四、工作原理

       WJ400D熔体流动速率仪是塑料挤出仪器。它是在规定温度条件下,用高温加热炉使被测物达熔融状态。这种熔融状态的被测物,在规定的负荷下通过一定直径的小孔进行挤出试验。在塑料生产中,常用熔融指数来表示高分子材料在熔融状态下的流动性、粘度等物理性能。所谓熔体质量流动速率就是指挤出的各段试样的平均重量折算为10分钟的挤出量。

WJ-400D Melt Flow Rate Measuring Instrument

Purpose:

WJ-400D Melt Flow Rate Meter conforms to GB/T 3682 Standard for Measuring Melt Mass Flow Rate and Melt Volume Flow Rate of Thermoplastic Polymers. It is used to determine the flow MI of thermoplastic polymers at high temperature, such as polyethylene PE, polypropylene PP, resin ABS, polycarbonate PC, nylon PA6 and other plastic raw materials. This product is widely used in plastic raw material factories, plastic products factories, petrochemical companies and other industries, as well as related colleges and universities, scientific research institutes and quality inspection units.

2. Compliance with standards:

The instrument implements the requirements of JB/T5456 standard and is applicable to GB/T3682, ASTM D1238, ISO1133 and other standards.

3. Characteristics:

The instrument is controlled by touch screen and Chinese characters are displayed. Automatic temperature control, automatic cutting, real-time display of each section of the test curve, with the function of micro-print data, can display and print up to eight sections of experimental data and the average value of the results of each section can also achieve "time-controlled cutting, displacement cutting".

Among them, WJ-400D melt flow rate meter has two measuring methods of mass (MFR) and MVR, and has the function of automatic measurement of melt density.

4. Working Principle

WJ-400D melt flow rate meter is a plastic extrusion instrument. It uses a high-temperature heating furnace to melt the measured material at a specified temperature. The extrusion test of the molten material is carried out through a small hole of a certain diameter under a specified load. In the production of plastics, melting index is often used to express the physical properties of polymer materials such as fluidity and viscosity in the melting state. The so-called melt mass flow rate refers to the average weight of each section of the extruded sample converted to 10 minutes of extrusion volume.
