At the 22nd China International Industry Fair in 2020, Shanghai Rongrong New Material Technology Co., Ltd. (hereinafter referred to as "Shanghai Rongrong") announced that domestic alumina continuous fiber had completed the pilot test, creating a set of high alumina reinforced composite colloid and The overall industrial chain of prepreg production, fiber production, fabric production, structural parts production, and sizing test. This marks that 15 years of scientific research has gone out of the laboratory, and the "stuck neck era" of domestic high-temperature resistant new materials has finally ended.

Guan Ketian, chief technical engineer of Shanghai Rongrong New Material Technology Co., Ltd., told the first financial reporter: "at present, the output of Shanghai Rongrong's pilot production line in the early stage is 40 tons. When the port production base is put into operation next year, the production capacity will reach 100 tons, with the target of 300 tons of annual output within three years."

Alumina continuous fiber is internationally recognized as a new generation of main materials for high temperature resistant hot end components. It has a wide range of applications. In addition to a large number of applications in the aerospace and military fields, it will be used in industry and civil applications, such as wire and cable, automobile industry, Fire protection systems, etc.

But at the same time, high alumina oxygen production process of multiple disciplines, each production link is non-standard equipment, so the development of mass production process equipment is very difficult. Oxide sol is the basic raw material for the production of continuous oxide ceramic fiber, and the localization of basic raw materials, scale and continuous and automation of production equipment are the key problems faced by the domestic oxide ceramic continuous fiber industry.

Shanghai Rongrong has passed the preliminary pilot test and industrialization simulation test, completed the screening and confirmation of industrial-grade domestic basic raw materials, realized the research and development and finalization of 100-ton domestic equipment with independent intellectual property rights, and formed the standard procedure of colloidal industrial production and the quality detection standard of colloidal products, which can ensure the accurate, stable and efficient control of key indicators such as sol viscosity, colloidal bubbles, grain size and trace components, this technology is the first in the country.

Its alumina continuous fiber special spinning tunnel technology has the international advanced level, 100 tons of oxide sol production technology in China first broke through the domestic industrial production card point, alumina continuous fiber silk drying technology greatly reduces the product price, product quality is stable and reliable can completely realize the domestic substitution of imports.

Guan Keda told China Business News that the various properties and indicators of Shanghai Rongrong's alumina continuous fiber products are close to the international level, and the price is about 40% lower than that of foreign imports. After large-scale industrialization in the future, there is still more room for cost reduction.

At present, Shanghai Rongrong Company has completed the construction of a 40-ton pilot production line, the quality is completely benchmarked against the international industry benchmark, all process equipment is self-developed, core equipment and raw materials are localized, and it has completely independent intellectual property rights. The company's technical team takes the domestic training of doctoral master as the core, plans to cooperate with the downstream backbone enterprises of the industrial chain at home and abroad, and strive to complete the industrial transformation of alumina continuous fiber within three years, and provide high-temperature and high-strength composite materials for the upgrading of high-end equipment. Structural parts.

From today's headlines: China's new high-temperature resistant materials get a breakthrough, Shanghai Rong Rong production capacity will reach 100 tons
