Full automatic melt flow rate meter

Model: JZY-4000A

1、 Product introduction:

This is a high-precision full-automatic melt flow rate meter, which is used to measure various plastics and resins passing through a certain temperature and load in the viscous flow state, and passing through the standard die every 10min; The MFR/MVR value of melt flow rate is applicable to engineering plastics such as polycarbonate, polysulfone, fluoroplastic and nylon with high melting temperature, as well as testing plastics with low melting temperature such as polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM) and polycarbonate (PC) resin. It is widely used in plastic production, plastic products, petrochemical and other industries, as well as relevant universities Scientific research institutions and commodity inspection departments< br />
2、 Executive standard:
GB/T3682-2000
Thermoplastics Determination of melt flow rate and melt volume flow rate
ISO 1133：1997
Thermoplastics Determination of melt mass flow rate MFR and melt volume flow rate MVR
ASTM D1238
Standard Test Method for Melt Flow Rate of Thermoplastics by Extrusion Plastometer
3： Product advantages:
Multi segment (3-segment) temperature control mode, 3 sets of platinum resistance sensors, 3 heating jackets for independent temperature control, high-precision intelligent PID control, and adjustable temperature rise slope, i.e. temperature rise speed
The temperature resolution is 0.1 ℃, the temperature uniformity is 0.2 ℃, and the temperature fluctuation within 24 hours does not exceed 0.5 ℃,
The resolution of displacement sensor is 0.001 mm.
Temperature over temperature protection device
Manual and automatic cutting is integrated, and the cutting time (0~999) and cutting times (0~999) can be set at will
The mass method, volume method or both methods can be selected for the test, and the flow rate ratio can be calculated. Both methods start the test when the piston rod moves to a certain position.
Built in temperature stability prompt alarm, and add 240 seconds (GB3682) material preheating second countdown. After the countdown, a prompt tone will be given, and American Standard (ASTM) and other preheating time can also be set.
Built in a variety of plastic material melt index test conditions, convenient for customers to use at any time, reduce the tedious workload, and store the last test conditions and results
Built in micro printer for easy printing of test data
High precision touch screen controller, 7-inch touch screen, can store and print the latest test conditions and data. The setting of the test and print menu includes the test time (default of the system), operator, material name, test method, test conditions (temperature, weight, cutting time interval), test result data, test result, artificial judgment of OK or NG, etc,
RS232 interface or USB interface is reserved to connect with computer, which can control instrument operation and transmit and save test data to computer,
The weight can be loaded manually or the ball screw can be driven to rotate by a stepping motor to automatically control the rise or fall of the top loading weight
