    摘要: An electrolytic cell comprising a walled enclosure including a cathode sidewall has busbar structure external to the cell. The busbar structure can include a gird bar releasably secured at the sidewall. It also may include a foraminous interface member between the gird bar and the sidewall, as well as have a small cathode busbar member on the sidewall. The small busbar member is typically located above and adjacent to the gird bar. Particularly when the gird bar and foraminous interface member are present, there can be internal support members for the cathodes directly secured to the inside face of the cathode sidewall. Furthermore, intercell connection may be handled directly to the outside face of the cathode sidewall. The overall structure can provide reduced potential for sidewall stress corrosion cracking, reduced cathode manufacturing cost, and accommodation of stress relief for the cathode weldment.

    摘要: A porous product, typically a metal foam sheet, is produced as a tailored, engineered product. The porous product can have enhanced strength, as well as more desirable electrical and mechanical properties. The product which first exists typically as a flexible, generally polymeric foam sheet in strip form, which strip is produced in the longitudinal direction, is stretched in a direction other than its direction of production. The porous product can have pores which would be anisotropic in form in usual production, which are stretched to at least substantially isotropic form. The product can even be tailored to have pores which are anisotropic in the direction of the stretch. Thus, an engineered product can be produced which, for example, as an open-cell metal foam prepared from a polymeric foam can have conductivity, both thermal and electrical, as well as strength and ductility, tailored for greater uniformity and performance.

    摘要: Electrodes in plate form can be electrocatalytically coated and secured to a current distributor, such as by welding to a base plate, and may be serviceable, e.g., as anodes, in cells electrolyzing brine. Recoating of plate electrodes can require removal from the cell, removal of old coating, application of fresh coating, then returning and securing the freshly coated electrodes to the cell. There is now provided a covering innovation for the original electrode plates. In the covering innovation, the original plates do not need to be separated from a base member of the cell. In the method of covering, there is utilized an outer envelope member, tightly engaging the original plate electrode. The envelopes can have an electrocatalytic coating on their outer surfaces. The resulting electrodes are thus a combination of an old inner plate and a new outer envelope, with an outer surface coating on the envelope. The envelopes can be secured to the inner plate and/or to a current distributor such as a base plate.

    摘要: A metal surface, useful as an electrode in an electrolytic cell, is now described having enhanced adhesion of subsequently applied coatings combined with excellent coating service life. The substrate metal of the electrode, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching and melt spray application of metal or ceramic oxide to ensure a roughened surface morphology. Usually in subsequent operations, a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.

    摘要: Methods, and various apparatus therefor, are disclosed for the electrolytic treatment of an acidic solution. Generally the method comprises: (a) providing an electrolytic cell, the cell comprising: (i) an anode chamber and an anode therein; (ii) a cathode chamber and a cathode therein; and (iii) a diaphragm. Usually the diaphragm is of a non-isotropic fibrous mat comprising 5-70 weight percent organic halocarbon polymer fiber in adherent combination with about 30-95 weight percent of finely divided inorganic particulate impacted into said fiber during fiber formation, the diaphragm having a weight per unit of surface area of about 3-12 kilograms per square meter. The method can continue by (b) introducing the acidic solution into the cell; (c) impressing a current on the anode and the cathode causing the migration of ions through the diaphragm; and (d) recovering a product of the electrolytic treatment from the anode chamber, or the cathode chamber, or from both chambers. In one method, the acidic solution is a cell bath circulated to the anode chamber, while rinse solution downstream of the cell bath is circulated to the cathode chamber. The method, and apparatus therefor, are particularly applicable to the recovery of hexavalent chromium from a dilute chromium electroplating rinse solution.

    摘要: A cathodic protection anode assembly for metal structures in water is now provided with highly desirable rugged construction. The assembly is particularly useful for providing cathodic protection utilizing an anode, in submersed condition, on one side of a structure while having an assembly protruding through an opening in the structure with a connection at the back side of the structure to a lead-in cable. Such structure may have the back side in ambient air. For the back side structure, the assembly has a highly desirable leak resistant characteristic. Moreover, the assembly can provide efficient low contact voltage at the anode and cable connection.
