(1) Electronic materials industry
With the rise of new energy, big data, artificial intelligence and other technologies, as well as the acceleration of new infrastructure projects led by 5G, the domestic electronic materials industry has made great progress, forming a relatively complete industrial system, the industrial scale has grown steadily, and the transformation and upgrading of high-end electronic materials products has accelerated. The electronic materials industry can be mainly divided into battery materials industry, semiconductor materials industry and display materials industry according to different downstream applications, and magnetic filtration equipment is widely used in battery materials industry and semiconductor material industry.
1) Battery material
With the global energy crisis and environmental pollution problems becoming increasingly prominent, the development of the new energy vehicle industry has been highly valued, through technological innovation, industrial transformation, new energy development and other means, the development of low pollution, low emission as the characteristics of the new energy vehicle industry, is an important way to achieve sustainable economic development.
In this context, with the "two-wheel drive" of "policy + market", the development of new energy vehicles in China has entered the fast lane, according to the latest statistics of the China Association of New Energy Vehicles, in 2022, China's new energy vehicles will continue to grow explosively, and the production and sales will be 705800,000 and 688700,000 units, an increase of 969% and 934%, maintaining the world's first place for 8 consecutive years. In addition, according to the statistics of the China Automotive Power Battery Industry Innovation Alliance, the cumulative output of power batteries in China in 2022 will be 5459GWh, a cumulative year-on-year increase of 1485%；The cumulative sales of power batteries reached 4655GWh, a cumulative year-on-year increase of 1503%；The cumulative installed capacity of power batteries is 2946GWh, a cumulative year-on-year increase of 907%。
It can be seen that at present, China's new energy vehicles have entered a period of comprehensive market-oriented expansion, with a world-leading market scale, a significant increase in brand competitiveness, and an increasingly optimized supporting environment. According to the China Association, in 2023, the total sales of new energy vehicles in China will be 9 million, a year-on-year increase of 35%, and the penetration rate of new energy vehicles in 2023 will also reach about 35%. In the next 3-5 years, China's new energy vehicle sales are expected to maintain a high growth trend of 30% to 40%, becoming the first country in the world to enter the 10 million level of annual sales of new energy vehicles.
The cost of new energy vehicles is mainly distributed in four parts: power battery, motor controller, vehicle controller and manufacturing and assembly, of which, according to the statistics of high-tech lithium battery, the cost of power battery accounts for more than 30%. After years of development, the production process of lithium-ion power batteries has become mature, in the context of a sharp rise in demand for new energy vehicles at home and abroad, lithium-ion power batteries as the core component of new energy vehicles, that is, the energy of new energy vehicles, its demand is also increasing year by year.
According to the data released by the Ministry of Industry and Information Technology, the national lithium-ion battery output will reach 750GWh in 2022, a year-on-year increase of more than 130%, of which the output of energy storage lithium batteries will exceed 100GWhThe output of first-order materials such as cathode materials, anode materials, separators, and electrolytes for lithium batteries was about 1.85 million tons, 1.4 million tons, 13 billion square meters, and 850,000 tons respectively, with a year-on-year increase of more than 60%.The scale of the industry was further expanded, and the total output value of the industry exceeded 12 trillion yuan. In addition to the field of new energy vehicles, lithium batteries have also accelerated their rise in energy storage fields such as wind and solar energy storage, communication energy storage, and household energy storage, and ushered in a growth window period, with the cumulative installed capacity of energy storage lithium batteries in China growing by more than 130% in 2022.
In terms of construction cycle, the construction cycle of new energy vehicles is relatively long, and it takes 134 weeks for new models to be sold from design, research and development, manufacturing to market sales, but now the major OEMs are making every effort to compress time and promote parallel projects, which can complete the construction of new models within two years.
The preparation process of battery materials is complex, and the iron removal link runs through the entire production process. The charging and discharging of the battery is mainly realized by the embedding and de-intercalation of lithium ions in the positive and negative electrode materials, and if this process is interfered by impurities in the material, it will have a negative impact on the performance and safety of the finished battery, especially the presence of magnetic impurities such as iron and nickel may lead to safety problems such as reduced cycle charging and discharging performance of the battery, perforation of the separator and even local short circuit**. Therefore, in order to improve the purity of battery materials, enhance battery performance and reduce safety risks, the production process of batteries must control the content of ferromagnetic impurities in battery materials. At present, magnetic filtration equipment has been widely used in the manufacturing process of battery cathode materials, anode materials, separators and electrolytes, as well as the positive and negative electrode batching, stirring, coating, rolling and slitting in the manufacturing process of battery cells.
2) Semiconductor materials
According to the WSTS World Semiconductor Statistics Organization, the sales scale of China's semiconductor market increased from 913 in 2014$7.5 billion grew to $192.5 billion in 2021, growing at a compound annual growth rate of 1123%。In addition, according to public data from the China Semiconductor Association, the scale of China's integrated circuit industry reached 1,045.8 billion yuan in 2021, of which 451.9 billion yuan was for IC design, 317.6 billion yuan for IC manufacturing, and 276.3 billion yuan for IC packaging and testing.
On the one hand, China's IC import and export has a huge deficit for a long time, chips are highly dependent on foreign countries, and high-end chips are heavily dependent on importsOn the other hand, according to the data of IC Insights, although China's IC self-sufficiency rate is generally on the rise, it is still at a low level, and the chip self-sufficiency rate needs to be improved urgently, and the long-term expansion demand is large. Therefore, domestic substitution in the semiconductor industry is a long-term trend, and the pace of expansion of domestic wafer factories is less affected by the short-term industry prosperity. According to the market growth rate of China's semiconductor industry and the growth trend of the downstream demand market in recent years, the Prospective Industry Research Institute estimates that the market size of China's semiconductor industry will grow at a growth rate of about 15% from 2022 to 2027, and the market size of China's semiconductor industry is expected to reach US$445.3 billion by 2027.
From the perspective of the construction cycle, the construction of semiconductor fabs generally takes 2-3 years due to the unique infrastructure requirements of the fab and the regulatory process necessary for large-scale construction projects. From 1990 to 2020, approximately 635 new semiconductor factories were built worldwide, with an average construction period of 682 days.
Semiconductor materials have many varieties, high quality requirements, small dosage, strict requirements for environmental cleanliness, etc., widely used in chips, LEDs and other electronic devices, its production process is complex, different, but part of the process links are common, such as crushing, cleaning, filtration and other processes in order to remove impurities, improve the purity of materials process. With the improvement of material purity standards in the manufacturing process of semiconductor materials, coupled with the fact that magnetic foreign bodies can affect the electrical properties and radioactivity of materials, magnetic filtration equipment has been introduced into its manufacturing process to remove ferromagnetic impurities doped with the materials themselves and ferromagnetic impurities brought in by the wear and tear of production equipment.
In addition, due to the special process needs of semiconductor packaging, it has extremely high requirements for the performance of packaging materials. After packaging, semiconductor devices need to be able to withstand lead-free reflow soldering of 260 after high temperature and high humidity treatment, and the packaging materials are required to not be related to the chip, base island, Therefore, electronic packaging materials such as silicone packaging materials and epoxy packaging materials, as the core raw materials of chip packaging, need to remove magnetic foreign bodies through magnetic filtration equipment to meet the increasing process performance and application performance requirements of customers.
As an indispensable supporting industry for the national strategic support industry, the semiconductor materials industry has put forward clear requirements for the localization rate of the national policy, the import substitution of the industry has ushered in huge development opportunities, and the localization process of semiconductor materials has accelerated. As a supporting equipment for semiconductor material manufacturing, magnetic filtration equipment will also benefit from the policy and financial support of semiconductor manufacturing localization and obtain new development opportunities.
To sum up, with the rapid development of China's electronic materials industry, it is expected that China's magnetic filtration equipment market will maintain a high growth trend in the next few years. In addition, with the continuous iterative upgrading of electronic material technology, the stock of magnetic filtration equipment in each link put into production in the early stage is difficult to meet the existing market demand in terms of production efficiency, product consistency, stability, etc., and the demand for a number of magnetic filtration equipment will rise through equipment renewal, and the demand for renewal and transformation will be strong in the future.
(2) Chemical industry
The chemical industry is an important energy and raw material industry, which plays a comprehensive basic supporting role in the economic industry chain, national defense and security, and people's livelihood and health. After decades of development, China has built a modern industrial system with advanced technology, complete categories and strong competitiveness. In the chemical industry, magnetic filtration equipment is widely used in inorganic chemical materials such as carbon black, ceramics, glass, cement, bricks, refractories, as well as polymer chemical materials such as plastics, rubber, fibers, adhesives, coatings, etc.
Carbon black belongs to the fine chemical industry, which is mainly formed by incomplete combustion or cracking of hydrocarbons, and is widely used in tires, plastic products, coatings, inks and other rubber products. The ferromagnetic content of carbon black products produced by the new production line is less, and with the extension of the production line, the ferromagnetic content will gradually increase, and the demand for the use of magnetic filtration equipment will also increase.
In the process of carbon black production, flue gas containing a large amount of water and corrosive components such as H2S and SO2 will cause serious corrosion to equipment and pipelines. The particle size of carbon black is very small, generally 20-80nm, and it has strong adhesion in equipment and pipelines, which accelerates the corrosion of equipment;Impurities such as iron oxide and iron filings produced by corrosion of pipelines and equipment directly enter carbon black products, seriously affecting the application of carbon black in pigment, conductive and rubber products. Magnetic filtration equipment is commonly used by various carbon black manufacturers to remove ferrous impurities from products.
In recent years, China's rubber, automobile and other industries have developed well, which has promoted the rapid development of the carbon black industry. According to data from Huajing Industry Research Institute, China's carbon black production capacity will be 925 in 202200000000 tons per year, a year-on-year increase of 1280%。
With the improvement of quality requirements and the expansion of carbon black application volume by carbon black application manufacturers, the application demand of magnetic filtration equipment, as an indispensable magnetic impurity treatment equipment in the carbon black production process, will maintain a growth trend in the industry.
(3) Food industry
Food is the most basic material condition for human survival and development, but with the development of human science and technology, the impact of trace elements in food on the human body has gradually attracted public attention. Magnetic metal objects such as iron filings brought in during food processing belong to foreign body impurities, which are different from the iron elements formed by the combination of organic molecules in animals and plants that the human body needs, and when such foreign substances enter the body with food, they will adhere to the stomach and intestinal wall, and the human body cannot digest and absorb them, which will cause harm to human health. Taking flour grain products as an example, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China stipulates in the "Wheat Flour" (GB T1355-2021) and "Corn Flour" (GB T10463-2008) that the magnetic metal substances in various wheat flour and corn flour shall not exceed 0003g/kg。At the same time, the "Detailed Rules for the Implementation of the Wheat Flour Production License" also made provisions such as "wheat flour must go through magnetic separation before entering the finished product packaging process". Therefore, magnetic filtration equipment has been used as an indispensable magnetic impurity treatment equipment in food processing and production processes.
Most of the equipment in all kinds of food production lines is metal equipment, and due to cost reasons, it is difficult to use all stainless steel equipment, which will be more or less rusty and small metal pieces and enter the finished product. If metal impurities cannot be effectively removed, the quality of food will be greatly affected, which in turn will affect the brand effect of the product and the reputation of the food manufacturer.
For example, grain will be doped with various metal iron impurities in a series of processes such as drying and drying, purchasing, logistics and transportation, and warehousing, so the iron removal process must be carried out before the bulk grain enters the transportation processIn the process of processing cane juice into white sugar, it passes through many iron pipes, which may be mixed with rust, and in order to improve the quality of white sugar products, it needs to be removed with magnetic filtration equipmentIn the process of salt processing, in order to protect the pulverizer, water pump, stirring blade, centrifuge, screw conveyor and other parts from damage, and ensure product quality, it is also necessary to remove iron and debris in the material.
In recent years, with the continuous progress of the national economy, residents' health awareness has gradually improved, China's food safety standards have been continuously improved, and the overall volume of China's food industry has also grown. Therefore, in the future, the application of magnetic application equipment in the food industry will also be further promoted, and the industry market potential is greater.
(4) Pharmaceutical industry
According to the data of China Business Industry Research Institute, the size of China's pharmaceutical market increased from 1,329.4 billion yuan in 2016 to 1,729.2 billion yuan in 2021, and is expected to grow to 2,991.1 billion yuan in 2030, with a compound growth rate of 628%。With the continuous improvement of the quality standards of China's pharmaceutical industry and the continuous development of the pharmaceutical industry, the market demand for pharmaceutical equipment in China is also growing. Magnetic filtration equipment is mainly used in the magnetic foreign matter screening process in the preparation process of drugs.
The drug directly acts on the human body, and the presence of trace magnetic impurities will not only adversely affect the performance of the drug, but also cause damage to human health due to potential toxicity when ingested into the human body. With the continuous development of detection methods, the control of metal foreign bodies in drugs has become an increasingly important problem for drug manufacturers. In order to avoid the adverse effects of metal foreign bodies on the quality of drugs, magnetic filtration equipment needs to be connected to the relevant process.
To sum up, the production process of downstream industries has continuously improved the quality requirements of materials, which will directly drive the application and development of magnetic filtration equipment. With the development of the economy, the improvement of policy guidelines and quality supervision requirements of downstream industries, China's magnetic filtration equipment will have good development prospects in the fields of electronic materials, chemicals, food and medicine in the future.
