The Aramid Technology Has Matured &Nbsp, No Need To Import.

In 1999, a young man who was only 25 years old was entrusted with the task of leading a R & D team to overcome the technical difficulties of aramid (Aramid 1313), which was monopolized by the United States and Japan for a long time.

That year, he finished his master's degree from the polymer materials department of Dalian University of Technology and stepped into Yantai.

In 2001, the aramid project was included in the "fifteen" science and technology research project by the State Science and Technology Commission.

The R & D team headed by Song Xiquan chaired the national "fifteen" science and technology tackling project guidance project - "Aramid 1313 fiber industrialization technology development".

In May 2004, the spandex aramid project in Yantai was put into operation in the first phase, with an annual capacity of 500 tons.

In 2010, Yantai spandex company

Like every technology development team in the world, the team led by Song Xiquan does not pay for the day, not the month, but the year.

Yantai spandex ahead of Technology

Founded in 1987, Shandong Yantai spandex Limited by Share Ltd is the pioneer of China's special fiber business. After successfully conquering the spandex production technology, which is also monopolized by foreign giants, the forward-looking business operators invested huge sums of money in 1999 and set up R & D teams to overcome aramid technical difficulties.

10 years later, the "Yantai spandex" which has become a listed company has made the top priority in the production technology and product development of meta aramid (1313).

Aramid fiber is "aromatic polyamide fiber" in our country.

Aramid fiber occupies a very prominent position in hi-tech fiber materials.

Aramid, with its excellent properties such as flame retardancy, heat resistance, light weight, high strength, insulation and radiation resistance, is the world's three largest high-performance fiber with carbon fiber and Gao Qianggao mold polyethylene. It is an important strategic material for national defense and national economy.

Aramid fiber is not only a key material for national defense industry and national backbone equipment manufacturing, but also widely used in important fields such as structural enhancement, electrical insulation, personal protection and environmental protection. It is a key basic material of the aerospace industry, a booster of low carbon economy and green industry, and a patron saint of human life safety. Therefore, the development of China's aramid industry is of great strategic significance.

The interposition aramid and para aramid were invented and industrialized by the DuPont Co of the United States in 60s and 70s twentieth Century.

For a long time, only a handful of countries, such as the United States, Japan and the former Soviet Union, were able to produce, while the United States and Japan basically monopolized the global aramid market.

Aramid fiber has been listed as an important strategic material because of its special uses in military, technology and other fields. The production technology has been tightly blocked and trade has been strictly controlled.

Especially in recent years, with the development of local wars and the world's anti-terrorism situation, the situation of supply shortage has intensified.

Since 1960s, China has invested a lot of manpower, money and material resources in the research and development of aramid technology. However, there has never been a breakthrough in the key engineering technology. The demand for aramid in China is totally dependent on imports and is severely controlled by people.

The long-term shortage of aramid supply has largely restricted the healthy development of China's national defense, military, aerospace and other fields, and affected the technological progress and industrial upgrading of defense related fields such as security, protection, environmental protection, communication and other related fields.

In recent years, the domestic enterprises represented by Yantai spandex group have achieved a major breakthrough in the key technologies of aramid and para aramid, and initial achievements have been made in the construction of aramid.

Yantai spandex Group Co., Ltd. specializes in R & D and production of hi-tech special fibers. It has the national enterprise technology center and the only aramid fiber engineering technology research center in China, and is a state-level high-tech enterprise.

In the interview, the reporter learned that the aramid fibers are mainly used in the fields of high temperature filter materials, protective clothing, composite materials, industrial textiles and so on. The aramid fibers are mainly used in the fields of national defense industry, aerospace, personal protection, reinforced materials, friction sealing materials and so on.

In the past "11th Five-Year" period, Yantai spandex company always adheres to the idea of "development is the top priority", self pressurization, catch up with the development.

They adhere to the principle of "science and technology is the primary productive force", vigorously promote technological progress, increase investment in technological pformation and product development, continuously improve their capability of independent innovation, enhance their comprehensive strength and achieve better economic results.

Yantai spandex company has won the honorary title of "the top ten of China's chemical fiber industry competitiveness" for 4 consecutive years, of which 2008~2009 is the top ten of China's chemical fiber industry competitiveness.

Widely used aramid fiber demand increasing {page_break}

In high tech fibers, the aramid fiber has high performance: excellent heat resistance, long term use at 204 C, no melting, no aging, and good dimensional stability.

Super strong flame retardancy, belongs to the nature of self flame retardant fiber, will not spontaneously burn, melt or produce droplets in the air. When extremely high temperature occurs, the fiber will expand rapidly and carbonization, forming a unique insulation barrier.

Excellent insulation can make the mechanical and electrical products temperature and insulation performance reach H level (180 degrees Celsius).

The air pollution of cement and bituminous mixture is more serious than that of the high temperature smoke and dust filter in the heavy areas. The following are protection, special forces, combat clothing, Navy Combat clothing, special police forces for military training, fire protection clothing for police officers and firefighting, protective clothing for operators of petroleum and petrochemical, electric furnace, chemical industry, metallurgy, furnace, rescue and rescue workers, protective clothing for inflammable and explosive places, etc. Besides, industrial, steam car hose base, high temperature conveyor belt, pfer printing blanket, acoustic wave bomb cloth, copying equipment cleaning paper, outdoor equipment cover, etc., and finally, composite materials, electrical insulation materials, automotive interior decoration, thermal insulation and flame retardant and sound absorbing textiles for military civil aircraft. The main application fields of the subdivision aramid fiber are environmental protection. The use of aramid fibers is made into filter bags for iron and steel.

According to Ye Yongmao, vice president of China Chemical Fiber Industry Association, at present, the main manufacturer of aramid fiber in China is the spandex Limited by Share Ltd of Shandong, Yantai, whose capacity has exceeded 5000 tons / year; the Guangdong Xinhui Choi Yan joint-stock company has a capacity of about 2000 tons / year; Jiangsu Saint Europe (Suzhou) safety protection material Co., Ltd. has been working with Donghua University since 2005, and has built 500 tons of aramid insulation paper, 1500 tons / year aramid fiber production line, and is still in the two stage of expansion.

Ye Yongmao said, from the consumption situation, foreign aramid fiber is widely used, and there has been a big increase in recent years.

In 2003, the total amount was 18 thousand tons; in 2007, it was 22 thousand and 800 tons, and it was estimated to be 28 thousand and 600 tons in 2012.

The proportion of interaramid fiber used in electrical insulation materials, honeycomb structure materials, flame retardant fabrics, filter materials and other structures in 2007 is 51: 5: 21: 15: 8%; Western Europe is 37: 10: 20: 19: 14%; Japan is 40: 40:

At present, China is also mainly used for filtering materials.

However, in the field of protective clothing and synthetic paper, China has been growing rapidly in recent years.

At present, China's aramid production capacity has reached 8300 tons, and the market demand is expected to exceed 7000 tons (of which more than half of the filtration materials).

With the rapid growth of production and demand in China's new material field, China's aramid production capacity is expected to reach 15 thousand tons in 2015 and 20 thousand tons in 2020.

Intensify efforts to upgrade the overall level of industry

Meta aramid is a key variety in China, which is independent research and development, its industrialization technology is relatively mature, its market application prospects are broad, and needs to be planned and developed.

Experts pointed out that in addition to the need for further improvement of high temperature filter materials, especially in the field of special textile protective clothing, synthetic paper insulation materials and honeycomb structure materials, application research and development and market development should be increased.

China's aramid fiber has developed rapidly in recent years. Compared with the high performance fibers such as para aramid (1414) and carbon fiber, its core technology of industrialization is relatively deep, but the overall level is still different from that of developed countries abroad, and the quality varieties, application fields, equipment level and engineering capability have yet to be improved.

At present, especially in the field of application, we need to strengthen the development.

Vigorously developing the aramid fiber and the upstream and downstream products chain is not only in line with the national industrial policy, but also has positive significance for promoting the development of China's strategic emerging industries, accelerating industrial upgrading and national defense construction.

In a report submitted by the China chemical fiber industry association to the national development and Reform Commission and the Ministry of industry and information, the difference between China's aramid industry and the advanced level abroad is shown in the following aspects: first, the independent innovation capability and the research and development system are not perfect; due to insufficient investment, the research and development links of the industry are still very weak compared with those of foreign companies; two, the research and development ability of upstream and downstream integration in the application field is poor; three, there are still gaps in the key equipment, components, instrument and equipment, raw material and auxiliary quality level, and so on, and the four is brand, standard, quality, certification system and so on.

According to the report, during the "12th Five-Year" period, with the development of national defense industry, energy conservation and emission reduction and national economic development, the demand for key varieties of high-tech fiber materials such as aramid fiber will increase substantially. At the same time, the developed countries will also technically blockade and suppress the economy on the basis of strategic materials at the critical moment.

Therefore, we will increase integration and development efforts in key products, core technologies, key equipment and production layout.

Tracking and drawing on the latest technology development trends at home and abroad, we will further pform and upgrade the overall level of the existing industrial technology and equipment, aiming at the quality standards of foreign aramid and the related product chain standard system, focusing on the above level, reducing costs and expanding application, and comprehensively improving the industrial competitiveness of the market.
