Supply copper cleaning agent and brass brightene

Statement: the copper content is less than 59%, and the cleaning effect is relatively poor
This product is used in pure brass, pure red copper, pure red copper and other pure copper parts; If you need to clean electroplated copper, the soaking time should not be too long
Those with less serious oxidation can be cleaned
If the oxidation is serious or the coating has fallen off, the cleaning effect is relatively poor
Customers with high requirements are not recommended to buy this product
Those with antique technology on copper doors cannot use this product! For example, when cleaning copper coins, due to the different year content of copper coins, it is impossible to ensure that the cleaning effect of each kind of copper coins is good
It is recommended to test in a small area before normal cleaning
Do not use machine polishing!
1、 Product features:
916 is suitable for polishing brass, red copper, red copper and other copper materials
After oxidation or discoloration, the copper parts can appear specular luster after treatment, but there is no unpleasant smell produced by three acid polishing, no bubbles and no heating
The whole polishing process is smokeless and tasteless, the stock solution is easy to operate, the working fluid does not hurt hands, and the salt spray resistance time can be greatly strengthened after passivation, Long anti-oxidation time
The clean activated layer produced after polishing of copper parts prepares the required surface for subsequent processes such as electroplating, oxidation, passivation, welding and painting

2、 Process flow:
Degreasing of copper parts → Water washing → Polishing (30 to 60 seconds) → Water washing → Passivation & rarr; Water washing → It is recommended to soak in 80 ℃ hot water for 10 seconds → Drying → Finished product packaging
3、 Operating conditions:
Name Name: Use amount
916: use of stock solution
Temperature: room temperature
Time: 30-60 seconds
Mixing: standing or mixing
Precautions: the polishing time is uncertain until the effect is satisfactory, but it should be noted that too long polishing time will damage the workpiece, so the time should be in order to ensure that the workpiece is not damaged
The drying temperature cannot be higher than 100 ℃
4、 Solution maintenance and precautions:
1
After polishing, the copper parts must be cleaned with flowing water as soon as possible

2
In order to prevent the copper parts from oxidation and discoloration in the air after polishing, it is recommended to use 75501 copper passivator of our company
If the polishing effect is not ideal, the polishing can be repeated

3
If the polishing efficiency decreases, it is necessary to replace the polishing solution
