Single component liquid product for chemical coppering of wires for tyres and welding

In order to optimise the process, and therefore the final result, in the formulation of Cuprocond 67 L, inert surfactants have also been included, which allow a uniform adhesion reaction of copper, and antioxidant agents that limit the oxidation, due to atmospheric agents. The solution of Cuprocond 67 L must be simply added to water and heated to working temperature (40°C), and then corrected with sulphuric acid, up to the free acidity required by the specific line. The obtained copper layer is relative and proportional to the surface to which the chemical adhesion will occur: the smoother and cleaner the surface to be coppered, the better will be the resulting layer in terms of uniformity. Finally, there is the possibility, with the use of technologies to minimise waste proposed by Condoroil Stainless, to recover from the spent solution by-products having a certain commercial value, such as metal copper, sulphuric acid and ferrous sulphate and, moreover, to reduce the costs of waste water treatment and disposal of

IN the automotive industry the classic carbon steel wire was replaced around the 80s with copperised wire, exponentially improving the resistance and performance of the tyre itself; the copper layer binds to the special rubber of the tyre, consolidating the overall structure of the finished product. In the welding market the copper wire must have, besides the conductivity characteristics, a shiny aesthetic appearance. Currently for the preparation of the coppering solution, copper sulphate water and concentrated sulphuric acid are solubilised in water, leading to many inconveniences such as, for instance, superficial roughness increase, micro-crystalline embrittlement phenomena (causing physical properties variations) and iron increase in the solution limiting the duration of the coppering solution. For this purpose Condoroil has developed Cuprocond 67 L with the addition of corrosion inhibitors, which slow down the parasitic acid

Ceia induction heating systems

▲ ▲ The Ceia plant

For more than 30 years Ceia has dedicated itself to the design and construction of induction heating systems. High and medium frequency induction generators, control units, temperature sensors for temperature measurement and wire soldering alloy automatic feeders make up a line of equipment called Power Cube Family that can be used in industrial sectors where rapid, precise and repeatable heating of any type of metal is required. In particular, for companies that gravitate around the wire industry, Ceia is able to offer solutions that are claimed to maximise production, reduce energy consumption and certify the quality of the product. All Ceia systems can be used easily, stand-alone or integrated into automatic production lines. Each generator and controller can interface with any PLC via fieldbus. In addition, the V3 + master controller is equipped with a built-in data log and web server system that allows data storage for an appropriate process quality control.
