4results about How to "Sufficient flexibility" patented technology

The utility model provides a superconducting cable skeleton and a superconducting cable, the superconducting cable skeleton comprises at least one layer of spiral skeleton, at least the outermost layer of spiral skeleton is formed by spirally twisting a strip-shaped metal plate, and at least one layer of spiral skeleton is provided with a cooling medium channel which spirally penetrates through the spiral skeleton along the spiral direction. The spiral framework can guarantee certain supporting performance, has sufficient flexibility and elasticity, and can be repeatedly bent. When the superconducting cable framework needs to be bent, the gaps on the spiral framework can provide enough bending space, and then the requirement for high flexibility is met. Meanwhile, at least one layer of spiral framework is provided with a cooling medium channel which spirally penetrates through the spiral framework in the spiral direction, and a cooling medium is introduced to provide stable cold conduction for the superconducting tape. After the superconducting tape is wound outside the superconducting cable skeleton, internal cold conduction is not affected, external cold conduction is not needed, and the compactness and the application environment applicability of the cable are improved.

The invention discloses a sports floor with moisture-proof and shock-absorbing functions and an installation technology thereof.The sports floor comprises a first moisture-proof film laid on a leveling layer, a plurality of parallel keels are erected on the first moisture-proof film, a plurality of shock-absorbing rubber mats are arranged between the keels and the first moisture-proof film, and the shock-absorbing rubber mats are arranged on the first moisture-proof film; and flame-retardant plates are fixedly installed on the upper sides of the keels, the laid keels are connected into an integral bearing frame by laying the multiple flame-retardant plates, a second moisture-proof film is laid on the upper sides of the flame-retardant plates, and a wood floor is laid on the upper side of the second moisture-proof film. Good elasticity, silence, moisture resistance and stability are provided, the construction cost is lower, and the environment-friendly requirement is met.

This invention provides a method for preparing shoe insoles using recycled thermoplastic elastomer materials, comprising the following steps: cryogenically pulverizing recycled thermoplastic elastomer foam to obtain a granular mixture, adding a polyurethane compatibilizer and mixing; heating and then transferring the mixture into a flatbed mold for pressing into a sheet; coating the surface of the sheet with a moisture-reactive polyurethane hot melt adhesive, and then bonding a mesh fabric; and finally, after static curing, punching out the shoe insole. The shoe insole prepared by this method can provide good structural strength while retaining the appearance of the crushed particles.
