Fiber oil content analyzerIt is a fiber enterprise small nuclear magnetic resonance, which has been maturely applied to the analysis and testing of fiber oil content. It is equipped with fiber oil content testing software, which is convenient and fast for testing, user-friendly for software operation, and very easy to use. The instrument integrates good technology in appearance design, hardware configuration, and software operation, and is constantly upgraded to ensure a good combination of product performance and friendly customer experience. The use of this instrument to measure the oil content on fibers can significantly improve the labor production efficiency of enterprises, monitor the product quality of fibers in real time, reduce the risk of employees being harmed by chemical reagents, reduce the cost of treating chemical reagent waste liquid, and save labor costs and fiber oil dosage.
Fiber oil content analyzerThe principle of measurement technology:
Both chemical fibers and fiber oils are rich in hydrogen atoms, and nuclear magnetic resonance technology can detect the signal of hydrogen atoms and quantitatively calculate the corresponding content based on the strength of the signal. Due to the solid nature of fibers, the signal of hydrogen atoms decays rapidly; The hydrogen atom signal in the fiber oil agent decays slowly, so when selecting appropriate measurement parameters, the fiber signal can be filtered out and only the signal of the fiber oil agent can be retained and measured.
For special fibers such as carbon fiber or glass fiber, the fiber itself does not contain hydrogen atoms, so all signals detected by nuclear magnetic resonance technology come from the fiber oil agent.
