Fine grained soil three-axis nuclear magnetic microstructure analyzer

Fine grained soil triaxial nuclear magnetic microstructure analyzer (such as MacroMR12-150V-I) is a high-end equipment designed specifically for complex geotechnical engineering research. This device innovatively combines a vertical permanent magnet with a soil triaxial compression system, suitable for rock and soil samples with diameters ranging from 25 to 100mm; #160;. Not only does it have basic T1/T2 relaxation spectrum measurement and proton density weighted imaging functions, but the core breakthrough lies in the realization of in-situ joint measurement under multi field coupling conditions. While achieving multi field coupling such as temperature field, pressure field, chemical field, and seepage field, it is organically combined with traditional mechanical measurement methods such as soil triaxial.

In the fields of soil science, agricultural engineering, and geotechnical disaster prevention and control,Fine grained soil three-axis nuclear magnetic microstructure analyzerIt is becoming an indispensable frontier tool for studying the microscopic characteristics of soil. Its core technology, low field nuclear magnetic resonance technology, with its unique advantages of non-destructive, accurate, and dynamic, is profoundly changing the research paradigm of traditional soil physical properties.

1、 Application background of low field nuclear magnetic resonance technology in soil research

Traditional soil testing methods, such as dry drying, tensiometer, or centrifugation, can provide basic moisture data, but they generally have limitations such as time-consuming processes, damage to the original structure of the sample, and difficulty in distinguishing different forms of moisture (such as bound water, capillary water, free water). With the deepening of research on soil hydrological processes and engineering performance, researchers urgently need a technology that can detect soil moisture and pore structure in situ, continuously, and finely. The introduction of low field nuclear magnetic resonance technology has precisely filled this gap, achieving a leap from macroscopic measurement to microscopic insight, and providing new theoretical and technical support for soil degradation mechanisms, precision agricultural irrigation, and geological hazard prediction.

2、 Principles and core advantages of low field nuclear magnetic resonance technology

The physical basis of low field nuclear magnetic resonance technology originates from the relaxation characteristics of atomic nuclei in a magnetic field. Hydrogen protons in soil (mainly present in water) are magnetized in a low-intensity permanent magnetic field. When a specific frequency of radio frequency pulse is applied, hydrogen protons resonate and absorb energy; After the pulse stops, hydrogen protons release energy and return to equilibrium, a process called "relaxation". The relaxation time (T2) detected by the instrument contains rich information: the length of the relaxation time directly reflects the degree of binding of water. The more tightly water molecules are bound by soil particles (such as strongly bound water on the surface of clay particles), the shorter the relaxation time; And free water with high degrees of freedom stored in large pores has a longer relaxation time.

Compared with traditional methods, this technology has significant advantages:

Non destructive and fast: No need to damage the sample, continuous dynamic measurement of the same sample can be carried out, greatly improving experimental efficiency and data coherence.

Accurately distinguish water states: It can quantitatively distinguish bound water, capillary water, and free water, which is incomparable to traditional methods that can only determine total water content.

Multidimensional information acquisition: Relaxation spectra can not only reflect water distribution, but also invert information such as soil pore size distribution and specific surface area, and simultaneously obtain multiple physical indicators in one measurement.
