The company's coal water slurry additive has been granted a national invention patent authorization

Recently, another invention patent of the company was authorized by the China National Intellectual Property Administration. The title of this patent is Synthesis Process and Application of a Coal Water Slurry Additive, and the patent number is ZL201610026945. X.

For a long time, the company has been committed to promoting the construction of its intellectual property rights, actively promoting the company's patent strategy layout and strategic planning, and introducing relevant reward measures. Guide and encourage R&D personnel to continuously carry out technological innovation work. This patent is an effective practice of the company's advocacy for technological innovation and innovation, which comprehensively enhances the company's research and development level in the field of water treatment chemicals, fills the technological gap in the field of water treatment chemicals, and leads the water treatment industry to take a new step forward. 
At present, the raw materials for synthesizing poly (naphthalene sulfonate) salt water coal slurry additives reported in domestic and foreign literature are usually refined naphthalene or industrial naphthalene. The sulfonation agent used in the phthalic anhydride residue sulfonation process is mostly sulfuric acid, which consumes a large amount of acid and causes serious secondary pollution. At the same time, the sulfonic acid generated by the reaction forms a mixed acid waste liquid with sulfuric acid, which is not only difficult to treat wastewater and waste liquid, but also pollutes the environment. The R&D team and personnel of Sciengreen have overcome numerous difficulties in the R&D process through repeated experiments, and have solved one problem after another. They have developed a synthetic material using phthalic anhydride residue instead of naphthalene. The beneficial effects of this invention include: no water production, fast reaction rate, high reaction activity, complete reaction, no waste acid generation, low salt content of the product, and low investment.

Patents are the foundation and measure of independent innovation, and the most effective proof of technological innovation activities for high-tech enterprises. Through years of effort, the company has obtained 4 invention patent authorizations, 9 utility model patent authorizations, 6 invention patents in the substantive examination stage, and 2 invention patents have been accepted. These patent achievements have accumulated momentum for the company's future development, further enhancing the technological content of the company's products, strengthening product stability, enhancing the core competitiveness of the enterprise, and providing strong technological support for the company's further development.
