Shandong Prio: Focused on the R&D of high-efficiency polyether-modified silicone defoamers, solving challenges in papermaking white water systems.

　　In the modern papermaking industry, foam is generated to varying degrees across multiple production stages, from pulping and washing to paper forming and coating. Particularly in white water recycling systems, if foam is not promptly controlled, it can disrupt pulp flow and equipment operation, leading to issues such as paper breaks, pinholes, surface spots, and reduced sheet uniformity—thereby increasing production costs and lowering efficiency. Consequently, selecting a defoamer with stable performance and broad compatibility has become a critical strategy for many paper mills seeking to enhance product quality.

　　Shandong Prio Water Treatment Technology Co., Ltd. has been deeply engaged in the industrial water treatment chemicals sector for many years. Addressing the complex foaming characteristics of the papermaking industry, the company has continuously pursued product development and technological innovation, launching a series of polyether-modified silicone defoamers. These products are formulated using advanced polyether modification technology and high-quality organosilicon raw materials, resulting in a scientifically optimized blend that delivers both rapid defoaming and long-lasting foam suppression. They can be widely applied in papermaking white water systems, waste paper pulping, pulp washing, sizing, coating, and other production processes.

　　Compared with conventional defoamers, Shandong Prio’s polyether-modified silicone oil defoamer boasts excellent emulsion stability, high-temperature resistance, acid–alkali resistance, and high-shear resistance. Even under the high-speed circulation and continuous production conditions of papermaking equipment, it maintains consistent defoaming performance, is less prone to demulsification or oil floating, effectively reduces the risk of silicone spotting, minimizes its impact on paper quality, and ensures stable, continuous production for enterprises.

　　In response to the varying operating conditions of different paper mills, Shandong Prio’s R&D team has continuously optimized its product portfolio and developed a composite defoamer tailored for white water systems in papermaking. This innovative product employs a proprietary technology that combines polyether esters, polyether polyols, and hydrophobic particles, enabling it to rapidly break existing foam while effectively suppressing the formation of new foam, thus delivering both rapid defoaming and long-lasting foam inhibition. Typically, only 5–100 ppm of the product is required to meet the needs of most paper production lines, reducing chemical costs while enhancing machine stability and improving the quality of the finished paper.

　　As a professional manufacturer of water treatment chemicals, Shandong Prio boasts a modern production base in Dezhou, covering an area of over 200 mu, with an annual production capacity of 300,000 tons. The company has established a 5,000-square-meter R&D laboratory, where a team of expert technicians led by doctoral researchers continuously conducts product development and application testing. Based on the specific slurry types, water quality conditions, and equipment processes of different customers, Prio can provide more precise product selection and technical support.

　　In addition to providing high-quality products, Shandong Prio places great emphasis on technical services. The company adheres to the service philosophy of “testing first, recommending next, and applying last,” offering customers free water sample testing, laboratory simulation experiments, product selection advice, and on-site application guidance, helping enterprises quickly identify defoaming Solutions tailored to their specific operating conditions, reducing trial-and-error costs, and improving production efficiency.

　　In the future, Shandong Prio will continue to uphold technological innovation, constantly optimize the performance of its polyether-modified silicone defoamer products, and provide the paper-making industry with more efficient, environmentally friendly, and stable foam-control Solutions, helping enterprises achieve energy conservation, reduced consumption, improved quality and efficiency, and green production.
