The fluorine-containing polymer is poly[4,5-difluoro-2,2bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene], with a refractive index of 1.31 and a density of 2.1-2.3 g/cm3. The particles have a particle diameter of 0.25-2.0 mm or a particle diameter 0.074 mm, and have irregular shapes. When particles of the fluorine-containing polymer are used as a transparent solid material for preparing a transparent frozen soil, the prepared transparent frozen soil has high transparency, low price, no toxicity and no harm, good similarity with the properties of a natural frozen soil body, can substitute natural frozen soil, is used for simulating complicated geological conditions, and is effectively used in model tests in geotechnical engineering."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Application of a fluorine-containing polymer in preparation of transparent frozen soil","description":"Particles of a fluorine-containing polymer used as a transparent solid material in an artificial transparent frozen soil is provided.
