[ Changzhou Jiayuan Chemical Co., Ltd. ] Deeply participates in fire safety publicity and builds a solid "firewall" for chemical safety

Recently, at a time when fire safety is of vital importance, [ Changzhou Jiayuan Chemical Co., Ltd. ] actively responded to the call and, relying on its own professional advantages and strong sense of social responsibility, fully and deeply engaged in fire safety publicity activities to safeguard the safety and stability of the chemical industry.As a chemical enterprise, fire safety is the lifeline of production and operation. Within the company, a high-standard and professional fire safety training took the lead. In the training room, senior fire instructors and internal safety experts of the company joined forces to open a knowledge feast for all employees. Unlike ordinary industries , chemical production involves many flammable, explosive, toxic and harmful chemicals. The training focuses on fire prevention and response in special chemical scenarios. The instructors analyzed typical fire and explosion accident cases of chemical companies at home and abroad, such as the fire in the park warehouse , and deeply analyzed the root causes of the accidents. From the storage temperature and humidity control of chemical raw materials, to the fire and explosion prevention and operation points of equipment such as reactors and distillation towers, to the emergency disposal process after the leakage of hazardous chemicals, every link was explained in detail. Employees eagerly absorbed knowledge, and many people took notes seriously, knowing that this knowledge was related to life and the survival of the company.The actual combat drill was even more thrilling. The fire scene in the chemical workshop was simulated, and orange smoke quickly filled the air, and the alarm sounded throughout the factory. Employees quickly evacuated according to the predetermined "chemical worker exclusive" evacuation route. This route fully considered factors such as the wind direction of chemical leakage and the height of the terrain to ensure that employees can escape safely in the most dangerous situations. During the evacuation process, everyone was proficient in wearing gas masks and wrapping important materials and equipment with fire blankets. The movements were standardized and rapid. After gathering in the safe area, the heads of each department counted the number of people and reported it as soon as possible. At the same time, the company's full-time fire brigade was dispatched urgently. They wore heavy fireproof clothing and operated professional chemical fire-fighting equipment, such as dry powder fire trucks and foam fire trucks. They took precise measures for different simulated fire sources and quickly extinguished the fire, showing strong emergency rescue capabilities, which doubled the confidence of the employees who were watching on the scene.  Fire safety propaganda can be seen everywhere in the company park. The bulletin board is replaced with a new chemical fire safety poster, which shows in detail the fire hazard signs, fire extinguishing methods and storage precautions of various chemicals; on both sides of the road, eye-catching slogans are hung, such as "Chemical fire prevention is no small matter, safety responsibility is heavier than a mountain" and "Strict operation to control the source of fire, protect the chemical lifeline", etc., to remind employees to tighten the safety string at all times. In the workshop, the rest area of each team is equipped with a fire safety manual, which is convenient for employees to read and study at any time and strengthen their daily fire awareness.The company organizes special training and exchange activities for partners, especially upstream and downstream companies that provide raw materials and transportation services to chemical companies. It shares the experience of fire safety management and control in the chemical production process, helps partners optimize their own fire safety measures, and reduces the fire risk of the entire industry chain from the source. For example, it emphasizes to transportation companies the fire prevention and anti-static requirements when tank trucks transport flammable and explosive chemicals, as well as the emergency response plan in case of emergencies.It is understood that in this fire safety publicity campaign, [ Changzhou Jiayuan Chemical Co., Ltd. ] has organized a total of 5 training sessions, covering a total of more than 1,000 employees, their families, and personnel from cooperative units, and distributed more than 1,000 copies of professional chemical fire safety publicity materials .

Rare gases have such a wide range of applications

Rare gases are a general term for gases such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). In the past, people believed that these gases did not react with other substances, so they were also called "inert gases."In fact, although these gases do not account for a high proportion in the air, they are indispensable in our modern life. In this issue, Jiayuan will talk about their common uses.1.As protective gasBecause the chemical properties of rare gases are very inactive, argon is often used as a shielding gas to isolate the air when welding precision parts or active metals (such as magnesium and aluminum) to prevent the metal from reacting with other substances at high temperatures.Iridium, the nuclear fuel of nuclear reactors, which oxidizes rapidly in the air, also needs to be machined under the protection of argon.In order to extend the service life of the light bulb, adding argon gas into the light bulb can reduce the evaporation of the tungsten filament and prevent the tungsten filament from oxidation.2. As an electric light sourceRare gases emit light of different colors when electricity is applied. The world's first neon light was made of neon. The red light emitted by neon has strong transmittance in the air and can pass through thick fog. Therefore, neon lights are often used as beacons in airports, ports, and water and land transportation routes. Argon or helium is filled into the tube, which emits light of light blue or light red when electricity is applied. Filling a mixture of helium, neon, and argon with different contents into the tube can make colorful neon lights.The commonly used fluorescent lamp is made by filling a small amount of mercury and argon gas in the lamp tube and applying fluorescent material (such as calcium halophosphate) on the inner wall. When the power is turned on, the discharge of mercury vapor generates ultraviolet rays in the tube, which stimulates the fluorescent material to emit visible light similar to sunlight, so it is also called a fluorescent lamp.When powered on, a high-voltage long-arc lamp filled with xenon can emit strong light that is tens of thousands times stronger than a fluorescent lamp. Therefore, it is called an "artificial little sun" and can be used for squares, stadiums, airports and other lighting. Neon lights, krypton gas, and xenon gas can also be used in laser technology.3. Medical treatment   Xenon lamps have high ultraviolet radiation and are used in medical technology. Xenon gas dissolves in cell oil, causing cell anesthesia and swelling, thereby temporarily stopping the action of nerve endings and achieving anesthesia. As an anesthetic without side effects, people have tried a mixture of 80% xenon and 20% oxygen.Isotopes of krypton and xenon are also used to measure cerebral blood flow, etc.4. Making Artificial AirHelium and oxygen are mixed into artificial air, which divers can breathe. Because in the deep sea with greater pressure, if you breathe with ordinary air, more nitrogen will be dissolved in the blood. When the diver rises from the deep sea and gradually restores the normal pressure in the body, the nitrogen dissolved in the blood should be released to form bubbles, blocking the microvessels and causing "gas stasis". The solubility of helium in the blood is much lower than that of nitrogen. If the above phenomenon does not occur, but the ordinary air is replaced by a mixture of helium and oxygen (artificial air). 5. InflationHelium is the lightest gas besides hydrogen. Hydrogen is flammable and explosive, while helium is a colorless, odorless, inert gas. It is chemically inactive. Generally speaking, it is difficult to react with other substances. Helium has been used to fill balloons and airships instead of hydrogen. 6. Can produce a variety of mixed gas lasersHelium-neon laser is one of them. Helium-neon mixed gas is sealed in a special quartz tube. Under the encouragement of an external high-frequency oscillator, inelastic collisions occur between atoms of the mixed gas, and energy transfer occurs between the stimulated atoms, resulting in electronic transitions and emitting stimulated radiation waves and near-infrared light corresponding to the transitions. Helium-neon lasers can be used for measurement and communication.7. Low temperatureThe boiling point of liquid helium is -269℃, which is the most difficult to liquefy of all gases. Using liquid helium, ultra-low temperatures close to absolute zero (-273.15℃) can be achieved. Liquid helium is an ordinary liquid with the properties of ordinary liquids. Liquid helium below 2.2 thousand is a superfluid with many abnormal properties. For example, it has superconductivity and low viscosity. Its viscosity is 1% of the viscosity of hydrogen. Liquid helium can flow upward along the inner wall of the container and then slowly flow along the outer wall of the container. This phenomenon is of great significance to the research and verification of quantum theory. In today's era of rapid technological development, rare gases have been widely used in many fields due to their unique and excellent properties. Whether in the lighting industry, they provide us with bright and energy-saving light sources; or in the electronic chip manufacturing process, they serve as key protective gases and etching gases to help produce high-precision chips; or in the medical field, they play an indispensable role in specific diagnostic and treatment methods; and in high-end technological frontiers such as aerospace, they provide guarantees for the stable operation of various precision instruments and equipment. Rare gases are everywhere, and their value is immeasurable. If you are eager to learn more about rare gas products and accurately grasp their application trends, you are sincerely welcome to come to our company for a detailed discussion . Our company has a professional team and rich industry experience, and can provide you with comprehensive and detailed rare gas products .

Hexafluorobutadiene: An emerging key material for the semiconductor industry

The semiconductor manufacturing process has extremely high requirements for etching gases. As chip manufacturing processes continue to shrink, the demand for high-precision etching is becoming more and more urgent. Hexafluorobutadiene (C₄F₆), as an advanced etching gas, plays an important role in the semiconductor etching process.1. Application advantages( 1 ) High etching selectivity : In semiconductor manufacturing, hexafluorobutadiene can etch different material layers with high precision. For example, when etching materials such as silicon dioxide and silicon nitride, it can selectively remove the target material with minimal damage to other materials. This is because the molecular structure of hexafluorobutadiene enables it to precisely interact with the chemical bonds of the target material during the etching reaction.( 2 ) Fine etching capability : Hexafluorobutadiene performs well in etching circuit patterns at the submicron and nanometer levels. It can achieve very fine line etching, which helps to improve the integration of chips. For example, in chip manufacturing with a process of 10 nanometers and below, hexafluorobutadiene can etch complex circuit structures to meet the manufacturing requirements of high-performance chips.       2. Economic and environmental benefits( 1 ) Reduce production costs : The use of hexafluorobutadiene can reduce side reactions during the etching process, thereby improving etching efficiency. This means that in large-scale production, the etching process time can be shortened and the operating cost of the equipment can be reduced. For example, compared with traditional etching gases, the use of hexafluorobutadiene can increase the production capacity of etching equipment by about 30%, which correspondingly reduces the etching cost per chip.( 2 ) Good environmental performance : Hexafluorobutadiene produces relatively few decomposition products during the etching process and has less pollution to the environment. Its global warming potential (GWP) is low and meets environmental protection requirements. In the context of increasingly stringent environmental regulations, the use of hexafluorobutadiene can help semiconductor companies meet environmental standards and reduce greenhouse gas emissions.        3. Challenges and solutions( 1 ) Supply stability : The production technology of hexafluorobutadiene is relatively complex, and there are currently few manufacturers in the world that can produce it on a large scale. Jiayuan is keenly aware of this, keeps up with market trends, and is more strict with itself in terms of production quality and production safety, so as to ensure stable supply of products while also guaranteeing product quality.( 2 ) Safe storage and transportation : Hexafluorobutadiene is a high-pressure gas and is somewhat dangerous. Safety regulations must be strictly followed during storage and transportation. For example, special high-pressure gas containers must be used and transportation vehicles must meet safety standards. At the same time, companies need to provide safety training to relevant personnel to reduce safety risks.We have a professional sales team and technical service team to provide customers with high-quality fluorine chemical products, good technical support, and a sound after-sales service system. Based on the principle of "customer first, integrity first", we provide high-quality products and services and go hand in hand with customers.

Magnesium fluoride coating: multi-field applications and excellent performance

The main purpose of coating is to reduce reflections and to improve the transmittance of the lens and the quality of the image. In modern lens manufacturing processes, the lens must be coated. Lens coating is based on the principle of optical interference. A layer of substance (usually fluoride) with a thickness of one-quarter wavelength is coated on the surface of the lens to minimize the reflection of the lens to the color light of this wavelength. One layer of film only works on one color light, while multi-layer coating can work on multiple colors of light. Multi-layer coating usually uses different materials to repeatedly coat different thicknesses of film layers on the surface of the lens. Multi-layer coating can greatly improve the transmittance of the lens. For example, the reflectivity of each surface of an uncoated lens is 5%, which is reduced to 2% after single-layer coating, and can be reduced to 0.2% with multi-layer coating. This can greatly reduce the diffuse reflection between the lenses of the lens, thereby improving the contrast and sharpness of the image.Magnesium fluoride coatingMagnesium fluoride is a kind of coating material. Magnesium fluoride crystal (MgF 2 ) belongs to the tetragonal system, with a melting point of 1255°C, high hardness, good mechanical properties, stable chemical properties, and not easy to deliquesce and corrode. Its main feature in optical properties is that it has a high transmittance in the vacuum ultraviolet band (the transmittance at 170nm is still above 80%). It is widely used in optical fiber communications, military fields and various optical components.Application of magnesium fluoride coatingThe main application of magnesium fluoride coating is coating on the surface of ordinary tempered glass, thereby improving the light transmittance of the tempered glass surface and achieving easy cleaning function, while also extending the life of the glass. AR coated glass can currently be mainly used in solar cell components, solar thermal, construction, automotive glass and other fields.Preparation of magnesium fluoride coatingMagnesium fluoride coating uses evaporation method, which is called evaporation coating by heating and evaporating a certain substance to make it deposit on the solid surface. This method was first proposed by Faraday in 1857 and has become one of the commonly used coating technologies in modern times. Evaporating substances such as metals, compounds, etc. are placed in a crucible or hung on a hot wire as an evaporation source, and the substrates to be plated such as metals, ceramics, plastics, etc. are placed in front of the crucible. After the system is evacuated to a high vacuum, the crucible is heated to evaporate the substance in it, and the atoms or molecules of the evaporated substance are deposited on the surface of the substrate in a condensed manner. The film thickness can range from hundreds of angstroms to several microns. The film thickness is determined by the evaporation rate and time of the evaporation source (or by the charge amount), and is related to the distance between the source and the substrate. For large-area coating, a rotating substrate or multiple evaporation sources are often used to ensure the uniformity of the film thickness. The distance from the evaporation source to the substrate should be less than the mean free path of the vapor molecules in the residual gas to prevent chemical reactions caused by collisions between the vapor molecules and the residual gas molecules. The high-quality glass is processed on one or both sides to have a lower reflectance than ordinary glass, and the reflectivity of light is reduced to below 1%. In the visible light range, the single-sided reflectivity of ordinary glass is about 4%, and the total spectral reflectivity is about 8%.Jiayuan has layout in both the upstream and downstream of the fluorine chemical industry chain, forming a complete fluorine chemical industry chain. At the same time, Jiayuan is also constantly conducting technological research and development and innovation, and has stronger competitiveness and market position in the production, sales and research and development of magnesium fluoride products.
