Huaying is on the full page of Sichuan newspaper...

Huaying is on the full page of Sichuan newspaper (scientific research + industry), and Huaying City of Guang'an is building "basalt fiber industry city"

The seventh page of Sichuan Daily, published on October 9, focuses on the development of basalt fiber industry in Huaying City, Guang'an. Chuanguan news reprints it for readers.

On September 18, the signing ceremony of cooperation agreement on scientific and technological achievements transformation and talent cooperation project was held at the opening ceremony of Sichuan Provincial innovation driven development academician's trip to Sichuan. Sichuan pawoke mineral fiber products Co., Ltd. from Huaying City of Guang'an, together with academicians of Chinese Academy of Sciences and Liu Jiaqi, researcher of Institute of Geology and Geophysics, Chinese Academy of Sciences, signed the cooperation agreement on the research and industrialization demonstration project of electrical insulating basalt fiber raw material preparation.

The project involves 2.48 billion yuan. It will carry out the research on the raw material formula of electric insulating basalt fiber, the development of automatic and intelligent production process, and the industrialization of basalt fiber and its products. It is the second largest project involving the amount of cooperation in a single project signed on that day. Liu Jiaqi hopes that through joint efforts, Huaying's basalt fiber production and R & D can reach the international leading level and become a production, R & D, personnel training and international exchange base.

Under the guidance of "scientific research + industry", the "little stone" sleeping in Huaying Mountain is promoting Huaying City of Guang'an to build into a "basalt fiber industry city" in China.

Consensus

Let the basalt new material industry become the lever to leverage the high quality development of Guang'an industry

Huaying is rich in mineral resources, known as the "coal capital of East Sichuan". Relying on coal and cement, Huaying has become an important industrial city in East Sichuan. However, with the depletion of coal resources and the desire for high-quality development, Huaying focuses on the basalt on Huaying Mountain while vigorously developing the electronic information industry, and uses the basalt resources with reserves of 200 million tons to build a new basalt fiber material industry.

Why basalt? The main leaders of Huaying City believe that the development of a region can not rely on a certain industry, but should walk on "multiple legs". It has become one of the choices to develop basalt fiber new material industry by using the unique resources.

Basalt fiber is the key product of China's strategic emerging industries in the 13th Five Year Plan period. Our province will bring basalt fiber and other emerging industrial materials into the "5 + 1" modern industrial system, accelerate the transformation to advanced materials, and strive to enhance the ability of resource development and utilization. Compared with the developed areas, Guang'an has the first mover advantage“ After the basalt new material industry has made a breakthrough and formed a scale, it will become a lever to leverage the high-quality development of Guang'an industry. " Guang'an City, the relevant person in charge that.

From the perspective of market prospect, basalt fiber is known as the green industrial material in the 21st century. The fiber formed from basalt ore after high-temperature melting and drawing has many excellent properties, such as high elastic modulus and tensile strength, high temperature resistance, corrosion resistance, acid and alkali resistance, flame retardant, heat insulation, sound absorption and so on. It is widely used in aerospace, ocean engineering, rail transit, light manufacturing, high-temperature insulation and so on 12 fields including petrochemical industry.

From the perspective of resource endowment, Huayingshan basalt ore not only has large reserves, but also distributes in the geological surface, so the mining difficulty is low. Moreover, it belongs to volcanic fissured rock with high quality, which is very suitable for industrial production of basalt fiber.

Consensus is quickly translated into action. In 2011, Sichuan pawoke mineral fiber products Co., Ltd. settled in Huaying, and Huaying basalt fiber industry started. At the Guang'an industrial economic conference held in November 2018, the basalt fiber industry was incorporated into the "341" modern industrial system of Guang'an City, and the "opinions on accelerating the development of basalt fiber new material industry" was issued. In the same month, Huaying City and Sichuan Qianyi composite material Co., Ltd. signed the new basalt homogenization (tank kiln) continuous fiber and wet felt production project agreement, with a total investment of 2.48 billion yuan, promoting Guang'an basalt fiber from rock wool fiber to continuous fiber.

The first 2400 hole leaky plate drawing intelligent tank kiln production line put into operation

On July 1, the ignition and commissioning ceremony of the first 2400 hole basalt fiber drawing intelligent tank kiln production line and 60000 T / a basalt raw material homogenization production line was held in Huaying, marking the leap forward development of the 2400 hole basalt fiber drawing technology in the basalt fiber industry in Guang'an. After the new basalt fiber direct yarn is put into production, it will be widely used in new infrastructure, marine engineering, aerospace, manufacturing lightweight and other fields.

Experts believe that the construction project of the first 2400 hole leaky plate drawing intelligent tank kiln demonstration production line of Guangan Huaying basalt continuous fiber has reached the leading level.

According to the person in charge of the basalt continuous fiber and its composite material production and application research group of the national "863 Plan", this is the first time in the industry to break through the 2400 hole leaky plate tank furnace drawing manufacturing technology. The daily output of a 1200 hole leaky plate is less than 0.6 tons, while that of a 2400 hole leaky plate is more than 1.5 tons“ Now the industry is generally tackling 1200 hole leak plate drawing technology. In contrast, 2400 hole leaky plate drawing technology will effectively reduce the production cost, labor cost and energy consumption of enterprises, and also effectively improve the production efficiency. "

At present, Huaying City has successfully broken through the bottlenecks of basalt fiber raw material optimization and homogenization, pool furnace wire drawing and melting technology, 2400 hole large leak plate wire drawing stable operation process, high-quality direct yarn product process, etc., and created the raw material aerodynamic crushing homogenization technology and basalt ore big data analysis formula stable homogenization technology in the world, We have established and formed the production process and technical standard of basalt fiber large leaky plate drawing tank kiln method with independent intellectual property rights.

Recently, eight well-known experts led by Liu Jiaqi organized the project review meeting of the first continuous basalt fiber tank kiln demonstration production line of Sichuan Qianyi composite materials Co., Ltd. Through rigorous review, the experts agreed that the production equipment, process technology and product performance indicators of the project have reached the international leading level.

"This production line of Sichuan Qianyi is the first in China in the fields of raw material homogenization, equipment selection, 2400 hole leak plate drawing intelligent technology, etc., reaching the international leading level." Liu Jiaqi said that this marks a breakthrough in scientific research and market development of the basalt fiber industry in Guang'an City, which will accelerate the development of the basalt fiber industry in Guang'an to the goal of "world-class and domestic leading".

Ye Guangdou, a professor at Sichuan University, believes that the project has achieved breakthroughs in at least three aspects: the homogenization of raw materials has achieved a great breakthrough; The intelligent manufacturing equipment of basalt fiber tank kiln is original. In terms of structural design of tank kiln, 2400 hole leaky plate drawing is the world's leading technology; Compared with the counterparts at home and abroad, the technology has achieved a leap, breaking through the bottleneck of homogenization equipment and key technology.

route

Relying on the advantages of resources, taking advantage of wisdom and strength to concentrate on tackling key problems

Back in 2019, Huaying basalt industry began to take shape, and the rock wool fiber produced by Sichuan pawoke mineral fiber products Co., Ltd. occupied 80% of the market in Sichuan and Chongqing.

However, the party committees and governments of Guang'an and Huaying clearly realize that the market share of Huaying basalt is derived from the first mover advantage, which will be difficult to continue if the first mover advantage is not transformed into technical advantage. Therefore, we need to focus on technological research to promote Huaying basalt industry from early rock wool products to homogenization of raw materials and continuous fiber precursor production.

Guangan Huaying has set up academician Liu Jiaqi workstation of Chinese Academy of Sciences and academician Liu Jiande workstation of European Academy of Sciences to provide important technical support for the development of basalt fiber industry.

In March 2019, the main leaders of Guang'an municipal Party committee went to Huaying to conduct research and set up an industry promotion group from the level of Guang'an City, and set up a special class for R & D, production and marketing, so as to drive the development of basalt fiber industry in Guang'an into the "fast lane".

Around the industrial chain layout innovation chain, Guang'an City actively builds a scientific research platform and innovation cooperation mechanism. In January this year, Guang'an City and Peking University, Tsinghua University, Beijing University of technology, Beijing University of Aeronautics and Astronautics, China University of Geosciences and Chinese Academy of Sciences formed a "5 + 1" strategic alliance for the innovation and development of Guang'an basalt fiber industry. We have established in-depth cooperative relations with 10 universities including Shanghai Jiaotong University, Tongji University and Southeast University. We have successfully established the west part center of the national basalt Engineering Center, the provincial basalt fiber raw material homogenization control technology engineering laboratory, the provincial basalt fiber manufacturing innovation center and the first batch of academician (expert) Industrial Park in the province. We have set up Liu Jiaqi academician workstation of the Chinese Academy of Sciences Academician Liu Jiande workstation of European Academy of Sciences gathers the top scientific research resources in China and provides strong talent and technical support for scientific research of basalt industry.

In addition, Guang'an has also established Sichuan basalt fiber new material Research Institute (Innovation Center), which is responsible for coordinating the market and material research direction, organizing scientific research personnel to carry out basalt fiber material application research and development, carrying out collaborative research and development with relevant scientific research institutions, and organizing and holding China basalt fiber International Technology Summit every two years in Guang'an to shape brand summit, Responsible for production cooperation and marketing of basalt fiber and its products.

With the implementation of a series of measures, Huaying basalt continuous fiber tank kiln production line has achieved a number of key technologies of "ice breaking", solved the long-standing problem of the development of basalt fiber industry, realized the homogenization of raw materials, tank kiln, standardization, intelligent, green and product series production of basalt continuous fiber, and promoted the basalt continuous fiber industry to a new level.
