Platinised Titanium Sheet and Mesh Anode and Titanium Connecting Fasteners

February 10, 2020 at 4:17 PMPlatinised

Tiaano manufacturing different sizes and Shapes of platinised Titanium Electrodes for water ionizers. The essential components of the ionization chamber are its two collecting electrodes, (the anode and cathode) the anode is positively charged with respect to the cathode.

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 the current 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, therefore one of the chambers will have acidic water while the other will have alkaline water. The alkaline water is for drinking purpose, whereas the acidic water is for disinfecting or sterilizing purposes.

Most good ionizers on the market use electrodes made of platinum plated titanium. Titanium will not dissolve in your ionized water as the cheaper metals like stainless steel does. The ionizer uses grade 1 titanium (as per ASTM Standard) electrodes to be plated with a good electrical conductor. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a  few years.

Benefits of Platinised Titanium Anodes over Lead Anodes for Hard Chromium Plating

January 31, 2020 at 2:57 PMPlatinised

Long life, dimensionally stable and easily fabricated into any shape:  When used in the plating process, dimension of the lead anodes are changing due to the loss of the lead oxide which is formed on  the anode during operation - it leads  surface area is getting collapsed . Also larger lead anodes can lengthen under their own weight.  Whereas titanium anodes are dimensionally stable throughout their operating life and can easily be manufactured, even in complex shapes and lengths, up to 4m. Consequently, shaped anodes can be manufactured very accurately to allow consistent plating to small tolerances, often making a further honing step unnecessary.

Homogeneous and long-lasting active surface: When lead anodes are not in use the lead oxide layers change to lead sulphate and lead chromate, which are not good conductors and consequently do not perform consistently. Platinised titanium anodes operated correctly, remain deposit free and therefore perform constantly well throughout the whole anode life.

Energy savings with shaped anodes and small anode/cathode distances: Small electrode gaps reduce electrical resistance losses in the plating bath and produce energy savings. In the case of lead anodes, which cannot be formed as accurately as a mesh, resistance losses result in bath heating, requiring further energy for cooling. Therefore, platinised titanium anodes can provide energy savings both in heating and cooling which, in turn, allows the plating chemistry to be easier to manage and maintain.

Reduced environmental burden and reduced maintenance: No chemical cleaning or brushing of passivated areas is necessary. Bath life is increased as there is no formation of lead sludge - lead anodes produce about 3g of lead sludge for every 1kg of chromium deposited in sulphuric acid type baths and even higher in other baths. Furthermore, the reduced resistance losses and subsequent need for cooling allow for easier maintenance and control of the plating chemistry.

Mesh anodes provide excellent throwing and can be used at high current densities: In electrolysis, corners and edges are preferred reaction sites; an expanded mesh has edges evenly distributed across the anode surface, thus producing uniform current density and excellent plating results. Large area mesh anodes improve throwing power and the mesh structure allows good solution movement and electrolyte exchange and plating with high current densities.

Easier handling and recoating: Positioning of lead anodes for optimising chrome plating is often awkward due to their weight, whereas spot welded or bolted mesh anodes are very light by comparison and allow safer and easier handling. Furthermore, they can be easily removed and / or replaced whenever necessary. This often allows a re-use of expensive anode materials and designs, and reduces operational costs. 

Considerations when converting from Lead to Platinised Titanium anodes:

Where platinised titanium anodes are used as a replacement for lead anodes consideration must be given to several factors to ensure that the technology is utilised to its full potential – a change in plating process is necessary and, as such, the whole plating set-up and its costs need to be considered to maximise the return on the investment in these anodes.

Consideration should be given to:-

Thorough cleaning of the plating tank and associated equipment with an adjustment of the residual lead concentration.

Bath/Electrolyte composition and operating conditions.

Current Density and operating Voltage.

Anode design.

The service life of platinised titanium depends on both the electrolyte matrix and the applied current density. Therefore, in fluoride containing baths and at current densities >75 A/dm2 platinised niobium is recommended in preference to platinised titanium.

Platinised titanium and niobium anodes are completely or partially covered with a fee microns of platinum (usually 2.5µm). Where the platinum is consumed after years of use, the underlying titanium or niobium passivates and the bath voltage rises at constant current operation. The base metals are not attacked at the usual operational voltages, in fluoride free chromium baths.

For most applications the platinum wear rate is very low and the corresponding anode life time high. In sulphuric acid chromium baths the platinum consumption is between 1g and 4g platinum per million amp hours. Careful design of the platinised anodes will increase their benefit and maximise their life span.  

Summary: Platinised titanium anodes provide a cost effective replacement for lead anodes in hard chromium plating. They provide superior quality deposition and consistency resulting in increased productivity and throughput. Cost benefit analysis demonstrates that the higher initial investment in this technology can be recouped within a short period of time.

 

Platinised Titanium Anode and Platinised Titanium Cathode or Titanium Cathode for Water Ioniser or Alkaline Water Application

January 24, 2020 at 5:49 PMPlatinised

Tiaano manufacturing different sizes and Shapes of platinum or platinised anode for water ionizers. Water Ionizer Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, expanded mesh, pipe,  rod and custom built. 

The best water to drink is alkalized or ionized water, which is produced by running normal tap water over a positive (platinized anode) and a negative (platinised cathode) electrode. This creates positive and negative ions in the water that are then separated creating two different waters, one that is alkaline and one that is acidic.

Alkaline water is for flushing out internal toxins, scavenging free radicals, and oxygenating the body. Acid water, which is really a by-product of ionizing water, can be used externally for cleansing the skin, cleaning any surface and feeding your plants.

Platinum Plated Titanium Expanded Mesh Anode for Electro Plating Industry

January 24, 2020 at 4:30 PMPlatinised

Tiaano Platinised Titanium Anodes are most suitable for electro plating of precious metals like gold, platinum, palladium, chromium, nickel, rhodium and copper etc…

Platinised titanium anodes consist of a titanium base, in the form of either expanded mesh, sheet, rod, wire or tube with a plating of platinum between 2 to 5 microns thick and purity of platinum is 99.99%. They possess the electrochemical properties of platinum. The titanium used is 99.9% pure as established by ASTM (American Society of Metal).

The service time of the platinised titanium anodes depends on the chemical resistivity of the base metal, the dissolution rate of the deposited platinum in the electrolyte, which in turn depends upon layer morphology, and adhesive qualities, pH, current density and current ripple.For most applications the dissolution rate is low and the advantages of platinised titanium anodes are far greater than any metal loss.

Advantages of platinized Titanium Anode:-

•          Long operating life; maintenance-free.

•          Economical due to low platinum requirements.

•          High dimensional stability and load resistance.

•          Good current distribution.

•          High corrosion resistance.

•          Low weight.
