Abstract
The scavenger consists of strong base, sodium salt of strong acid, dodecyl sodium sulfate, disodium complexonate and water. During compounding the scavenger, the strong base and the sodium salt are first dissolved in water, and the dodecyl sodium sulfate and disodium complexonate are then added into the solution. The scavenger has excellent scavenging effect and no corrosion to lead-tin anode.
Description
The present invention relates to a kind of clean-out system that is used for the chrome-plated process lead-tin anode, belong to the electroplating technology field.
In chrome-plated process, generally adopt terne metal as anode, after the certain period was carried out in plating, the terne metal anode surface can adhere to one deck dirt, and this layer dirt mainly is lead chromate and lead sulfate.Lead chromate and lead sulfate are water insoluble, but attached on the terne metal rod, if untimely removing can influence the electric conductivity and the electroplating efficiency of electrode.Traditional removing way is a mechanical grinding, promptly with water cleaning again behind the sand paper removal dirt.This method method both wasted time and energy, and influenced the anodic size again.Once the someone adopted based on sodium hydroxide, suitably added the clean-out system that yellow soda ash is made, though this clean-out system has certain cleaning performance, its cleaning performance is not ideal enough, and antianode has certain corrosive nature.
The objective of the invention is to propose a kind of lead-tin anode clean-out system that is used for chrome-plated process, adopting very strong alkali of cleanup action and chromium cooperation is the main clean-out system of forming with stronger organic acid salt, a spot of tensio-active agent and inhibiter have been added simultaneously, with the infiltration situation of improving the clean-out system antianode with further prevent the anodic corrosion.
The lead-tin anode clean-out system that is used for chrome-plated process that the present invention proposes, this clean-out system is made up of the composition of following weight percent:
Highly basic 5~15%
Strong acid sodium salt 5~10%
Sodium lauryl sulphate 0~0.6%
Disodium EDTA 0~0.6%
All the other are water
Above-mentioned highly basic and strong acid sodium salt is even with water dissolution in proportion, add sodium dodecyl and disodium EDTA again, stir, be clean-out system of the present invention.
This clean-out system has better cleaning effect, and in cleaning process lead-tin anode is not had corrosive nature.In order to have good cleaning performance and low corrodibility simultaneously, utilize this clean-out system cleaning terne metal anodic way to be, the terne metal anode is immersed in the clean-out system tens of minutes, dirt on the lead-tin anode i.e. dissolving voluntarily, with cloth wiping anode gently, the water flushing gets final product again, uses very convenient.
Clean-out system main component of the present invention is a highly basic, and as NaOH and KOH, content is 5~15%, and cleanup action is poor very little, and too many corrodibility is strong, makes operation and disposes waste liquid and all add to the difficulties.Auxiliary clean-out system is the strong acid sodium salt, they can be yellow soda ash, sodium oxalate, sodium tartrate, Trisodium Citrate, Sunmorl N 60S etc., content is 5~10%, can in addition also be added with tensio-active agent, as sodium lauryl sulphate and inhibiter with wherein one or more are used, disodium EDTA content is below 1%, and all the other are water.The sodium salt of highly basic and strong acid is even with water dissolution in proportion, add tensio-active agent and inhibiter again, stir, promptly get clean-out system.
Be clean-out system preparation embodiment below.
Embodiment one
Sodium hydroxide 7
Trisodium Citrate 10
Yellow soda ash 8
Sodium dodecyl 0.5
Disodium EDTA 0.5
Water (deionized water) 74
Embodiment two:
Potassium hydroxide 10
Trisodium Citrate 5
Yellow soda ash 5
Sunmorl N 60S 5
Disodium EDTA 0.5
Water (deionized water) 74.5
Embodiment three:
Sodium hydroxide 13
Sodium tartrate 6
Yellow soda ash 4
Sunmorl N 60S 5
Disodium EDTA 0.5
Water (deionized water) 71.5
Embodiment four:
Sodium hydroxide 10
Yellow soda ash 5
Sunmorl N 60S 5
Sodium dodecyl 0.5
Water (deionized water) 74.5
Weigh up according to the required amount of medicament of above-mentioned prescription, after deionized water dissolving, add tensio-active agent (SDS) and inhibiter (disodium EDTA) again, stir and to use, will desire cleaning electrode and immerse in the clean-out system tens of minutes, take out the back and clean electrode gently with cloth, water flushing then, electrode can restore to the original state, when electrode soaks, if can add sonic oscillation, better effects if.
Claims (3)
