Abstract
Provided is a steel belt electroplating process for a Bundy tube. According to the steel belt electroplating process for the Bundy tube, cyanide copper pre-plating is mainly adopted, and then sulfate acidic copper plating is carried out. An obtained Bundy tube copper coating is fine and uniform, so that manufacturing of the Bundy tube is facilitated; and through a designed S-type electroplating method, the production space is saved, investment cost is reduced, and accordingly profits are increased.
Description
Technical field
Bundy tube steel band electroplating technology, is specifically related to the technical field of continuous steel strip electroplating.
Background technology
What Bundy tube was mainly manufactured by steel band copper facing, it is commonly utilized in automobile oil pipe, floor heating pipe, air-conditioner pipe etc.
Aspect.Cyanide electroplating can obtain the good coating of fine and close, smooth, adhesion, so continuous copper-plating of steel strip uses cyanide electroplating
Technique, although the clearly superseded cyanidation technology of country, but the technique of replacement is not found till now, and because it is widely used in essence
The fields such as close electronic instrument, precision instrument, Aero-Space, can only delay to eliminate.Cyanide electroplating is most widely used, earliest plating
Copper method, but cyanide electroplating can cause that the adhesion of coating is bad because phosphorus content is higher, the easy sealing-off of coating surface, in system
Local corrosion phenomenon is easily caused after into Bundy tube.Not only causing the Bundy tube after the waste of resource, and corrosion can cause gas
The seepage of body, liquid etc., during conveying flammable explosive gas liquid or toxic gas, can cause huge to the safety of staff
Harm, and environment is polluted, do not meet the principle of the environmentally friendly production in the world today.By substantial amounts of experiment table
Bright, phosphorus content is few in acidiccopper plating, can combine coating even closer, is difficult sealing-off, can effectively economize on resources, and protects
The safety of shield personnel, while meeting current green production principle.
According to documents, it is necessary to multiple copper plating grooves, auxiliary tank and other auxiliary set in original continuous copper-plating of steel strip
Standby, continuous copper-plating of steel strip production line is up to 80 meters, and floor space is big, every meter of about 20,000 yuan of steel strip production line, one-time investment
Too big, comprehensive production efficiency is low, it is necessary to the attended operation of extensive work personnel, causes the waste of financial resource and material resource.Steel originally
Band copperizing continuously typically can only once electroplate one or two steel bands, and in present invention, steel band is in preceding treatment groove and coating bath
All it is S-type trend, greatly reduces floor space, saves production line cost about 1/2nd, and because containing in acidiccopper plating
Phosphorus amount is few, can combine coating even closer, and the Bundy tube of making is difficult sealing-off, can effectively economize on resources, and protects people
The safety of member.
