三、熔體流動(dòng)速率儀工作原理：
熔體流動(dòng)速率儀是在規(guī)定溫度條件下，用高溫加熱爐使被測(cè)物達(dá)到熔融狀態(tài)，這種熔融狀態(tài)的被測(cè)物，在規(guī)定的砝碼負(fù)荷重力下通過一定直徑的小孔進(jìn)行擠出試驗(yàn)，擠出物的質(zhì)量折算為10分鐘的擠出量。在工業(yè)企業(yè)的塑料生產(chǎn)及科研單位的研究中，經(jīng)常用“熔體（質(zhì)量流動(dòng)速率）"來表示高分子材料在熔融狀態(tài)下流動(dòng)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.
