Embodiment 1

[0044] A surface grinding and polishing process of a cathode titanium roller for raw foil manufacturing, specifically comprising the following steps:

[0045] (1) The titanium roller hanging roller that needs to be ground offline goes to the roller room for offline installation and grinding. The installation steps are as follows:

[0046] a. Clean up the debris in the grinding tank to ensure that the grinding oil is clean;

[0047] b. Install titanium roller and titanium roller bearing cover: add butter to the bearing before installing the titanium roller, then cover the bearing, and then tighten the screws;

[0048] c. Install the rotating chain: Shake the handle of the travel screw of the main drive of the titanium roller counterclockwise, tighten the chain, and tighten the base fixing screw with a 24X27 wrench;

[0049] d. Carry out all-round inspection: confirm that the rotating chain of the titanium roller and the screws of each part are fastened, the grinding oil valve ...

Embodiment 2

[0066] Different from Example 1, the grinding oil is prepared according to Table 5:

[0067] table 5.

[0068] Water-soluble organic grinding oil 80L pure water 20L

[0069] If there is no obvious roller surface damage or electric damage to the roller, fine grinding and water grinding are carried out in sequence. The grinding process for titanium rollers is shown in Table 6-7:

[0070] Table 6. The second process: grinding oil fine grinding process

[0071]

[0072]

[0073] Table 7. The third process: water milling process

[0074]

[0075] All the other are identical with embodiment 1.

Embodiment 3

[0077] Different from Example 1, the grinding oil is prepared according to the formula of Table 8:

[0078] Table 8.

[0079] Water-soluble organic grinding oil 120L pure water 20L

[0080] If there is obvious damage on the roller surface, coarse grinding, fine grinding and water grinding are carried out in sequence. The grinding process for titanium rollers is shown in Table 9-11:

[0081] Table 9. The first process: coarse grinding process of grinding oil

[0082]

[0083]

[0084] Table 10. The second process: grinding oil fine grinding process

[0085]

[0086] Table 11. The third process: water milling process

[0087]

[0088] All the other are identical with embodiment 1.

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...
