Our company teach your crystallizer copperplate to eletroplate the knowledge of iron craft

Crystallizer copperplate eletroplates iron craft
Manufacturer of storage rackSweet clew: One, characteristic
1, solution is stable, operation temperature is wide.
2, deposition rate is rapid, film is crystal and meticulous shining, without hole.
3, it is good that film adds exert oneself, but plating deep film. Ply amounts to 1-3mm
4, cost is low, the operation is handy.
5, film is able to bear or endure corrode sex is tall, service life is long.
2, crystallizer copperplate eletroplates iron craft
Composition limits standard
Ferrous 450~650 captures amino sulphur sick at heart / rise 600 grams / litre
Additive of Dw-010 plating iron (agent opening a crock) 30 milliliter / rise 30 milliliter / litre
Milliliter of 0~8 of Dw-012 wetting agent / litre inspect need
PH 1~3 1
58 ℃ of temperature 50~60 ℃
Current density 1~20 ampere / decimetre 2 3 ampere / decimetre 2
Positive pole pure iron or mild steel (carbolic content is less than 0.1% , lap with zincous bag)
Filter circularly or filter regularly, cathode rotates 5~12 turns / minute.
3, fill add
Additive of Dw-o10 electroform iron (replenishers) 100~150ml/ 1000 how. Hour
Dw-012 wetting agent inspects need to add, unfavorable excessive.
4, plating fluid is made up
New does the plating iron solution that make up want to accumulate: in zincous face? ? of Qiong  Biao, 8~10A/dm2 of cathode electric current, temperature 50~60 ℃ , PH1, electrify processing comes solution Qing Dynasty is green. PH on the low side, cannot adjust with alkaline, ammonia, can electroanalysis only rise, if can be produced, straightforward production. Plating qualification trying plating, add additive, normal production.
Positive pole uses bag of positive pole of make it of polyester fibber cloth to cover, the groovy juice that just had mixed should increase iron ion concentration, when groovy edge iron plate hangs some of; to produce more as far as possible, zincous area / cathode area 2.5, when plating chamfer out of service, positive pole is not taken out, maintain PH1.
Plating chamfer safeguards: Want to clean zincous, zincous bag regularly, filter regularly. If grease pollutes plating fluid, add activated carbon adsorption to filter if; has metallic impurity pollution, use ripple board to electroanalysis.
Other drug is not added please in plating fluid, solution part has been jumped over simplier, lest create film in organic matter be mingled with, cause film to rise fragile, hydric adsorption causes pinhole. Want to maintain the stability of PH, lest worsen film.
5, technological process:
Hang on workpiece clean pickling except oil (use 10% hydrochloric acid to clean plating iron examine crystallizer copperplate eletroplates pickling can use phosphoric acid, also can use electroanalysis pickling
6, breakdown processing
Solution of normal iron of amino sulphur acerbity plating is Danqing green, if appear tender yellow, explain solution is abnormal, should move PH to be less than 1, join 5~10 milliliter / Dw-010 of additive of iron rising report and agitate of reductive iron pink, wait for the production after its color is normal. Layer of normal plating iron should is Hei Liang, smooth, if exterior grain is coarse, explain solution is dirty, need filters, slant like film black, explain solution is polluted by organic matter, be like citric acid, should join 2~3 to overcome / rise adsorption of farinaceous activated carbon to filter, tone PH is less than 1, electroanalysis to film normal. If film surface submits bark form coarse, handle way: Should move PH to be less than 1, join 5~10 milliliter / additive of iron rising report and agitate of reductive iron pink
