The "14th Five-Year" Development Guide for the Petroleum and Chemical Industry particularly emphasizes the need to accelerate the development of new chemical materials, and the self-sufficiency rate of new chemical materials at the end of the "14th Five-Year" period will reach 75%, accounting for more than 10% of the overall chemical industry
Materials are the foundation of the manufacturing industry.
To accelerate the implementation of the strategy of making a strong country, we must consolidate the important foundation of new materials
A few days ago, the China Petroleum and Chemical Industry Federation issued the "Petroleum and Chemical Industry "14th Five-Year" Development Guidelines", which particularly emphasized the need to accelerate the development of new chemical materials, and proposed that the self-sufficiency rate of new chemical materials at the end of the "14th Five-Year" 75%, accounting for more than 10% of the overall chemical industry
"New chemical materials are used in many important areas of the national economy, such as aerospace, electronics, new energy, medical and health, energy conservation and environmental protection, etc.
" Jiang Zhongyi, a professor at the School of Chemical Engineering of Tianjin University, said that the future needs to build an independent innovation system for new chemical materials to accelerate The domestically-made new materials are put into use, giving more market support to the new chemical materials
New chemical materials can be used from airplanes to warm clothingNew chemical materials can be used from airplanes to warm clothing
From airplanes, rockets, satellites, high-speed trains, ships and other “heavy tools” related to the national economy, to daily necessities such as shopping bags, lunch boxes, batteries, and warm clothing, they are all closely related to new chemical materials
One end is connected to technology and innovation, and the other is connected to industry and market.
The research and development level of new chemical materials and the scale of industrialization can be said to be an important indicator of a country's technological and economic strength
Jiang Zhongyi introduced that, generally speaking, materials that require chemical reactions or chemical processes are called chemical materials
New chemical materials refer to new chemical materials that have been developed recently and are under development that have excellent properties or certain special functions that traditional chemical materials do not have
"Compared with traditional chemical materials, new chemical materials have the characteristics of light weight, excellent performance, strong functionality, high technical content, and high added value
" Jiang Zhongyi, for example, said that aircraft fuel consumption is related to its own weight, and the airframe is lighter.
In some fields, we must rely on new chemical materials to meet new technological needs
For example, the manned work capsule of a spacecraft needs to transform and process the carbon dioxide exhaled by the astronauts.
In addition, in many fields, the application of new chemical materials is of great significance
Professor Zhang Sheng of the School of Chemical Engineering of Tianjin University said that technological innovations in the energy sector, such as the clean and efficient conversion of traditional fossil energy, and breakthroughs in key technologies such as the sustainable conversion and utilization of carbon dioxide, will become an important driving force for China's energy revolution
The typical chemical processes of production, conversion, storage and utilization of energy and its derivatives are closely related to catalytic reactions.
The rapid growth of my country's chemical new material industryThe rapid growth of my country's chemical new material industry
The "2020 China Chemical New Materials Annual Development Report" released at the end of last year showed that China's chemical new materials industry has grown rapidly and has made significant technological progress.
It has become the fastest growing industry in China's chemical industry
During the "Thirteenth Five-Year Plan" period, major progress was made in the adjustment of the new chemical material industry structure, and about 10 new chemical material characteristic industrial parks with an annual output value of over 10 billion yuan were formed; the organizational structure of the company became more reasonable, and about 30 specialized industrial parks were cultivated.
Leading key new materials companies or enterprise groups in sub-industry fields have cultivated about 300 single champion companies specializing in new and special subdivisions; innovation capabilities have been significantly enhanced, and new chemical materials companies’ scientific research investment accounted for the proportion of their main business income.
Over 3%, a batch of national-level new chemical material research and development platforms and enterprise technology centers will be built
"High-performance carbon fiber and its composite materials are the material basis for realizing the construction of major national projects such as satellite platforms, carrier rockets, large aircraft, and weapons and ships
" Zhang Sheng said that the development and engineering of basic (T300) carbon fiber is already in progress in China.
According to reports, in the field of environmental protection, China has applied ultrafiltration membrane technology to water treatment.
For example, industrial wastewater contains a large amount of toxic substances.
If not properly treated, it will pose a threat to the basic survival of animals, plants and humans
Traditional wastewater treatment has problems such as waste of resources, excessive energy consumption and complex processes.
Zhang Sheng introduced, another example is that implantable medical devices have a special function of maintaining life and repairing
"In recent years, domestic research teams have developed chitosan-based composite materials that are integrated with 3D technology
Using 3D printing technology, the nano-hydroxyapatite/chitosan/polycaprolactone porous ternary composite scaffold material has been prepared.
It can be made into bone defect products that meet the individual needs of patients
Although data show that China has become a “material power”, it still has a long way to go to become a “material power”
Jiang Zhongyi believes that to build a “material power”, an independent innovation system must be built
Take membrane materials as an example.
Although they have not yet moved into industrial applications, some membrane materials have now emerged in the laboratory's research level
Although it is a partial lead, in the future, the introduction of such materials may lead the world
