There are roughly six types of gold: 1, [foot gold], [thousands of gold] foot gold and thousands of gold are pure gold. Symbol: AU countries have very clear regulations for each gold jewelry sold by merchants. Yellow It gold jewelry must be listed to indicate its gold content and weight. The gold content is not less than 99 % called foot gold. The gold content is the gold content is not less than 99.9 %. The hardness is not high, so it is generally not set with gems. 2, [Platinum] This has nothing to do with platinum and gold. Platinum is an extremely rare metal, white, hard texture, never fading color, it has a long -lasting value preservation value. Generally Match with diamonds. Also known as Platinum Symbol: PT countries stipulate that only platinum content with 8 5 % or above can be called platinum jewelry and must have a PT logo. rn3、【3D硬金】rn3D硬金或者硬金是指经过工艺改进对纯金在加工过程中进行了改良（通过对电铸液中的黄rn金含量、 The pH value, working temperature, organic optical agent content and stirring speed have been improved, which greatly improves the hardness of gold and abrasion resistance) to make it strong, the finished product is good, it is easy to polish into various shapes, overcome it to overcome The disadvantages of for the lack of pure gold hardness will be more expensive because of the complexity of the processing process. 4, [K gold], [White K gold] [K gold] is a logo for gold jewelry with different gold content. The proportion of 1K gold content is about 4.166 %, and the gold content of 24K, 22K, 20K, and 18K is: 99.99 % (pure gold), 91.65 %, 83.3 2 %, 74.98 %. The rest can be used to get the gold content with 4.166 %. [White K gold] White K gold is not added to gold in gold. 5, [Gold plating] The gold plating is a layer of gold sprayed with other metal surfaces. 6. For hard gold, it can be recycled.

Jin in nature is a natural product that exists in a free state without being artificially synthesized. According to the different sources and the different contents of the content, the content of raw gold and cooked gold. This gold, also known as natural gold, waste gold, and original gold. It is the object of cooked gold. It is a gold that has not been melted and refined from the mining or river base layer. Born gold is divided into two types: mineral gold and sand gold. Mine gold, also known as alleged gold, produced in mines and gold mines. Most of them are hot springs that are pouring underground through the sewing of the rocks. They are often sandwiched in the gap between the rocks. Mine gold is mostly accompanied by other metals. Among them, in addition to gold, there are other metals such as silver, platinum, and zinc. Before other metals were proposed, it was called a precursor. The other metal components produced in different mines are different. Therefore, the percentage is different, generally between 50%-90%. The sand gold is produced at the bottom of the river or a low -lying area, mixed with stone sand, and washed out of the gold. Sand gold originated in the mine, because the gold ore was exposed to the ground. After a long wind and rain, the rocks collapsed through weathering. Deposition is a gold -containing layer to form sand gold. The characteristics of sand gold are: different sizes of particles, large as broad beans, small ones like fine sand, different shapes. The color is different due to the height of the formation. More than 90 % of them are red yellow, eight percent of them are pale yellow, and seven become cyan yellow. Matonous gold is the gold that has been smelted and purified by the gold. Generally, the purity is higher and the density is fine. Some can be directly used in industrial production. Common gold bars, gold blocks, gold ingots, and various jewelry, utensils, gold coins, and industrial gold silk, gold, gold boards, etc. Due to the different uses, the required color is different, or because the device is not purified, it is only melted without purity, or the purity of the mention is insufficient, forming a different golden height. Mathery is used to divide mature golds into three types: pure gold, red gold, and color gold according to the high and low. The gold that reaches a fairly high purity after being purified is called pure gold, which generally refers to gold that reaches more than 99.6%. The meaning of red gold and pure gold is close, but due to the different time and local standards, the standards of Chijin are different. The gold sold in the international market reaches 99.6%. The red gold in the territory is generally between 99.2%-99.6%. It color gold, also known as "secondary gold" and "tide gold", refers to the low color. Due to the different metal content of these gold, the high color is 99%high, and only 30%of the low. The is divided by different metals, cooked gold can be divided into color gold, mixed gold, K gold, etc. The color gold refers to gold only mixed with silver components, regardless of whether it is high or low. There are more color gold, commonly in gold bars, gold ingots, gold blocks and various utensils and gold jewelry. The mixed gold refers to the in addition to the silver in the gold, but also contains other metals such as copper, zinc, lead, and iron. Depending on the type and quantity of the metal contained in, it can be divided into small mixed gold, large mixed gold, bronze mixed gold, and lead -containing large mixed gold. K gold refers to gold and copper according to a certain proportion, and the gold is prepared according to the formula of 24K. Generally speaking, the more the proportion of k gold is silver, the more colorful the color; the large copper ratio is purple. In the early days of liberation of China, my country's K gold was calculated at the standard of each K4.15%. After 1982, it had been unified with international standards, and per K to 4.1666%as the standard.
The maintenance of foot gold, K gold series
gold is a beautiful golden metal with high density, low hardness, high melting point, high boiling point, good ductility and plasticity , Excellent conductivity, heat conduction and other properties. Gold has a high chemical stability, and does not have oxidation effects with oxygen at any temperature, so gold can exist in nature in nature. Gold is insoluble in hydrochloric acid, sulfuric acid, nitric acid and other separate acids. It does not change when it is affected by the action of water, air, acid, alkali, salt and other substances. However, gold is dissolved in Wangshui (HCL: HNO3 1 3: L) and other hybrid acids at normal temperature, and it is also soluble in potassium iodide, potassium cyanide solution and saturated bromine and chlorine water. This and many elements are easy to form alloy, such as lead, nickel, tin, zinc, cricket, copper, silver, platinum, 钯, etc. The color of gold and copper alloy is red, and the color is white when it is silver alloy. When other metal alloys such as nickel, it can form white ... This is why the color of the K gold jewelry is different. Foot gold jewelry is low (Mo's hardness is less than 3). Do not collide with hard objects when wearing foot gold jewelry. If you contact hard objects, you can not only deform the exquisite shape of the jewelry, but also damage the surface of the jewelry, produce deep marks, weaken the reflection strength of the surface of the jewelry, and reduce the golden metallic luster. This not only makes the jewelry lose beauty, but also reduces the value of jewelry. A mercury has a dissolved effect on gold, producing mercury reactions, and forming yellow and white golden mercury. High -level cosmetics often contain a small amount of lead and mercury. Gold jewelry often contacts cosmetics. Over time, white spots will appear on the surface of the jewelry. In this case, the pure gold jewelry will be baked on the fire for a while, and the white spots will be lost. A consumer bought a full golden Tianyuan women's ring at the jewelry counter of a large state -owned shopping mall. One day she found that there was a large obvious white spot on the surface of the ring, so she wondered if the ring was real gold? After finding our testing agency, it is required to identify it. There is no problem after we test the color of the ring. After understanding, she had packed a crushed thermometer, and the ring was accidentally contacted with mercury, so she appeared in golden mercury. Therefore, consumers should not let the jewelry are contaminated by mercury when wearing gold jewelry. K gold jewelry contains a certain amount of silver and copper. The chemical activity of silver and copper is not as stable as gold. They have different degrees of chemical reactions under different conditions such as acid and alkali. Therefore, do not wear jewelry in places with high content such as sulfur dioxide, hydrogen chloride, and hydrogen sulfide, and more severe chemical pollution. Avoid long -term contact with K gold jewelry with acidic, alkaline substances and sweat stains. Points with lead pollution such as printing plants should also avoid wearing gold jewelry. Because aluminum has a capture effect on gold (under high temperature). For a long time, lead particles can also be concentrated on the surface of the golden jewelry. In short, after the golden jewelry is corroded by such chemicals, the surface will change color. In this case, you should use a toothbrush and a small amount of toothpaste to gently brush the K gold jewelry and rinse it with water. Or go to professional manufacturers and merchants polishing and cleaning.
