Abstract

The invention discloses a cathode titanium roller surface grinding and polishing technology for raw foil manufacturing, and belongs to the field of electrolytic copper foil technology preparing. The cathode titanium roller surface grinding and polishing technology comprises the following steps that firstly, preparing is conducted, a titanium roller is installed, an offline polishing and grinding machine is started, and the titanium roller runs and is flushed; secondly, grinding is conducted, the titanium roller is sequentially subjected to rough grinding, fine grinding and water grinding or the titanium roller is sequentially subjected to fine grinding and water grinding; and thirdly, polishing is conducted, the titanium roller ground in the second step is installed online, polishing is started, the polishing strength is 20%-50%, and polishing is conducted for 2-4 circles. Multifunctional and multipurpose electrolytic copper foil produced in the ground and polished cathode titanium roller electroplating process has the characteristics of being few in defect, fine in grain, low in surface roughness, high in strength, high in ductility and thinner, and is suitable for high-fineness electrolytic copper foil manufacturing.

Description

technical field

[0001] The invention belongs to the technical preparation field of electrolytic copper foil, and in particular relates to a surface grinding and polishing process of a cathode titanium roller used for raw foil production. Background technique

[0002] Electrolytic copper foil is the continuation of the crystal structure of copper ions on the surface of the cathode roller, and copper ions are electrodeposited on the titanium crystals, and thus grow into copper foil. The crystal structure of the surface of the titanium roller determines the crystallization state of the electrolytic copper foil. The surface finish of the cathode is high and the crystal grains are fine, so the electrolytically deposited copper layer is finely crystallized. The surface lattice size and shape arrangement of the cathode roller are different, the electrochemical properties, electrode potential and overvoltage are also different, and the electrochemical behavior between impurities an...
