Electroplating in the home is its most important component

Probably, there is no home master,which would never have to cover the hand-made objects with a layer of zinc, chromium, copper or nickel. These coatings not only give the metal objects a beautiful appearance, but also provides an opportunity to protect them from the influence of the environment, as well as to give the product properties that were not previously inherent in it.

The activity that allows to apply a thin layermetal on the surface of the product, which helps protect the latter from corrosion and give it decorative properties called electroplating, and in simple speech, electroplating. Electroplating at home is quite common in our country, because after having equipment for galvanizing at home or in the garage, everyone can personally chrome, zinc, copper plating, nickel plating of any metal products.

Of course, home electroplating involves the availability of certain equipment, as well as knowledge in the electrochemical field - without this, in the case of coating with the help of electrolysis is indispensable.

One of the main components thatto own every electroplating in the home is a galvanic bath. Below, one of the ways of manufacturing it will be considered. Everyone who has decided that he needs a galvanic at home, have to deal with the problem of how to make a galvanic bath or adapt it for any capacity.

So, there is one inexpensive solution to thisissue. Many companies selling chemicals use special polyethylene containers. Each such capacity is crocheted and strengthened on pallets. It is this capacity that is to be obtained for use as the basis of a galvanic bath.

After the container is delivered and installedit is necessary to carefully cut off its upper part. Cut off part is still useful - it will be made of a bath cover. From the ends of the bath, three holes are made, into which the anode rods will be installed. Of course, the holes should be on the same level.

The lid at the galvanic bath should becertainly. Later it is screwed to the bath, using a loop, for example, a piano. For sealing, which must be ensured between the lid and the bathtub, rubber seals for car doors are perfect - they are sold in any car dealer and must be planted around the perimeter of the side of the bathtub. After installing the cover, it should fit snugly against the sides of the bath.

Thus, a bath with an opening lid is obtained, which in turn has a filler opening, which is recommended to be used to connect the ventilation hose.

In the previously made holes in the sidescopper bars are inserted. In their quality, copper tubes with a suitable diameter of 20 mm can be used. In the event that the tube does not have sufficient rigidity, a steel rod is inserted inside. The ends of the tubes must be flattened, and then drilled into them holes, to subsequently connect them to the rectifier.

In conclusion, let us give an example of the stages of one of the processes that can be performed in the above-described bath-galvanizing bath. These stages are:

- Degreasing the product in an organic solvent;

- Chemical degreasing in a solution of alkali;

- Wash the product in hot water;

- Electrochemical degreasing in alkaline solution;

- Wash in hot water;

- Wash in cold water;

- Activation or etching;

- Directly by galvanizing;

- Lightening with a weak solution of nitric acid (optional);

- Passivation;

- Wash in cold water;

- Wash in warm water, temperature around 40 ° C, but no more;
