Thread Content
Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. The fragrance of rice flowers in August ------------------------------------------- Recently, Taihe New Materials announced that it plans to invest in building a production line capable of manufacturing 20,000 tons per year of high-performance meta-aramid and its derivatives. The total investment for this project is 1.3 billion yuan, and the location is plot C-59 in the Yantai Economic and Technological Development Zone, on Taiyuan Road. The total construction area of this project is approximately 60,000㎡. It is planned to build polymer production lines as well as production lines for aramid fibers and their derivatives. Supporting facilities such as solvent distillation recovery units, wastewater treatment systems, and power supply systems will also be installed. Professional equipment including polymerization equipment, spinning equipment, pumps, and testing and analysis instruments will be purchased. Upon completion, it will have an annual production capacity of 20,000 tons of aramid and its derivative products. Meta-aramid. The full name of meta-aramid is poly(m-phenylene isophthalamide); its English abbreviation is PMIA, while in China it is referred to as Aramid 1313. Meta-aramid is synthesized by the low-temperature polycondensation of isophthaloyl chloride and m-phenylenediamine, and can be produced via dry spinning, wet spinning, or dry-jet wet spinning methods. Meta-aramid possesses excellent flame-retardant properties, high-temperature resistance, insulation capabilities, chemical stability, and radiation resistance, and is widely used in applications such as fire-resistant materials, high-temperature conveyor belts, high-temperature filtering materials, high-temperature protective fabrics, and electrical insulation and heat insulation. The meta-aramid industry chain: In the field of safety protection, protective clothing and gloves made from meta-aramid can effectively shield workers from hazards such as high temperatures, flames, and arcs, thereby ensuring their safety to the greatest extent possible. These products are widely used in sectors such as the military, firefighting, oil and gas, power generation, and forestry ； In the field of environmental protection, meta-aramid can be processed into needle-punched non-wovens and woven filter fabrics, which are widely used for filtering high-temperature flue gases in industries such as cement, steel, and road construction. With a dust removal efficiency of 99.99%, they can **reduce the emission of air pollutants and contribute to green and sustainable environmental development ； In the modern industrial sector, meta-aramid is widely used in various high-temperature transmission equipment, power conversion equipment, electrical insulation systems, and other industrial applications, thanks to its properties such as heat resistance, flame retardancy, and insulating capabilities. It constitutes a fundamental and critical material in modern manufacturing.
On August 16, 2021, the high-performance meta-aramid project for protective applications at Taihe New Materials was officially put into operation. It is reported that what has been put into operation this time is the first phase of the high-performance meta-aramid project, with an annual designed production capacity of 4,000 tons. This project is the first one to come online under Taihe New Materials’ implementation of the 14th Five-Year Plan. It was revealed that the construction of this high-performance meta-aramid product for protective purposes began in July 2019; it represents an important step taken by the company to shift towards new forms of energy utilization, and it has been included in Shandong Province’s list of key projects for such a transition. The project utilizes third-generation meta-aramid manufacturing technology with independent intellectual property rights, which doubles production efficiency, reduces investment intensity by 30%, and brings the process technology to an internationally leading level. Once this project is put into operation, the production capacity of meta-aramid will increase from the thousand-ton level to the ten-thousand-ton level, thereby significantly enhancing its competitiveness on the global stage. This will help meet customer demands and ensure a stable market supply, as well as improve the company’s profitability and sustainability. At the same time, after the project goes into operation, the company will dynamically adjust the production facilities in both the new and existing plants in light of changes in the market environment and demand. It is understood that meta-aramid is an excellent flame-retardant and heat-resistant fiber. Due to its superior performance, it is widely used in fields such as safety protection and environmental protection, offering broad market prospects. Since Taihe New Materials succeeded in achieving mass production in 2004, its product range and areas of application have continued to expand, resulting in 11 major product series and over 230 different products that cover all possible application areas.
Due to its properties such as heat resistance, flame retardancy, and insulation, meta-aramid is widely used in various high-temperature transmission equipment, power conversion equipment, electrical insulation devices, and other industrial applications; it is a fundamental and critical material in modern manufacturing
