What is the chemical structure of this product?
The chemical structure of this product is an exquisite construction of the microscopic world, which is related to its essential characteristics and functions. The concept is like an exquisite labyrinth, where every connection and every atomic arrangement have profound meaning.
It is like all kinds of creations described in "Tiangong Kaiwu", each formed according to its own reason. The chemical structure of this product also follows the laws of nature and chemistry, and is bonded and arranged by atoms and molecules in a specific way. Its atoms are connected by chemical bonds, or covalent bonds, which share electrons with each other and are closely interdependent, just like the tenons and mortise carefully spliced by craftsmen, which are stable and tough; or ionic bonds, where anions and cations attract each other to form an orderly lattice, such as the bricks and stones of ancient city walls, which are regular and solid. The spatial configuration of the
molecule is also crucial. Either it is a straight line, with atoms extending along a line, which is concise and orderly; or it is a tetrahedron, with the central atom as the core, and the surrounding atoms are distributed at a specific angle to build a stable three-dimensional structure. This spatial layout affects the forces between molecules, such as van der Waals forces, hydrogen bonds, etc. The existence of hydrogen bonds makes the molecules seem like a pair of invisible hands that pull each other together, which has a profound impact on the melting point, boiling point, solubility and other properties of the product, just like a wedge between mortise and tenon, enhancing the stability of the whole.
This chemical structure is not static, and external conditions such as temperature, pressure, pH, etc. can cause subtle or significant changes. The temperature increases, the molecular thermal motion intensifies, the vibration of chemical bonds is enhanced, or the structure is loosened; the pH changes, and the degree of ionization is different, which affects the ionic bonds and molecular charge distribution, and then remodels the structure.
The chemical structure of this product is a complex and delicate system. The interaction and mutual restriction of various elements jointly determine the unique properties and functions of the product, and also lay the foundation for its application in different fields, just like the creation in "Tiangong Kaiwu" plays a unique role according to its delicate structure.
What are the main uses of the product?
The main uses of products are related to people's livelihood, and so on.
In the realm of daily use, many products are necessary for people's daily living. For example, woven cloth and silk can be used to tailor clothes for everyone, shelter the body from the cold, and can enhance people's demeanor. There are also fired pottery and porcelain, which can be used as eating utensils, which can hold water, which are sturdy and durable, making eating more convenient.
In the field of labor production, products also play a key role. Such as farming tools, iron plows, hoes, etc., help farmers manually translate soil for cultivation, improve the efficiency of farming, and are related to the harvest of crops, which take root for the people. The tools used by craftsmen, such as axes, saws, chisels, and other tools, can carve wood and stone to build houses, build utensils, and promote the development of architecture and handicraft.
In terms of war defense, the weapons and armor made are extremely important. Weapons such as swords, gongs, and crossbows can enable soldiers to defend themselves against the enemy on the battlefield and defend their homes and countries. Solid armor can protect the bodies of soldiers and reduce casualties, which is related to the safety of the country and the peace of the people.
As for travel, carts and boats are important products. Carriages and ox carts can carry people and goods, and travel smoothly on land; boats can travel on rivers, lakes and seas, facilitating water transportation and promoting trade and cultural exchanges between regions.
Furthermore, in the living room, furniture products such as beds, tables and chairs are used for people to rest, work, eat, and create a comfortable living space. Candlestick lamps and the like are used in dark night lighting to disperse darkness and enable night activities to be carried out.
In short, the wide range of uses of products, whether related to the convenience of life, the promotion of production, or the stability of national defense, are closely related to people's lives and national development, and are indispensable.
What are the physical properties of the product?
There are many and many things that are rational, each because of its material and manufacture. The weight of things is measured by the weighing instrument, and the weight is measured by the weight. Those that are heavy feel heavy in the hand, and those that are heavy are easy to hold. Such as gold, heavy and heavy; kapok, soft and soft.
There is also the shape of things, or solid, or liquid, or tubing. Solid, there is a fixed shape, like a stone, like a tool, placed on the ground without changing its shape. Liquid, tubing and tubing, like water and oil, can flow. Those that are tubular, stuffed with the world, can not be seen, but can be felt by people.
Furthermore, the hardness of things is also different. The quality of gold and stone is to break down; and the quality of plaster is to break down. The quality of things also has its own quality. Gold is good, and the quality of fire is to be engraved; bamboo and wood are to be cut.
Light is also one of the things. Pearl and jade are of course, there is the light of the eyes; while the soil is of course, the color is dim. And the solubility of things is also poor. When it enters water, it melts immediately; while sand and gravel enter water, it sinks to the bottom and does not melt.
The quality of things is also important. The hemp is of high quality, and it can be stretched; and the tile is of high quality, and it can be folded. As for the magnetism of things, magnets can lead, but other things are not. This is the physicality of things, which is different. There is a great connection between people's lives and the fabrication of hundreds of workers, which cannot be ignored.
What are the storage conditions for the product?
The storage conditions of a man's things are related to the preservation and destruction of their quality and the long-term use. It is impossible to ignore them. Everything has its own suitability, and if you want to ensure its goodness, you must make it according to its nature.
Looking at all grains, they like dryness but hate dampness. They should be placed in a high-dryness place, and the ventilation should be smooth. If they are wet, they are easy to mold, and if they are closed, they will produce beetles. Therefore, the storage room should be selected with a high-pitched terrain, which can avoid water, and the walls are ventilated, which can disperse moisture. In this way, the grains will be safe and will not be damaged for a long time, so that they can be eaten by the people.
As for silk and the like, they are soft in nature and afraid of insect erosion. The method of Camphor wood has a fragrance and can repel insects; prickly ash leaves also have the effect of repelling insects. And it should not be placed under the scorching sun, lest its color change; and it should not be close to fire candles, afraid of its flammability.
Another word about the genus of ceramics is brittle and fragile. When storing, you must take care of it. Liner with grass tombs, cotton wool and the like to make it stable and do not let it touch and collide. When stacking, there are rules for the height and density, and they should not be messy to prevent collapse.
If it is a medicinal herb, each has its own nature. Or like yin, or like yang, or fear wind, or fear dampness. Such as ginseng and deer antler, which are expensive and perishable, must be stored in a porcelain bottle, sealed with wax, and placed in a cool and dry place. And aromatic medicines such as mint and patchouli should be sealed and hidden to prevent the aroma from dissipating.
Hardware, although solid, is easy to rust in case of moisture. Therefore, the storage place should be dry and damp-free, and it can be sprinkled with lime to absorb its moisture. And iron is especially afraid of being juxtaposed with copper, for fear of chemical changes and damage to its quality.
All in all, all kinds of utensils are different from each other because of their nature. Be a good operator, pay careful attention to physical properties, and observe their appropriateness, so that you can keep them in good condition for emergencies.
How safe is the product?
Looking at the safety of today's products, we should think about the principles of the ancient times to understand. In the past, all the workers made utensils with trepidation, so that things were good and safe. The safety of covers is related to everyone's livelihood and personal life, how can we not be careless?
The good work of the ancient times, the selection of materials must be fine. For wood, choose the one with a strong and straight texture to avoid cracking in the future; for gold, seek its pure quality without complexity, so that the utensils are strong and durable. The same is true for today's products. The quality of raw materials is the foundation of safety. If inferior materials are used for profit, such as building rooms on sand, their collapse will be quick.
At the time of production, there were ancient laws and regulations, and the process was rigorous. The craftsman followed the pattern and did not dare to slack in the slightest. Every job is related to the integrity of the utensils. Take sword making as an example, from smelting, hammering, hardening, to grinding, step by step carefully, so that the blade can be sharp and tough without hurting the hand. In today's production, although the equipment is different from the past, the rules of the process cannot be abolished. If the steps are omitted and shoddy, can the product be safe?
Furthermore, the method of inspection is also important in the past. After the finished product, it must be carefully examined. Observe its shape to see if there are any flaws; try its use to see if the function is complete. There are many products today, and the responsibility of inspection is even more heavy. When using scientific law and rigorous attitude, check one by one, and do not let unsafe products flow into the market.
Be careful, the safety of the product is not the responsibility of the sole worker. Merchants who sell it should also check its quality. If they sell it knowing that there is a danger, it is unjust. Users should also be cautious and use it according to their own laws. In this way, workers, merchants and users all fulfill their responsibilities, and the safety of the product can be guaranteed. Therefore, in order to ensure the safety of the product, it is necessary to choose fine materials, make it carefully, inspect it strictly, and everyone shares their responsibilities, so that they can be safe.
