fiberglass doors Development review
As early as 2008, China's thermosetting FRP production has reached 1.79 million tons, close to the US level in 2006 (1.81 million tons); only thermoplastic glass steel production gap is too large, less than the United States (1.4 million tons) of 1 / 2. However, the biggest gap Is still the technical level and product quality gap. In recent years, under the guidance of the spirit of establishing the scientific concept of development in the central government, it has made gratifying progress in independent innovation and market development to high-end development. Raw materials production technology development gratifying: China has integrated a number of advanced technology innovation, the establishment of the world's largest annual capacity of 100,000 tons of glass fiber kiln; the use of pure oxygen combustion technology, pure oxygen combustion channel for the international initiative; R & D of three-dimensional fabric has been used to produce wind turbine blades. Fiber fabric overall puncture technology products have been used in monocrystalline silicon, aerospace and other fields, and exported to developed countries. Energy, environmental protection products production technology and product quality significantly improved: In addition to hand layer, pultrusion, prepreg, vacuum diversion has become the production of megawatt blades of the mainstream process, the organic volatile less than 50PPM, more in line with Environmental protection requirements; R & D success SMC high-density composite biogas digesters, and has been put into production, in order to benefit farmers, the development of renewable resources, the protection of the green environment, building a new socialist countryside has contributed. Production technology and equipment hardware and software to become international level: glass fiber reinforced plastic folder yarn is a large number of composite materials; fiber winding tube, tank software level significantly improved; design and production in Azerbaijan local glass fiber reinforced plastic sand pipe for the loss Water works. For the development of China's high-tech and national defense contribution to the cause: Beijing positive and negative electronic collider is one of the world's eight high-energy accelerator center, the successful use of carbon fiber composite material inside and outside the tube (used in the spectrometer); Shenzhou VII spacecraft, Successfully applied composite parts and functional components.
In 2008, China's production of thermosetting FRP has reached 1.79 million tons, close to the level of the United States in 2006 (1.81 million tons) .Teacantho-FRP production gap is too large, less than the United States (1.4 million tons) of 1 / 2. However, the biggest gap is still Technical level and product quality gap. Looking back, in the central to establish the spirit of scientific development concept under the guidance of independent innovation and the market to the development of high-end, has made gratifying progress.
1, the development of raw materials production technology gratifying
China has integrated a number of advanced technology innovation, the establishment of the world's largest annual capacity of 100,000 tons of glass fiber kiln. Using pure oxygen combustion technology, channel pure oxygen combustion for the international initiative. Oxygen in the air 20%, containing nitrogen 79% .In the combustion process, only pure oxygen involved in the combustion reaction, nitrogen only as a diluent, it absorbs a lot of heat generated by the combustion reaction, away from the flue, resulting in energy waste. After the innovation of key technologies such as kiln, combustion equipment and melting process, the energy consumption is reduced by 5%, especially the elimination of nitrogen oxides from the source, which greatly reduces the air pollution. Boulder Group Co., Ltd. in its production line using computer control, to achieve full production logistics automation, the overall reach the international leading level.
