  • Patent number: 11078572
    Abstract: Method for preparing high-strength and durable super-hydrophobic film layer on inner wall of elongated metal tube includes roughening treatment of inner wall of a metal tube, electrodepositing preparation of nickel-phosphorus alloy layer and functional coating, heat treatment, subsequent anodizing and low surface energy modification. The method greatly reduces the influence of local mass transfer resistance, and a uniform nanocrystalline film layer is electroplated under the ultrasound induction. Since only electroplating solution is filled in the tube during the preparation process, the consumption of device and raw materials is greatly reduced. Also, since silica particles are added to the electroplating solution in preparing the nanocrystalline film layer, the surface morphology can be made more uniform and denser in terms of the microscopic morphology.

  • Patent number: 11001936
    Abstract: A rotational surface treating device with a high treatment efficiency that allows a treatment liquid to be discharged in a short time is provided. When a treatment bath 2 is rotated, parts 20 contact an electrode 50 to be electroplated. In this event, a plating liquid 16 is used as circulated by a pump P. The plating liquid 16 is discharged to the outside through a gap in a side wall 80 for replacement of the plating liquid 16 or the like. During discharge, the plating liquid 16 is not circulated by the pump P. The gap 8 which is formed in the side wall 80 is formed to be smaller than the minimum dimension of the parts 20 on the inner side. The gap 8 is formed to be wider toward the outer side.

  • Patent number: 10913669
    Abstract: A fluid treatment system is provided, comprising a capacitive deionization (CapDI) system for removing dissolved solids from a fluid. A controller is arranged in a closed feedback loop with the CapDI system to verify whether measured conductivity of the fluid corresponds to a set point conductivity value, and if the measured conductivity of the fluid does not correspond to the set point conductivity value, adjust the operation of the CapDI system to match the set point conductivity value. A pump selectively pressurizes the fluid such that purified fluid is at a pressure greater than line pressure of the fluid treatment system. An accumulator provided downstream of the CapDI system maintains the purified fluid at a pressure greater than the line pressure and intermittently delivers purified fluid to a use device. The purified fluid stored in the accumulator comprising chlorine and or chloramine so as to reduce microbial growth when stored in the accumulator.
