Advantages of Platinised Titanium Anodes in Jewelry Gold Plating (Common for Electro Plating):-

1. The anode size is stable, and the distance between the electrodes does not change during the point solution process, which can ensure that the electrolysis operation is performed under the condition that the tank voltage is stable.

2. The working voltage is low, so the power consumption is small, the power consumption can be saved, and the DC power consumption can be reduced by 10% to 20%.

3. Lower capital and long Life: The working life of titanium anode is long. The anode life has reached more than 6 years, while the graphite anode is only 8 months.

4. It can overcome the problem of dissolution of graphite anode and lead anode, avoiding pollution of point solution and cathode product, thus improving the purity of metal products

5. Can increase the current density. When electrolysis is carried out at a high working current density, it is preferred to use a titanium anode.

6. Avoid the short circuit problem after the lead anode is deformed, thus improving the current efficiency.

7. Titanium anodes are light in weight and reduce labour intensity.

8. Low over potential characteristics, the surface between the electrodes and the bubbles of the electrodes are easily eliminated, which is an important reason for the voltage drop of the metal anode electrolytic cell.

9. Corrosion Resistance: Platinised Titanium Anodes protective to different surrounding conditions and are also resistive to corrosion. They can be resistive to moisture and steam and also to the corrosion due to oxidation and reduction. They can also withstand easily under the attack of acids and other chemicals. They can also resist the adverse effect occur at extremely high temperature.

10. Stability: Platinum is one of the noble group of metals and also precious metals, all of which are excellent catalyst materials. Platinum is conductive, chemically stable and highly resistant to oxidation and corrosion.

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.

What is Electroplating?

Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Electroplating is often applied in the electrical oxidation of anions on a solid substrate like the formation of silver chloride on silver wire to form silver chloride electrodes.

Electroplating is majorly applied to modify the surface features of an object (e.g corrosion protection, lubricity, abrasion), but the process can also be used to build thickness or make objects by electroforming.

The Anode and Cathode

In electroplating practice, the current is usually introduced from an external source and the anode (Platinised Anode) is the positive electrode and cathode is a negative electrode. The cathode is the electrode where the electrochemical reduction reaction occurs. The anode (Platinised Anode) is that where the electrochemical oxidation reaction occurs.

The electroplating process uses an anode (Platinised Anode) and a cathode. In electroplating, the metal dissolved from the anode can be plated onto the cathode. The anode is provided with direct current, oxidizing and dissolving its metal atoms in the electrolyte solution. At the cathode, the dissolved metal ions are decreased and the metal is placed on the product. That is called Electro Plating process.

The key factor for a quality water ionizer is the material of the electrodes (Platinised Anodes and Platinised Cathodes). Most good ionizers on the market use electrodes made of platinum plated with grade 1 titanium. Titanium will not dissolve in your ionized water.

How does an alkaline water ionizer work?

A water ionizer works on the simple principle of electrolysis. Any type of water ionizer has two electrodes put into a container having two chambers separated by a semi-permeable membrane. The two electrodes – positive and negative, are put into two separate chambers and current (4 Volt per cell) is passed through them. Ionization process takes place on passing of the current through the electrodes. The dissolved minerals get attracted either to the positive or negative electrode and gets stick to their surfaces. Thus one of the chambers will have acidic water while the other will have alkaline water. The alkaline water is for consumption purpose, whereas the acidic water is for disinfecting or sterilizing purposes.

Anode Side: Platinum Plated Titanium Anode

Positively charged ions gather at the negative electrode to create reduced water, which concentrates available alkaline minerals, such as calcium, magnesium and potassium from the source water. This alkaline ionized water is drawn for drinking and cooking, through the main stainless steel spout.

Cathode Side: Platinum Plated Titanium Cathode

Negatively charged ions gather at the positive electrode to make oxidized water, which concentrates acid minerals such as nitrates, sulfides, chlorides, and fluorides from the source water. This acid ionized water has a myriad of external uses. It is discharged into the sink.

Platinum is a precious metal having very good physical and chemical properties. Tiaano manufacturing and supplying platinized anodes are widely used for electroplating and electro winning industrial applications. Electroplating is used in a variety of industries for coating metal objects with a thin layer of a different metal. This electrochemical process requires anodes. There are as many types of anode compositions as there are applications. Platinized Titanium and platinised Niobium Electroplating anodes offer numerous benefits.

Electroplating anodes are used to create products in many industries, including the hydraulic industry. The most common uses for electroplated products are chrome-plated oil pump auger flights, hydraulic cylinders, conveyor flights, sheets and tanks where it would be impractical or too expensive to make the item entirely out of the plating metal.

What is Electroplating?

Electroplating is used to coat certain metals with a thin layer of a pure metal, like silver or gold, copper, zinc or any of several alloys. During the process, an electric current passes through a solution known as an electrolyte. The composition of the electrolyte depends on the desired coating. The item being electroplated (cathode) is immersed into the electrolyte solution, as is the plating anode. The two are then connected to an electrical current source, by connecting the positive end to the plating anode and the negative to the item being to be plated. Once current flows through the system positively charged metal ions become attracted to the negatively charged item, thereby coating the item with the desired finish.

The various field are using our platinized metal Anodes for Chrome Plating, Wheel Chrome Plating, Chrome Plating Kits, Alloy Chrome Plating, Plastic Chrome Plating, Nickel Plating, Gold Plating, Silver Plating, Silver Coating, Chrome Plating Bath, Nickel Plating Bath, Bright Chrome Plating, Bright Nickel Plating, Plating Service, Tin plating, galvanized, anodized, corrode protection etc…

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…

The Platinised Titanium electrodes create the ionization, the electrode cell is the heart of an ionizer. It consists of a series of electrodes (plates), each separated by a membrane. The Platinized Titanium Mesh Anode is mostly used, because it has outstanding practical performance, such as strong ability of ionization release, good exchange of electrolyte, close structure and light weight, etc.

Titanium is non-soluble and stable in water. It will last for many years [20, 30 or more] without corroding. Its durability, strength, and non-toxicity make it the choice of material to doctors and medical scientists use for their implanted medical devices such as artificial joints and pacemakers. Also, because it’s so durable and non-magnetic it makes it the best choice of metal to construct a water ionizer electrode.

Platinum is a catalyst, and is needed to speed up the electrolysis. With the water ionizers changing the water so drastically just by passing the water over the electrodes, the ionization process wouldn’t occur without a speeder-upper.

Platinised titanium anodes are very frequently used as expanded mesh anodes due to their excellent practice characteristics of high throwing power, good electrolyte exchange, compact construction, low weight etc.

The generation of electrochemical oxidants for use in water treatment in industrial plants. Not only are our anodes used in industrial waste water treatment, but they are also used in applications such as process water treatment, the treatment of potable water, water disinfection (for use in the food industry) and extreme water disinfection. The great advantages of this electrolytic generation of oxidants are the ease with which they are handled and most importantly the reliability of the oxidants produced. Platinised Titanium Anodes involve the treatment of waste water containing inorganic contaminants, such as cyanide and nitrates. Different products are yielded from this electrolysis depending on a number of factors, including pH.

Basic Principles of Electrocatalytic Oxidation Technology

The mechanism of the electrocatalytic oxidation process for organic wastewater treatment is to degrade the organic matter directly through the high potential and high catalytic activity of the anode surface or through reaction between the strong oxidants made by the anode surface (such as H2O2, • OH, ClO-, etc.) and toxic organic matter, and further degrade the toxic pollutants in wastewater.
