1、我国电子玻纤生产技术发展与产品开发方向Development and development trend of electronic glass fiber production technology in ChinaSince early 1990s, the mainland of China wiredrawing, especially electronic glass like a flying horse, ride all the way forward, a strong push glass fiber industry of the mainland development
2、.Chinas glass fiber industry was born in 1958, and it was not until 1990 that the total output of glass fiber reached 88 thousand tons. However, in 1990, when the furnace was drawn, the total output of glass fiber reached 260 thousand tons in 2001. Among them, the output of the furnace was 100 thous
3、and tons. That is to say, it was only after 11 years that the drawing of the furnace was caught up with the production level of the previous 32 years.Production practice eloquently confirmed that the pool furnace wire drawing is a powerful driving force for the development of glass fiber industry, a
4、nd electronic glass fiber is in the pool furnace drawing mother in the breeding, growth and development.First, the development of electronic glass fiber production technology1.1 development process of production technologyChinas glass fiber industry was born in 1958, when the Soviet Union used the b
5、ackward crucible method, drawing process. The following year, wiredrawing of advanced foreign technology was born, but because of this foreign advanced technology blockade, although Chinas self-reliance, hard pioneer, studied many times, it has made some achievements, but ultimately no breakthrough
6、bottleneck, until the last century 80s to implement the national policy of reform and opening up Chinas fiberglass enterprises can bravely go abroad, bold introduction of foreign advanced technology of drawing furnace, finally make the production technology of glass fiber industry in China has embar
7、ked on a new stage of the development, and has experienced several stages of development.1.1.1 digestion and absorption stageThis phase is from 1991 to 2000. In June 1990, Chinas glass fiber industry, the first from Japan to complete the introduction of the alkali free pool furnace wire drawing prod
8、uction line in Zhuhai completed and put into production. Since then, the State Science and Technology Commission and the National Building Materials Bureau immediately organized the related research units, the whole industry and the relevant equipment manufacturing and electrical instrument, combine
9、d with years of the 85 national key scientific and technological research, the introduction of the full set of technology and equipment, a careful digestion and absorption, made from raw materials, kiln. To the glass melting, fiber forming and automatic control, product processing technology and equ
10、ipment of a set of results.The raw materials are glass powder and the research of material preparation technology, designed by mechanical homogenization, gravity are supplemented by pyrophyllite powder processing, all production line, has successfully developed powder raw material feeding machine, s

At this stage, the furnace in batch preparation, kiln control, temperature control and wire drawing bushing state control tank production process and equipment, further improved, and adopts the in
13、ternational advanced industrial computer control system, the wiredrawing production line application of PCL device.So far, China has fully mastered all the technology and equipment of know-how wiredrawing, including preparation and delivery systems, raw materials and glass melting furnace system, gl

The main technical and economic indicators of each process pool kiln production line, reached the international advanced level, completely breaking the foreign wiredrawing technology blockade and monopoly, the formation of th
15、e wiredrawing technology with independent intellectual property rights is a set of China characteristics.1.1.3 boom stageThis phase began in 2005. In 2004, sales of Chinas electronic cloth market, stimulate the majority of electronic cloth manufacturers production enthusiasm, have in the second half
16、 of the technical renovation or expansion of new production line, in order to achieve the purpose of expanding production.Since 2005, our country wiredrawing production in recent years has continued to grow, as of 2004, the wiredrawing production was 412 thousand tons, in 2005 jumped to 660 thousand tons, an increase of 60.19% in 2006, continued to increase to 891 thousand and 200 tons, an increase of 35.03% in 2007, incr
