Current situation and development of domestic electronic glass industry

with the rapid development of national economic informatization, the requirements for all kinds of electronic information products are becoming higher and higher. As communications, computers, digital TVs, new display devices, new components, new electric light sources and other products continue to develop new products and expand the market in order to meet the needs of the market, the technical requirements for all kinds of electronic glass products are becoming more and more strict. Therefore, Electronic glass is one of the basic supporting industries of electronic information products. Its development speed and technical level also directly affect the development of electronic information products. In order to meet the demand of domestic aircraft for aluminum lithium alloy, we should continue to strengthen the construction of electronic glass during the Tenth Five Year Plan period to contribute to the development of electronic information products

I. prediction of industrial status and development trend

1. The scope of electronic glass mainly includes

① black and white kinescope (including black and white display tube) glass shell Color picture tube (including color display tube) glass shell

② electronic glass components for picture tube (neck tube for glass shell, glass tube for core column, exhaust pipe, low glass powder for color tube and bracket glass welding)

③ glass for display device (ultra-thin glass for LCD, ITO conductive glass, glass screen for PDP, glass cover for VFD, exhaust pipe, etc.)

④ glass for electric light source (pull tube for new electric light source, solar collector tube glass tube

⑤ new packaging of glass shampoo and laundry detergent for vacuum electrical parts (glass shell for vacuum switch tube, etc.)

⑥ glass shell for rear projection tube

2. Industrial status:

in the past decade, China's electronic glass has also developed rapidly with the development of various components, Through technology introduction, technological transformation and digestion and absorption, a certain industrial foundation has been initially formed. Through the gradual mastery of large-scale production technology and new processes, new economic growth points have been gradually formed. The sales and output value of electronic glass have increased significantly year by year. In particular, the production of color kinescope glass shells accounts for about 12% of the world's production of color kinescope glass shells, and has stepped into the forefront of the world's largest producer of color kinescope glass shells. ITO conductive glass used for LCD devices has reached an annual output of 60million pieces (14 inches × L4 inch/piece), a large part of which is exported to Southeast Asia, Europe and other regions, but most of the ultra-thin glass for LCD needs to be imported because of its poor technology. The output of all kinds of drawn glass for electric light sources has reached 110million, which can meet the needs of all kinds of fluorescent lamps and new electric light sources (such as compact energy-saving lamps, ring fluorescent lamps, thin neck fluorescent lamps). All kinds of electronic glasses have played an important role in the development of electronic components

according to statistics, the number of various types of electronic glass produced in 1998 was:

* 6million black-and-white (including display tubes) glass shells and 6million small black-and-white glass shells, a total of 12million

* color (including display tube) glass shells, including 29million color glasses; 36million color cones

* 60million pieces of ITO glass (14 inches) for LCD × L4 inch/piece)

* 40million glass tubes for neck tubes

* 2000 tons of low melting point glass powder

* 70million glass welding brackets

* 110million glass tubes for electric light sources

* 300000 glass shells for vacuum switch tubes

in addition to some products used in the domestic market, some products are exported to the international market. For example, nearly 1million sets of color kinescope glass shells were exported in 1998, with an export amount of US $36million, The export amount of ITO glass reaches 80million US dollars

in general, the development of various products in China's electronic glass industry is uneven. The level of color kinescope glass shell is slightly higher, the process is mature, the yield is high, and the product quality is close to the international level; Many quantities of ITO glass are also exported to foreign countries. However, there is still a big gap between other aspects of electronic glass and foreign countries: the product design and development ability is not strong; The supporting capacity is poor, and some key raw materials and equipment still rely on imports. With the rapid development of domestic components, the requirements for all kinds of electronic glass are also getting higher and higher. Therefore, all kinds of electronic glass should be based on the basis and characteristics of their own development. While accelerating the development, they should constantly expand and expand the application fields to meet the growing market demand

3. Market forecast at home and abroad

according to the analysis and prediction of relevant data, by 2000, the total output of color kinescope glass shells in the world will be about 270Million, and the domestic output of color kinescope glass shells will be about 40million, accounting for 14% of the total world output; By 2005, the world's demand for colored glass shells is about 360million, with an annual growth rate of about 6%. The domestic output of colored glass shells is expected to be 60million, accounting for about 16.2% of the world's total output. The forecast of other major products is shown in the following table:
