常見問題解答


1.什麼是熔體流速測試儀?


熔體流動速率測試儀(也稱為熔融指數測試儀)是一種用於測定熱塑性材料在熔融狀態下的流動特性的專用儀器。它測量

 在規定的溫度和載荷條件下,在10分鐘內通過標準口模的熔體的質量(MFR)或體積(MVR)為材料流變學評估提供必要的數據。


2. MFR與MVR有何區別?


- MFR:透過測量規定時間內擠出的物料質量來確定,單位為g/10min。

- MVR:透過記錄活塞在固定時間內移動的位移,或活塞行進固定距離所需的時間來確定,單位為cm³/10min。

當材料在測試溫度下的熔體密度已知時,兩者可進行換算。


3. 測試依據哪些標準?


該儀器符合主要國際和國家標準,包括:

- GB/T 3682.1-2018(中國)

- ISO 1133:2011(國際)

- ASTM D1238-2013(美國)


4. 為何測試結果有時差異顯著(可達數倍)?


粉末材料的數據波動較大,通常源於測試過程中發生熱降解或交聯反應。添加適量的穩定劑(如抗氧化劑)可有效改善這一問題。


5. 測試值異常偏低的原因有哪些?


常見原因包括:

- 活塞或導向套上積碳導致摩擦增大,阻礙活塞平穩運動;

- 導向套未對中,使活塞桿傾斜;

- 料筒或口模清潔不徹底,有殘料留存。 排除以上因素對保證測量精度至關重要。


6. 日常保養有哪些建議?


- 料筒與口模:每次測試後趁熱清潔,防止殘留物固化後難以清除;

- 砝碼:定期檢查有無油污或銹蝕,保持表面潔淨;

- 加熱系統:定期清除加熱單元上的積塵,確保散熱良好;

- 長期存放:徹底清潔各部件,塗抹防銹油,置於乾燥環境;重新使用前,建議用標準參考物質校驗儀器精度。


7. 7吋觸摸屏的優勢是什麼?


7吋全彩觸摸屏提供直觀的人機交互界面,響應靈敏、操作便捷,支持中/英文雙語切換,特別適合初次接觸該類設備的用戶使用。


8. 溫控精度如何?


儀器溫度範圍為室溫~450℃,控溫精度達±0.2℃,可確保測試結果的高精度和良好重複性。


9. 可測試哪些材料?


本儀器適用於多種熱塑性塑膠,包括但不限於:

- 聚乙烯(PE)、聚丙烯(PP)

- ABS樹脂、聚碳酸酯(PC)

- 尼龍、氟塑料及其他工程塑料

- 橡膠及相關石化產品


10. 如何確保測試結果的準確性?


為保證數據的可靠性与重複性,建議:

- 定期校準溫度和位移感測器;

- 每次測試前徹底清潔料筒和口模;

- 使用認證標準物質進行日常驗證;

- 確保砝碼加載準確無誤;

- 嚴格遵照相關標準規定的測試條件進行操作。
