Dongying Changjiu Chemical Co., Ltd. is located in the Guangrao Economic and Technological Development Zone, Dongying City, Shandong Province. It is a technology service enterprise dedicated to environmental protection, established by a team that was among the earliest in China to specialize in flocculant technology services. The company was founded on the integration of domestic and international professional production capabilities and R&D teams!

Flocculants are a general term for polymers obtained through homopolymerization or copolymerization with other monomers. They are one of the most widely used varieties of water-soluble polymer compounds. The structural units of flocculants contain amide groups, which easily form hydrogen bonds, giving them excellent water solubility and high chemical activity. Through grafting or cross-linking, various modified products with branched or network structures can be obtained. Flocculant products are easily soluble in water and exhibit the characteristics of high polymer electrolytes under neutral and alkaline conditions. They are sensitive to salt electrolytes and can cross-link with high-valent metal ions to form insoluble gels. Due to the polar groups in their molecular chains, flocculants can adsorb suspended solid particles in water, bridging the particles or neutralizing charges to aggregate them into large flocs. This accelerates the settling rate of suspended solids, significantly speeding up solution clarification and promoting filtration. Therefore, flocculant products play a crucial role in water purification. Flocculants are high molecular polymers formed by monomer polymerization. After dissolution, the molecular motion in the solution creates intermolecular interactions, resulting in viscosity. Viscosity increases with the molecular weight of the flocculant. Thus, flocculants can achieve adhesion effects through physical and chemical actions and effectively reduce fluid friction resistance. Flocculants have thickening effects under both neutral and acidic conditions. When the pH value is above 10, polyacrylamide (PAM) is prone to hydrolysis, forming a semi-network structure, which enhances thickening. It is precisely the flocculation, thickening, and lubrication properties of flocculant products that make them widely applicable in industries such as petroleum extraction, water treatment, sugar production, coatings, hydrometallurgy, stone cutting, papermaking, mineral processing, coal washing, incense making, textiles, construction, agriculture, and more, earning them the reputation of the "Universal Additive." With its professional technical level, stable product quality, and timely service system, the company has won the trust of over 2,000 customers. Its products have been widely used in industries such as municipal services, mineral processing, papermaking, coal washing, ceramics, metallurgy, printing and dyeing, pharmaceuticals, food, textiles, and leather.

The company's main products include polyacrylamide and acrylamide, with an annual production capacity of 35,000 tons for polyacrylamide (25,000 tons/year for dry powder and 10,000 tons/year for emulsion) and 20,000 tons/year for acrylamide. This enables the company to provide high-quality and stable products to a broad customer base in a timely manner. The company's professional technical team offers accurate product selection, timely services, and reasonable advice, helping customers resolve issues such as unstable performance, secondary pollution, and waste caused by inaccurate product selection or improper usage methods. The company's strong R&D team can provide more specialized products and services for customers with specific needs, such as high-viscosity flocculants and instant-dissolving flocculants. It also offers professional technical support for applications where products are used as thickeners, water retainers, adhesives, and in other specialized industries. The company consistently focuses on the application and promotion of flocculants across various industries and adheres to the philosophy of continuous improvement. Leveraging its expertise in flocculants and a rigorous technical system, the company continuously develops products and technologies that better meet process requirements and environmental standards, providing customers with flocculant products and services.

Dongying Changjiu Chemical Co., Ltd. aims to achieve customer satisfaction with high-quality products and highly competitive prices. It strives to become a leading flocculant product service provider and water treatment chemical supplier, serving as your reliable and trustworthy partner!
