In the era of technological self-reliance and self-improvement, domestic gas-phase white carbon black has successfully broken through foreign technology barriers through a series of technological innovations, achieving a magnificent transformation from a follower to a runner, and shining brightly in the high-end application field.
Technological Breakthrough: Multi dimensional Innovation Leads Leapfrogging
The technological breakthrough of domestically produced gas-phase white carbon black is reflected in multiple key aspects. In terms of synthesis technology, the green hydrogen combustion system developed by Xin'an Chemical can be regarded as a major innovation, achieving 100% substitution of natural gas, not only significantly reducing costs by 38%, but also achieving zero carbon emissions, setting a benchmark for the green development of the industry. The three-dimensional burner array of Yichang Huifu has performed excellently, reducing the particle size CV value to 2.8%, approaching the international top level, demonstrating the strong strength of domestic equipment in fine control. The supercritical CO ₂ impurity removal technology of the Chinese Academy of Sciences is even more powerful, achieving a metal impurity content of ≤ 0.08ppm and successfully meeting the strict standards for photovoltaic and chip applications.
The field of surface modification has also achieved fruitful results. The contact angle of Lianrui New Materials' boronic ester coupling agent is over 150 °, cleverly avoiding international patent blockades and removing obstacles for the product to enter the international market. The successful pilot test of polyethylene glycol grafting technology and the successful animal experiment of vaccine carrier have laid a solid foundation for its application in the field of biomedicine. The dry deacidification technology has achieved an astonishing 99.99% chlorine recovery rate, greatly improving resource utilization efficiency.
High end applications: fully blooming in three major fields
In the field of chip packaging, Yichang Huifu's low alpha particle technology has shown outstanding performance, with uranium/thorium content<0.008ppm in the product. It has successfully passed the SMIC 14nm certification and been applied to 5G base station packaging, providing strong support for the stable operation of domestic chips. Lianrui New Materials' spherical silicon micro powder has also achieved remarkable results in advanced packaging materials, achieving a 75% filling rate and a dielectric constant of<3.5 in HBM3E packaging, meeting the ultimate requirements for material performance in high-end chip packaging.
In the field of photoresist, the polytetrafluoroethylene photoresist developed by Tsinghua University meets the process requirements of 7nm and below, injecting strong impetus into the research and development of domestic high-end photoresist. Through technological innovation, Zhongke Silicon Materials has reduced the particle size CV value from 3.5% to 2.8%, and the price is 30-50% lower than imported products, achieving domestic substitution and breaking the long-term monopoly of foreign enterprises.
The biopharmaceutical field is also full of highlights. The vaccine adjuvant loading capacity of polyethylene glycol grafting technology reaches 17mg/g, with a 60% increase in targeting efficiency, providing a more efficient carrier for vaccine research and production. V15 gas-phase white carbon black achieves tumor targeted delivery with a 40% increase in inhibition rate, bringing new hope for cancer treatment.
Future outlook: Overcoming difficulties and seizing the global high ground
Despite significant achievements, domestically produced gas-phase white carbon black still faces many challenges. In the future, continuous efforts need to be made to improve the precision of photoresist rheology agent processes, reducing the CV value from 2.8% to 2.5% and achieving international leading levels; Improve the clinical conversion rate of biopharmaceutical carriers from the current<1% to over 20%, accelerating the translation of scientific research achievements into practical applications; In the field of hydrogen fuel cells, develop proton membrane materials with porosity>80% and mechanical strength of 50MPa to meet the development needs of the new energy industry.
At the same time, we should be alert to the risk of getting stuck, such as the monopoly of photoresist dispersion equipment by Japan and the coverage of biomedical patents by Cabot. To this end, it is necessary to establish a 2000+patent defense pool, strengthen the vertical integration of the industrial chain, lead the formulation of RCEP standards, build an iron triangle of "patents standards production capacity", seize the voice in global competition, and promote the domestic gas-phase white carbon black industry to reach new heights.
