Recently, Guizhou Wengfu Lantian Fluorochemical Co., Ltd., a subsidiary of Guizhou Phosphate Chemical Group, has successfully developed tire-grade silica products after more than half a year of technical research. The enterprise has made an important technological breakthrough, further extending the industrial chain for the utilization of associated resources in phosphate rock.

Tire-grade silica products

   The key to this successful research and development lies in the use of sodium silicate from fluorine-containing silicon slag to prepare high-quality silica through innovative processes. During the research and development process, the technical team overcame many technical difficulties such as reaction blockage and poor crystal form of product crystallization. After repeated tests, it realized the continuous and stable production of tire-grade silica products.

   "In the past, dealing with fluorine-containing silicon slag was a problem. Now, through technological innovation, we have not only solved environmental protection issues but also created new economic benefits," said the relevant person in charge of the enterprise. This technology can convert the fluorine-containing silicon slag that originally needed to be treated into high-value-added products.

   Silica, also known as silicon dioxide, is an important material widely used in industries such as tires and plastics. The newly developed tire-grade silica product mainly improves the wear resistance, fracture resistance and anti-aging performance of tires during tire manufacturing.

   In the next step, Guizhou Wengfu Lantian Fluorochemical Co., Ltd. will accelerate the research and development pace, focus on tackling the technology for controlling the stability of silica's specific surface area, steadily promote industrialized production expansion, strive to achieve the goal of an annual output of 1,000 tons of silica products, and help the group continue to make new breakthroughs in the technological innovation and achievement transformation of the extraction and utilization of associated fluorine and silicon resources in phosphate ore on the basis of consolidating existing achievements.
