1、There is platinum plating on the Platinum plating anode, the main role is to prevent the titanium anode passivation caused by direct contact with chromium liquid. Platinum plating is very easy to friction on a hard object or from time to time be scratched or damaged on the surface, so measures should be taken to prevent the anode in a work by mechanical damage. For example, it is forbidden to make the platinum plating surface placed directly on the metal surface or in any hard surface drag or sliding; Avoid using a wire brush, copper wire brush, sharp tools or article such as sandpaper friction platinum anode surface plating platinum plating layer and damage.

2、In order to avoid pollution, oil pollution platinum plating，the platinum plating anode operators must wear clean gloves, when installing. Grease pollutants can be in contaminated parts to prevent the happening of the electrolytic. The part without pollution will be under the higher current density and become very active. As a result, the anode current distribution uneven and lead to the platinum plating to wear and tear unevenly.

3、Platinum plating anode is fixed on the titanium or titanium frame through the titanium screws, then connected to the conductive copper plate. The user should check all the contact points now and again in the work, in case of the screw loosening or conductive copper platoon is etched or fracture. All these bad contacts will lead to the conductive adverse, which cause the local fever, burning or lighter made the platinum plating anode passivation.

4、The distance equal as far as possible between positive electrode and negative electrode when electroplating. The distance should be in above of 80mm.If the distance is unequal between positive electrode and negative electrode, it will lead to the positive anode current density is inconsistent. In the process of actual use, the closer near the negative anode, the faster aging.

5、When electroplating the larger parts, the user should check that whether the area of the positive anode is 1.5- 2 doubles to negative anode area. If the negative anode area and positive anode area is less than 1:1. 5 doubles, the user should reduce electric current density, and extend the time of chromium plating properly. Otherwise too high current density will accelerate anodic aging. (Anode current density not more than 40 a/square decimeter)

6、Chromium plating solution in principle does not allow any solid particles with solution cycle, which causes the platinum plating to wear and shorten the service life of plating platinum anode. If there are solid deposits attached to the platinum anode surface in plating solution, it will result in anode current distribution unevenly. Such as chromium plating solution of lead chromate, barium sulfate, etc.

7、On a quarterly for the unit, it is necessary to remove and clean the platinum plating anode, replace the unusable titanium screws, check all the conductive contacts. To make sure that all the contact point contact is good. At the same time, clean the lead chromate in the lining adhered to the positive anode thoroughly, ensure lead anode in good condition.

8、To clean the plating platinum anode, the user should pay attention to the notes and do as follows:

① Make the platinum plating anode soaked in 5% of dilute sodium hydroxide solution, using soft cloth or sponge to wipe auxiliary reaction, so that to remove surface chromate;

② Then use the use 5% of dilute sulphuric acid solution to neutralize the residual sodium hydroxide solution on the anode surface

③ Finally, with plenty of clean water rinse anode. It is prohibited to use any abrasive or mechanical removal of platinum plating anode surface sediment.

9、 If the plating platinum anode without using for a period of time, you should immediately remove it and clean. it is very important. If you do not clean the anode, the platinum plating will be affected by sulfuric acid corrosion and cause irreparable damage. The reason is that the plating solution in the platinum plating surface gradually become dry, and cause acid concentration increases, the corrosion of titanium anode surface and matrix.

Special note: Titanium plating platinum anode substrate for pure titanium, titanium is easily react with fluoride ions, so carefully with fluorine ion in chromium plating liquid into. When using chrome plating additive or chromium fog inhibitor also should check for fluoride additives, otherwise it will lead to the titanium substrate by corrosion, surface platinum plating layer falls off, shorten the service life of plating platinum anode.
