Extended data:

Pure silver is a beautiful silvery white metal with good ductility, electrical conductivity and thermal conductivity. It is the tallest of all metals. Silver is often used to manufacture high-sensitivity physical instrument components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contacts in all these devices are made of silver.

In the process of use, each contact has to work for millions of times, and it must be wear-resistant and reliable, and can withstand strict working requirements. Silver can meet all kinds of requirements. If rare earth elements are added to silver, the performance will be better. The contact life made of silver and rare earth elements can be extended several times.

Silver is a relatively active precious metal, which easily reacts with sulfur or hydrogen sulfide in the air to generate black silver sulfide. This is also the reason why silver jewelry will turn black after use.

Long-term use of silver jewelry has little friction on the surface, and this phenomenon of blackening is more serious after being placed. The material of many silver ornaments is often silver-copper alloy, and this kind of silver ornaments should pay more attention to anticorrosion. In order to prevent silver jewelry from blackening, there are three common methods:

(1) surface treatment: this is an industrial method, which is not easy for individuals to adopt.

(2) Surface coating treatment: coat a transparent clear paint film on the jewelry surface to isolate silver from the outside air. Ordinary wearers can apply colorless and transparent nail polish to jewelry. This method is particularly simple and does not affect the luster of silver jewelry. According to the wearer's specific wearing situation, determine the time interval for applying nail polish or transparent paint film.

Because of the different working environment, people who wear fast can apply it once a week, while those who rarely touch hard objects or wear jewelry for housework can apply it once every half a month or longer. Jewelry that is not used for a long time should also be coated on the surface.

(3) Always keep the silver jewelry clean and dry, try not to let the silver jewelry come into contact with sulfur-containing chemical gases, and do not use sulfur soap to clean the silver jewelry. Silver jewelry should be stored in a sealed and dry place when not in use.

Silver is the only metal that oxidizes when used to make ornaments (commonly known as silver rust), but it is deeply loved by everyone because of its higher reflectivity and brighter color among all metals.

The result of oxidation is yellow or red or black oxide on the surface, and the color varies with the degree of oxidation. Improper use of silver jewelry will greatly accelerate the oxidation speed, so before deciding to buy silver jewelry, you must know the correct wearing method.

1, it is best not to wear it when taking a shower or sleeping.

2, avoid contact with flowing air when not wearing, should be put in a jewelry box or sealed bag.

Don't swim with you, especially in the sea.

People who sweat a lot are not suitable for wearing silver ornaments.

Treatment of silver ornaments after oxidation;

1. Wipe the surface with a silver cloth. If the oxidation is serious, it can only be wiped off by force. Then use detergent to clean the black oxide on the surface and dry it with a paper towel.

2. Silver washing water: Because silver washing water will corrode the surface of silver ornaments, it can only be used in the case of serious oxidation of silver ornaments and cannot be used repeatedly. Immerse the silver ornaments in silver washing water for 5 seconds, and then wash the surface with detergent. Don't let the silver washing water remain on the surface, dry it with a paper towel.

Service life of silver jewelry: If you wear silver jewelry correctly, you can use it for about 3 months to 6 months.

Despite the above maintenance measures, if the silver jewelry is still black, the following methods can usually be taken to restore the original luster of the silver jewelry.

(1) polishing method: This method is better for plain silver head injuries, such as flowerless bracelets and collars. When polishing, you can use silk or toothbrush dipped in a small amount of toothpaste to polish it repeatedly at the place to be polished until the surface of the jewelry is as clean as new, and then wash it with water after polishing. However, this method is not very effective for ordinary carved or carved silver ornaments.

(2) Put some pieces of broken aluminum under the silver ornaments, then put them into soda solution and heat them together to remove the black. Because soda is very alkaline and heated, this method cannot be used for silver jewelry with jewelry.

(3) After cleaning with 1% hot fat room solution, soak the silver ornaments with sodium thiosulfate solution (photographic fixing solution, also called Haibo), and then wipe them with toothbrush or fiber cloth.

(4) If the black on the jewelry is heavy, it can also be washed with concentrated hydrochloric acid. After washing, it should be washed with clear water immediately. Jewelry inlaid with pearls, malachite and turquoise must not be washed with hydrochloric acid, otherwise it will damage the jewelry.
