    As a leading 4-Iodopyrazole supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

    What are the main uses of 4-iodopyrazole?
    Those who make firecrackers are the ancient ones. Their main users are just to drive away evil spirits and celebrate festivals.
    Looking at the records in "Tiangong Kaiwu", "All gunpowder is mainly saltpeter and sulfur, supplemented by grass and wood ash. The nitrate is yin, and the sulfur is yang. The two gods of yin and yang meet in a seamless and tolerable way. When they come out, the characters are fascinated, and the soul is scattered and the soul is powder." This is the principle of gunpowder used in firecrackers.
    In the past, the mountains were infested with evil ghosts, and people used bamboo tubes to set fire, and the sound of the explosion was used to exorcise the charm of ghosts. And in later generations, the art of gunpowder was the essence of the sun, and the paper-wrapped medicine was used for firecrackers. The bang of the imam, the sound of the burning, shook
    Every new year, the peach talisman is renewed, the sound of firecrackers is heard, the filth of the old year is removed, and the joy of the new year is overflowing. This custom has been practiced for a long time, because the sound of firecrackers is like thunder shaking the sky, and people are at peace when they hear the evil sound. And on the day of festivals, firecrackers are set off to help entertain, fireworks are bright, and the sound is continuous. Everyone is happy together, and the atmosphere is warm. Firecrackers are also used in weddings and funerals. Firecrackers are used to add joy and celebration to marriage, and the spirit of the deceased is sent away in mourning. Because the sound of firecrackers can express one's heart and communicate yin and yang.
    As for the army, the sound of firecrackers can also help the army's prestige and startle the enemy's courage. When the drums of war are sung in unison and firecrackers Therefore, the use of firecrackers is used to exorcise evil spirits and pray for blessings, festivals, express feelings, and strengthen military prestige. In our country's customs and culture, it is heavily occupied and has been passed down for thousands of years.
    What are the synthesis methods of 4-iodopyrazole?
    The method of making a cannon is like that in ancient times. "Tiangong Wuwu", one of the first methods is to make a clay mold. First, the mold is made of clay, and the shape of the cannon is carefully carved to make it refined. The mold needs to be resistant to high temperatures and not shaped. Molded, dried to remove its moisture and solidify it., the molten liquid is melted with high temperature to flow freely, and slowly injected into the mud mold. When the liquid is cold and solidified, carefully remove the mud mold, and the gun body is first broken. This method still needs to be polished to make the gun body smooth and remove defects to ensure that the gun body is shot.
    The second method is the loss method. First, the material is used to form the model of the gun. The mold needs to be refined, and it must be studied in detail. Then, the clay is applied outside the mold, and then added to form an outer mold. When the clay is dried and hardened, it is added as a whole, so that the material melts and flows out, leaving the hollow pottery. Then the liquid is injected into the pottery, and when it is cold and formed, the pottery is smashed, and the cannon is completed. The gun body caused by the loss method is clear, the surface is smooth, and the accuracy is high.
    The third is the manufacturing method. To form a mold, the cannon needs to have good resistance and dimensional accuracy. When the liquid is put into the mold, the production efficiency can be improved because it can be reused. However, it is necessary to control the liquid degree, injection speed and other factors in order to produce good products.
    The above methods each have their own advantages. The clay mold manufacturing method has low cost and is suitable for the manufacturing of large guns. The loss-making method has high precision and can produce fine guns. The efficiency of the standard manufacturing method is low, and it can meet the needs of a certain mold. The wisdom of the ancients was excellent, and they did not change the construction of the gun, and promoted the development of weapons.
    What are the physical properties of 4-iodopyrazole?
    The cannon is a sharp weapon of fire attack, and its physical reason is very special. The material of the cannon is mostly made of different materials. It is determined by its solidity and weight, and it can bear the force. This is because of its high-quality shooting, the explosion of the main fire, and the huge force is generated. If the material is not good, it is not necessary to do so.
    The weight of the gun is very large, which is not in vain. Heavy, placed on the top of the gun, it is not easy to be moved due to the force of the seat, so as to ensure the accuracy of the target. And the thickness of the gun body can also resist the attack of the square gun, increasing its survivability in the field.
    The ball of the gun also has its own characteristics. The ball is many, shaped and heavy. Shape, in the process of travel, can reduce the air resistance, so that the operation is more difficult, and the range can be increased.
    The source of the gun's power, its ignition is rapid, and it can release a lot of energy instantaneously, resulting in heavy damage.
    The source of the gun's power, its ignition is rapid, and a large amount of energy can be released instantaneously. This high-pressure push shot out quickly, and the power is low. The nature of fire requires dryness and speed, and the energy can be released evenly, so that the power of the gun can be fully reduced.
    Furthermore, the shooting angle of the gun is relative to the range. The angle of the whole gun body can make the gun move differently. The elevation angle increases, the range can be increased, and then the road is curved; the elevation angle is small, the road is low and flat, and the range is short. This is all due to the laws of physics. Those who need to understand this principle in order to use the power of live cannons.
    What are the chemical properties of 4-iodopyrazole?
    Firecrackers, fire nitrate, sulfur, charcoal powder and other synthetic materials. Its chemical properties can be particularly studied.
    Fire nitrate, that is, potassium nitrate, is the key component of firecrackers. Potassium nitrate has strong oxidizing properties, and can react violently with carbon and sulfur when firecrackers are ignited. Under high temperature conditions, it decomposes oxygen, providing a combustion-supporting agent for combustion, making the reaction proceed rapidly.
    Sulfur is flammable. Its ignition point is low, and when it is excited by moderate heat, it starts to burn. When sulfur is burned, sulfur dioxide gas is produced. Although it has a pungent smell, it is an important part of energy release and material conversion in the firecracker reaction system. Its oxidation-reduction reaction with potassium nitrate and carbon promotes the process of firecracker explosion.
    Charcoal dust is also indispensable. Charcoal is flammable and acts as a reducing agent in firecracker reactions. Combined with oxygen in potassium nitrate, carbon dioxide and other products are generated, and a large amount of heat energy is released at the same time. This heat energy causes the gas to expand rapidly, causing the crust of the firecracker to burst under pressure, emitting sound and flame.
    Mix the three in an appropriate proportion and make firecrackers through ingenious craftsmanship. When the fire source is touched, the strong oxidation of potassium nitrate triggers the violent combustion of sulfur and charcoal dust, instantly releasing a huge amount of heat energy and gas. The gas expands rapidly, generating a strong impact force, and then becomes the scene of firecrackers bursting and flashing. This chemical change is the core of traditional pyrotechnics, which contains the ancient people's exquisite understanding and application of the chemical properties of matter, and has been passed down to this day, adding a lot of joy to the festival.
    What is the price of 4-iodopyrazole in the market?
    In today's market, the price of sugar varies depending on the product, place, and time.
    If the usual caramel is yellowish in color and soft in texture, its taste is glycol, and the price per catty is about ten to dozens of texts. This sugar is mostly boiled with grain, and the process is not complicated. It is quite common in ordinary people's homes to season and make cakes, so the price is also close to the people.
    To be like sand sugar, white as frost in color, fine particles, its taste is sweet, and the price is higher than that of caramel. It may take dozens to hundreds of texts per catty. The production of sand sugar is slightly more refined than caramel sugar, and its quality is pure. It is mostly used for the diet of wealthy people, ordering tea, and for the production of exquisite snacks in pastry shops. It is difficult to make because of its large number of users, so the price is high.
    What's more, rock sugar is also. Its crystal clear, like ice crystals, and its taste is especially sweet. The production method of rock sugar is complicated, and it needs to be refined with sand sugar. It takes a long time and requires a lot of work, so the price is the highest. It may cost more than 100 yuan per catty, and it is easy to buy by ordinary people. It is often used by doctors as medicine, or by the rich to maintain health and make delicacies.
    And husband, the price of sugar is different in the big city of Tongdu and the small city of remote areas. In the capital of Dayi, merchants gather, the circulation of goods is convenient, the supply is sufficient, and the price may be slightly flat; in remote towns, the transportation is inconvenient, and the transportation of sugar is difficult, so the price is often higher. At the time of the New Year, the use of sugar increases sharply, the supply exceeds the demand, and the price also rises; and in normal seasons, the supply and demand are relatively balanced, and the price may be stable but less variable.
