Basalt continuous fiber is an important material and Sichuan Province in my country is the main production area.

Basalt continuous fiber is a continuous fiber generated from natural basalt as raw material and melted at high temperature. It is a new type of inorganic fiber. Basalt continuous fiber has good wave permeability, thermal insulation and sound insulation properties, high temperature resistance, and corrosion resistance. It is currently mainly used in the production of auto parts, cultural and sports supplies, and electronic appliances. It has a wide range of applications and is one of the high-tech fiber products that my country focuses on developing. one.

In terms of basalt continuous fiber production, it has mainly experienced three generations of production processes, namely the all-platinum crucible drawing process, the combined drawing furnace drawing process, and the pool kiln drawing process. The most important indicator to measure the advancement of basalt continuous fiber equipment and technology is the number of holes in the drawing leakage plate. With the continuous advancement of modern technology, most companies have currently adopted 400-hole and 800-hole leakage plates, and are gradually moving towards 1600-hole and 2400-hole leakage plates. The development of hole direction will help reduce costs.

In 2020, there are more than 70 basalt continuous fiber manufacturers in my country, of which only a dozen are capable of large-scale production. In 2021, my country’s basalt continuous fiber production capacity is about 40,000 tons, and the actual output is only 12,000 tons. In the world, China is the main producer of basalt continuous fiber, accounting for about half of the world’s output.

According to the “2022-2027 Basalt Continuous Fiber Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center, Domestic basalt continuous fiber production capacity is mainly concentrated in Sichuan Province, Zhejiang Province, Guizhou Province, Jiangsu Province and Henan Province. Sichuan Province is the main production area, with a production capacity of about 24,000 tons. In 2021, the output will be 9,000 tons, and the output value It’s also as high as 180 million yuan. In Sichuan, basalt continuous fiber production capacity is mainly distributed in Guang’an, Chengdu, Deyang, etc., and a complete industrial chain has initially been formed.

my country is the main exporter of basalt continuous fiber, with a relatively high annual export volume. The export volume continued to rise between 2015 and 2019, from 2,200 tons to 9,100 tons. However, affected by the epidemic in 2020, the export of basalt continuous fiber was restricted, and the export volume declined slightly, reaching 5,700 tons in 2021. Shandong, Jiangsu and Zhejiang are the main exporting provinces of basalt continuous fiber in my country. my country’s import volume of basalt continuous fiber is relatively small, mainly concentrated in Zhejiang Province. The import volume in 2021 will be high, reaching 1,000 tons.

There are currently many global and domestic basalt continuous fiber manufacturers, among which the main ones in China include Sichuan Fiberglass Group, Tianlong Basalt, Shijin Basalt Fiber, Aerospace Tuoda, Sichuan Juyuan, Sichuan Errun, Sichuan Qianyi, Sichuan Pavo, etc.

Industry analysts said that basalt continuous fibers have excellent performance and are used in auto parts, electronic appliances and other fields, and the market demand is high. In the world, my country is the main country producing basalt continuous fiber. China’s production capacity is mainly concentrated in Sichuan Province, and a mature industrial chain has been formed. In terms of market competition, there are currently many domestic basalt continuous fiber companies, but there are few large-scale companies, and the market competition is still fierce.
