Crosslink density rapid test_NMR The NMR polymer material detection system provides a comprehensive range of scientific solutions for a wide range of materials, from elastomeric materials such as rubber to membrane materials and nanomaterials in the biological field. New height of material research Simple and fast Easy to set parameters for a few minutes to complete sample testing Lossless green There is no special requirement for sample morphology without chemical treatment, and both solid and liquid samples can be repeatedly tested. Precise temperature control Wide temperature range from room temperature to 150 °C, precise temperature control system combined with excellent hardware to provide stable and accurate experimental conditions for scientific research Powerful application support Online research Q&A, your research, I am involved in failure problems, and respond quickly to on-site service Covering a wider range of applications Rubber elastomers, polymeric materials, aerospace materials, functional film materials, nanocomposites, gels and porous materials rubber: Rapid assessment of crosslink density Compared with the swelling method, the nuclear magnetic method has obvious advantages. The nuclear magnetic method obtains the chemical and physical crosslink density of rubber by detecting the motion characteristics of the rubber polymer chain, and the chemical method can only detect the chemical crosslink density; Quickly predict the mechanical properties of rubber Alcohol Spray,Spray Hand Sanitizer,Hand Sanitizer Alcohol,Hand Sanitizer Liquid Wuxi Keni Daily Cosmetics Co.,Ltd , https://www.kenidailycosmetics.com
NMR technology not only provides a single detection value, but also provides a full-time, long-term online monitoring for process improvement, process research, etc. without loss, rapid and convenient analysis.
Sample testing can be completed in a few minutes; no chemical treatment is required, green and environmentally friendly; easy to operate, high precision; the same sample can be repeated multiple times and other longitudinal experiments;
Suitable for natural rubber, composite rubber, reclaimed rubber powder and polyolefin materials such as plastics The nuclear magnetic T2 relaxation reflects the motion characteristics of the cross-linked network segment according to the dipole action of the intermolecular hydrogen proton. When the crosslink density changes (especially physical cross-linking), the molecular chain's motion pattern changes, and the macroscopic representation is the deformation force. Physical properties such as stress-strain change. The combination of nuclear magnetic resonance technology and chemometrics quickly predicts multiple mechanical properties of rubber, providing an effective and rapid detection method for actual production and quality control.
