Abstract
The present invention relates to one kind application environment-friendly type acid fog inhibitor and its application, it is made up of 20% lauryl sodium sulfate, 12.5% bromo pyrrole ingot, 8% alkynol and 6.5% acid amides by mass fraction.Every cube of electrolyte adds 2 6L under 55 65 DEG C of temperature, sulfuric acid concentration 200g/L, the 180A/m2 of current density 150.Suppression acid mist can be taken into account, equipment corrosion is reduced, is improved workshop condition, improves electrodeposition copper mass.
Description
Technical field
The present invention relates to a kind of acid fog inhibitor, specifically a kind of electrolyte with application environment-friendly type acid fog inhibitor and its
Using.
Background technology
Suppressing acid mist in current enterprise mainly has two kinds, and one kind is, by exhaust apparatus, to be absorbed entering after acid mist collecting
Tower treatment, the method investment is big, and high energy consumption, effect is also bad.Second is to add hollow plastic ball to suppress acid in a cell
Mist, but baton round often overflows Lower tank, it is necessary to pull out in electrolytic cell is added in time, baton round is also often attached to cathode copper
On, cause too many trouble to production.Other inhibitor influence electrodeposition copper mass because containing more impurity.
The content of the invention
It is copper suppression acid mist, reduction equipment corrosion, improvement workshop condition, raising electrodeposition to be taken into account the invention provides one kind
The application environment-friendly type acid fog inhibitor of amount and its application.
The technical solution adopted by the present invention is：One kind application environment-friendly type acid fog inhibitor, it is characterised in that：By mass fraction
It is made up of 20% lauryl sodium sulfate, 12.5% bromo pyrrole ingot, 8% alkynol and 6.5% acid amides.
One kind application environment-friendly type acid fog inhibitor application, every cube of electrolyte is in 55-65 DEG C of temperature, sulfuric acid concentration 200g/
L, current density 150-180A/m2Lower addition 2-6L.
The present invention forms the vesicle foam layer of continuous densification, so as to effectively hinder by reducing electrolyte surface tension force in liquid level
The New Type Acid Mist Inhibitor that only sulfuric acid mist is escaped.The fog inhibitor be mainly used in electro deposited copper produce when, Winning cell anode produce
The oxygen effusion a large amount of sulfuric acid of entrainment, form acid mist, heavy corrosion hardware endangers workers ' health.
It is an advantage of the invention that：
1. consumption is few, low cost, and every cube of electrolyte adds solution 200-600ml or so after diluting, and makes after 10 times of dilute with water
With.
2. can be continuously added dropwise in head tank, it is also possible to be injected directly on groove face with sprayer.
3. can be used alone, it is also possible to used simultaneously with other additives, any side reaction will not occur.
4. such as run into crystallization or need to only be heated to melting when being layered.
5. action speed is fast, and effect is good, and 20mm froth beds, the suppression to sulfuric acid mist are formed in liquid level of electrolyzer immediately after addition
Effect processed is up to more than 98%.
Environment-friendly type acid fog inhibitor mainly has the Multiple components such as highly efficient depressor, stabilizer, wetting agent to be composited, composition
There are the organic matters such as lauryl sodium sulfate, pyridine bromide, so impurities phase will not be produced, there is no any shadow to the purity of electro deposited copper
Ring, lauryl sodium sulfate also has the effect of dispersant in addition, during copper is deposited, the phenomenon of reunion is not had, improve
Electro deposited copper surface quality.Alkynol and acid amides have the effect of corrosion inhibiter, the effect that active dose of lauryl sodium sulfate, bromo
Pyrrole ingot has the effect of fog inhibitor.
Specific embodiment
One kind application environment-friendly type acid fog inhibitor, by mass fraction by 20% lauryl sodium sulfate, 12.5% bromo pyrrole ingot,
8% alkynol and 6.5% acid amides are constituted.
One kind application environment-friendly type acid fog inhibitor application, every cube of electrolyte is in 55-65 DEG C of temperature, sulfuric acid concentration 200g/
L, current density 150-180A/m2Lower addition 2-6L.
Claims (2)
- It is 1. a kind of to apply environment-friendly type acid fog inhibitor, it is characterised in that：By mass fraction by 20% lauryl sodium sulfate, 12.5% Bromo pyrrole ingot, 8% alkynol and 6.5% acid amides composition.
- 2. a kind of application environment-friendly type acid fog inhibitor application, every cube of electrolyte 55-65 DEG C of temperature, sulfuric acid concentration 200g/L, 2-6L is added under current density 150-180A/m2.
