ZY-3004 Melt Flow Rate Meter

1、 Overview

This melt flow rate meter is used to measure the melt flow rate of various polymers in a viscous flow state. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, and fluoroplastics with high melting temperatures, as well as for testing materials such as polyethylene, polystyrene, polypropylene, ABS resin, and polyoxymethylene resin with low melting temperatures. It is widely used in plastic production, plastic products, petrochemical industries, as well as relevant universities, research institutions, and inspection departments.

This melt flow rate meter meets the testing methods for the mass flow rate and volume flow rate of thermoplastic melts specified in GB/T 3682-2000 "Determination of mass flow rate and volume flow rate of thermoplastic melts", ISO 1133:2011, and ASTM D 1238-2010 standards. Before use, please read this user manual carefully.

The main body is a desktop structure with reasonable design, stable and reliable performance, beautiful appearance, and easy operation. It adopts high-performance and high-precision control instruments with high sampling accuracy and fast control rate. Fuzzy PID algorithm is used for constant temperature control.

2、 Working principle

The melt flow rate refers to the mass of thermoplastic material passing through a standard die every 10 minutes at a certain temperature and load, expressed as MFR, and the volume passing through the standard die every 10 minutes, expressed as MVR. These values can characterize the viscous flow characteristics of thermoplastic material in the molten state, as described in parts 6 and 7 of GB/T 3682-2000 "Determination of Melt Mass Flow Rate and Melt Volume Flow Rate of Thermoplastic Materials".

Formula expression: MFR (θ, mnom)=ref × m/t=600 × m/t (g/10min)

In the formula: θ - test temperature
