China'S PPF Industry Is Ready For Development.

Under the new situation of rapid development of global high technology,

It can be used for high performance materials in many fields.

The aramid fiber is also called aramid fiber II and aramid fiber 1414 in our country.

Because of its rigid macromolecular structure, high strength, high modulus, heat resistance, flame retardance and insulation, it can be widely used in aerospace, aviation, protective clothing, tires, mechanical rubber products, friction products and gaskets, cables, personal protection and other fields.

In the aerospace and Quartermaster industry, the large aircraft has two structures. The aramid paper or basic honeycomb composite materials can be used as cabin doors, windows, wings, fairing surfaces, ceilings, bulkheads, etc. solid rocket motor shells and spaceship cockpit of missiles can be made of aramid paper or basic honeycomb composite materials; bulletproof vests, helmets, bulletproof armoured vehicles and banknote trucks can be used in the interlayer of aramid fibers.

In the information industry, para aramid fiber can be used as "tension component" in optical cable. Special circuit board made of aramid nonwoven fabric and resin is characterized by thermal deformation, light weight and low dielectric constant.

In the rubber industry, para aramid can be used as a conveyor belt for mining. In industrial rubber pipes and oil field exploration pipelines, the base cloth and rubber compound are used as reinforcement. The aramid fiber characteristics are applied to the special working environment. The aramid fibers are mixed with rubber compound to make the mixed rubber on the tread of the tire to increase strength, friction and heat.

In the coated fabric, the counterpart aramid fabric is used to replace the vinyl polymer coating on the boat boat through the polyurethane Chu layer. The counterposition aramid fiber on the tethered balloon can increase the balloon strength; the opposite Aramid Composite Structure in the fan blade has the characteristics of light and high strength; in the protection layer of the bulletproof vest, the counterpart aramid fabric is fixed after the column.

In the automotive industry, para aramid can produce brake shoes, clutch, shock absorber and top grade automobile shell made of aramid fiber, which can reduce body weight, reduce fuel consumption and increase crashworthiness.

Expand production capacity and break foreign monopoly

According to experts, from the production point of view, the global capacity of aramid fiber in 2000, 2005 and 2009 is 38000 tons, 50000 tons and 72000 tons respectively, and the capacity is expected to reach 86000 tons in 2010.

From the investment situation, the international and DuPont Co have announced the expansion plan in the last five years, and the capacity is expected to increase by 25%.

In 2005, the Korean company realized the industrialization of aramid fiber with a capacity of 800 tons / year, then expanded continuously, and reached 3000 tons / year in 2010.

In 2008, the Korean Hyosung Corp also achieved the industrialization of aramid fiber, with capacity of 500 tons / year, and it is expected to expand to 2000 tons / year in 2010.

At present, the domestic construction or construction of the aramid project has been put into operation in October 2009 in Chengdu Lan Chenguang Chemical Research Institute's 1000 tons / year; in August 2009, the Pingdingshan Pingmei Shenma Group of 500 tons / year was put into operation in August 2009; the Suzhou trillion trillion Fiber Technology Co., Ltd. in August 2009 was put into operation in October 2009 for 1000 tons / year; the Yantai spandex Limited by Share Ltd, which was commissioned in the two quarter of 2011, was 1000 tons / year.

In addition, there are also 3000 tons / year of Sinopec, Yizheng chemical fiber Limited by Share Ltd, and 500 tons / year of Hebei Chemical Industry Co., Ltd. in Hebei.

In the interview with Yantai spandex Limited by Share Ltd, who took the lead in tackling the aramid fiber crisis, reporters recently learned that para aramid fibers have more advantages than aramid fibers in terms of high temperature resistance, flame retardancy and insulation. They also have high strength -- 5~6 times of steel; high modulus initial modulus is 4~10 times of the polyester industrial yarn; the thermal stability at zero shrinkage at 150 degrees C is zero, and the outstanding strength of 65% can be maintained at 260 degrees.

Yantai spandex group formally launched the project of "aramid industrialization technology development" in 2004. In 2008, it built the first 100 ton class continuous running production line in China, filling the domestic gap, breaking the monopoly of foreign technology, and passed the technical appraisal of Shandong provincial science and technology department.

The aramid pilot products have been applied in the field of hose skeleton, reinforced base cloth, packing seal, optical fiber cable reinforcement and so on.

As a listed company, Yantai spandex starting investment project 1000 tons of aramid industrialization project, is also a national 863 project project, will be put into operation in the two quarter of this year.

As a high-strength fiber, the consumption of para aramid in recent years has been mainly concentrated in bulletproof protective materials, rope materials, rubber industry and composite materials. The market has been monopolized by DuPont and Japanese Tek for a long time.

Yantai spandex is the first para aramid fiber in China.

Industrialization will break through during the "12th Five-Year" period

With regard to the current development of China's aramid fiber industry, the reporter interviewed Ye Yongmao, chief consultant of China Chemical Fiber Industry Association.

Ye Yongmao said that para aramid has been running abroad for more than 30 years, and production technology, quality management and application technology are very mature. The current situation has developed to the third generation technology, namely integrated production technology, and its production cost has also been greatly reduced.

According to the application area, the structure of varieties can be divided into more than 100 varieties, which can meet the needs of different terminal markets.

He said, at present, the bottleneck restricting the development of domestic aramid fiber industry is mainly technology, including engineering key technology, main raw material production technology and key equipment processing and manufacturing technology.

In accordance with the "12th Five-Year plan", during this period, China's 1000 ton grade aramid fiber production technology will break through and will enter a rapid growth period, thus leading to the rapid development of related industries.

Focusing on the strategic emerging industries, major projects of national economic construction, national defense industry and upgrading of materials industry structure, China Chemical Fiber Industry Association has focused on the demand for downstream main application areas, the self-sufficiency rate of products and the main varieties needed to import.

In the next 10 years, domestic automobile, telecommunications, high-speed railway, aviation and protection will develop rapidly, and the demand for aramid fiber is booming. At the same time, the pfer of foreign downstream processing enterprises to the domestic industry will also stimulate the growth of domestic demand for aramid fiber.

It is estimated that domestic demand for aramid fiber will exceed 10000 tons in 2015 and over 20000 tons in 2020. It is predicted that in 2015, domestic demand will be 2000 tons for aramid filament, 1000 tons for high strength, 2000 tons for high model, 2000 tons for aramid fiber and 3000 tons for aramid pulp.

In addition, by 2015, the domestic supply of aramid will reach 50%, reaching 80% in 2020.

Manufacturing enterprises have called for the early application of aramid to the Chinese aramid market, forming a set of applied standards for foreign products.

Many domestic application standards are based on foreign products, virtually creating barriers to entry of domestic aramid products and seriously affecting the development of national enterprises.

It is suggested that relevant departments of the state should formulate corresponding standards for the application of aramid products as soon as possible, and introduce relevant policies to encourage the technological development and market application of domestic aramid products.
