In semiconductor manufacturing, even extremely small amounts of metallic ions, particle impurities, or organic contaminants can have catastrophic consequences. These impurities can alter the paths of electron transport within the chip, increase resistance, and lead to excessive heat generation and performance degradation. Impurities can also cause shorts and other issues, rendering the chip inoperable. According to relevant research, yield losses due to purity issues of chemical reagents in the chip manufacturing process can reach 20% - 30%, which is undoubtedly a significant challenge for the semiconductor industry, which pursues high precision and high output.     The key role of magnetic drive pumps in it In the entire semiconductor manufacturing process, magnetic drive pumps ensure the continuity of chemical reagent transportation. Their continuous and stable operation ensures the timely supply of chemical reagents needed for different processes, avoiding production downtime due to reagent supply interruptions. Taking the film deposition process as an example, it is necessary to continuously supply specific gases and liquid chemical reagents to the reaction chamber. The stable operation of the chemical pump ensures the continuity of the deposition process, allowing uniform film growth and ensuring the electrical properties and reliability of the chip.     As a type of chemical pump that is highly favored in the semiconductor industry, the biggest highlight of the magnetic drive pump lies in its unique design without mechanical seals. It uses a magnetic coupling to achieve power transmission, and the pump shaft and motor shaft interact with each other through magnetic force, without the need for traditional mechanical sealing devices. This fully sealed design is like putting on a strong "protective armor" for chemical reagents, fundamentally eliminating the possibility of medium leakage. In the semiconductor manufacturing process, even extremely small leaks can cause serious pollution problems, and the emergence of magnetic pumps perfectly solves this hidden danger. In the process of transporting photoresist, the magnetic pump can ensure that the photoresist flows stably in a closed pipeline without any leakage, thus ensuring the high purity of the photoresist. In the transportation of high-purity electronic-grade hydrofluoric acid, the fully sealed characteristics of the magnetic pump effectively avoid the contact between hydrofluoric acid and the outside air, prevent the volatilization of hydrofluoric acid and the harm to the environment and personnel that may be caused by leaks, and at the same time ensure that the purity of hydrofluoric acid is not affected, providing a reliable guarantee for subsequent etching processes.  

By the end of the Year of the Snake in 2025, Anhui Shengshi Datang Chemical Equipment Group Co., Ltd. will take the lead in sales and provide professional knowledge analysis from the technical department to reach a long-term cooperation with a group enterprise in Hunan to carry out projects.   The enterprise mainly produces organic chemicals, and a large amount of volatile organic compounds (VOCs) will be produced in the production process. In order to effectively treat these exhaust gases, the enterprise has adopted a waste gas treatment system mainly based on liquid absorption method. In this system, a centrifugal pump made of stainless steel material is selected as the circulating pump of liquid absorbent. The centrifugal pump made of stainless steel material has excellent corrosion resistance. Its large flow characteristics meet the needs of large-scale waste gas treatment for the amount of absorbent circulation. In actual operation, the chemical pump can stably extract the absorbent from the collecting tank at the bottom of the spray tower and transport it to the spray device at the top of the tower, ensuring the circulation speed of the absorbent and the spray effect. After the operation of the waste gas treatment system, the concentration of exhaust gas emission from the enterprise has been greatly reduced, reaching the relevant national environmental protection standards. It not only reduces environmental pollution, but also avoids the risk of high fines and production suspension due to excessive exhaust gas emission.   The components, corrosiveness, and temperature of the waste gas are important factors to consider when selecting a chemical pump. If the exhaust gas temperature is high, it will lead to the corresponding increase of the liquid absorbent temperature, which poses a challenge to the high temperature resistance of the pump material. In the treatment of exhaust gas generated by some high-temperature calcination processes, the temperature of the absorbent may be as high as 100℃ or more. At this time, the stainless steel pump of metal material can work normally in this high-temperature environment and ensure the circulating transportation of absorbent due to its good high-temperature resistance performance. However, the engineering plastic pump has limited high-temperature resistance, and it may have problems such as deformation and aging in this high-temperature condition, which will affect the normal operation and service life of the pump.   In the actual selection process, you can also refer to the performance curve of the chemical pump. The performance curve can intuitively show the changes of head, power and other parameters of the pump under different flow rates. By marking the actual required flow rate and head parameters on the performance curve, it is possible to select the appropriate model of chemical pump more accurately, ensuring that the pump operates under efficient and stable working conditions.  

Quartz sand, also known as silica sand, is a common non-metallic mineral raw material, mainly used in the construction industry, glass manufacturing industry, ceramic industry, and casting industry. With the development of China's economy and the increasingly tight energy situation, the country advocates the development of the solar photovoltaic cell industry, which will lead to a substantial increase in the demand for photovoltaic glass sand. Therefore, strengthening the research on quartz sand beneficiation and purification technology and deep processing technology is of great significance for meeting the silicon demand of high-tech industries and improving the utilization value of China's quartz sand resources.     Anhui Prosperous Great Tang Chemical Equipment Group Co., Ltd. undertakes the quartz sand purification project for the world's largest photovoltaic glass production project.     Today, let us enter the quartz sand purification site together and explore how Prosperous Great Tang helps this project.   Selection Parameters: Pioneering a New Track As a non-metallic mineral, purification is a necessary production process for quartz sand.

The "Unseen Heroes" in Pharmaceutical Intermediate Projects   In today's pharmaceutical field, pharmaceutical intermediates play a crucial role as the key link connecting basic chemical raw materials with active pharmaceutical ingredients (APIs) and finished drugs. They are the fine chemical pearls in the journey of pharmaceutical chemical raw materials towards APIs or finished drugs and are the key starting materials for the production of chemical APIs. It is no exaggeration to say that the synthesis quality and efficiency of chemical drugs highly depend on high-quality pharmaceutical intermediates.     Behind this prosperous development, the figure of chemical pumps emerges quietly and plays a vital role. The production process of pharmaceutical intermediates involves many complex procedures, from the transportation of raw materials, the formulation of reaction materials, to the transfer of finished or semi-finished products. Every link cannot do without the precise assistance of chemical pumps. Chemical pumps are like the "arteries" of the pharmaceutical intermediate industry, ensuring the smooth flow of materials and the efficient operation of the entire production chain. Next, let's explore together the outstanding performance of chemical pumps in various links of pharmaceutical intermediate production.   General Vanguard: Flexible and Efficient   Anhui Shengshi Datang Chemical Equipment Group Co., Ltd. uses magnetic pumps to transport fluids for customers' pharmaceutical intermediate projects. Magnetic pumps can be regarded as the "main force" among chemical pumps and are widely used in the field of pharmaceutical intermediate transportation. Its working principle is like a "rotating storm." With the help of a high-speed rotating impeller, the medium is rapidly thrown out under the action of force, thus generating a strong pressure difference to promote the continuous flow of the medium.   In the initial raw material transportation stage of pharmaceutical intermediate production, magnetic pumps, with their large flow rate characteristics, can efficiently transfer a large amount of basic raw materials from storage tanks to reactors quickly, providing timely materials for subsequent chemical reactions and greatly improving production efficiency. Moreover, the structure of magnetic pumps is relatively simple, making maintenance convenient. For continuously produced pharmaceutical intermediate factories, this can effectively reduce the time and labor costs of equipment maintenance and ensure the continuity of the production process. This large pharmaceutical intermediate enterprise selected efficient and energy-saving magnetic pumps for the transportation of various raw materials on its newly built production line. These magnetic pumps select suitable materials and sealing forms according to the characteristics of different raw materials, such as corrosiveness and viscosity. After running for a period of time, it was found that compared with traditional pumps, their transportation efficiency increased by about 20%, energy consumption decreased by 15%, and the equipment failure rate also decreased significantly, bringing considerable economic benefits to the enterprise.     In pharmaceutical intermediate projects, the media handled by magnetic pumps are diverse and have various characteristics. Therefore, it is crucial to select the appropriate media characteristics when choosing a pump. Pharmaceutical intermediate production involves many complex chemical reactions, and the media involved include some with strong corrosiveness, such as certain intermediate solutions containing acids and alkalis; some with toxicity, such as the volatile poisons emitted by some organic synthetic intermediates; and some media containing solid particles, such as the suspensions of some crystalline intermediates in the reaction process. If the material of the magnetic pump is not properly selected, in the face of corrosive media, the pump components may be rapidly eroded, resulting in a sharp decline in pump performance and even leakage risks, endangering production safety and product quality. For toxic media, if the seal is not tight, leakage will pose a serious threat to the health of operators. For media containing solid particles, if the wear resistance of the over-current components such as the impeller and pump casing is poor, wear will occur in a short time, affecting the normal operation of the pump. Therefore, for corrosive media, materials with excellent corrosion resistance, such as fluoroplastics and stainless steel, should be selected; for toxic media, it is necessary to ensure that the mechanical seal of the pump meets extremely high sealing standards to eliminate leakage risks; for media containing solid particles, pumps with strong wear resistance of over-flow components such as impellers and pump casings should be selected, or special open impeller designs should be adopted to effectively deal with the impact of solid particles and ensure the long-term stable operation of chemical pumps.   Operation and Maintenance Key Points: Prolonging Service Life Since pharmaceutical intermediate production is usually continuous operation, the reliability and stability of magnetic pumps are directly related to the "safety" of the entire production line. Once the pump suddenly fails and stops during production, the material transportation will be interrupted, the reaction in the reactor will get out of control, and a series of serious consequences will ensue, such as product scrapping, equipment damage, and even safety accidents.     Moreover, frequent maintenance not only consumes a lot of manpower, material resources and time but also disrupts the production rhythm and affects the economic benefits of enterprises. Therefore, when selecting a pump, priority should be given to well-known brands of chemical pumps that have been tested by the market for a long time, have a good reputation and a low failure rate. At the same time, pay attention to whether the structural design of the pump is convenient for daily maintenance, such as whether it is easy to disassemble and replace vulnerable parts, and whether it has online monitoring functions to give early warnings of potential failures and arrange maintenance in time to ensure that the magnetic pump always maintains an efficient and stable operating state and protects pharmaceutical intermediate production.   Regular maintenance is the "secret of health preservation." Develop a detailed maintenance plan according to the operating time and working conditions. At regular intervals, disassemble the pump body, clean the fiber residues and sediments in the impeller and pump casing to ensure the smoothness of the flow channel; check the condition of the mechanical seal and packing seal and replace the worn parts in time to prevent leakage. For vulnerable parts such as impellers, bushings and seals, establish a replacement warning mechanism, reserve an appropriate amount of spare parts according to the actual wear rate, and replace them quickly at critical moments to avoid long-term shutdowns due to minor failures and keep the magnetic pump always in "youthful vitality".
