2results about How to "Self-supporting" patented technology

This utility model relates to an anti-collapse corrugated tube-type cleanroom cable chain, belonging to the field of cable chain technology. It includes a cleanroom cable chain body and an anti-collapse structure. The cleanroom cable chain body is a tubular structure with multiple annular protrusions along its circumference. The anti-collapse structure is fixed to the annular protrusions and protrudes from the surface of the annular protrusions. This structure, by providing multiple annular protrusions along the circumference of the cleanroom cable chain body and designing the anti-collapse structure as a cuboid, prevents downward deformation of the cleanroom cable chain body surface when it bears the weight of the pipeline. This gives the cleanroom cable chain self-support, eliminating the need for external support, simplifying equipment layout, and reducing equipment costs.

The application discloses a kind of PdO-SnO2-SiO2 / SiO2 Self-supporting flexible gas-permeable nanofiber membrane gas sensor and preparation method thereof.Si electrospinning fiber is prepared by single needle head electrospinning method first, then Si electrospinning fiber and Pd-Sn electrospinning fiber interwoven fiber membrane is prepared on it by double needle head electrospinning method, then PdO-SnO2-SiO2 / SiO2 Flexible gas-permeable nanofiber membrane is obtained by heat treatment, finally electrode is prepared on its surface to obtain gas sensor.SiO2 Nanofiber in the sensor of the application has good flexibility, as a framework material to ensure the flexibility of the fiber membrane;Interwoven fiber membrane can effectively prevent SiO2 Nanofiber and PdO-SnO2 Nanofiber from separating, and has good gas permeability;At the same time, the fiber membrane is all inorganic material, which can maintain the original shape at high temperature, has good high temperature resistance and gas sensitivity.The sensor of the application has simple preparation process, stable performance, wide range of use, low cost, and has broad application prospect.
