABS Resin, polycarbonic acid ester, nylon fluoroplastics, etc. The instrument is suitable for the production and research of factories and R & D institutions.
Features
1. Adopt MCU Power Temperature control mode, strong anti-interference ability, high temperature control accuracy and 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 force, weight mass relative error ≤ 0.5%.
4. Equipped with software overheating protection function, when the furnace temperature exceeds 450 ° C, the heating is interrupted and the alarm is raised.
Principle
The melt flow rate meter is an extrusion plastic meter. It uses a high-temperature heating furnace to achieve 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 specified weight load gravity. By measuring the mass or volume of the extrudate, the melt (mass) flow rate (MFR, unit: grams/10 minutes) or the melt (volume) flow rate (MVR, unit: cubic centimeters/10 minutes) are calculated to indicate the flowability, viscosity and other physical properties of the polymer material in the molten state.
Applications
Factory enterprises, R & D institutions
Steps
The information does not provide specific operation steps.
Notice
• A single power socket needs to have a grounding hole and be reliably grounded.
• If there is an abnormal display on the LCD display, it should be turned off first, and then the test temperature should be reset after turning it on, and the work should be started.
• During normal operation, if the furnace temperature is greater than 450 ° C, the software will protect, interrupt the heating, and issue an alarm.
• If any abnormal phenomenon occurs, such as temperature control, display, etc., it should be shut down for maintenance.
• When cleaning the piston rod, do not scrape it with hard objects.
