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;
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

Quickly predict the mechanical properties of rubber

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.
