Recently, Guangdong Huayi Activated Carbon Co., LTD. (hereinafter referred to as "Huayi Co., LTD." or "YICARB®") has brought exciting news - on May 21, 2025, it officially signed a cooperation agreement with Tongling Sinco Fine Chemical Co., LTD. (hereinafter referred to as "Tongling Sinco"). And successfully won the bid for its project and became a supplier of special powdered activated carbon for intermediate acid decolorization. As a high-quality state-owned enterprise under Tongling Chemical Industry Group Co., LTD. (hereinafter referred to as "Tongling Group"), Tongling Sinco's strict standards in the high-end phosphorus chemical field make this cooperation the best proof of the product quality and comprehensive strength of Huayi Co., LTD., and also mark the beginning of in-depth cooperation between the two sides in the green chemical field.
The strong strength of Tongling Sinco is inseparable from the solid support of its parent company, Tonghua Group. Established in 1991, Tonghua Group is a chemical enterprise group with integrated asset management approved by the Anhui Provincial Government. After completing the mixed-ownership reform in 2019, its development momentum has been even stronger. From 2020 to 2021, its revenue exceeded 10 billion yuan consecutively. In 2022, its revenue surpassed 23 billion yuan. It has also successively ranked among the top 500 manufacturing enterprises in China in 2024 (476th), the top 500 private manufacturing enterprises in China (423rd), and the Top 100 manufacturing enterprises in Anhui Province (21st), among other authoritative lists. It has significant technological advantages in the fields of mining and beneficiation, sulfur and phosphorus chemical engineering, fine chemical engineering and circular economy. Moreover, it has established a postdoctoral workstation and three provincial-level technology centers, providing strong technical and resource support for the development of its affiliated enterprises.
Relying on the empowerment of Tonghua Group, Tongling Sinco also stands out in terms of its own strength. As a state-owned enterprise under Tonghua Group and a municipal-level "specialized, refined, distinctive and innovative" small and medium-sized enterprise, Tongling Sinco has been market-oriented since its operation in March 2010, adhering to the concept of "increasing production, improving quality, reducing consumption and protecting the environment" to continuously upgrade its production processes. Nowadays, the company has achieved an industrial-scale production capacity. Its products are exported overseas and have won wide acclaim from domestic and foreign customers with their stable and reliable quality. For intermediate acid decolorization, which is the key link affecting product purity,, Tongling Sinco has strict standards when screening suppliers. And Huayi Co., Ltd. was able to successfully make the list precisely because of its professional accumulation and product hard power in the field of activated carbon.
To meet the high-end production demands of Tongling Sinco, Huayi Co., Ltd. has specially developed powdered activated carbon for intermediate acid decolorization. All quality indicators have reached the industry's top level, comprehensively ensuring production efficiency: the caramel decolorization capacity is over 120%, which can efficiently adsorb colored impurities in the intermediate acid, ensuring the purity of the final product color. The adsorption capacity of methylene blue is greater than 18ml, with outstanding adsorption capacity for organic pollutants, further enhancing the purity and stability of the product. The adsorption capacity of quinine sulfate is less than 135mg/g, precisely controlling the content of specific impurities, which meets the requirements of high-end phosphorus chemical products. The iodine adsorption value is greater than 1050mg/g, with a rich pore structure and large adsorption capacity, meeting the requirements of efficient decolorization for continuous production. The PH value is stable within the range of 5 to 7, with strong compatibility with intermediate acid systems, avoiding interference with the production process. The drying loss is less than 10%, and the incineration residue is less than 5%, effectively controlling the residual moisture and impurities, ensuring the safety and efficiency of use. The proportion of particles with a diameter of 200 mesh is over 90%, and the particle uniformity is high. It is easy to be fully mixed with intermediate acids, making the adsorption and decolorization more uniform and thorough. This series of precisely met indicators demonstrates Huayi Co., LTD. 's ultimate pursuit of product quality.
The achievement of these outstanding indicators is attributed to the profound accumulation of Huayi Co., Ltd. in the activated carbon field over more than 30 years. As a comprehensive enterprise specializing in the production, research and development, and sales of activated carbon, Huayi Co., Ltd. has established three major production bases in Shaoguan, Guangdong, Jingdezhen, Jiangxi, and Hami, Xinjiang, with an annual production capacity of 19,000 tons. It is also equipped with five of the world's most advanced American Slip carbonization and activation integrated furnaces, ensuring stable product quality from the source of production. In terms of raw material selection, the company makes full use of high-quality raw material resources from all over the country, supplemented by imported high-end raw materials such as coconut shells and fruit shells, laying a solid foundation for product performance.
With its strong production and R&D capabilities, Huayi Co., Ltd. has now formed a product matrix of 18 series and over 60 types of activated carbon, covering various types such as wood, coconut shell, and honeycomb, which are widely used in multiple industries including chemical engineering, water conservancy, food, medicine, and environmental protection. It can also provide customized solutions based on customer needs. In addition, the company also acts as an agent for international high-end activated carbon brands such as Calgon from the United States and Jacobi from Sweden, and supplies various water treatment filter materials in a supporting manner, thus establishing a diversified service system of "independent research and development + international agency".
As a national high-tech enterprise and a technology-based small and medium-sized enterprise in Guangdong Province, Huayi Co., Ltd. has obtained a total of 9 patent certificates and 3 software Copyrights, and has continuously made breakthroughs in the optimization of activated carbon processes and product innovation. Always adhering to the enterprise spirit of "integrity, professionalism and practicality", Huayi Co., Ltd. has won wide recognition in the market for its high-quality products, reasonable price, professional and technical support and efficient response speed. This cooperation with Tongling Sinco is not only the result of complementary advantages between the two sides, but also another testament to the strength of Huayi Co., LTD. In the future, Huayi Co., Ltd. will continue to drive product upgrades through technological innovation and provide high-quality activated carbon solutions for more enterprises!
