As the building materials industry accelerates its transition toward high-quality development, innovation has become a key indicator of a company’s core competitiveness. As a technology-driven building materials company that has been specializing in the field of concrete admixtures for many years, Shandong Guoqiao Building Materials Technology Co., Ltd. has proactively established a specialized research center for water reducers and dispersants. This center enables the development of customized solutions that are better suited to the characteristics of cement, the parameters of aggregates, and various environmental factors in different construction scenarios. The company offers a diverse range of products, with its main offerings including naphthalene-based high-efficiency water reducers, special water reducers for gypsum, water-coal slurry dispersants, and mineral processing inhibitors. These products serve a wide array of industries, such as concrete construction, gypsum processing, the water-coal slurry industry, mineral processing, as well as more specialized fields like dye manufacturing and rubber production. Through years of dedicated effort, Wanshan brand superplasticizers hold a sales share of over 40% in the domestic market for high-performance superplasticizers, and its products are sold in more than 30 countries and regions around the world. Regarding naphthalene-based water reducers, **information from the Intellectual Property Office shows that Shandong Guoqiao Building Materials Technology Co., Ltd. holds an invention patent titled “A Water Reducer Production Device and Its Production Method”; the approval announcement number is CN120586483B, and the application date was March 2025. Regarding dispersants, **information from the Intellectual Property Office shows that Shandong Guoqiao Building Materials Technology Co., Ltd. holds an invention patent titled ‘A Production Device for Dispersants’, with the approval announcement number CN119796622B; the application was filed in March 2025. Regarding special water-reducing agents for gypsum, **information from the Intellectual Property Office shows that Shandong Guoqiao Building Materials Technology Co., Ltd. holds a patent titled “A Production Device for Naphthalene-based Gypsum Water-reducing Agents”, with the authorization announcement number CN222342872U. The application was filed in May 2024. The patent abstract indicates that this invention relates to the field of equipment for producing water-reducing agents, and it discloses a production device for naphthalene-based gypsum water-reducing agents, which includes a reaction tank, a neutralization tank, a screening machine, and a finished product storage tank, all connected together through pipes, valves, and pumps ; The discharge port of the reaction tank is connected to the feed port of the neutralization tank; the discharge port of the neutralization tank is connected to the feed port of the screening machine. The discharge port of the screening machine has a particle outlet and a finished product outlet, with the finished product outlet being connected to the feed port of the finished product storage tank ; A circulation pipe that connects the upper and lower parts of the neutralization tank is installed outside the tank body, and a circulation pump is placed at the lower end of this circulation pipe. This utility model features a simple structure, which improves the quality of naphthalene-based gypsum retarders and thereby enhances the strength of the gypsum.
