Description
(1) technical field
The present invention relates to a kind of electroplating process, particularly relate to the processing method of the hard chromium of a kind of Novel electroplating.
(2) background technology
Traditional electroplating technology is by pre-treatment → plating → passivation → drying → packaging, performance and appearance requirement to product are all not high, and the development along with national economy, the requirement of product surface quality is improved constantly by people, and then drive the development of process for treating surface, electroplate as the application of the most general process for treating surface also more and more extensive. The pollution substance that the consequent is disposed in environment is paid attention to people by national. Traditional wastewater treatment process is the combination of the final program element such as process of a series of physics, chemistry, biology and mud, and so its treating processes redundant and complicated, cost remains high, and operationally often has many restrictions. My company fully responds the call of country's cleaner production, processes decontamination from source of pollution, reaches cleaner production truly.
(3) summary of the invention
It is an object of the invention to design the processing method of the hard chromium of a kind of Novel electroplating. Achieve the cleaner production of chrome-plated process, use is all reclaimed in all washings in technique, especially washing water treatment after plating, it adopts multistage overflow automatic spray method, the steam output of water spray and plating tank water is allowed to keep balance, both achieve the zero release of water, achieve again the recycling of chromium.
The technical scheme of the present invention: the processing method of the hard chromium of a kind of Novel electroplating. It is characterized in that whole technique by pre-treatment, antipole, electroplate and drain and form, wherein pre-treatment comprises electrolytic degreasing, 3 road washings, activation and the washing of 2 roads, wherein utilize acid-base neutralisation principle by 2 roads acidity washing water after activation by 3 roads alkalescence washing water after blowback electrolytic degreasing, more unnecessary waste water is extracted into coarse filter by pump, after adsorption tower, accurate filter and exchange resin tower, returns to the washing of the twice after activation again. Achieve the wastewater zero discharge of pre-treatment. Washing in the plating process adopts multistage overflow automatic spray method, by water being added to during spray washing product the washing tank minimum containing chromium concn, again the washing fountain solution the highest containing chromium concn is added to plating tank, and the steam output keeping water spray and plating tank liquid balances, the realization washing water zero discharge of continuity and waste liqouor utilize.
Multistage overflow automatic spray method as above, multistage overflow automatic spray comprises 5 road washings, it is followed successively by washing one, washing two, washing three, washing four and washing five, its water contains chromium concn by high to Low, from plating tank away from washing five minimum close to pure water containing chromium concn, the pure water of pure water tank is supplemented by pump and washes in five grooves by being added to by water during spray washing product, successively utilize pump be extracted into washing five grooves in Water spray supplement washing four, washing three is supplemented with reason, washing two is being supplemented by washing three overflow port overflows, washing one is supplemented with reason, plating tank will be added to again containing chromium concn the highest washing one liquid.And the steam output keeping water spray and plating tank liquid balances, the realization washing water zero discharge of continuity and waste liqouor utilize.
The superiority of the present invention: the cleaner production achieving chrome-plated process, use is all reclaimed in all washings in technique, especially washing water treatment after plating, it adopts multistage overflow automatic spray method, the steam output of water spray and plating tank water is allowed to keep balance, both achieve the zero release of water, achieve again the recycling of chromium. Without the need to extras and resource, save old, it is to increase economic benefit, truly achieve cleaner production.
