This invention relates to the field of cable manufacturing materials technology, specifically disclosing a semi-conductive power cable wrapping tape and its preparation method. The wrapping tape includes a reinforcing substrate layer and a semi-conductive functional layer coated on one side thereon. The semi-conductive functional coating liquid is composed of oxime-containing polysiloxane, aminated conductive filler, polyisocyanate crosslinking agent, catalyst, and reaction inhibitor. This invention constructs a stable conductive network through the chemical anchoring structure formed by the aminated conductive filler and the oxime-containing polysiloxane, significantly improving interfacial bonding and effectively inhibiting the migration and detachment of the filler under mechanical deformation. Simultaneously, utilizing the topological rearrangement characteristics of dynamic bonds, it endows the material with excellent crack propagation resistance and a certain structural reorganization potential, helping to delay material aging and damage accumulation. Combined with the step-by-step dripping process and the synergistic effect of the reaction inhibitor, latent curing is achieved, avoiding bubble and gelation problems during construction.

This invention discloses a centrifugal microfluidic chip and a nucleic acid extraction method, specifically relating to the field of nucleic acid extraction technology. The method includes a pretreatment filtration module and a nucleic acid extraction and purification module. The sample solution undergoes primary and secondary filtration in the pretreatment filtration module to remove particulate impurities and protein precipitates, obtaining a clear sample supernatant. Nucleic acids in the supernatant are captured by a silica membrane in the nucleic acid extraction and purification module. Subsequently, a first washing solution and a second washing solution flow sequentially through the silica membrane to wash the adsorbed nucleic acids, removing residual impurities and reaction inhibitors. Finally, the eluent flows through the silica membrane, carrying the nucleic acids into the nucleic acid collection chamber, thereby obtaining the purified nucleic acid sample. This invention features a simple structure and reliable control, enabling sequential control of liquids in multiple chambers, effectively removing impurities and inhibitors from the sample, improving nucleic acid extraction efficiency and purity, and achieving a high degree of integration and automation in the nucleic acid extraction process for soil samples.
