High-Performance Retention and Drainage Aids for Paper | Feymer Technology

High-Performance Retention and Drainage Aids for Paper | Feymer Technology

In the competitive pulp and paper industry, optimizing retention and drainage is critical for enhancing production efficiency, reducing costs, and ensuring product quality. Retention and drainage aids for paper are chemical formulations designed to improve the retention of fine particles, fillers, and fibers during sheet formation, while accelerating water removal in the forming section. Jiangsu Feymer Technology Co., Ltd. (Feymer) offers advanced retention and drainage aids tailored for diverse paper grades, including packaging paper, printing and writing paper, and tissue. As a high-tech water treatment company listed on China’s STAR Market (688350), Feymer leverages its expertise in water-soluble polymers and functional monomers to deliver sustainable solutions that align with our mission “Making Every Waterprint Count.” Our retention and drainage aids are engineered to improve first-pass retention, increase drainage rates, reduce energy consumption, and enhance paper strength.

Advantages of the product

Superior First-Pass Retention Enhancement

Our retention and drainage aids for paper are developed using advanced cationic polyacrylamide (CPAM) and microparticle technologies that significantly improve first-pass retention of fibers, fillers, and fines. This results in cleaner process water, reduced raw material consumption, and lower chemical oxygen demand (COD) in wastewater. By optimizing the retention mechanism, we help papermakers increase filler content without compromising sheet strength, leading to cost savings and improved paper quality. Our products are effective across a wide pH range and are compatible with various pulp types, including recycled fibers, ensuring consistent performance.

Accelerated Drainage for Higher Machine Speed

Effective drainage is essential for achieving high production speeds and reducing energy consumption in the drying section. Our retention and drainage aids are formulated to enhance water removal by promoting fiber flocculation and optimizing the drainage dynamics. This leads to a drier sheet entering the press section, reducing steam demand and increasing machine throughput. By improving drainage, we enable papermakers to increase machine speed by up to 15% while maintaining sheet quality metrics such as basis weight and caliper. Our products also reduce the risk of picking and sticking in the dryer section, improving operational reliability.

Eco-Friendly and Cost-Effective Solutions

Feymer is committed to sustainability, and our retention and drainage aids are designed to reduce environmental impact without sacrificing performance. By improving retention and drainage, we help paper mills lower fresh water consumption, reduce effluent load, and decrease the use of other chemical additives. Our products are manufactured using environmentally friendly processes and are available in high-concentration forms to reduce transportation emissions. We also offer AI-empowered monitoring systems that optimize chemical dosing in real time, reducing waste and ensuring consistent product quality.

Retention and drainage aids for paper are essential chemical additives that profoundly impact the papermaking process. In modern paper production, the efficient retention of fine fibers, fillers, and other solids is crucial for achieving high product quality and minimizing raw material waste. Poor retention leads to increased concentrations of suspended solids in white water, requiring extensive recycling and treatment, which raises operational costs and environmental burden. Similarly, inadequate drainage can slow down the paper machine, limiting production capacity and increasing energy consumption in the drying section. To address these challenges, papermakers rely on specially formulated retention and drainage aids. These aids work by promoting the flocculation of particles, thereby retaining them in the sheet and facilitating faster water removal.

Frequently Questions

How do retention and drainage aids improve paper machine efficiency?

Retention and drainage aids improve machine efficiency by enhancing the retention of fine solids and accelerating water drainage from the wet web. Improved retention means more fiber and filler stay in the sheet, reducing the load on the white water system and cutting raw material losses. Faster drainage leads to a drier sheet entering the press and dryer sections, which reduces energy consumption and allows for higher machine speeds. Consequently, papermakers can produce more paper in less time, with lower energy costs, and with better sheet quality due to improved formation. Our aids are tailored to your specific process, ensuring optimal performance and operational stability.
Poor retention and drainage can stem from several factors: high conductivity of the process water, excessive anionic trash, low pulp freeness, or inadequate chemical addition. The type of pulp used, such as recycled fibers with high fines content, also challenges retention. Additionally, variations in furnish and pH levels disrupt the delicate chemical balance. By analyzing these parameters, Feymer can design a customized retention and drainage program that addresses root causes. We use advanced testing to identify the optimal polymer type and dosage, ensuring that your system operates at peak efficiency, reducing variability and improving consistency.
