三、工作原理:

熔体流动速率仪是在规定温度条件下,用高温加热炉使被测物达到熔融状态,这种熔融状态的被测物,在规定的砝码负荷重力下通过一定直径的小孔进行挤出试验,挤出物的质量折算为10分钟的挤出量。在工业企业的塑料生产及科研单位的研究中,经常用“熔体(质量流动速率)”来表示高分子材料在熔融状态下流动性能。

3. Working principle:

The melt flow rate instrument is to use a high temperature heating furnace to make the test object melt under a specified temperature condition. This molten state test object is extruded through a small hole of a certain diameter under a specified weight load gravity In the test, the mass of the extrudate was converted into the extrusion volume of 10 minutes. In the research of plastic production and scientific research units of industrial enterprises, "melt (mass flow rate)" is often used to express the flow properties of polymer materials in the molten state.

★异常现象发生,如不能控温,不能显示等,应关机,进行检修

★清洗活塞杆时,不能用硬物刮削。

Five, matters needing attention:

★ Single-phase power sockets must have grounding wire holes and be reliably grounded.

★ If an abnormal display appears on the LCD, press the "Reset" button.

★ In normal operation, if the furnace temperature is higher than 450 ℃, the software is protected and the heating is interrupted.

★ Abnormal phenomena, such as temperature control and display failure, should be shut down for maintenance

★ When cleaning the piston rod, do not scrape with hard objects.
