PLATINIZED METAL ANODE FOR ELECTRO PLATING

May 3, 2020 at 10:41 PMPlatinised

Platinised Titanium Anodes are exclusively used in the Electro Plating Process. Tiaano Electrodes has the technology to platinum titanium substrates in the form of plate, wire, rod, tube, plate and mesh. Furthermore, we have the ability to manufacture complex fabricated anodes. The external surface of all platinised titanium anodes is essentially pure platinum which exhibits all the normal characteristics of the wrought metal as far as corrosion behaviour is concerned. The secret of the quality of a platinised anode lies in the nature of the interface between the platinum and the titanium. It is well known that normal untreated titanium presents a very inert and intractable surface when it comes to applying precious metal coatings. That this problem was overcome to an adequate extent is demonstrated by the wide acceptance of platinised titanium anodes in different industries throughout the world. Although there are still many platinum electroplated anodes produced without an adequate interlayer, they are used for less demanding applications.

What is Electroplating?

Electroplating involves passing an electric current through a solution called an electrolyte. This is done by dipping two terminals called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply. The electrodes and electrolyte are made from carefully chosen elements or compounds. When the electricity flows through the circuit they make, the electrolyte splits up and some of the metal atoms it contains are deposited in a thin layer on top of one of the electrodes—it becomes electroplated. All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead.

Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which power supply produce electric currents. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.

PLATINIZED ANODES – TIAANO MANUFACTURER AND SUPPLIER OF PLATINISED TITANIUM ANODES AND PLATINIZED NIOBIUM ANODES

April 10, 2020 at 9:38 PMPlatinised

Platinized Anodes (Pt. Anode) are produced by plating platinum (Pt) on a specially treated precious metal (Titanium / Niobium) by means of electro deposition process. They are economical as well as it retains the superior physical and chemical properties. There are many advantages as below.

General advantages for Titanium Anode with Platinum Plating or Platinised Titanium Anode:-

1.         Titanium gives corrosion resistance in most electrolytes. Titanium itself will act as a conductor of current without passing current into the electrolyte.

2.         With the application of a thin layer of platinum onto the titanium surface the current will pass along the titanium and enter the electrolyte through the platinum surface with the exposed surfaces of the titanium remaining inactive. The platinized area of the anode will operate at current densities of up to 100 amperes per square ft. of surface area.

3.         The electrical resistance of titanium is high and where solid rods or plates are used it is essential to design with adequate cross sections of titanium and with the shortest current paths to the platinum surface, thus avoiding high volt drops.

4.         Where long lengths of platinized titanium are required to improve the electrical resistance, titanium is formed over copper and the platinum skip-plated onto the titanium. This provides the most economic installation with the best relationship between current density and volt drop.

5.         It is recommended that rectifier 3 phase AC is used and the voltage between anode and electrolyte should be less than 10 volts.

Platinized titanium anodes are suitable for used in impressed current system for jetties, pipelines protected by deep well ground beds, power stations and water storage tanks. Also the major application of Chlorate & perchlorate production, Eectro-chlorination, Electroplating, Sewage treatment, Electro synthesis, Electro Chlorination, Water Treatment, Water Ionization, Waste Water treatment, Sewage Treatment, Effluent Treatment etc…

Customized Electrode Production with Pure Platinum Plating on Titanium or Niobium

Platinum-titanium insoluble anodes are based on titanium metal as anodes in the form of sheets, plates, rods, filaments, and tubes. The thickness of the standard platinum layer is 2-5µm. Under higher requirements, the thickness of the platinum layer can reach 20µm. The service life of the platinum-plated titanium anode depends on the working medium (electrolyte) and the current strength (current density) of the anode. The current density should not exceed 75A / dm2. Below this value, the wear of the platinum layer is very small, and the service life of the anode can also be estimated. According to experience, the wear of the platinum layer is about 1-4 grams per million amp-hours in a fluorine-free chromium plating solution.

 

Titanium anode is mainly used in industrial production such as chlor-alkali and sodium hypochlorite, electrolytic synthesis of organic compounds, sewage treatment, seawater desalination, electrolysis of dilute brine, anode for sodium hypochlorite, anode for sodium chloride electrolysis, disinfection of tap water, series of electrode products for sewage treatment, seawater desalination Electrodes, elimination of plankton in industrial circulating water, etc. The main categories are: platinum titanium electrode, titanium electrode, super titanium electrode, noble metal plating electrode group.

 

The platinized anode is characterized by its three outstanding effects as an electrode material:

1. It is stable, corrosion resistant and can be used in various media.

2. For the oxygen evolution reaction, the over potential is very high

3. For the hydrogen evolution reaction, the over potential is very low.

PLATINISED TITANIUM SLOTTED ANODE FOR ELECTRO CHEMICAL PROCESS

March 30, 2020 at 4:51 PMPlatinised

Electrochemical process requires anodes. Mainly Platinized Titanium or Platinised Niobium Anodes. Platinised titanium anodes combine the excellent electro chemical characteristics of platinum with the good corrosion qualities of titanium.

Platinised titanium is titanium that has been plated / coated with a very thin layer of platinum, normally by electro deposition process. The purpose of it is to provide a conducting medium that will not react with electrolytes. Platinum is very inert and doesn't readily react electrochemically, so you can do some very good electrochemistry with it. Titanium is used because of its high conductivity and ease in plating under electro deposition process. Furthermore, if the platinum is porous and the titanium is exposed, the titanium will passivate and soon stop interfering with any electrochemistry going on at the electrode.

Titanium - activated by a platinum or a mixed metal oxide (MMO) layer with semiconducting properties - forms an insoluble anode. Both types of anodes are widely used for very different electrochemical applications (electro winning, electro synthesis, electro analysis, electroplating (mainly Automobile parts plating anode, Copper foil plating anode, Hard chrome plating anode, Rotogravure cylinder plating anode, Chromium plating anode, Wire plating anodes, Copper plating anodes, Gold plating anodes, Nickel plating anodes) cathodic corrosion  protection (ICCP) (Mainly seawater and limited space area), disinfection (mainly Electro Seawater Chlorination, Ionization) Gray Water Treatment, Sewage Treatment and waste water treatment, Effluent Treatment and others). The property of titanium to passivate when anodically polarized is the reason for its use as anode base. The activation must be corrosion-resistant against the electrolyte and must remain active.

Tiaano suggest the platinized Titanium anodes for electro Chemical process because of its advantages like complex shapes is possible, Long lifetime, Easy maintenance, High dimensional stability and loading capacity, Good corrosion resistance, Low weight, Perfect current and distribution, Replatinizing with crediting of residual platinum etc…
