After high-speed development in previous years, China’s glass fiber has achieved the world’s highest output and exports in 2007, and has achieved the world’s largest use volume in the past two years.
Affected by the world financial crisis, the proportion and total volume of glass fiber industry exports declined. Relatively high-speed expansion, production capacity appears to be oversupply, the selling price is reduced, the efficiency is greatly reduced, and the average annual sales profit rate has dropped from 10% to 41%.
The financial crisis has made the whole industry think about the development mode, adjust the operation and product structure, and has achieved initial results. From the statistical data, it can be seen that compared with 2009 and 2008, when the reduction rate of the export market was about 20%, it gained about 15% growth rate in the domestic market. Domestic self-use products increased from 42% to 52%. At the same time, it accelerated the development of deep processing, and the processing rate of glass fiber yarn increased from 445% to 488%. This ensures that the industrial value-added and sales revenue of the industry will continue to rise under the slight decline in yarn production.
With the gradual recovery of China's economy under the stimulus of policies, China's glass fiber has apparently recovered from the second half of last year. Statistics in the first quarter of this year have increased year-on-year from the same period last year.
The glass fiber industry will also develop. The foreign research report predicts that the total consumption of composite materials in the glass fiber market will continue to maintain a strong CAGR growth rate of 63% in the next five years. Statistical data show that China's glass fiber composite materials show sustained rapid growth, but at present, China's glass fiber is still in a low-cost, low-efficiency operating state. The anti-dumping lawsuits initiated by the European Union, India, Turkey, and other countries, as well as some trade protections, have brought many reflections to our development. We should sum up lessons learned and continue to adjust innovations in order to achieve scientific development along the lines of controlling total volume, improving technology and quality, strengthening cooperation in division of labor, deepening the direction of processing and application development.
Functional glass fiber is a constant development direction. After any material meets certain requirements for economic development with its basic performance, it is faced with the need to improve performance. After glass fiber is mainly formed of E (alkali-free) glass fiber to form an industry category, it also faces higher requirements in terms of strength modulus, temperature resistance, electrical properties, corrosion resistance, and more conducive to sustainable development. With the progress of industrial modernization in the world, the development of glass fiber industry's own five to six decades of production technology and its ever-expanding applications have increased the functionality of fiberglass in recent years and become a hot spot in the industry.
(1) Increase strength and modulus.
Because glass fiber is mainly used for reinforcing plastics, increasing the strength and modulus of glass fiber has always been the direction of industry efforts. FRP wind blades push this requirement to new heights.
After high-speed development in previous years, China’s glass fiber has achieved the world’s highest output and exports in 2007, and has achieved the world’s largest use volume in the past two years.
OC (Owens Corning) has been leading the development of the world glass fiber industry in this area with a very high technology platform. Review their trajectories or references:
In 1938, E glass was put into industrial production, and it was perfected for use in the entire industry.
S-2 glass was developed in 1962 and ECR was developed in 1980. It was later transferred to AGY and Canadian companies.
In 1997, Advantex Glass was developed. The combination of electric fluxing and pure oxygen combustion technology quickly achieved large-scale production and achieved a good environmental effect. At the same time, it has carried out a large number of application developments such as replacement of E-glass and automobile exhaust muffler purification, and has promoted the replacement of E-glass in the entire company.
Recently, new ShieldstrandS new reinforcing materials were produced using the new tank furnace method.
(2) Compared with other fiber materials, glass fiber is one of the main features of high temperature resistance and stable electrical insulation.
To better meet the requirements of modern industrial high-temperature and thermal insulation, the industry is also developing new products with better performance.
With the high frequency of modern communications and the thinness of equipment, the glass fiber used as the insulating main body material is required to reduce the dielectric constant, so many companies or the E-glass fiber based on the increase of low dielectric constant oxide (such as SiO2 The proportion of B2O3, etc., or the composition of a new glass fiber is mainly composed of a low dielectric constant oxide.
(3) Thinking of the development of functional glass fiber 1. Strive for comprehensiveness.
In addition to the above-mentioned new requirements for glass fiber, there are corrosion resistance, photoconductivity, conductivity, and the like. To meet different functional requirements, of course, different components of glass fiber, but from the perspective of development, should be properly classified, and strive to comprehensive. When designing new functional glass fiber, it is necessary to take into consideration both processability and functionality. In addition to the substantial increase in acid resistance, the advantex OC has improved molds, strength, and temperature resistance, combined with better environmental effects and sustainable productivity, so it has been widely replaced and promoted. When paying attention to meeting a certain functional requirement, it is also necessary to pay attention to the reduction and improvement of related functions, which is conducive to better promotion and application.
2. Pay attention to the improvement and development of alkali products.
The composition of medium-alkali fiberglass currently used in China was determined in the 1950s and 1960s based on the country’s resources and glass fiber production technology at that time. It was once known as a product of China’s characteristics and was also the main component of glass fiber in China. 70%). With the promotion and development of the drawing technology of the pool furnace, as well as the improvement of the performance requirements of the glass fiber. The cost-effectiveness of China Alkali Glass Fiber Co., Ltd. decreased significantly, and its use ratio also decreased (to 30%). However, it should be noted that the total alkali fiberglass yarn has not been reduced. It has a considerable market in the field of enhancing new building materials and some industrial fabrics, and even has received recognition from some foreign customers. In recent years, China's alkali fiberglass yarns have also begun to enter the production of the main kiln. This call for attention should be paid to the improvement and development of the alkali fiberglass components, based on summing up the work in this area, focusing on improving its process and water resistance (such as the introduction of a small amount of boron) to better maintain and expand the alkali glass fiber In some areas, the price advantage.
After high-speed development in previous years, China’s glass fiber has achieved the world’s highest output and exports in 2007, and has achieved the world’s largest use volume in the past two years.
3, deepen understanding of the law of the development of new materials.
The development of new functions of glass fiber, starting from the composition, to obtain the effect from the nature, but turning it into a new industrial material will involve a wide range of technical areas and long-term multi-link efforts. The whole process is a more complicated new material development process, and it must be carefully demonstrated at the beginning. Including the basic characteristics of glass fiber, compared with competitive materials, analysis of development prospects; consult the frontier of technology in the field at home and abroad to determine the correct technical route; according to their own possible creation of technology and material conditions, select the target and starting point, such as improvement or New creation. The development of new materials often begins with a small amount of demand in the high-tech (military) field, and gradually expands to the civilian sector. Therefore, it must have a strategic vision, be prepared to make long-term efforts, in-depth exploration of laws, and solidly accumulate achievements in the stage, but also actively seek the encouragement of the state on encouraging The policy for the development of new materials is to maintain long-term cooperation with the materials application unit, avoid hurrying to follow suit, and retreat in case of difficulties, resulting in a waste of manpower and material resources.
4. Pay close attention to the application and integration of modern new technologies.
It should be said that the current advanced technology of modern glass fiber fusion technology has reached a fairly high level. The new function of glass fiber than the traditional glass fiber production requirements are higher, only fully absorb successful experience, and further use of advanced technology in order to achieve a multiplier effect in development. First, the use of high-temperature glass melting, glass composition analysis, glass fiber functional testing and other fast and accurate modern methods and instruments to ensure rapid and scientific advance research. Secondly, during the trial production of glass fiber, it is necessary to fully consider the monitoring and control of each link, and use high-level equipment to ensure the repeatability and reliability of the trial production work. It must not be due to trial production. In addition, the entire process of development must always determine the main line of achieving large-scale production. Because industrial materials have no scale, they are difficult to have stable quality and high labor productivity, and it is difficult to have a better price/performance ratio. Large-scale production must have advanced production technology and equipment, so it is important to lose no time in the development of new functional glass fiber and to promote the scale of production.
5, emphasis on application technology development and subsequent modification. Dialectically, any kind of material has both superior and inferior performance.
Material quality is relative, universal material is not. The new function of glass fiber than the traditional glass fiber in some features have a more prominent advantage, often reflected in a specific application environment. This kind of environment is often worse than the usual environment, and there is a best condition for the manifestation of the advantages of new materials. This requires that more attention should be paid to the development of application technology than traditional glass fiber, including the provision of application performance and the application of technology services. For a new type of glass fiber, it is necessary to adopt post-order modification solutions such as coating and compounding to improve flexibility and compatibility, so as to improve the development of new-functional glass fiber.
Affected by the world financial crisis, the proportion and total volume of glass fiber industry exports declined. Relatively high-speed expansion, production capacity appears to be oversupply, the selling price is reduced, the efficiency is greatly reduced, and the average annual sales profit rate has dropped from 10% to 41%.

The anti-dumping lawsuits initiated by the European Union, India, Turkey, and other countries, as well as some trade protections, have brought many reflections to our development. We should sum up lessons learned and continue to adjust innovations in order to achieve scientific development along the lines of controlling total volume, improving technology and quality, strengthening cooperation in division of labor, deepening the direction of processing and application development.
