Overview
YOUKE YK3650 Melt index meter is an instrument for measuring the flow performance of plasticity polymers at high temperature. It is suitable 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. The instrument is widely used in the production and research of factories and R & D institutions.
Features
1. Conform to GB3682-2000 standard test method
2. Provide eight standard test forces, ranging from 0.325kg to 21.600kg
3. Temperature range 50~ 400 ℃, thermostatic accuracy +/- 0.5 ℃
4. Adopt LCD display for intuitive operation
5. With software protection function, automatically interrupt heating and alarm when the furnace temperature is greater than 450 ° C
Principle
The melt flow rate meter is an extrusion plastic meter. Under the specified temperature conditions, the test object is melted in a high temperature heating furnace. The test object in this molten state is extruded through a small hole of a certain diameter under the specified weight load gravity. By calculating the average weight of the sample in each section of the extrudate, it is converted into the extrusion amount of 10 minutes, that is, the melt index, which represents the flowability, viscosity and other physical properties of the polymer material in the molten state.
Applications
Determination of melt flow rate of polyethylene (PE), polypropylene (PP), polyformaldehyde, ABS Resin, polycarbonic acid ester, nylon fluoroplastics and other polymers, factory production, R & D institutions
Steps
1. Turn it on and set the test temperature
2. Start the work to melt the tested object at high temperature
3. Extrude specimens through small holes under weight loading
4. measurement of extrudate weight and calculation of melt index
Notice
• A single power socket needs to have a ground wire hole and be reliably grounded
• If there is an abnormal display on the LCD display, shut down first, then reset the test temperature after turning it on, and start the work
• In normal operation, if the furnace temperature is greater than 450 ° C, the software protection, 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
