Then it is cleaned with clear water；The Passivation Treatment be metal raw sheet and the insulation board that is secured to are immersed 0.5wt%~
In the potassium bichromate solution of 1wt%, at 35~42 degrees Celsius, the time is 10~15 minutes for temperature control, makes the table of metal raw sheet
Processing is rinsed with clear water after face generation oxidation film；
(3) the metal raw sheet after Passivation Treatment: being put it into electroplating bath the direct current of logical 8V~12V by electroforming, adjusts electric current
Density is 8~12A/dm2, and the electroforming of circumferencial direction is carried out to its inner surface, control reflecting mould with a thickness of 0.4~0.5mm,
After electroforming, power supply is closed, metal raw sheet is taken out out of electroforming tank, is cleaned with clear water to remove the slot on its surface
Liquid, it is careful to remove the resulting reflecting mould of electroforming, the further tidiness rinsed to guarantee its surface is carried out to reflecting mould,
Then the reflecting mould after flushing is dried and flattened using drying equipment, and is cut by required size.
As preferred: the metal raw sheet is reusable, need to be to metal raw sheet after 10~15 reflecting moulds of every production
Carry out disassembly, cleaning.
As preferred: tank liquor used includes nickel sulfamic acid, sodium carbonate, boric acid, nickel chloride when electroforming in the step (3)
And clear water, adjusting pH value is 5.5~6, and in the tank liquor, the nickel sulfamic acid accounts for the 30%-35% of electroplate liquid totality component,
The sodium carbonate accounts for the 5%-10% of electroplate liquid totality component, and the nickel chloride accounts for the 6%-8% of electroplate liquid totality component, described
The concentration of boric acid is 38~45g/L, and the clear water is deionized water.
As preferred: when the loss of nickel stick reaches 50%, supplementing nickel stick.
Beneficial effects of the present invention:
The metal raw sheet of square is rolled into cylindrical metal raw sheet and carries out electroforming by the present invention, can reduce space occupied,
When the reflecting mould of electroforming same size, cylindrical obvious shared space is smaller, economizes the land resource, reduction is produced into
This, and shield gasket processing can reduce the damage of electroforming tank liquor and nickel stick under the premise of meeting the requirements size in raw sheet processing
Consumption reduces waste, and save the cost also facilitates the removing of reflecting mould, and fixes metal raw sheet with insulation board, can play fixation
The effect of metal raw sheet facilitates the cleaning and electroforming of metal raw sheet, and will not impact to the technical process of electroforming.
