Product Details

Tianium anodizing rack

Product description:

Product shape and appearance:

Plate, rod, sheet, wire, mesh, tube, ring, ribbon, net basket and other specifications and any other shapes and sizes (can be designed according to user needs)

Technical characteristics:

(1) High oxygen evolution overpotential, high efficiency of non-oxygen evolution main reaction current;

(2) It is an insoluble anode with stable size and no pollution to the medium. The electrolytic equipment can work at a constant voltage for a long time without frequent adjustment;

(3) It can be regenerated after deactivation, and the substrate can be reused;

(4) The order of oxygen evolution overpotential of this product varies in different systems.

Application field:

Aluminum foil industry, sewage treatment industry;

Non-ferrous metal production and recycling;

Electrodeposition to produce copper, nickel and cobalt;

Electrolytic production of non-ferrous metals;

Chrome plating;

Surface electroless copper, nickel, zinc, tin;

Industrial electroplating, such as electroplating precious metals, electroplating Cr, Zn, etc;

Printed circuit board system;

Organic Electrolytic Synthesis;

Persulfate production;

Cyanide-containing wastewater treatment in electroplating plant;

Production and recycling of oxidants, such as perchlorate, iodate, chromic anhydride, persulfate, etc.

Examples:

Electrolytic extraction of metals in sulfuric acid solution, oxygen is precipitated on the anode, the choice of the appropriate anode material is a very important issue. Using tantalum-iridium-coated titanium electrodes, the oxygen overpotential is low, and it is not corroded by the electrolyte. The iridium oxide coating shows excellent electrolytic durability. The initial anode potential was 1.51V, after 6000 hours, it was 1.64V, and the coating weight loss was 0mg / cm2.

When using lead-based alloy electrodes (containing Sb6% ～ 15%, or containing Ag1%) in electrolytic production, the lead anode will dissolve, which consumes the anode material and affects the service life of the anode, and the lead dissolved in the solution will be on the cathode The precipitation increases the lead impurities in the metal and reduces the product quality.

The ruthenium-based coating will be seriously damaged under this condition, so it is not suitable for use. The initial anode potential was 1.48V. After 1000 hours, it rose to 2.0V and the anode has been passivated.

Precautions for use:

1. Prevent hard objects from scratching and scratching the surface coating during installation and use;

2. Take it out of the electrolytic cell when it is stopped for a long time, rinse the surface with clean water, and store it dry;

3. The higher the current, the stronger the acidity of the electrolyte, the frequent use of power off, the shorter the life;

4. According to the actual needs of users, automatic reverse charging can be designed;

5. Use in solutions containing fluoride ion, acetonitrile, acetonitrile methane, phenolsulfonic acid, thiourea, etc., will quickly damage the electrode.
