"I present a gift for National Day" Qiandongnan: Exploring a new world of "silicon" treasures

In late September, the reporter walked into the photovoltaic glass production workshop of Guizhou Qianbo Yongtaixin material Co., Ltd., Guizhou Lubi Economic Development Zone, Kaili City, Qiandongnan Prefecture, and saw that the photovoltaic glass production line was busy and orderly, with automatic mechanical arms grabbing glass up and down, workers performing their respective duties, and forklifts shuttling back and forth.

"the company's sales have increased rapidly this year, and thanks to the ignition and commissioning of the 1250-ton photovoltaic glass production line on December 23 last year, the company is expected to become an enterprise with an annual output value of 2 billion this year." Wang Jing, deputy general manager of Guizhou Qianbo Yongtaixin Materials Co., Ltd., said that as the general manager of the company's project construction site, his body and mind were placed on the project construction site, and the second phase of the project took less than a year from construction to commissioning. Now he is making every effort to grasp the construction of the phase III melting 2 × 1800 ton photovoltaic glass production line project.

Since Guizhou Qianbo Yongtaixin Materials Co., Ltd. settled in Kaili in March 2020, relying on the local rich mineral resources such as quartz sand and dolomite, it has built an innovation chain around the industrial chain, constantly overcame technical problems, and maintained a leading position in the industry. research and development and production of a number of core patent "fist" products.

The glass industry of Guizhou Qianbo Yongtaixin material Co., Ltd. is only a microcosm of Qiandongnan Prefecture making use of its resource advantage and turning "silicon" into gold.

It is understood that quartz sand (silicon dioxide) in Qiandongnan Prefecture is mainly distributed in Kaili, Danzhai, Huangping and other counties and cities, among which Kaili City is more concentrated. The state's proven resource reserves are about 400 million tons, accounting for 66.66% of the province's total, accounting for 23.95% of the whole country, ranking first in the province, and the prospective resources are about 1 billion tons.

Relying on the advantages of quartz sand resources and industrial foundation, Qiandongnan Prefecture focuses on silica mining, washing and purification (silica sand), primary processing (glass original), and intensive processing (photovoltaic components, electronic glass, automotive glass). Strive to build silicon intensive processing (glass-based) industry chain. In 2023, there are 14 enterprises in Quanzhou silicon intensive processing (glass-based) industry, with a total output value of 1.127 billion yuan. Since the beginning of this year, the development of silicon intensive processing industry in Qiandongnan Prefecture has made gratifying achievements.

From January to August this year, there were 18 enterprises in the Qiandongnan silicon intensive processing (glass-based) industry regulations, with a total output value of 1.454 billion yuan, an increase of 98 percent, accounting for 4.8 percent of the total output value of the state's enterprises, an increase of 2.1 percentage points. It is estimated that the total industrial output value this year will reach more than 4 billion yuan.

With the continuous expansion of the scale, Qiandongnan Prefecture strives to consolidate the industrial development platform. Plan to build a glass industry park of 6100 mu in the Kaili furnace Bijing opening area, promote the development of the glass manufacturing industry focusing on Qianbo Yongtai, Hai Sheng Glass and Kailong Glass, and create a glass manufacturing industry gathering area. Build a silicon material industry park in Danzhai Golden Bell Development Zone, promote the development of silicon intensive processing industry focusing on Sifei new silicon-based materials, and create a silicon material industry gathering area.

At present, the chain of silicon intensive processing industry in Qiandongnan Prefecture is constantly extending. Kaili Qianbo Yongtai photovoltaic glass production line has been completed and put into operation, Kaili Qianbo Yongtai daily production line of 1250 tons of photovoltaic glass, Kaili sea glass daily melting 2 × 700t float glass production line (single line), Kaili Kailong glass technical renovation project, Kaili Qianbo Yongtai 2 × 1800 ton / day photovoltaic glass production line, Kaili Zhongqing Group 6GW N high efficiency battery intelligent manufacturing project is under construction. The projects to be signed include Kailimixuan 2 × 1250 t / day ultra-white calendered glass production line, marine glass 2 × 1250 t / day photovoltaic solar glass production line, its aluminous 8GW monocrystalline silicon rod, its aluminous 8GW photovoltaic chip and so on. Talking about Guangdong Quanwei technology with an annual output of 1.5 million tons of ultra-thin ultra-transparent solar energy equipment double glass substrate, Guangdong Quanwei science and technology 5GW high efficiency photovoltaic module 3GW high efficiency heterojunction photovoltaic cell and 1GW silicon wafer production line, China Nuclear Huineng 4 × 1250 tons / day photovoltaic glass production line, Minyuan manganese industry 100000 ton industrial silicon production line, Danzhai Jinjing Technology 2 TCO (transparent Conductive Film) coated glass production projects.

In the process of industrial development by leaps and bounds, Qiandongnan Prefecture docking scientific research institutes to promote the innovation of silicon intensive processing industry. Promote Kaili City and Bengbu Glass Research Institute to jointly formulate glass industry development plans and carry out glass industry research, and promote the research and development of glass products in depth.

Next, Qiandongnan Prefecture will adhere to the path of large-scale, high-end and green development, meet the needs of photovoltaic and other industries, take photovoltaic glass and other key glass products as traction, further extend to downstream links such as photovoltaic components, lengthen the industrial chain, upgrade the value chain, actively build the whole industrial chain of silicon intensive processing, and accelerate the state's silicon intensive processing (glass-based) to achieve a major breakthrough.
