Service life is to be improved, and is being used for a long time, and after coating result is deteriorated, the recoverable rate of anode plate is low.
Summary of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, provides that a kind of good conductivity, coating activity is high, the service life is long, and recycles
The high anode plate with noble coatings of utilization rate, including titanium-base, are successively enclosed with tantalum coating on titanium-base and platinum applies
Layer, the tantalum coating includes the tantalum liquid of eight layers of sintering, after tantalum liquid coats each time, first 10-30min dry at 100-150 DEG C,
It then at 480-530 DEG C of sintering 30-50min, and is cooled to room temperature, is repeated eight times altogether；
Platinum coating includes the platinum liquid of six layers of sintering, after platinum liquid coat each time, elder generation in 100-150 DEG C of dry 10-30min,
Then at 500-530 DEG C of sintering 10min, cooled to room temperature, repeatedly six times altogether.
The present invention has the anode plate of noble coatings, and the tantalum liquid comprises the following components in parts by weight:
The present invention has the anode plate of noble coatings, and the platinum liquid comprises the following components in parts by weight:
30-40 parts of chloroplatinic acid

Then at 500-530 DEG C of sintering 10min, cooled to room temperature, repeatedly six times altogether.The platinum liquid includes the group of following parts by weight
Point: 30-40 parts of chloroplatinic acid, 60-70 parts of 10-15 parts of hydrochloric acid, the propyl alcohol that concentration is 3-4mol/L.
The present invention not only good conductivity, coating activity is high, uniformity is good, the service life is long, and be used for a long time, coating result
After variation, the also recyclable recoating platinum liquid of anode plate greatly reduces cost.
It is above-mentioned according to the present invention for enlightenment, through the above description, relevant staff completely can without departing from
In the range of this invention technical idea, various changes and amendments are carried out.The technical scope of this invention is not limited to
In the content on specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
