Disodium 2,2'-(E)-Ethene-1,2-Diylbis(5-{[4-(Ethylamino)-6-(Phenylamino)-1,3,5-Triazin-2-Yl]Amino}Benzenesulfonate)

What are the main uses of these utensils? The use of utensils is related to people's livelihood and is also described in detail in "Tiangong Kaiwu".
The utensils in the world have various uses, either for the needs of life or for production, and each has its own function. In terms of daily life, many utensils are convenient for people to eat, rest, travel, etc. Such as kettles and retorts, used for cooking, to make food cooked and beautiful, to nourish the body. Tables, chairs and beds, for people to sit and sleep, to enjoy comfort. The genus of boats and carriages, it is beneficial for people to travel on land and water, or to transport goods, all of which are in the four directions.
In terms of production and labor, utensils are also indispensable. Farming has such things as scorpions and ploughshares, which help farmers cultivate the soil and sow the harvest, which is related to the harvest and is the foundation of people's livelihood. The utensils used by craftsmen, such as axes, saws, hammers, etc., can be carefully crafted to create objects, so that the skills of hundreds of workers can be displayed and all kinds of exquisite objects can be produced.
Furthermore, in the occasion of ceremonial sacrifice, utensils also play an important role. Ding Yi Zun Juan and the like are solemn and elegant, carrying the ritual of sacrifice, worshiping the ancestors of the gods, showing the heart of reverence and traditional etiquette. Bell and drum instruments, playing music and singing, create a solemn and peaceful atmosphere in the sacrificial celebration.
To sum up, the use of utensils is mostly related to the prosperity of the family and the country, and the small one affects the life of the individual. Whether it is practical, convenient for people's livelihood; or symbolic, inheriting cultural etiquette. No matter what kind of use, they are an important part of human life and social development, complementary and indispensable.

There are many kinds of chemical properties of things, each with its own differences. In terms of common things, metals are mostly active. Iron is prone to rust when exposed to water and oxygen. This is a change in oxidation, and its quality is gradually lost. Copper also has this kind of property, but compared with iron, it is slightly slower. Gold and silver have stable chemical properties and are not easy to combine with other things, so they often exist in the world without decay.
As for non-metallic things, they also have their own properties. Carbon can be used as fuel, burning and oxygenating, generating carbon dioxide, and generating hot light. Phosphorus is active, and white phosphorus has a very low ignition point and often burns spontaneously, so it must be kept carefully.
Acids are mostly corrosive. Hydrochloric acid, sulfuric acid and the like, when they come into contact with other things, can erode their surfaces. In case of metals, or hydrogen generation, they are synthesized into salts. Alkalis are opposite to them and also have their own characteristics. Sodium hydroxide is strongly alkaline, can dissolve oil, and touches the skin, causing serious damage.
Salts are produced by the combination of acid and alkali, and their properties are also diverse. Sodium chloride, a daily seasoning salt, is also stable. Copper sulfate, blue in color, can be used for sterilization, and is also commonly used in chemical experiments.
Among gases, oxygen is necessary for biological respiration, and its combustion-supporting properties are significant. Hydrogen, light in weight, flammable, combustion products are water, clean energy. Nitrogen, which accounts for most of the air, has a peaceful nature and is often used as a protective gas to prevent oxidation of other things.
The chemical properties of various things, whether active or stable, follow the laws of nature. Knowing it, you can make good use of it, for people's livelihood, for industry, and for everything, and avoid its harm. Therefore, the chemical properties of objects are the most important.

The production process of this product is very delicate, contains the essence of ancient craftsmanship, and is unique.
At the beginning, the selection of materials must be carefully selected, as "Tiangong Kaiwu" says "beautiful materials produce good products". Its quality needs to be high, and its sex should be appropriate, in order to lay a good foundation for subsequent processes. For example, in porcelain making, the soil must be delicate and pure, and its color and quality are related to the appearance of the finished product.
Later, the work of shaping is also crucial. Craftsmen need ingenuity and skills, or kneading, or carving, or forming with the help of utensils. Taking wood carving as an example, according to the shape and quality of the material, the craftsman has a plan in his heart, and the knife moves with his heart, turning the log into a lifelike state, with smooth lines, accurate proportions, and full charm.
Furthermore, in the process of firing or calcining, the control of the heat is the top priority. Just as "Tiangong Kaiwu" said that the beauty of the heat "is lost in the slightest, and it is a thousand miles away". If the temperature is too high, the shape will be destroyed, and if it is too low, it will not achieve its effect. For example, when a sword is cast, high temperature calcination makes the iron quality better, and then it is quenched, and the rigidity and softness are combined, and the sword becomes a sharp weapon.
The art of decoration is also indispensable. Or paint with color pictures, or engrave with patterns The porcelain painter uses the pen as a blade to sprinkle Dan Qing on the porcelain surface, and the flowers, birds, fish and insects, and the scenery of the characters jump on it; the engraver is meticulously carved, and the lines are dense and dense, showing the beauty of complexity.
Finally, the finished product needs to be strictly inspected, and the defects must be removed to ensure that the pieces are all high-quality products. In this way, the craftsmanship is interlocked, so that the best products can be produced, and the blood and wisdom of the craftsman can be passed on to the world.

The use of utensils is related to all things. When using them, be aware of many things to pay attention to.
The nature of the first heavy utensils. Each utensil has its own characteristics, whether strong or brittle, or resistant to temperature or moisture. If an utensil that is not fire-resistant is placed on an open flame, it will be damaged. It is the first thing to know its nature before use. For example, if pottery is used to make medicine, it is necessary to know that its heat transfer is slow but its temperature resistance is limited. If the heat is too urgent, it will crack easily.
The second is the method of operation. The method of operating the utensil has its own specifications. If a bow and crossbow are used, the force of pulling the strings and the direction of the arrow are all determined. Improper force will not only fail to hit the arrow, but also damage the crossbow. For example, if you use an axe to chop wood, you need to follow the texture of the wood. If you reverse it, the axe is easy to be dull and the wood is difficult to break. If you operate it properly, the utensils can be used to the best of their ability.
Furthermore, the protection of utensils. Maintenance after use is related to the life of the utensils. After the sword is used, you need to wipe the blade and apply grease to prevent rust. After using agricultural implements, wash the soil and place it in a dry place to keep it from breaking for a long time. If you maintain it properly, the utensils are always new, and you can use them handy next time.

It also has the importance of the environment. The environment in which the utensils are located affects their performance. Iron is easy to rust and rot in humid places; calligraphy and painting are easy to Therefore, when choosing a suitable environment to use utensils, such as hiding ancient books in a cool and dry place, so that the paper will not decay quickly.
When using utensils, be cautious, know the nature of the utensils, the method of operation, pay attention to maintenance and choose suitable use, in order to make the utensils do their best, use them for a long time without damage, and everything goes well.

Looking at the products of this world, their market prospects are like sailing on a boat in the sea, with unpredictable waves, and opportunities and challenges.
In today's world, technology is new, and everything changes. The rise and fall of products often depends on the changes of the times. Ruofu products should meet the needs of the times and the desires of the people. Like a boat with the wind, they must travel quickly, and their cities must be wide. In the past, when there were no cars and horses, people mainly walked, and traffic was stagnant. And the art of car-making flourished, and the products of cars were born in time and flourished in the city. Because of their convenience, they met the needs of everyone to travel. This is an example of a product that follows the trend and is favored by the market.
However, the market is fickle, like the change of the situation, it is difficult to observe. Even if there is a good product, if the situation is not judged, it may be buried. The ancient workers were all good at their skills, but due to the change of the world, the things they made were not suitable for the needs of the new era, so the skills were lost, and the products disappeared in the market. And today's market, competition is like a forest, hundreds of schools of thought contend. Products of the same kind, compare the good and the bad, and make an opinion. If the product does not have unique quality and excellent ability, it is difficult to stand out and occupy the top of the market.
And the good of the people, it is not static. Sometimes it is simple, sometimes it is practical, sometimes it is beautiful. The design of a product must check the hearts of the people and overcome the changes in their likes and dislikes, so that it can thrive in the city. If you adhere to the old regulations and do not think about innovation, you can use the old products to meet the demands of the new era. If you are like a boat to seek a sword, it will be inevitable if it does not meet.
To sum up, the market prospect of a product is related to the luck of the times, the demands of the people, and your own quality and change. Be good at observing the changes of the times, studying the needs of the people, and constantly seeking new changes, the product can ride the wind and waves in the sea of the market and set sail.
