What are the chemical properties of this product? This is a key question related to the essential characteristics of the product. Today's imitation of "Tiangong Kaiwu" is answered in the form of ancient proverbs.
Everything has its unique chemical properties, and this product is no exception. It may be stable, and under ordinary circumstances, it can maintain its own shape and structure for a long time, and it is not easy to react with the surrounding objects. Like the quality of gold and stone, it does not change its shape over time, keeping its true nature.
Or it is lively, and it changes rapidly when encountering some specific things. If saltpeter encounters fire, flames rise in an instant, bursting out with great power. If this product has such active chemical properties, care must be taken when applying it to avoid contact with unsuitable objects to prevent accidental changes.
Furthermore, it may be soluble. In a specific solvent, it can gradually melt and mix with the solvent. Like salt in water, it dissolves and exists in it. This solubility, in many processes and applications, may play an important role in various delicate productions.
And its chemical properties may be affected by environmental factors such as temperature and humidity. Increased temperature may increase its reactivity; increased humidity may cause its slow qualitative change.

In short, this product is widely used. In today's world, it is like the ancient craftsmanship. It penetrates into all aspects of people's life, work and study, bringing many conveniences and benefits to the world.

The method of making this product is related to the key to the creation of utensils. This imitation of "Tiangong Kaiwu" answers in classical Chinese.
Where utensils are made, the first material is selected. The quality of the material is related to the quality of the product. Such as casting swords, choose fine iron, and its texture is tough, so that it can become a sharp blade. After the selection of materials is completed, it is the order of processing. Or calcining, or beating, or smelting, each according to its material properties and product needs. Taking a copper caster as an example, the copper material is first placed in a furnace, smelted with fierce fire, and turned into a copper liquid. This is the method of turning the material into a liquid.
Then, according to the shape of the utensils, it needs to be shaped by mold or hand. If pottery is made, the craftsman kneads the clay blank by hand, or rotates it with the help of a pottery wheel to make it take shape. When it is ready to be shaped, it is fired in the kiln. The control of the kiln temperature is crucial. If the temperature is too high, the utensils are easy to deform and crack; if it is too low, the texture is loose and unusable. When firing, the heat needs to be accurately grasped, or simmered slowly, or attacked urgently, depending on the material and use of the utensils.
Furthermore, in the process of combining, the cooperation of various skills is also indispensable. Such as woodworking utensils, the mortise and tenon are connected, and they need to be tightly sewn to be strong and durable. And the processing sequence of different parts is also exquisite, first big and then small, first primary and then secondary, orderly, so as to obtain the best utensils.
There are decorative methods to add brilliance to the utensils. Or carve patterns, or apply paintings, or inlay jewelry, so that the utensils are both practical and ornamental. The engraver, like a pen, outlines the pattern on the wood and stone; the painter, with accurate color matching, applies colors according to the shape of the utensils, and creates a beautiful vision.
In short, the method of product synthesis requires excellent selection of materials, orderly processing, proper technical cooperation, and appropriate decoration, so as to make a good product for people to use and pass down for a long time.

During the storage and transportation of a certain goods, many precautions need to be considered in detail.
During storage, the first environment is suitable. If it is perishable goods, such as fresh fruits and vegetables, it is necessary to ensure that the storage place is cool and well ventilated, and the temperature and humidity must be precisely controlled. "Zhou Li · Tianguan Tsukazai No. 1" has a saying: "The people who cook are in charge of six animals, six beasts, and six birds, and they are distinguished by their names and objects. All the things that die fresh and die are the food of the king, and the things that are ashamed to be recommended to him, and the food of the later and the prince." It can be seen that the preservation of ingredients has been considered in ancient times. Another example is that flammable goods, such as oil, gunpowder, etc., should be stored away from fire sources, fireworks are strictly prohibited, and complete fire protection facilities should be equipped to prevent accidents.
Furthermore, the placement of goods is also exquisite. It needs to be arranged in an orderly manner according to the category, specification, weight, etc. Heavy goods are placed on the bottom to prevent dumping and injuring people; light goods are placed on the upper level for easy access. Similar goods should be placed in a centralized manner, so that it is not only convenient to take stock and check, but also easy to take out of the warehouse.
As for the transportation link, safety and stability are the top priority. If it is a long-distance transportation, check the means of transportation in detail before departure to ensure good performance, such as vehicle brakes, tires, ship engines, etc. " Tiangong Kaiwu says: "If the boat is difficult to moor in the wind, the whole body is tied to the anchor." Anchors are crucial to the safety of the boat. In the same way, the reliability of the means of transportation is related to the safety of the goods.
In addition, the transportation of different goods also has special requirements. Fragile goods, such as porcelain, glass products, etc., must be properly packaged, filled with soft cushions, such as straw, cotton wool, etc., and the driving should be stable to avoid bumps. For the transportation of dangerous goods, it is necessary to strictly follow relevant regulations, transport personnel must undergo professional training, and vehicles must also have obvious signs and protective measures.
All in all, in the storage and transportation of goods, every detail cannot be ignored, so as to ensure the safety of the goods and avoid accidents.
