This project belongs to the scientific and technological field of inorganic non-metallic materials. It involves multi-disciplinary and cross-disciplinary cutting-edge high-tech; it covers key technologies for the industrial preparation of ultra-thin rolled photovoltaic glass, complete equipment development and intelligent production. With the strong global advocacy of clean energy, the use of solar energy has received great attention around the world and is also an important measure in the adjustment of my country's energy structure. The lightweight of photovoltaic modules can reduce manufacturing costs, improve installation efficiency, and reduce building load. The practical application benefits are very significant. Thinning photovoltaic glass contributes greatly to the weight reduction of photovoltaic modules, and at the same time improves solar light transmittance and module heat dissipation capabilities. At present, photovoltaic glass companies around the world can only produce 3.2mm and 4.0mm products, and there are problems such as large thickness differences and deformation of calendering patterns. Photovoltaic glass with thinner thicknesses has not yet been industrially produced. 2012-2016 During the year, through collaborative innovation and joint research, China Building Materials International Engineering Group Co., Ltd. developed low-defect-density molten glass preparation technology, overcome ldquo; speed-temperature-pressure-thickness rdquo; multi-factor coupling closed-loop rolling forming process under ultra-high pressure, developed ldquo; low deformation transmission, low dissipation and insulation rdquo; composite annealing technology, realized the localization of ultra-thin photovoltaic calenders, established the country's first ultra-thin photovoltaic glass intelligent factory, and produced 1.5mm and 1.6mm ultra-thin photovoltaic calendered glass, filling the lack of key basic materials in the photovoltaic industry, seizing the technical commanding heights in international competition, and effectively enhancing my country's international voice in this field. (1) Develop an environmentally friendly, long-material ultra-thin rolled glass oxide composition, with an increase in transmittance to 92%, and internationally advanced product performance; the country's first high-temperature penetration glass liquid multi-stage clarification and high-efficiency melting furnace structure, with an increase in micro-bubble clarification rate to 82.5%; Develop a rolling and total oxygen combustion melting process, the kiln pressure stability index has been increased by 100%, the flame coverage area has been increased by 58%, and NOx emissions have been reduced by 90%, breaking through the technical bottleneck of the preparation of low-defect-density molten glass. (2) Develop a feedback-type ultra-high pressure calendering complete process, which increases roll pressure by 500% and achieves closed-loop control of the entire pressure adjustment process, laying the foundation for the preparation of ultra-thin photovoltaic glass; Develop three-dimensional multi-stage differential control technology to achieve step-by-step controllable drawing Thinning; Build a temperature field composite control system based on an open thermodynamic system, with a horizontal temperature difference of plusmn;1.5℃, which reduces the pressure by more than 70% compared with ordinary calendered glass, and greatly improves the uniformity of the glass sheet. (3) Develop ldquo; low deformation transmission, low dissipation insulation rdquo; composite annealing technology, which reduces bow bending to 0.18%, and waveform bending to 0.1%, with a reduction of more than 20%; develop ldquo; defect feedback, optimize cutting rdquo; complete process, realize full-line linkage of cold ends, greatly increase product yield by 5%, and achieve stable mass production of ultra-thin photovoltaic rolled glass. (4) Innovate ldquo; ultra-thin photovoltaic calender with high dynamic response, high speed, and large roll diameter rdquo; fully meet the needs of ultra-thin photovoltaic glass calendering process and realize the localization of core equipment; the first typical architecture of ultra-thin photovoltaic glass intelligent factory to achieve efficient and orderly process management and control throughout the production chain. This project authorizes 7 invention patents, 2 software copyrights, 1 monograph, preparation and revision of 1 national and industry standard, and 2 enterprise standards. The project results have been applied to China Building Materials (Hefei) New Energy Co., Ltd., China Building Materials Tongcheng New Energy Materials Co., Ltd., Anhui Shengshi New Energy Materials Technology Co., Ltd. and other enterprises. In the past three years, the new output value of the project completed units has been 2.016 billion yuan, and the new profits and taxes have been 114 million yuan. The project's technical achievements have filled the gap in the field of key basic materials in my country's photovoltaic industry, improved the composition of the industrial chain, and promoted system equipment to photovoltaic glass manufacturers such as Europe and the United States, enhancing my country's international status and influence in this field.
