Description
Technical field
Electrolysis field is the utility model is related to, more particularly to a kind of electrode coating prosthetic device.
Background technology
Ion-exchange membrane electrolyzer is since last century the seventies are gone into operation applied to chlorine industry, 40 years so far,
Application of ion-exchange membrane electrolyzer metal anode and manufacturing technology have obtained development at full speed during this.However, existing ionic membrane electricity
Solution groove metal anode is influenceed by life of product and running environment, after operation electrolysis is participated in, still occurs that anode is damaged, applies
Layer activity decay so that cause the tank voltage of electrolytic cell raise, electrolysis energy consumption increase, electrolytic efficiency decline, product purity reduction
The defects of.
Wherein, have the reason for metal anode coating activity decay a lot, for example long-term electrolysis makes in metal anode coating
Reverse current impacts when active component is washed away by gas in electrochemical reaction corrosion and passivation, course of reaction, stops electrolysis
Ultimately result in disbonding Deng can all consume metal anode coating, come off, the lost of life, activity decay；And participate in its of electrolysis
His material can then reduce the active site of metal anode active coating participation reaction in its surface deposition, cause metal anode coating to lose
Deactivation, electrolytic efficiency reduce, current potential raises, energy consumption increase.In addition, other occurred in running environment and service condition are anon-normal
Chang Yinsu may also cause metal anode breakdown or abrasion is failed so as to influence metal anode coating.
Due to the metal anode for ion-exchange membrane electrolyzer more using the metals resources such as expensive titanium as base material, into
This is higher.It is after anode electrolysis performance reduces to consider to repair it to reduce the wasting of resources, reducing cost more, make again
With.And the reparation of metal anode can save substantial amounts of resource and coating expense, after the metal anode after reparation comes into operation
Considerable economic benefit can be brought.
At present, the method for anode reparation can be divided into remove original coating with it is non-remove original coating both.Past by
The influence of coating manufacturing technology, production quality and running environment, the extent of damage after anode electrolysis is higher, is typically chosen original
The mode for having coating to remove completely is repaired to metal anode.Wherein, the method for going removing coating to repair metal anode
Mainly using fused salt, hydrochloric acid boils, sulfuric acid boils, sulphuric acid electrolyte the methods of original coating is completely peeled off, make base material again
It is exposed, it is coated after then exposed base material is handled again, produces the gold that new coating has been applied in up to standard the draping over one's shoulders of properties
Belong to anode.This method can obtain relatively good metal anode repairing effect, but it is former cated to need strict selection to remove
Process conditions, the rate of corrosion to expensive metal base is controlled, while also to consume the chemical materials such as substantial amounts of acid, salt, its
Rehabilitation cost is higher, and has certain harm to environment and operator.Original coating reparation metal anode is removed according to non-,
Although easy to operate, because the original coating each several part level of deactivation of metal anode is inconsistent, coating binding force is uneven after reparation
It is even, performance is unbalanced, cause that electrocatalysis characteristic is poor, the life-span is shorter after metal anode is repaired.
With the continuous development of technology, the coating quality for the ion-exchange membrane electrolyzer metal anode coating applied in the market
Very well, the residual quantity of the coating after metal anode electrolysis performance reduces is larger, and the uniformity is also relatively preferable.Using non-removal
Original coating, which carries out reparation to ion-exchange membrane electrolyzer metal anode, can make full use of resource, and reduction goes to make base material during removing coating
Into loss, while the original coating in part can also be utilized, reduce cost of material.It is also, non-to remove original coating reparation metal sun
The technique of pole is relatively easy, reduces the consumption of the resources such as other chemical raw materials and water power, is also beneficial to environmental protection and protection is grasped
The safety of author.
