Introduction: The WKT-450E melt flow rate meter is a high-precision automatic melt flow rate meter tester. It is used to determine when various plastics and resins pass a certain temperature and load in a viscous flow state, and pass through a standard die every 10 minutes. Its characteristic is that it does not need to manually load the weights, the instrument automatically selects the weights corresponding to the material, automatically loads, automatically takes out, and the instrument can be interconnected with a computer, operate and save data on the computer, and issue reports. This melt flow rate meter is suitable for the determination of the specified thermoplastic melt mass flow rate in the national standard "GB/T3682-2000 Thermoplastic Melt Mass Flow Rate and Melt Volume Flow Rate Determination". This standard is equivalently adopted It complies with the requirements of ISO1133:1997 and can meet the ASTM D1238 test standard at the same time The instrument has simple structure, convenient use, accurate measurement, stable and reliable performance. This instrument is not only suitable for testing plastics with low melting temperature such as polyethylene, polypropylene, polystyrene, ABS resin, but also for testing engineering plastics such as polycarbonate, fluoroplastics, nylon, etc., with high melting temperature. It is widely used in plastic production, plastic products, petrochemical industries and related universities, research institutes, and commodity inspection departments. Features: 1. Multi-section (5 sections) temperature control mode, 5 groups of platinum resistance sensors, 5 heating jackets for individual temperature control, high-precision intelligent PID control, and the heating slope, that is, the heating speed can be adjusted; 2. The temperature resolution is 0.1℃, the temperature uniformity is 0.2℃, the temperature fluctuation within 24 hours does not exceed 0.5℃, and the displacement sensor resolution is 0.001mm; 3. Temperature over-temperature protection device; 4. Manual automatic cutting is integrated, and the cutting time (0~999) and the number of cutting times (0~999) can be set arbitrarily; 5. The mass method, or volume method, or both test methods can be selected when testing, and the flow rate ratio can be calculated. In both methods, the test starts when the piston rod moves to a certain position; 6. Built-in temperature stability warning alarm, and add 240 seconds (GB3682 regulations) material warm-up seconds countdown, after the countdown, a beep will sound, and the American standard (ASTM) warm-up time can also be set; 7. Built-in a variety of plastic material melt index test conditions, convenient for customers to call and use at any time, reduce tedious workload, and store the last test conditions and results; 8. The machine has beautiful appearance, reasonable design, stable performance and convenient operation; 9. Built-in micro printer to facilitate printing test data; 10. High-precision touch screen controller, 4.3-inch touch screen, can store and print the latest test conditions and data, the test print menu settings include test time (system default), operator, material name, test method, test conditions (temperature, Weight of weight, cutting time interval), test result data, test result artificial judgment OK or NG, etc.; 11. The RS232 interface or USB interface is reserved to connect to the computer, and the operation of the instrument can be controlled through the computer and the test data can be transferred and saved to the computer; 12. The weight can be loaded manually or the ball screw can be driven to rotate by a stepper motor to achieve the purpose of automatically controlling the rising or falling of the top loading weight.
