Some of our metal relics in many museums are now excavated from the ground. After excavation, many metal cultural relics need to be restored with chlorproline when they are restored, so when they are restored What is the specific method used?
1. We must first protect ourselves when recovering, because the lye itself is a more dangerous chemical substance. If the lye is directly in contact with the chemical when it is used, it may It causes severe damage to the skin and eyes, so special corrosion-resistant rubber gloves are needed to protect the skin when using it.
2. There is also the need to make various preparations before recovery. First, two plastic buckets need to be prepared for use, and a can of flakes of alkali for use, and paper towels are also required. Ready for use, add water to the pot and heat it up, as well as some special cleaning tools.
3. The zinc material used in this process can be recycled.
4. First, mix the solution with boiling water, and slowly put the iron slag into the bucket. Then slowly add the lye to the bucket. When pouring it out, make sure that the lye is not in contact with some other items, etc., and then you can pour boiling water into the bucket.
5. Wait for about 4 hours after soaking in the lye, and then use clean water to clean it. Then wipe it with a paper towel and wipe it until it is completely dry. After that, use a tarpaulin. Soak and wipe away the rust on it. When removing rust, be sure to avoid using some hard metals such as hammers to impact it.
The above is the specific method of recovering metal cultural relics by using lye. Because the substance itself has strong corrosive properties when it is operated again, it must avoid some other impact on itself when it is used.
