英國海默生ViscoJet一體式在線粘度計
Hydramotion公司生產的在線粘度計可用于任何粘度量程及任何流體的粘度測量,相比使用傳統的離線粘度監測方法(取樣測試),在線粘度計監測下,可觀測到反應過程中粘度隨時間變化的曲線,粘度是分子量的標志,因此該方法的關鍵在于解決了聚合反應終點的準確確定。該設備對粘度微小變化有很高的敏感。即使是在某些很苛刻的條件下,也可得到所期盼的準確度,而且有母系的可安裝的或手提式設備可供固定或便攜安裝。動力及運動粘度可以在任何常規單元中顯示相關的參數(例如參考一個特殊溫度的粘度)也可以獲得。
使用在線粘度計后,它可以連續地監測粘度,從而提高產品質量的同時,縮短了生產周期,提高間歇式聚合的工藝水平,實際表明,采用在線粘度計后,生產周期提高10%-20%,次品減少10%-20%,可準確的控制很多個不同產品等級的反應終點。
