Among the present invention, the prescription of degreaser is: sodium hydroxide 20g/L, yellow soda ash 20g/L, sodium phosphate 50g/L and water glass 10g/L.
Among the present invention, need carry out at normal temperatures electrochemical degreasing in the time of use.
Among the present invention, adopt the 8V rectifier power source in the time of use, copper strips connects (-) utmost point, and degreaser connects (+) utmost point.
Among the present invention, the oil removing time is minimum to be 10s.
Among the present invention, the structure of employed copper strip deoiling device should satisfy following requirement during oil removing: with rectifier power source; The clad welded production line of different travelling speed all should make copper strips move at least 10s in degreaser; During production line stop, copper strips leaves degreaser automatically; Clean immediately and dry up after the copper strips oil removing.
The present invention adopts alkaline degreaser.For example, sodium hydroxide 20g/L, yellow soda ash 20g/L, the solution that sodium phosphate 50g/L and water glass 10g/L are made into, the pH value is 13～14.Adopt the 8V rectifier power source, copper strips meets (-), and degreaser meets (+).After copper strips after the oil removing cleaned in clear water, the water on surface was not assembled and is the globule, but evenly spread out wetting, show deoil respond well.
Because the strong basicity degreaser has oxygenizement to copper strip surface, if copper strips storage period in this degreaser is long, will make the surface oxidation variable color.
Oil removal plant is placed a copper strips transit box made of plastic by a degreasing tank that be welded into mild steel plate, that be placed with degreaser in groove, be provided with a plurality of rollers in the case, to transmit copper strips.The base plate of this case has than multiple hole, and is located in the degreasing tank by spring support in four corners of base plate.The side plate of transit box is connected with lever with electromagnet armature.By the combined action of spring and electro-magnet, transmission case body is moved up and down in degreasing tank.When in the magnet coil during making current, armature drives lever and moves down, and makes the spring-compressed of copper strips transit box bottom and enters and carry out oil removing in the degreasing tank.After the magnet coil outage, under the effect of case bottom spring, copper strips transit box item is risen, make copper strips leave degreaser.In order to improve deoiling effect, accelerate in degreasing tank, to be provided with the rectifier power source of 8V, in order to carry out electrochemical degreasing except speed oil.Copper strips after the oil removing enters in the Rinsing Area and cleans, and dries up with hair drier immediately after the washing.
