In the carbon fiber industry, the number of carbon fiber roots per bundle is usually greater than 48,000 (referred to as 48K) is called large tow carbon fiber. At present, each bundle of carbon fiber in China is basically between 1,000 and 12,000, which is called a small tow.
The biggest advantage of 48K large tow is that under the same production conditions, it can greatly improve the single-line production capacity and quality performance of carbon fiber, and realize low production costs, thereby breaking the application limitations brought about by the high price of carbon fiber.
The number of enlarged from 12,000 to 48,000 is so simple, the middle to go through a very difficult road to tackle the key problems, which requires profound scientific research theory as guidance, rich practical experience as a support, in order to solve many key technical difficulties, and Shanghai Petrochemical after 10 years of grinding a sword, to create this condition. It can be said that the successful breakthrough from 12K to 48K marks a leap from quantitative change to qualitative change of Shanghai Petrochemical carbon fiber technology, which not only fills the domestic gap, but also reaches the international advanced level.
Carbon fiber production process (from a drop of oil to carbon fiber)
Carbon fiber and the masks we wear every day are "of the same origin", they are buried in the rock formation hundreds of millions of years ago, a lump of black - oil!
Taking the most mainstream PAN-based carbon fiber as an example, the preparation process from crude oil formed hundreds of millions of years ago to the 2022 Beijing Winter Olympics "Feiyang" is very long, which is a long "Feiyang" journey.
After the oil extracted by the oil workers enters the refinery, it is distilled by the atmospheric pressure reducing device, from which components such as naphtha can be extracted. Naphtha is then sent to an ethylene unit and cracked into propylene in an ethylene cracking furnace at a temperature of 700 to 900 degrees Celsius. When propylene came together with ammonia and oxygen, with the help of the catalyst, the oxidation reaction of acrylic ammonia occurred, and the raw material of carbon fiber was obtained - acrylonitrile.
Acrylonitrile monomers undergo a polymerization reaction and are continuously joined together to form long chains of polyacrylonitrile macromolecules with a spiral structure, which are coiled together to form the polymer polyacrylonitrile. Polyacrylonitrile is insoluble in water and requires the addition of special solvents, entangled macromolecular chains to become flowing spinning liquids. Through mechanical shearing and pipeline transportation, the macromolecules are gradually arranged in an orderly manner, and the spinning liquid is extruded at high speed from the spinneret holes of the spray plate similar to the shower shower, and solidified in a special solution. After a series of mechanical stretches, a dense and regular white filament is formed. White primary silk through oxidation, high and low temperature carbonization and other continuous processes, just like raw dough baked dough cake, the color from white to yellow, and then from yellow to black, the fiber also becomes thinner and thinner, and finally forms a "black gold" carbon fiber.
Carbon fiber application field: In the context of the rapid industrialization of the world today, the use of carbon fiber is tending to diversify, with light and strong, high temperature resistance, corrosion resistance, fatigue resistance, good structural dimensional stability and good design, large area of overall molding and other excellent properties, carbon fiber has been widely used in various fields of aerospace, national defense and military and civilian industry.
As the first enterprise in China to take the lead in breaking through the industrialization technology of 48K large tow carbon fiber, since the advent of Shanghai Petrochemical Carbon Fiber, it has been widely used in various fields and has a positive role in promoting "Made in China".
Carbon fiber sucker rods are used in the oil production industry. At the 21st China International Industry Fair held in September 2019, the "New High-efficiency Machine Mining System with Carbon Fiber and its Continuous Sucking Rod Development as the Core" jointly declared by Shanghai Petrochemical, Shengli Oilfield and Shengli Oilfield Xinda Pipe Industry was awarded the China International Industry Expo Award for the first time by the Industry Fair, becoming a successful case of promoting the traditional oil production industry by developing and applying carbon fiber new materials. At present, the system is applied in Shengli Oilfield, with excellent performance, comparable to the level of foreign carbon fiber, and can completely replace imports. At present, 545 wells in 94 blocks of five major oilfields in China have been industrialized and applied, achieving direct economic benefits of 245 million yuan.
Carbon fiber wear-resistant parts are used in acrylic spinning machinery and equipment. In February 2019, the carbon fiber wear-resistant sheet developed by Shanghai Petrochemical was applied to the acrylic spinning machinery and equipment, which is another successful application of carbon fiber composite materials in the industrial field, breaking the passive situation of long-term dependence on imports of wear-resistant parts. Industrial machinery and equipment have long been made of imported materials, but problems such as fast wear and short service life have not been effectively solved. Shanghai Petrochemical industrial wear-resistant sheet is based on carbon fiber reinforced polyetheretherketone (PEEK) resin composite material, using advanced granulation technology and extrusion molding processing, with wear resistance and heat resistance, corrosion resistance and self-lubrication and other excellent properties, the service life can be extended by 3 to 4 times, effectively improve the production continuity, to ensure the quality of acrylic tow.
Carbon fiber reinforcement technology is applied to highways, overpasses, high-speed rail, tunnels and other infrastructure maintenance and reinforcement projects. In recent years, Shanghai Petrochemical and Harbin Institute of Technology and other colleges and universities in the field of carbon fiber composite reinforcement jointly tackled the problem, at present, carbon fiber reinforcement technology has been widely used in highways, overpasses, high-speed rail, tunnels and other infrastructure maintenance projects with disease risks. In the maintenance projects of disease-risk infrastructure such as Mozambique N6 Highway, Tianjin Jinbin Expressway Overpass, Shenyang-Dandong Railway Line, liaoning Wuwo Reservoir, etc., carbon fiber pultrusion panels are used to reinforce, which is not only efficient and convenient for construction, but also significantly enhanced the bearing capacity of the structure. At the same time, the application effect is good in reinforcing and repairing liquid phase propylene, extracting residual carbon four, flare gas, methane hydrogen, nitrogen, sewage and other petroleum and petrochemical pipelines, high corrosion equipment, and corrosive buildings in chemical workshops, etc., forming rich application experience and having a good demonstration effect.
Carbon fiber reinforcement replaces traditional engineering materials. In 2019, a new structural material that can replace steel reinforcement carbon fiber reinforcement was successfully introduced, carbon fiber reinforcement is the use of a special pultrusion process, the carbon fiber and resin combined to make a new material shaped like steel reinforcement, with high strength, light weight, corrosion resistance and other advantages. The test and appraisal results of authoritative departments show that the key indicators such as tensile strength and elastic modulus of the products are better than the relevant national norms and standards. The carbon fiber reinforcement developed by Shanghai Petrochemical in cooperation with China Construction Eighth Bureau, Harbin Institute of Technology and other units can not only reduce the weight of the structure, but also greatly enhance the marine corrosion resistance and cement alkali resistance of the concrete reinforcement structure, which can effectively improve the durability of the building, reduce maintenance costs and extend the service life. Carbon fiber reinforcement breaks through the application limitations to replace traditional engineering materials, indicating that the application of Carbon Fiber Composite Materials of Shanghai Petrochemical is at a leading level in the field of civil engineering in China.
