16 years of continuous research! Sinopec creates "gold wire" to break foreign blockade and monopoly!

After 16 years of research, Sinopec has broken through key core technologies such as polymerization, spinning, and engineering amplification, including problems that many domestic research teams have been unable to attack for a long time. Finally won the para-aramid technology with independent intellectual property rights, developed the mysterious "gold wire", broke through the foreign technology blockade in one fell fell, filled the domestic gap.

On November 20, 2019, SINOPEC's "Ten Dragons" research project - "Development of complete set of technology for thousand-ton level counterpoint aramid industrial demonstration device" passed the identification in its Yizheng Chemical fiber. The expert group agreed that the project as a whole reached the international advanced level.

What is "gold wire"?

Have you ever heard of the mysterious "golden wire"? It's a high-tech fiber, golden in color and expensive, Cambi gold.

It has ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight and excellent performance. People figuratively compare it to "bullets can not penetrate, fire can not burn", the name of this fiber is called para-aramid fiber.

Aramid fiber and carbon fiber, ultra-high molecular weight polyethylene fiber and known as the three high-performance fibers, in the national defense military industry and civil industry have a wide range of applications, is a powerful and strong military strategic materials.

What products can be made?

Products made of "gold wire" arylon fiber are widely used in optical fiber and cable, rope webbing, skeleton materials, composite materials, friction sealing materials, textile and security protection and other fields, and its standard is body armor.

The body armor made of aramid fiber, weighing only 1.5kg, can withstand and disperse the energy of bullets and shrapnel several times higher than the steel plate, and can resist the continuous fire of light machine guns.

As the "pyramid" in the field of fiber materials, China's high-performance fiber industry started late, and there is a big gap between the technical level and large-scale production capacity and developed countries.

High-performance fiber production technology has been blocked by Western countries in the past. With the development of China's national defense and national economy, the demand for high-performance fibers will become more and more large. Internationally, product prices are rising, and the application of domestic high-performance fibers in national defense and special fields is also subject to foreign supplies.

To this end, breaking the foreign blockade and monopoly, and vigorously developing the high-performance fiber industry has become a main direction of China's chemical fiber industry.

In the face of such superior performance materials, some netizens exclaimed: "The next military parade will be able to wear golden nails all over the city."

About Yizheng chemical fiber

Yizheng Chemical Fiber Company is China's modern chemical fiber and chemical fiber raw material production base built and developed since the reform and opening up, and is now a high-end polyester and special fiber research and development and production base of Sinopec. For 41 years, the factory has produced more than 44 million tons of polyester chemical fiber products, which can add 80 sets of "Dacron" new clothes for each person in the country.

In 41 years, many firsts have been created

The first "borrow to build a factory"

In April 1978, Yizheng chemical fiber Base was listed as a project to introduce a complete set of new technologies.

On July 4, 1978, the preparation leading group and the preparation headquarters of Jiangsu Petroleum Chemical Fiber General Plant officially started the preparation. Negotiations on "three links and one level" and equipment introduction began rapidly.

In November 1980, Yizheng chemical fiber project was forced to suspend construction. Yizheng chemical fiber builders emancipate their minds and dare to be the first, in the case of only 300 million yuan allocated by the state, a total investment of 1 billion yuan was built through internal and external borrowing.

At that time, Zhang Yaohua, deputy commander of the preparation headquarters of the Ritualization project, drafted a "situation report".

In 1981, China International Trust and Investment Corporation issued 10 billion yen bonds in the Japanese financial market to raise the necessary funds for the first phase of Yizheng Chemical Fiber project.

Yizheng Chemical Fiber created the first state-owned enterprises "borrow to build factories, debt management", this unique way of investment and construction, known as the "Yizheng model".

The first domestic spinning production line with an annual output of 15,000 tons

Yizheng Chemical Fiber phase I project has a total of 16 polyester staple fiber production lines with an annual output of 15,000 tons. The overall use of Japan's Toyo textile technology. In order to reduce the introduction of investment, with the strong support of the state, Yizheng chemical fiber only introduced 2 production lines as a whole, and the remaining 14 lines adopted the method of technology and trade cooperation, introduced foreign technical drawings, manufactured equipment by domestic manufacturers, and cooperated to tackle key problems.

In December 1984, the first production line of Yihua Polyester Plant was completed and put into operation

From the conversion of drawings in August 1982 to the successful commissioning of the first domestic spinning line in July 1985, it took only three years to complete the key task. In April 1986, the key project with an annual output of 15,000 tons of polyester staple fiber passed the appraisal committee organized by the relevant departments. Thus, China has entered a new era of using domestic large-scale, complete sets of chemical fiber equipment to equip chemical fiber industry.

In 1985, the spinning production line of Yihua Polyester Factory was put into operation

In 1990, Yizheng Chemical fiber I and II projects were fully completed and put into operation, forming an annual production capacity of 500,000 tons of chemical fiber and chemical fiber raw materials, accounting for 1/3 of the national synthetic fiber output, 1/2 of the polyester output, equivalent to 1/8 of the national cotton output, to provide 5 meters of cloth per person per year, add a set of "Dacron" new clothes, Become the largest production base of chemical fiber and chemical fiber raw materials in China.

In October 1990, the first and second phases of Yizhua Project were fully completed and put into operation

The first production line with an annual output of 12,000 tons of polyester hollow fiber

Native polyester hollow is Yizheng chemical fiber polyester series product family members "rising star". In 1990, Yizheng Chemical Fiber introduced an annual production line of 4,000 tons of polyester hollow, which opened the prelude to domestic polyester hollow production. In August 1994, Yizheng Chemical Fiber built the first domestic 3D crimped polyester hollow production line with an annual output of 12,000 tons through technological innovation, becoming the country's largest 3D crimped polyester hollow production line.

In November 1994, Yizhua Polyester Plant No. 3 was put into production

The first bottle-grade polyester chip certified by "Double Cola"

Few people know that the bottles of "Coca-Cola" and "Pepsi" are made from bottle grade slices of our Yizheng Chemical fiber company.

On April 20, 1998, Yizheng Chemical fiber "White" brand bottle grade polyester chip obtained foreign FDA/EEC quality certification, becoming the first product to obtain this quality certification in China, and obtained the "admission ticket" to enter the international market; 

On December 15, 2000, Yizheng Chemical Fiber passed the "Pepsi Cola" certification, which also made Yizheng Chemical fiber become the first domestic enterprise that passed the "Coca-Cola" company and "Pepsi Cola" company product dual certification.

The first set of annual output of 100,000 tons of domestic polyester production equipment

Since the 1980s, China's polyester industry is developing rapidly, but the process equipment and technology of Chinese polyester enterprises have become the "expo" of "foreign equipment", which is subject to the long-term situation and the sustainable development of China's polyester industry is disproportionate.

Polyester field

In 1992, Yizheng Chemical Fiber combined with East China University of Science and Technology, Institute of Textile Science and Technology and Nanhua Group Machinery Factory to introduce polyester equipment for 30% capacity improvement; In 1997, Yizheng Chemical fiber organization implemented China's first set of 100,000 tons/year of domestic polyester project complete sets of equipment and technology projects, the project was listed as the national "ninth Five-Year" major technical research projects and Sinopec "ten dragons" science and technology research projects.

100,000 tons per year polyester complete set technology

On December 8, 2000, the project successfully started a feeding, completely broke the monopoly of foreign technology, ended the history of the introduction of foreign technology in China's polyester industry, created a road for the construction of polyester equipment, greatly reduced the technical threshold and investment cost of polyester project construction, and led to the leapfrog development of China's chemical fiber industry. The project has won the second prize of National Science and Technology Progress and the first prize of China Petrochemical Science and Technology Progress.

The first domestic polyester device was successfully started in one feed

The first annual output of 300 tons of dry spinning

High performance polyethylene fiber industrial production line

The production technology of high-performance fiber has been blocked by Western countries in the past and embargoes have been imposed on other countries. With the development of China's national defense military industry and the national economy, the demand for high-performance fibers will become more and more large, while international prices continue to rise, and the application of domestic high-performance fibers in national defense and special fields is also subject to foreign supplies. Therefore, vigorously develop the high-performance fiber industry, break the foreign blockade and monopoly, further enhance China's military equipment strength, and promote the industrial upgrading of the national economy, which has become a main direction for China's chemical fiber industry to promote independent innovation, transformation and upgrading.

After Yizheng Chemical fiber, Textile Science Institute, Nanhua Research Institute joint research, in 2008, the first set of 300 tons/year dry spinning high performance polyethylene fiber industrial production line in Yizheng chemical fiber was completed and put into production, breaking the foreign technology monopoly, the product reached the international level, making China the third country to master this technology and achieve industrialization. Since 2011, the first set of 1000 tons/year dry spinning high performance polyethylene fiber industrial production line has been completed and put into operation in Yizheng Chemical Fiber.

At present, Yizheng Chemical fiber has 4 ultra high molecular weight polyethylene fiber production lines (trade name "Lilon"), the output reached 3300 tons/year, the variety expanded to more than 50.
