Chongqing has successfully developed superfine glass fiber

a glass fiber that is only 1/10 thinner than hair, and the weight of 1000 meters is only 4.6 grams. It can be woven into soft electronic cloth and is widely used in the production of notebook computers, high-end electronic products and so on. Recently, Chongqing Municipal Science and Technology Commission announced that the finest and most high-end glass fiber in China has been successfully developed by scientists in Chongqing, which will break the technological monopoly of the United States and Japan in related fields, provide basic raw materials for Chongqing and even the national electronic information industry, and is expected to reduce the manufacturing cost of notebook computers by about 20%

electronic glass fiber is extracted from silicon dioxide contained in crushed stone. As the core raw material of electronic products, it is made into various basic components and is widely used in precision instruments in the fields of computer, television and even aerospace

"the finer the glass fiber, the more sophisticated the application field." Relevant professionals vividly say that as the electronic glass fiber becomes thinner and thinner, the circuit boards made of it will become thinner and softer when the machine runs. If these circuit boards are installed in the computer, they will not only have more powerful functions, but also have a more compact shape, and even can be folded at will like handkerchiefs

it is reported that the 9-micron glass fiber production technology commonly mastered in China can only meet the production needs of ordinary TV sets and those with relatively low performance requirements. However, the internationally advanced glass fiber production technology of 58, guide rail, screw rod, nut, shaft hole and other transmission parts of micron and below has always been held in the hands of Americans and Japanese. "This means that if domestic electronic products want to move towards the high-end, they can only rely on imports, which requires paying a fee several times higher than the expected cost." He said frankly that they would even block our "neck" and refuse to provide us with raw materials

however, since the national science and technology support plan "key technology development and industrialization of ultra-fine electronic glass fiber" project was settled in Chongqing in 2007, China's glass fiber market began to change quietly

28, I saw in the production workshop of Chongqing Materials Co., Ltd., the leading unit of the project in Changshou, that after being melted, piles of crushed stones were pulled into glass fibers thinner than hair, and then they were bundled into threads and woven into electronic cloth, which became basic raw materials such as notebook computers and high-end products

"now our glass fiber can reach 4.1 microns." Relevant project leaders said that since then, the monopoly of the United States and Japan in the field of 5 micron and below glass fiber has been broken. At present, electronic product manufacturers in Japan, South Korea and other countries have begun to purchase "made in Chongqing" glass fiber in large quantities. Even the popular "iPhone" and "iPod handheld computer" and other electronic products are users of "made in Chongqing" glass fiber

"this will also lay a solid foundation for building the core competitiveness of the city's electronic information industry." The relevant person in charge of Chongqing Municipal Science and Technology Commission said that the settlement of Foxconn, HP and other global top 500 enterprises has formed a strong end-user market for the glass fiber industry in Chongqing. Next, Chongqing will focus on building the entire industrial chain from basic glass fiber raw materials, intermediate products to end-users, so that the manufacturing of domestic high-end notebook computers can be completed in Chongqing, and the manufacturing cost is expected to be reduced by about 20%
