cyclohexane-1,2,3,4,5,6-hexayl hexapyridine-3-carboxylate

The main use of this product is related to many aspects. From the perspective of "Tiangong Kaiwu", all kinds of creations in the world have their own uses.
When it comes to this product, its use is first in the needs of people's livelihood. To cover the daily life of the people, many matters depend on it. As "Tiangong Kaiwu" says, "The silk, hemp, fur and brown in the world have quality", this product may be an indispensable part of people's livelihood, clothing, food, housing and transportation. Taking clothing as an example, if its material is suitable, it can be selected above clothing making, so that the people can withstand the wind and cold, and can show their manners.
Furthermore, it is also useful for craftsmanship. "Tiangong Kaiwu" details all kinds of craftsmanship, and this product may be a key material for craftsmanship. Or because of its tough texture, it can be used for the construction of equipment, making the equipment sturdy and durable; or because of its unique characteristics, it can add a different style to the process, such as in carving, painting and other artistic creations, it can become a good material to show skills.
In agricultural production, it may also be seen. The book also mentions farming-related. This product may be a part of agricultural tools, helping to cultivate and harvest, improving the efficiency of farming, ensuring the harvest of grain, and benefiting the common people.
In the field of commercial trade, its value cannot be underestimated. Because of its wide range of uses, it must be demanded by the market. Merchants from all over the world may trade with each other to promote economic prosperity. Like the ancient Silk Road, many products benefited all parties due to trade circulation, and this product may also be listed, which is an important commodity for trade and promotes economic exchanges and development between regions.
To sum up, this product has important uses in many fields such as people's livelihood, craftsmanship, agriculture, commerce, etc. Just like everything recorded in "Tiangong Kaiwu", each can display its ability and play a key role in the world.

There are many kinds of combined methods for a certain product, each with its own ingenuity. Today's imitation of "Tiangong Kaiwu" is described in Chinese.
Where utensils and objects are combined, the first material is selected. The quality of the material is related to the quality of the finished product. For example, copper and iron cast by smelting, when the refinement is pure and the impurities are gone, the tough material can be obtained. If it is made of wood, choose wood with fine texture and solid texture, such as Nan, sandalwood, etc., which are resistant to corrosion and beautiful.
One of the methods of combining is casting. Take the model as a model and pour the melt into it. Those who cast the bell tripod first use mud to make molds, carve finely, and then fill it with copper liquid. When it cools and forms, knock off the mud, polish it smooth, and then it becomes an artifact. Control of the heat in this process is the key. If the fire is over, the material will be scattered, and if the fire is insufficient, it will be difficult to form.
The second is forging. The iron is heated to red heat, and hit repeatedly with a hammer to make it dense in texture. To make a sword, it must be tempered. At high temperature, the impurities in the iron are discharged with the hammer, and gradually become a sharp edge. And the forging direction and strength are all exquisite, so that the blade body can be rigid and soft.
The third is gluing. This method is often used to connect parts in woodwork. Take natural glue or special adhesive, apply it to the joint, apply pressure to fix it, and wait for the glue to dry and solidify, that is, it will become one. When gluing, the surface must be flat and the amount of glue is moderate, otherwise it will cause degumming or affect the appearance.
The fourth is riveting. Metal utensils are used for many purposes. Use rivets to pass through the parts to reserve holes, and hammer one end of the rivet to make it expand and tighten. This method is firmly connected and can withstand large external forces. For example, in the manufacture of vehicles and ships, many parts are connected by this method.
In addition, there is a method of mortise and tenon, which is the essence of wood. Insert the mortise with the tenon, and the seam is tight, which can be stabilized without nail glue. There are various types of mortise and tenon, such as dovetail tenons, dumpling tenons, etc., which are made according to the structural requirements of the utensils, which are both beautiful and practical, fully demonstrating the wisdom and skills of the craftsman.
All these combined methods rely on the experience and skills of craftsmen, and careful operation can make high-quality products.

Looking at this product, its stability is related to many things, and it is the most important thing. The ancients said: "When you want to do something, you want to govern because of the situation." In terms of products, this "time" and "potential" are also the foundation for stability.
Look at its material first, this is the foundation of stability. If the material is not good, such as using rotten wood as a beam, even if you have clever skills, it will be difficult to support the building without falling. Good materials need to be tough in texture and can withstand the wear and tear of time and the invasion of wind and rain. Like the ancient swords, choose fine iron, and work hard to get a sharp blade. After the cold and heat, the sharpness will not decrease. The materials of the product should also be strictly screened to ensure firmness and durability.
Furthermore, the craftsmanship of the production. "The difference is a thousand miles." Precise craftsmanship makes all parts fit perfectly. The ancient tenon and mortise structure does not need to be riveted one by one, but it can be tightly sewn, and it will not fall after a hundred years. Today's products should also be effective. From the processing of parts to the assembly of the whole, they need to be carefully crafted and cannot allow any mistakes. Every step is made with high standards and strict requirements to create a stable body.
Then, design considerations. Reasonable design can disperse pressure and enhance stability. Just like the cornice bucket arch of ancient architecture, it is both beautiful and practical, and can effectively resolve external forces. Product design needs to be comprehensively weighed, taking into account function and stability. Do not ignore the essence due to the pursuit of novelty, resulting in damage to stability.
Review its use environment. "Orange is orange when it is born in Huainan, and citrus when it is born in Huaibei." The same is true for the product. Different environments have a great impact on its stability. It is necessary to fully consider factors such as temperature, humidity, pressure, etc., and make protection and adjustment in advance. If it is in a hot and humid place, the product is prone to moisture and rust, and special treatment is required to ensure stability.
To sum up, product stability cannot be achieved overnight. It needs to be carefully studied from various aspects such as material, process, design, and environment. Only then can it stand like a rock and be trusted by users for a long time.

In different environments, such as the difference in temperature and humidity, and the difference in acid and alkali, are enough to make the solubility of things different.
If the temperature is high, the molecules of the thing move quickly and are easy to dissolve. Take salt as an example, in hot water, it dissolves after a while, and the particles dissipate and become invisible. Because of the high temperature, the intermolecular force is easily broken, and the salt ions are dispersed in the water. However, in cold water, although it has been soaked for a long time, its dissolution is slow, and even there may be undissolved particles.
As for the degree of wetness, it is also related to dissolution. In a humid place, water vapor pervades, and things are easy to absorb moisture and dissolve. If sugar is in a tidal place and does not wait to enter water, over time, its surface gradually melts, because it is wet and wettable, and its molecules are dispersed. On the contrary, things in dry places retain their shape, and it is difficult to dissolve.
In the environment of acid and alkali, the dissolution of things is deeply affected. The genus of metals is mostly soluble in acids. If iron encounters hydrochloric acid, in an instant, the air will bubble up, and the iron will gradually dissolve. With its strong acid nature, it can react with the metal, causing its molecular structure to change and dissolve. However, in alkali, iron is safe, and there is no obvious dissolution. This acid and base are different, and the dissolution is different.
Looking at all kinds of foreign situations, we can see that the solubility of things changes with the situation. The level of temperature, the dryness of wetness, and the nature of acid and alkali are all the keys. If you want to understand the dissolution of things, you must carefully observe its environment to obtain the true meaning.

Nowadays, there are three kinds of compounds that are better than other similar compounds.
The first is the specificity of their properties. The quality of these substances is completely different from ordinary ones. Other kinds of compounds are either warm and slow in nature, or rigid and easy to fold. However, this object is both rigid and soft, strong in case of strength, and soft in case of weakness. Just like a good sword, a sharp blade can break gold, but the sword body is constantly curved, and its toughness is very high. It can maintain its shape and keep its properties under various environments, and does not move with the environment. This is difficult for other kinds of chemical substances.
The second is a wide range of applications. Other kinds of compounds are often limited in use in a corner. Or it can only be used for the repair of utensils, or it can only help in the production of medicinal stones. However, in agriculture, it can increase the production of fertile fields, so that the five grains are abundant; in work, it can refine fine iron, cast good utensils, and help hundreds of workers; in medicine, it can be used as a good medicine, cure all kinds of evil diseases, and solve the problems of people in the world. From court utensils to folk utensils, they all rely on its power, and its wide use is far better than others.
Furthermore, for the convenience of production. Other kinds of synthetic products, or need rare materials, can not be sought; or need wonderful magic, difficult to manage. The materials used in the preparation of Siwu are mostly common things and can be found everywhere; the methods used are not unfathomable and can be learned by ordinary people. There is no need to go to the deep mountains to seek strange treasures, nor to study immortal techniques to explore mysteries, so that they can be widely used in the world and used by all people.
From this point of view, Siwu is better than other similar compounds in terms of performance, application, and preparation. It is a rare good thing in the world.
