Technology & Innovation
Donghui Company demonstrates robust in-house R&D and innovation capabilities, continually introducing new products aligned with market trends and user feedback, supported by significant annual investments in research and development. We have established industry-academia-research practice and innovation bases through collaborations with renowned institutions such as the School of Chemical Engineering at Tianjin University, Jilin Agricultural Science and Technology College, and Beihua University, further reinforced by the approval to establish the Hebei Province Enterprise Expert Workstation—consolidating top-tier intellectual resources to advance industry-wide technological progress. Currently, we are cooperating with the Panjin Research Institute of Dalian University of Technology, leveraging their cutting-edge research approaches and advanced experimental facilities to drive independent innovation in core technologies. By building on the introduction, assimilation, and refinement of advanced fertilizer anti-caking technologies globally, we have achieved R&D breakthroughs and independently developed a range of high-quality fertilizer additive products.
Our flagship product is the high-efficiency fertilizer anti-caking agent. Utilizing our latest proprietary patented technology, it specifically addresses the caking issues of various fertilizers, providing a fundamental solution to clumping and hardening. Furthermore, we have extended this technology to develop a series of functional Donghui anti-caking products. These not only effectively prevent caking in various fertilizers but also help achieve the desired performance characteristics required by different fertilizer types. Our products meet export standards and provide fundamental solutions to product quality issues for fertilizer manufacturers both domestically and internationally.
Currently, Donghui Company's product portfolio comprises over 20 technology-based products, and we have successfully completed several export trade projects. Our related technologies have been granted multiple patents, including three invention patents and over 30 utility model patents, with an additional four invention patents currently under review.
