Before cleaning, there are four oxygen-free copper blocks provided by the customer. The customer requests to soak COP01 after soaking the copper blocks No. 1 and 2. For copper blocks No. 3 and 4, the customer requires that only COP01 be soaked.

in room temperature. Soak with 10% copper oxide reducing agent COR01.
COR01 is a reduction method to reduce copper oxide to copper, and has the effect of surface agglomeration, which can protect the copper alloy from oxidation.

It may be that the oxygen-free copper block provided by the customer is slightly oxidized. After soaking for 2 minutes, it is found that the darker spots on the original copper block have disappeared.
Number 1 is on the left and number 2 is on the right.

After soaking for 5 minutes, take it out and rinse it with clean water. No. 1, 2 and No. 3, 4 oxygen-free copper blocks are placed in 10% COP01 copper protective agent at room temperature. Soak for 10 minutes.

take out. No more flushing, just air dry. Compare:
Process with COR01+COP01:

After soaking COP01, there is no significant difference in surface color and gloss.
The actual test, standing at room temperature, found that after 6 months of storage, it can also effectively prevent the copper block from continuing to oxidize and blacken.
