1. Project Overview 1. Project name: Absorbing material series products 2. Project Introduction 2.1 Advantages of Choosing Absorbing Material Series Products 2.1.1 Electromagnetic radiation has become the fourth source of pollution in our country. With the advancement of science and technology, the application of electromagnetic technology in the environment has created material civilization for society, but it has also brought people into a world full of electromagnetic radiation. in a radioactive environment. As early as 1975, experts predicted that with the development of urban economy and population growth, a large number of electronics, communications, computers, automobiles and electrical equipment have entered households, and the man-made electromagnetic energy in urban space will increase by 7% to 14% every year, which means that 25 It will increase by up to 700 times in the next year, and the urban electromagnetic environment in the 21st century will be more complex and deteriorated.
In the past 20 years, my country's economy and urbanization have developed rapidly. The electromagnetic environment in urban space has become more complex, and many new phenomena and problems have emerged. The main ones are: (1) Due to urban development and expansion, some radio and television stations and wireless communication transmitting stations are surrounded by residential areas, and some residential areas form strong field areas; (2) Mobile communication technology (including mobile communication, paging communication , cluster professional network communications) are developing rapidly, and a large number of mobile communication transmitting stations have been set up on high-rise buildings in cities. Although these electromagnetic radiation sources are not very powerful, they are blooming all over the urban area, which enhances the electromagnetic wave field strength at high altitudes in the city. In addition, There are also many microwave directional antennas, satellite antennas and short-wave antennas; (3) With the increase in urban electricity consumption and the implementation of power grid transformation projects, 110kV and 220kV high-voltage substations have entered the central area of ??the city, either indoors or outdoors, or on the ground or underground, causing Neighboring residents panic and complain; (4) The rapid development of urban transportation (cars, trams, subways, light rails, etc.) has caused an upward trend in electromagnetic noise; (5) The increase in personal wireless communication means and household appliances has increased the electromagnetic energy density in the home environment. Increase, the indoor electromagnetic environment and the outdoor electromagnetic environment are integrated, and the total amount of urban electromagnetic environment is constantly increasing.
Electromagnetic radiation refers to "the phenomenon in which energy is emitted from a source into space in the form of electromagnetic waves", and the electromagnetic environment is "the sum of all electromagnetic phenomena existing in a given place". The deteriorating electromagnetic environment not only causes harm to people's daily communications, computers and various electronic systems, but also poses a threat to people's health. Electromagnetic radiation is difficult to detect because it is invisible and intangible. As early as 20 years ago, experts pointed out in a report that took 9 years to complete the damage of electromagnetic radiation to biological bodies: millions of people are facing serious problems due to long-term exposure to electromagnetic radiation from cables and household appliances. The risk of cancer and degenerative diseases is increasing. High-frequency electromagnetic waves have extremely strong radiation damage to biological body cells, nervous system, circulatory system, immune, reproductive and metabolic functions, and have long-term potential threats and effects on the public health. , strong interference to household appliances, medical equipment, military facilities, and aviation may even cause catastrophic consequences. After years of research, the U.S. Environmental Protection Commission has found that long-term living in extremely low-frequency electromagnetic fields (such as power frequency 50Hz) may lead to the occurrence of certain cancers in humans. As various household appliances enter thousands of households, people's opportunities to come into contact with and be exposed to extremely low-frequency magnetic fields generated by household appliances such as refrigerators and electric blankets are gradually increasing, and the potential harm is gradually increasing.
As my country's electromagnetic environment deteriorates day by day, electromagnetic radiation levels in residential buildings and office buildings have a significant increase trend. Following air pollution, water pollution and noise pollution, electromagnetic radiation has become the fourth source of pollution in our country. Many electromagnetic radiation disputes have occurred in Beijing, Shanghai, Guangzhou, Shenzhen, Shijiazhuang and other places. At present, the electromagnetic radiation environment in our country is equivalent to the water pollution and air pollution in the 1960s. We must strengthen research now and take precautions. If electromagnetic pollution reaches the point where the environment cannot be tolerated, it will be difficult to develop the economy. For this reason, research on electromagnetic pollution prevention and control is urgent.
2.1.2 In the face of increasingly worsening electromagnetic pollution, in order to effectively reduce the damage of electromagnetic radiation to the human body and equipment, people have adopted many methods. Among them, the research and development of new materials that absorb electromagnetic waves have become more and more popular. Attention, customer resources are extremely rich.
2.1.3 The initial investment is small, the risk is small, it is quick to get started, and the cycle to enter the high-end market is short.
2.1.4 The technology is mature and does not require expensive R&D and patent fees.

4. New technology
The principle of absorbing materials is an energy conversion process. Through a large number of experiments, it was found that it has another use. It can absorb microwaves and quickly convert microwave energy into thermal energy. Its heating efficiency is extremely high. Its heating efficiency can be controlled by controlling the material composition and processing technology, thereby controlling the temperature of microwave-heated objects.
Widely used in: industrial microwave heating elements (an ordinary household microwave oven can melt glass in 2 minutes and can exceed 1000°C), heat conversion materials for microwave baking pans, microwave smelting, microwave incineration, other microwave heating components, etc. The heat absorption efficiency of materials tested by Midea, Galanz and Sanyo has exceeded that of Japanese materials.
Test results: The baking pan is placed on the bottom plate. The maximum temperature of the Japanese Sanyo baking pan is about 200℃, which is lower than the limit use temperature of Teflon 250℃, while the maximum temperature of the domestic baking pan is 285℃, which is high. The ultimate operating temperature of Teflon is 250℃.
5. Maturity of production technology and process
At present, the application of absorbing coatings in the civilian frequency band at home and abroad is still blank. (There are precedents for the application of absorbing coatings in the military frequency band in the United States and France) We have a series of civilian products that use the principle of absorbing waves It is the first of its kind in China. It is the first of its kind in China that rubber plate-like absorbing materials can be processed into coiled materials. The core technology of absorbing materials and absorbing coatings is the compatibility of materials. The production process is simple, and the processing equipment is all general-purpose equipment, so the one-time investment is small.
3. Market aspects
1. Domestic and foreign industry development trends
Stealth aircraft first appeared in the United States during the Gulf War. In China, the Commission of Science, Technology and Industry for National Defense organized relevant scientific research institutions to tackle key absorbing material projects. From 1993 to 1996, we took the lead in radar waves. The absorption frequency band has achieved the stealth technology of 40-meter military targets for vehicle-mounted radars and 400-meter military targets for bomber radars. We were also the first in China to launch absorbing rubber sheet products for civilian use 3 years ago. Absorbing coatings and absorbing materials are for civilian use. We are currently the only one making the protection series. With the discovery of absorbing materials, a variety of products will become available, thus replacing the current traditional and backward method of using metal materials to protect against electromagnetic wave pollution. As the amount of information increases, the frequency range is also widening. The advantages of absorbing materials are becoming more and more obvious due to their characteristics.
2． Domestic and foreign markets
The application of absorbing coatings has gone far beyond the scope of military stealth and anti-stealth, confrontation and anti-confrontation, and is more widely used in human safety protection, anti-electromagnetic interference, and safety in communication and navigation systems. Information confidentiality, improving overall machine performance, improving signal-to-noise ratio, electromagnetic compatibility and many other aspects. Absorbing paint is a type of material that can absorb electromagnetic wave energy projected onto its surface and convert it into heat energy through material loss (the principle of energy conversion). Among various electromagnetic radiation protection materials, coatings have become the best because of their convenience, light weight, no space occupation, and integration with the substrate. Because absorbing coatings can absorb excess electromagnetic waves, this not only reduces The interference of clutter on one's own equipment also effectively prevents the harassment and harm of electromagnetic radiation to surrounding equipment and personnel; moreover, the wave-absorbing paint can be easily applied on complex curved surfaces, tiny corners, holes, edges, etc. Form coating films accurately and firmly on precise and complex parts to meet the shielding and EMC needs of industrial, scientific and medical equipment.
Electromagnetic radiation protection of radio and television transmitting stations: Radio and television transmitting stations will cause strong field strength to the surrounding area. Utilize the absorption characteristics of electromagnetic radiation and use appropriate absorptive coatings to cover buildings in the higher radiation frequency band to attenuate the indoor field strength. In addition, the coating has shielding properties and is a shielding absorption coating with a shielding performance of 20 to 30dB in the range of 10MHz to 1.5GHz.
Protection against electromagnetic radiation from industrial, scientific and medical equipment: Industrial, scientific and medical equipment will produce a large amount of electromagnetic radiation during their work. If not handled properly, it will not only cause damage to their own working environment, but also It will also cause interference to surrounding equipment. The most obvious example is the secondary clutter problem within the machine. Secondary clutter often leads to disordered procedures in machines and equipment, leading to large deviations in scientific experiments and medical test results, thus bringing great resistance to scientific research and production, and even threatening human life. In addition, the electromagnetic radiation emitted by these devices can also cause harm to the health of operators. Therefore, it is necessary to protect industrial, scientific and medical equipment from electromagnetic radiation. Due to the high precision of industrial, scientific and medical equipment, higher requirements are also placed on electromagnetic radiation protection methods. In the selection of radiation protection methods, in addition to selecting low-radiation base materials and distance protection, the use of absorbing materials for protection is also one of the very important protection methods.
Electromagnetic radiation protection of household appliances: All electrical appliances, such as refrigerators, televisions, etc., will emit electromagnetic radiation during use, just because electromagnetic waves are an "invisible" substance, because electromagnetic waves are visible Invisible and intangible energy matter exists all the time and everywhere, so it is even more dangerous and harmful, and we are just not aware of it. With the implementation of 3C certification, the requirements for electromagnetic radiation protection are getting higher and higher. In fact, it is not difficult to take protective measures against electromagnetic radiation such as household appliances. It just requires a simple process to be added to the production process - Just spray absorbing material, but the choice of absorbing coating should be determined according to its frequency band.
Electromagnetic radiation protection of mobile phones and computers: With the development of science and technology today, while mobile phones and computers bring convenience to people, they also bring electromagnetic radiation hazards that cannot be ignored. In order to minimize the radiation of mobile phones and computers to the human body, especially the head, in addition to reducing the radiation power of the mobile phone as much as possible and ensuring that it does not come into contact with the human body when using the mobile phone, other protective measures should also be considered. The radiation frequency of the mobile phone is 800 to 1800MHz. Computers will also generate hundreds of megabytes of electromagnetic waves. If during the production process, absorbing paint with absorbing function can be sprayed on the inside of mobile phone casings, computer cases, and computer monitors to absorb excess electromagnetic waves, there will be no more There are problems with the hazards of electromagnetic radiation. Spraying absorbing paint is very simple. It will neither affect the aesthetic appearance nor increase the cost. As people become more aware of electromagnetic radiation, the market for radiation-proof products will become larger and larger.
For example: Green environmentally friendly chassis (the first in the world). Nowadays, the overall performance of computers is improving rapidly. The power of the main components inside the computer is constantly increasing, but at the same time, the amount of radiation from the computer host is also increasing. As we all know, electromagnetic radiation is extremely harmful to human health. Being in an environment polluted by electromagnetic radiation for a long time will cause people to suffer from adverse symptoms such as fatigue, memory loss, physiological function decline, etc. What’s even more frightening is that this kind of radiation damage is invisible and intangible. Even if you are harmed by computer radiation all day long, you will not be aware of it. Therefore, it is imperative to choose a chassis with high radiation protection performance. The current radiation-proof chassis technology is to shield electromagnetic waves. The purpose of shielding is to confine electromagnetic waves to a certain area. The difference is that shielding mainly uses the reflection of electromagnetic waves by conductive materials to limit the spread of electromagnetic waves. Generally, the entire radiation source needs to be shielded, otherwise it will weaken in one direction and increase in other directions. This is simple in theory, but in fact it requires very high process technology.
Wave absorption is the use of materials to absorb electromagnetic waves, so that the electromagnetic field energy of electromagnetic waves is converted into heat energy. The technical requirements for using electromagnetic wave absorbing materials are low. Research on EMC materials currently focuses on shielding materials, and there is relatively little research on electromagnetic wave absorbing materials. In fact, electromagnetic wave absorbing materials play an irreplaceable role in EMC technology such as shielding materials. The use of absorbing materials is simple and easy. No changes are required to the original design. Just spray 0.2 to 1.0 mm thick absorbing paint on the 2 to 6-sided surfaces in the computer case. In addition to the radiation protection function, the absorbing paint has the function of preventing radiation. There are even more unexpected effects.
Electromagnetic radiation protection in offices and residential areas: The applications of absorbing coatings in civilian products are not limited to these. Soon absorbing coatings will be applied to your daily life, such as: your office, By spraying absorbing paint in your home, there will no longer be the harmful problem of electromagnetic radiation. It will absorb and convert the electromagnetic waves (electronic mist) radiated by your office, household appliances, and office equipment in your home into harmless substances, and at the same time, Most of the external electromagnetic waves are absorbed and isolated, and it will be a very clean electromagnetic environment space.

3. Threat
The only acute problem is: currently, some past standards are rough and low, so that some areas with serious pollution do not exceed the standards, which brings great obstacles to pollution control. However, soon, In the future, the country will formulate scientific pollution standards. In addition, from the perspective of the cumulative effect of electromagnetic wave pollution, this risk will also be reduced.
