Description
Technical field
The present invention relates to technical field of copper foil production, and in particular to a kind of cleaning of the hard state copper foil of short route.
Background technology
, it is necessary to which carrying out cleaning treatment to copper foil finished product can cut after the completion of the rolling of hard state copper foil finished product.Tradition
For hard state copper foil cleaning product line comprising unreeling → sewing machine → 4S jockey pulleys → degreasing case（Cleaning by degreasing）→ squeeze roll
→ cold water flush → squeeze roll → pickling tube → squeeze roll → cold water flush → abrasive material brush box → cleaning brush box → squeeze roll → heat
Water flushing → passivation → squeeze roll → drying baker → 4S jockey pulleys → winding, production line length reaches 50 meters or so, tension range 0
→ 10KN, easily produces broken belt, and cleaning process length, the production space of occupancy are more, energy-output ratio is big, copper foil in cleaning process
Need by multiple tracks squeeze roll and brush box, copper foil surface, which is easily produced, after cleaning stencils.
The content of the invention
The present invention provides a kind of cleaning of the hard state copper foil of short route, and not only cleaning performance is good, and can effectively shorten copper
The production procedure of paper tinsel cleaning, reduces production space-consuming, while can also substantially reduce energy consumption, improves the copper foil after cleaning
Surface quality is good, and copper foil is not likely to produce broken belt in cleaning process.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of cleaning of the hard state copper foil of short route, extremely
Comprise the following steps less：Copper foil after unreeling sequentially passes through the first fermentation vat provided with agent for carbon hydrogen detergent, provided with agent for carbon hydrogen detergent
Second fermentation vat of the mixed liquor constituted with passivator, winding, the agent for carbon hydrogen detergent include the molten oiliness that flash-point is 40-90 DEG C
Solvent and nonionic surfactant.
Further, the copper foil is at the uniform velocity by first fermentation vat and second fermentation vat and in transmit process
Complete cleaning.
Further, the molten oil-based solvent accounts for quality≤90% of the agent for carbon hydrogen detergent, the non-ionic surface active
Agent accounts for quality≤15% of the agent for carbon hydrogen detergent.
Further, the agent for carbon hydrogen detergent includes ethyl propionate and APES.
Further, the agent for carbon hydrogen detergent is by 85wt% ethyl propionate and 15wt% APES group
Into.
Further, the quality of the passivator accounts for the 0.1%-0.12% of the mixed liquor quality, the agent for carbon hydrogen detergent
Quality account for the 99.88-99.9% of the mixed liquor quality.
Further, the passivator is filed for the nitrogen of benzo three.
Further, soak time of the copper foil in first fermentation vat and second fermentation vat is no less than
5s。
Further, the copper foil comes out it before first fermentation vat is entered and from second fermentation vat
Be additionally provided with the copper foil afterwards makes it prevent the first tensioning operation and the second tensioning operation of fold from belt tension by jockey pulley.
Further, described unreel is additionally provided with upper a roll of copper foil and lower a roll between operation and first tensioning operation
The suture operation that copper foil is sutured and makes the afterbody of a roll of copper foil and the head of lower a roll of copper foil be connected.
After above technical scheme, the present invention has the following advantages that compared with prior art：
1st, traditional copper foil cleaning process is needed by multiple tracks brush box, and surface stencils very heavy after cleaning, and passes through present invention cleaning
Copper foil afterwards remains bright and clean, the exquisiteness of preceding working procedure roller surface, and surface quality is good.
2nd, production procedure being substantially reduced using the production technology of the present invention, production line length is only original three/
One, occupancy production space is few, and greatly reduces energy consumption.
3rd, it is very good using agent for carbon hydrogen detergent cleaning copper foil deoiling effect, and volatility is moderate, can be by copper foil surface
It is very thorough that ROLLING OIL is removed；And because agent for carbon hydrogen detergent has moderate volatility, so without using squeeze roll can
Copper foil surface is kept to dry, relatively original cleaning is greatly simplified.
4th, about 50 meters of traditional cleaning machine group length, centre is related to multiple tracks squeeze roll and brush box, cleaning thickness≤
Easy broken belt during 0.06mm copper foil；Using cleaning unit of the invention, not only flow is short, and eliminates squeeze roll and brush box
To the polish-brush of copper foil surface, broken belt is difficult.
