1、 Overview of this device:
Our melt flow rate meter adopts the latest technology from the United States and is an instrument for measuring the flow performance of thermoplastic polymers at high temperatures. It is used for polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, etc... Determination of melt flow rate of polymers at high temperatures. Applicable to the production and research of factories, enterprises, and research institutions.
This instrument complies with the requirements of JB/T5456 standard and is applicable to GB/T3682 and ISO1133.. This standard is widely used for the determination of the melt index value of thermoplastic materials.
2、 Working principle:
The melt flow rate meter is a type of extrusion plastic meter. It is to use a high-temperature heating furnace to bring the measured object to a molten state under specified temperature conditions. The tested object in this molten state is subjected to extrusion testing through a small hole of a certain diameter under the specified weight load gravity. In plastic production in industrial enterprises and research in scientific research institutions, the "melt (mass) flow rate" is often used to represent the physical properties of polymer materials such as fluidity and viscosity in the molten state.
