The main application field of this product is related to many aspects. From the perspective of "Tiangong Kaiwu", each product has its own specific application.
First, in the field of agriculture, many products provide assistance for agricultural activities. For example, farming equipment plays a key role in planting, cultivation, irrigation and other links. Sophisticated equipment can make farmers work more efficiently and improve the output of the land. As "Tiangong Kaiwu" says, "It is grain, rice. Come, wheat. Mu, barley.
Second, in the field of handicrafts, products are also indispensable. For example, in the textile industry, from cocoon spinning to weaving into cloth, various tools and raw materials are closely coordinated. The book says that "where silk is treated, the first silk cart is made, and its size and equipment are fixed." This shows that products in the handicraft process are effective according to specific regulations to ensure product quality and production efficiency.
Furthermore, the construction field is also an important application. Building materials products, such as bricks and tiles, wood treatment related products, are related to the stability and durability of buildings. "Where mud is used to make tiles, more than two feet of ground is dug, and no sand is selected to stick (pass'clay ') soil." It can be seen that the preparation and application of building materials are crucial in building buildings and other construction activities.
In addition, the military field is also involved. Weapon manufacturing, protective equipment and other related products are related to the victory or defeat of wars and the safety of soldiers. Although "Tiangong Kaiwu" does not detail military technology, the basic materials and processes of war equipment manufacturing are mostly similar to the principles of civilian product production.
All in all, this product plays an important role in agriculture, handicrafts, construction and military fields, just like the key gear in the operation of various industries in ancient times, promoting social production and development.

2%2C5%2C8%2C11%2C14%2C17+-+Hexaoxanonadecan+-+19+-+Ol%2C1+-+Phenyl -%2C4+-+Methylbenzenesulfonate, the Chinese name of this substance may be 2,5,8,11,14,17-hexaoxetadecane-19-alcohol 1-phenyl-4-methylbenzenesulfonate.
Its chemical properties are unique. From the structural point of view, the benzenesulfonate part gives it a certain electrophilicity. The benzene ring is connected to the methylbenzenesulfonate group, so that the substance has certain aromaticity and stability, and the aromatic ring can participate in some electrophilic substitution reactions. The long-chain polyoxyethylene structure (hexaoxetadecanol part) gives it good solubility and surface activity.
Because of its multiple ether-oxygen bonds in the molecule, it has good solubility in organic solvents, especially for polar organic solvents. At the same time, the long chain of polyoxyethylene gives it a certain water solubility, which can form a micelle structure in water, showing the characteristics of surfactants, which can reduce the surface tension of liquids, and may have applications in emulsification, dispersion and other fields.
In addition, the presence of benzenesulfonate ester groups makes the substance capable of nucleophilic substitution reactions under suitable conditions, and hydroxyl groups can participate in esterification, etherification and other reactions, providing a variety of possibilities for its chemical modification and transformation. In the field of organic synthesis, it can be used as an important intermediate to construct more complex organic molecular structures.

The production process of this product is very delicate, just like the techniques described in "Tiangong Kaiwu", which contains the wisdom and ingenuity of the ancients.
The first high-quality materials are obtained, which is the foundation. The selection of materials must be carefully selected, just like panning for gold in the sand, removing the barren and storing the cyanine, so that the raw materials with solid texture and good quality can be obtained. This is the key to the start of the process.
Then, in the workshop, the craftsmen perform their duties and apply exquisite craftsmanship to the materials. Or carving, or forging, the technique is delicate and precise. The carver, holding a knife like a pen, outlines delicate lines on the material, and the lines are smooth and natural, just like heaven; the forger, tempering with fire, makes the material rigid and soft under thousands of tempering. It is particularly important to grasp the heat. If you pass it, the material will be brittle, and if you don't match it, the quality will be soft. You need to be like a famous swordsmith in ancient times. With experience and eyesight, you can control the right heat.
Then, there is the process of coloring and polishing. The coloring needs to choose natural pigments to keep the color pure, long-lasting, and harmless to objects and people. When applying, it is uniform and meticulous, so that the color and material blend and complement each other. Polishing is a test of patience and skill. With sand and gravel of different thicknesses, you can rub it repeatedly, from rough to smooth, until the surface is like a mirror, which can reflect the shadow of objects and feel warm, which is the ultimate polishing.
During this time, the craftsmen follow the method of inheritance, and there is no shortage of innovation and improvement. On the basis of traditional craftsmanship, it is integrated into the aesthetics and needs of the times, so that the products have both ancient charm and today's preferences. This production process is interlinked, and every step is poured into the blood of craftsmen. It is not a day's work. It is the crystallization of wisdom and sweat, creating products of extraordinary quality.

Looking at this product, its market price range is really difficult to determine. Due to the complex market conditions, many factors interact with each other, resulting in unstable price fluctuations.
Today, try to take common sense, if this product has excellent material, exquisite craftsmanship, and scarcity, its price may remain high. Such as rare treasures, with its rare material and exquisite carving, the world is competing for it, and the price is high, or it can reach thousands or even thousands of gold.
If the material is ordinary, the craftsmanship is not special, and it is common in the market, its price should be average. Just like the common cloth and utensils, although they are needed for life, they are not difficult to make and the supply is quite sufficient, and the price may only be a few tens of dollars.
And if this product is born in time and meets the needs of the world, such as medicine during epidemics, armor during times of war and chaos, its price will also change according to the times, or there will be a sudden rise.
Looking at the situation of market competition, if there are many competitors in the same industry, competing with each other for the market, in order to attract customers, or there is a price reduction to increase sales. On the contrary, if a company is dominant and controls supply and demand, the price may be determined at will.
And different regions, the price also varies. In prosperous cities, abundant materials and people, strong spending power, or slightly higher prices; in remote places, there is a difference in supply and demand, or slightly lower prices.
All of these make it difficult to determine the market price range of products, or from counting money to thousands of gold and thousands of gold. It is necessary to carefully observe all the reasons before obtaining the approximate price.

Product Quality Standards are the standards related to product quality, which cover many aspects.
The first is the performance standard, which is the core of the product. Take an appliance as an example, when it has the ability to accurately measure and operate efficiently. Such as a weighing instrument, it must be able to accurately weigh, and the error must be within a very small range to ensure fair transactions; when the device operates smoothly, the speed and efficiency are as expected, so that the performance can meet the standard.
The second is the safety standard, and the product must ensure the safety of the user. For example, the material of the appliance should not contain toxic substances to prevent endangering the human body; the structural design should also be reasonable, without sharp edges and corners causing injury, and have necessary protection, such as leakage protection and overload protection, so as to protect people comprehensively.
Another is the appearance standard, and the appearance of the product cannot be ignored. There should be no obvious flaws, uniform color, and regular shape. If the surface of the appliance is smooth and flat, without scratches or bubbles, it is not only beautiful, but also shows excellent craftsmanship.
There are also reliability standards. The product should be able to function stably within the specified conditions and time. Even if the environment changes or is used frequently, it should not fail easily. If the appliance runs for a long time, the performance is still the same as before, which is the proof of high reliability.
There are other hygiene standards, which are related to human health. Especially food and medical-related products, they must be strictly clean, sterile and non-toxic, and production and storage must follow hygiene standards before they can be used with confidence.
These are the keys to product Quality Standards, and it is difficult to praise them without one. Manufacturers, when they strictly abide by these standards, can produce good products and live up to expectations.
