COPPER ROTOGRAVURE CLYINDER

It's time I try to connect the topic article yesterday about the Copper Rotogravure / Coating.
The equipment needed for the coating process of the iron coated copper tubes, among others.
- A transformer that serves as a shock that would attach the copper tube to be coated iron roll.

- Body made of materials resistant to chemicals and strong weight-bearing terandung water in it, so it will not happen to leak or rupture tub, while the tub filled with water on a lot of volume. Water reservoirs amounts to 2 (two). A second later the tub filled with water that has mixed several different chemicals between tub 1 and tub 2
The first tub has a size of approximately 1 meter long, 2.5 meters wide with a depth of approximately 50 to 60 cm. and for a second bath having the same size but different length, which is about 2.5 to 3 meters

- Materials Chemistry, an important function in this coating process.

- Dinamo motor serves to rotate the cylindrical tube to be coated copper

Immediately, I try to discuss this coating process

1. Fill water tank with water (Must use tap water) because if you use ground water, will be a negative impact on the outcome of copper.

In a tub, mix water with chemicals and POTASSIUM COPPER Cyanide
In the tub 2, mix water with chemicals and copper sulfate and acid sulfate / H2SO4
Stir until evenly distributed, so each tub with a flat dissolved. Please keep in mind. between tub 1 and tub 2 content should not be mixed although only slightly,

After mixing these chemicals, then put the tubes to be coated and which have been cleaned. first dip tubes in bath 1 (the first), in a matter of time. after that when benar2 evenly, move the tubes are immersed in the bath tub 1 to 2.
Now in this second bath is a chemical coating process occurs, in addition to water containing these chemicals, like these two that will be hung lempengan2 copper plate will be eroded by itself and will be attached to move against the tabung2 iron, we can see it on video I attach before. Remember, this is done by running the motor armature which rotates continue tabung2 and provide the resulting shock process is carried out until the transformer would benar2 iron copper tube has been coated with sufficient thickness and not too thin, copper process could take a long time , approximately between 6-7 hours, depending on the strength of shock produced by the transformer and the approximate thickness of the layers as desired.
and for that I will try to discuss it further at the next opportunity.
