Product indicators

(1)Yellowish odorless liquid

(2) PH value: acidic products

(3) proportion: >1

Operation method:

(1) The product has A agent and B agent of two components, the volume ratio of A:B=3:5 configured as A working fluid.

(2) the oil removal after silver copper alloy workpiece immersion in polishing working liquid, (40 ℃ - 45 ℃) leaching 8 to 20 seconds, remove the artifacts, clean into clean water immediately.

(3) silver copper chromium-free passivation color retention passivation for 5 minutes.

(4) water washing

(5) drying the workpiece

Matters needing attention:

(1) there will be loss in the use of the product, midway to supplement A and B agent. Generally, agent A is supplemented with 10% of the tank volume, while agent B is supplemented with 5% of the tank volume.

(2) when the tank ion concentration is too high, polishing effect obviously decreased, then to do scrap processing.

(3) waste solution treatment: with stone powder (calcium carbonate) and polishing waste solution, adjust PH=8~9, and then sedimentation, recovery of silver and copper slag, wastewater can be discharged.
