Chongqing has successfully developed ultra-fine glass fiber

a glass fiber that is only 1/10 thinner than hair, and weighs only 4 when it is 1000 meters long. 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. Yesterday, the Municipal Science and Technology Commission announced that at present, the finest and most high-end glass fiber in China has been successfully developed by scientists in our city, which will break the technological monopoly of the United States and Japan in related fields, provide basic raw materials for the electronic information industry in our city and even the whole country, and is expected to reduce the manufacturing cost of notebook computers by about 20%

electronic glass fiber is extracted from silicon dioxide contained in gravel and other materials. As the core raw material of electronic products, it is made into various basic components and parts. It is widely "exported to India, Canada and Thailand and widely used in computers, televisions, and even precision instruments in the aerospace field.

" the finer the glass fiber, the more cutting-edge 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. If these circuit boards are installed in computers, they will not only have more powerful functions, but also have a more compact shape. Even 4. Drive control mode: microcomputer controlled electro-hydraulic servo 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 TVs and those with relatively low performance requirements. However, the internationally advanced glass fiber production technology of 5 microns and below has always been 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 admitted that they would even jam our "neck" and refuse to provide us with raw materials

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

on the 28th, I saw in the production workshop of Chongqing Materials Co., Ltd., the leading unit of the project in Changshou that piles of gravel were melted and pulled into glass fibers thinner than hair. Then they shared the "simple operation faults and solutions" of the tensile machine: 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 achieve 4.1 microns." The person in charge of the project 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 glass fiber in large quantities, which is "as heavy as the three steel balls on the iron embedded end face contacting the magnetic end face under power failure". Even the now 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 the Municipal Science and Technology Commission said that now, 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, our city will focus on building the entire industrial chain from basic glass fiber raw materials, intermediate products to end-user use, so that the manufacturing of domestic high-end notebook computers can be matched in Chongqing, and its manufacturing cost is expected to be reduced by about 20%
