Description
Technical field
The present invention relates to field of electroplating, it is specifically related to a kind of plastic parts electro-plating method and plastic parts plating pre-impregnation device.
Background technique
It, before plating, must be in advance in plastic product since plastics are insulators in the plating production process of plastic product
Surface formed one layer of conduct piece (metallic film), for the metallic film as underlying metal, plastic cement products just can be carried out plating, and
The process for forming metallic film is exactly palladium activation.Before carrying out the palladium activation of plastic parts, in order to protect the palladium water in electroplating bath,
Before not allowing in the chrome liquor pollution palladium water remained on the product on hanger and hanger and pretreatment procedure of process hanger and
The moisture dilution palladium liquid taken out of when product on hanger, needs to carry out preimpregnation work in hydrochloric acid to the product on hanger and hanger
Sequence is fallen remaining chrome liquor reduction, and the moisture on hanger and product is neutralized, then carry out palladium activation procedure.
In existing preimpregnation process, usually the product on hanger and hanger is put into pre- immersion trough, is put in pre- immersion trough
The prepreg solution set designs the preimpregnation time using hydrochloric acid as main component, completes after presoaking, then hanger is hung out preimpregnation by overhead traveling crane
Slot moves to palladium slot and carries out palladium activation.During presoaking this, the remaining chrome liquor of product can be restored on hanger and hanger, water
Branch is neutralized, but even across preimpregnation process, in subsequent processing, since palladium (Pd+) is cation, in heavy palladium process
In, palladium ion fails preferably to be attached on hanger and product, and the product on hanger and hanger is still very easy to occur quick-fried
Hook shedding phenomenon (chemical nickel fails to consolidate on hanger gib head completely), causes impurity to pollute subsequent electroplating work procedure, product table
Face easily forms husky point, forms defective products.
