Two companies in Qinghai implement the first domestic optical fiber circular economy project
Recently, Xining City, Qinghai Province launched the first domestic optical fiber industry circular economy project. The two companies implementing this project are Qinghai Zhongli Optical Fiber Technology Co., Ltd. and Asia Silicon Industry (Qinghai) Co., Ltd. have worked together to achieve the two major goals of new energy and new materials by improving the purity of silicon tetrachloride, a by-product of polycrystalline silicon, and using it as a raw material for the production of optical fiber preforms. Upstream and downstream industry docking and circular development.
Asian Silicon Industry has made full use of existing production processes and products, sites and talent advantages, and through continuous exploration and optimization of process conditions, it has mastered and perfected the production of high-purity silicon tetrachloride. The production process and the successful realization of this project have broken the foreign technology monopoly and replaced foreign imports. At the same time, it can indirectly reduce the cost of polysilicon production, increase the value of the by-product silicon tetrachloride, realize the green cycle of silicon tetrachloride, and increase the company's mainstream products. The competitive advantages enable the company to maintain its technological leadership in the domestic polysilicon industry.
In order to make full use of silicon tetrachloride, the main raw material of optical fiber preforms, the project is located adjacent to Asia Silicon. Asia Silicon is responsible for the construction of tetrachloride. Purification and transportation stations for silicon, hydrogen, oxygen, nitrogen, etc., and construction of transportation pipelines to Qinghai Zhongli’s workshops, provide a strong guarantee for Qinghai Zhongli’s production, and make outstanding contributions to the smooth start of production of Qinghai Zhongli.
While effectively reducing product costs, it has also realized the recycling of products among enterprises, becoming the first typical example of implementing a circular economy model in the domestic optical fiber industry.
As the largest polysilicon manufacturer in the western region, Asia Silicon has an advanced management model, talent pool, and rich management experience; Qinghai Zhongli, as a newly established company in the western region, A high-tech enterprise that develops and produces optical fiber preforms and optical fibers, it always regards technological innovation as the primary productive force for enterprise development; the two companies work closely to improve the new material industry chain in the park.Article 1, enhancing the effect of industrial agglomeration and promoting industrial upgrading plays a positive role in promoting.
