PYRIDINE-3-CARBOXAMIDE OXIME

As for the chemical structure of the sun flintlock, although the ancient books did not specify it in modern chemical terms, it should be reasonable in today's scientific view.
Yang flintlock is mostly made of copper. Copper is also a metal with good thermal and electrical conductivity. Its production, or smelting and other techniques, make it into a specific shape. Its surface is smooth, this is one of the keys. Smooth surface can better concentrate sunlight, causing light and heat to concentrate.
From the perspective of chemical structure, copper reacts slightly in the air or with oxygen, etc., and the surface may form substances such as copper oxide. However, this change may not be deep into the interior, and the effect of its fire-making function in the solar flint needs to be carefully investigated.
The crystal structure of copper makes its atoms arranged in an orderly manner. This ordered structure may play a role in the transfer and convergence of light and heat. When sunlight shines on the solar flint, the energy of photons is absorbed and partially converted into heat energy. The structure of copper is conducive to the conduction and concentration of heat, causing the local temperature to rise, reaching the ignition point of flammable materials, and then starting a fire.
Although the ancients did not analyze the structure of the sun flintlock in detail with modern chemistry, it was a great move to create this object with wisdom and use the energy of nature. The chemical structure of the sun flintlock is based on the characteristics of copper, and its surface changes and crystal structures work together to make fire. It is a model of the ingenious combination of ancient technology and nature.

To the three, the medicine of realgar and realgar, its main users, cover all kinds of things.
Realgar has the ability to detoxify and kill insects. Ancient doctors often used realgar as medicine to treat sores and poisons. If a person is injured by insects and snakes, swelling and venom suddenly arise, and realgar is applied to it to relieve its poison and eliminate its swelling. And in the matter of exorcising insects and evil spirits, realgar also has strengths. During the Dragon Boat Festival, there are folk who sprinkle realgar in the courtyard and corners to drive away snakes, insects, rats and ants, and keep the house peaceful.
Realgar also has the effect of detoxification, but it is slightly different from realgar. Realgar is often used in the disease of scabies and exerts its medicinal power. The disease of scabies, itching is unbearable, and orpiment is used as medicine, which can be dry and wet to kill insects and relieve its symptoms. And because of the bright golden color of orpiment, in ancient times, it was also used for the correction of calligraphy and painting. Ancient books, calligraphy and painting, if there is a mistake in the pen, use orpiment to paint it, which can cover the original characters and re-write, so there is a saying of "nonsense", which is its different function in the cultural field.
The two are also highly valued in the art of alchemy. Ancient alchemists pursued immortality, using realgar and orpiment as raw materials to refine medicinal pills. Although their pursuit of immortality was not fully successful, they also made certain contributions to the exploration of chemical drugs.
In short, realgar and orpiment, either used for medical treatment, or for the protection of insects, or for the correction of calligraphy and painting, were important in many aspects of ancient life.

In the past, there were clouds in "Tiangong Kaiwu", and the sun was made of copper. The copper cover is made of metal, and its quality is warm and moist, and it has the ability to conduct light and heat. It is suitable for making fire.
At the beginning of making the sun, the refined copper is first selected. The copper whiskers are pure but not impurities, and if there are impurities, it will affect the effect of light guide and focusing. After the copper is selected, it will be molten and cast. When it is molten, the heat is very important. If the fire is intense, the copper liquid will flow away without shape, and if the fire is small, the copper will be difficult to melt. The fire must be even, and the copper will melt like a hum, before it can be cast. < Br >
When casting, make a concave mold. The curvature of the concave surface is studied according to the ancient method, and it needs to be precisely fitted, so that it can concentrate sunlight at one point. Pour the molten copper into the mold, and let it cool and form. After forming, the sun flintlock appears.
However, this is not fully finished, and it still needs to be polished. The work of polishing is meticulous. With a delicate stone, gently wipe the surface of the sun flintlock, so that it is as smooth as a mirror. After polishing, dip a soft cloth in oil and wipe it repeatedly to make it glow.
Made of the sun flintlock, when used, when the sun is sunny, take the sun flintlock to the sun, and place it in the focus of the sun flintlock with flammable things, such as moxa velvet. After a while, the moxa velvet ignited when exposed to light and heat, and then became a fire. The system of covering the sun flintlock, the ancients used ingenuity and the characteristics of copper to gather sunlight and make fire in nature, which is really the crystallization of wisdom, which was of great benefit to life and production at that time.

The sun flintlock is an ancient device for taking fire. Its nature is gold, round and concave, with copper as it is, and its color is golden yellow and moist.
In terms of its physical properties, the sun flintlock is reflective. Its surface is smooth like a mirror, and light can reflect objects, which can concentrate light rays in one point. This converging light is very hot. Under the clear sun, the sun flintlock faces the sun and adjusts its angle, so that the sunlight gathers on flammable things such as moxa velvet, and it takes a moment to generate fire. This is to use the principle of reflection and focusing of light to gather scattered light energy in one place to achieve the purpose of making fire.
Furthermore, the sun flintlock is hard in texture. It is made of copper and is wear-resistant. After years, although there are rust marks, its basic form and function are not easily damaged. Its properties are stable, unlike wood that is perishable and stone that is fragile. And copper flintels can better maintain their physical characteristics under different climatic environments, and do not lose their ability to gather light and make fire due to cold and heat.
The shape of the sun flintlock is round and concave. The round one, taken from the sky, has the meaning of perfection and cycle; the concave one, can converge, so that light can enter and not disperse. This unique shape is in harmony with the optical principles of physics, and it is not random. The ancients viewed the images of heaven and earth, observed the wonders of physics, and made this sun flintlock to meet the needs of life, which is enough to see the wisdom of the ancients. Its use of light and heat was of great significance in the society at that time, and it made great contributions to the progress and development of human life.

There are many things to pay attention to when using triethanolamine. Triethanolamine is mild in nature, but be cautious when operating.
First, it is about protection. When using, be sure to wear suitable protective equipment, such as gloves, goggles, etc. Because if it accidentally touches the skin, or causes skin allergies and itching; if it splashes into the eyes, it is particularly harmful and can damage the eye tissue, so protection must not be sparsed.
Second, about storage. It should be stored in a cool, dry and well-ventilated place. Keep away from fire and heat sources, because of its flammability, in case of open flames and hot topics, it may cause fire risk. And it should be stored separately from oxidants, acids, etc., to prevent mutual reaction and deterioration of ingredients.
Third, the specification of use. Strictly follow the established operating procedures and precisely control the dosage. Excessive use, or affect the performance of the product, may also have adverse effects on subsequent processes. During the preparation process, mix evenly to ensure that it is fully integrated to achieve the best effect.
Fourth, environmental considerations. During use, pay attention to the impact on the surrounding environment. Although its toxicity is relatively low, it should not be discharged at will to avoid pollution to soil and water sources.
In short, when using triethanolamine, all aspects cannot be ignored. Only careful operation and proper handling can achieve the purpose of safety and efficiency.
