CHLOROPYRAZINE, 2-(SG)

The main use of mercury in ingots and subtracts (SG) is particularly important. Mercury in ingots and subtracts (SG) are described in Tiangong Kaiwu, and each has its own use.
Mercury, that is, mercury, is mobile and heavy in quality. It can be obtained by firing in pill sand. It has a wide range of uses. In ancient times, it was often used by alchemists to refine the medicine of longevity. Although the practice of seeking longevity has not been fully successful, the characteristics of mercury have been explored in the process of alchemy. And mercury has also been used in medicine. For example, in ancient recipes, mercury was occasionally used as medicine to treat diseases with its special medicinal properties. In addition, mercury also plays a role in metal smelting, which can form amalgam with other metals to help separate and purify metals.
As for the two subtractive (SG), although the exact meaning of "Tiangong Kaiwu" has not been studied in detail, it is speculated that it may be a certain type of chemical raw material or mineral product. In ancient technology, or for ceramic firing, it can help adjust the glaze color and improve the texture; or in metal casting, it has the effect of refining and modification; it may also be used in the preparation of dyes and pigments, which affects the color and fastness.
Ancient craftsmanship, used in various types of substances delicately, although mercury and two subtractive (SG) are not as well known as rice, wheat, and millet, but in specific fields, they are indispensable materials and contribute a lot to the development of technology and life at that time.

Mercury, also known as "mercury (SG) ", has unique physical properties and is of great research value. Mercury is in a liquid state at room temperature and pressure, which is one of its remarkable characteristics. Unlike many common gold that is solid at room temperature, mercury is like flowing silver, shining with a unique metallic luster, which is agile and wonderful.
Its density is quite high, about 13.6 grams/cubic centimeter, which makes mercury particularly heavy in liquids. Placing mercury in a container can clearly detect its heaviness. At the same time, mercury has good electrical conductivity. Although it is not as excellent as silver and copper, it also has unique uses in the field of electricity, and can act as a conductive medium in specific circuits.
Furthermore, the melting point of mercury is extremely low, only -38.87 ° C, which means that mercury can still maintain a liquid state in an ordinary low temperature environment. And its boiling point is 356.6 ° C. When the temperature rises to the boiling point, mercury will melt into a gaseous state and escape into the air.
Mercury has a high surface tension. On a clean plane, mercury droplets will gather into a nearly perfect spherical shape, resembling round water silver beads, rolling freely, which is very interesting. In addition, mercury also has a certain degree of volatility, which will slowly evaporate into mercury vapor at room temperature. This characteristic requires special attention. Because the vapor is toxic, if accidentally inhaled, it will cause serious damage to human health.

Mercury (Hg), also known as water, is one of its compounds, mercury dichloride (HgCl ²), which is commonly used as mercury, and has a certain degree of chemical properties in the period of "Tiangong".
Mercury dichloride, white as snow, is poisonous, and is known to the ancients as a toxic substance. As described in "Tiangong", it can be poisoned by humans. In ancient times or in life, it was occasionally used to treat some pests, which was based on the lethal effect of its toxic pests.
In addition, mercury dichloride is easily decomposed. The ancients in the process of chemical extraction or inspection of some things, there was a phenomenon of its addition, and there was a phenomenon of material transformation. For example, in the early Dan Dynasty, the addition of mercury dichloride can remove its original solid white material, and produce raw materials or other forms of materials due to decomposition. This image reflects its uncertainty.
In addition, mercury dichloride has a certain solubility in water. Under limited conditions, people also realize that when it is put into water, it dissolves gradually and disappears, and its aqueous solution is toxic. This property is exploited in some ancient applications or special applications. For example, the configuration of some external applications, using its dissolution properties, is used in the form of an aqueous solution for treatment, etc., but due to strong toxicity, it is used with caution.
In the last generation of "Tiangong Wuwu", people have initially grasped the importance of mercury dichloride, which has been applied in many aspects such as life, engineering, and engineering.

Mercury is a highly toxic substance, and there are many taboos to reduce (SG) in production, which should be explained in detail.
First of all, it is related to protection. Mercury is volatile and enters the air, which is an invisible harm. Therefore, in the place of production, it must be well ventilated to drive away mercury gas and not allow it to accumulate. When craftsmen work, they must also wear protective gear, such as masks and gloves, to prevent mercury gas from entering the body and hurting their internal organs.
Second, the rules of operation. Be careful when taking and transferring mercury. Do not spill mercury on the ground. If it spills, cover it with sulfur quickly, and turn mercury into mercury sulfide to reduce its toxicity. And when it comes to the measurement and mixing of mercury, it must follow the rules, and do not do it at will, causing accidents.
Furthermore, pay attention to the inspection of equipment. Equipment used in production must be inspected frequently to prevent it from being damaged and mercury leaking. If the equipment is damaged, it should be repaired quickly. Before it is repaired, it should not be used lightly to avoid the spread of mercury.
Also, it is related to the principle of waste. Mercury waste cannot be discarded at will, and must be disposed of in accordance with regulations. Or send it to a special place, perform recycling methods, or go through specific techniques to turn harm into profit. It must not be discarded in the wild, ditches, causing sewage and soil, harming all living beings.
All these things are important in mercury reduction (SG) production. If you follow them, you can ensure safe production and avoid mercury damage; if you disobey them, you will have disasters and endanger everyone. Craftsmen should keep it in mind and dare not slack a little.

"Tiangong Kaiwu" says: "Silk, hemp, furs, and browns in the world all have qualities, which make it possible to be different in appearance. I don't believe it if it is said that the creation of things is not laborious." Although the market price range of halogen to be crooked (2 - (SG)) is not directly stated, it can be deduced from the common sense of things.
The price of goods in a merchant often depends on supply and demand, cost, and materials. If halogen to be crooked (2 - (SG)) is a rare thing, and there are many people who ask for it, its price will be high; if the product is very easy and the supply exceeds the demand, the price will be flat. < Br >
And if it requires rare and expensive materials, or goes through difficult processes, the cost is high, and the price is not low. On the contrary, if the material is easy to obtain and the production is simple, the price will also drop.
The ancient city was easy, but the price was not static, and it varied from time to time and place. In the year of abundance, the price may be slightly reduced; in the age of famine, the price will rise. In Dayi, the capital, merchants converge, and the competition is fierce, and the price may stabilize; in remote places, the circulation of goods is not smooth, and the price may be high.
Therefore, if we want to determine the market price range of halogen (2- (SG)), we must carefully consider its supply and demand status, production cost, time and place, etc., and comprehensively weigh it to obtain a more accurate number. However, only a few words are based on this, and it is difficult to determine its detailed price range.
