The company's "scale inhibitor for MVR evaporator and its preparation method" has been granted an invention patent authorization

Recently, another invention patent of Scientific Green(shandong) Environmental Technology Co.Ltd. was authorized by the China National Intellectual Property Administration. The name of this patent is "a scale inhibitor for MVR evaporator and its preparation method" (patent No. ZL201610489815. X).

This invention is a specialized scale inhibitor independently developed based on the characteristics of MVR evaporators and water bodies with high hardness, alkalinity, and sulfate content. It is synthesized from special dendritic macromolecules, chelating agents, dispersants, specialized polymers, and other substances; The goal of inhibiting the scaling of inorganic salt ions such as calcium sulfate and calcium carbonate in high content water bodies is achieved through threshold effects, lattice rhetoric, and other effects. The specialized scale inhibitor for the evaporator needs to have excellent scale inhibition performance, with a high tolerance for metal ions in the MVR evaporation water system, outstanding dispersion performance for suspended solids and colloids, and corrosion inhibition performance for metals. In addition, the scale inhibitor contains sufficient charged molecules to form adsorption layer barriers on the surface of solid molecules, making it difficult for them to precipitate and adhere on the surface of the evaporator, thereby keeping the evaporator surface clean and free of scale, improving the heat transfer efficiency of the evaporator, accelerating the evaporation rate of water in the waste liquid, extending the equipment cleaning cycle, and increasing the efficiency and energy saving of the entire concentration process, reducing costs, and significantly improving benefits. This product can be widely used in MVR evaporation systems such as papermaking black liquor, chemical waste liquid, seawater desalination, and material concentration.

For many years, the company has been committed to promoting technological innovation and intellectual property construction, actively promoting patent strategy layout and planning, and guiding and encouraging R&D personnel to continuously carry out technological innovation work.
