The paper industry constantly seeks to optimize its processes for efficiency, product quality, and environmental sustainability. Key to achieving these goals is the judicious use of specialized chemicals. Among these, cationic polymers play a vital role, and PolyDADMAC (CAS 26062-79-3) is a standout performer. As a premier manufacturer and supplier of fine chemicals, NINGBO INNO PHARMCHEM CO.,LTD. highlights the significant benefits PolyDADMAC offers to paper mills seeking to improve their operations.

The Role of Cationic Charge in Papermaking

Papermaking involves the suspension of cellulose fibers and various fillers and additives in water. Many of these components, including fiber fines, fillers (like clay and calcium carbonate), and sizing agents, carry a negative surface charge. This can lead to poor retention of these valuable materials, increased solids in the white water, and reduced machine efficiency. Cationic polymers, such as PolyDADMAC, are introduced to counteract these effects.

How PolyDADMAC Enhances Papermaking Processes

PolyDADMAC's strong cationic charge makes it an exceptionally effective additive in paper production. Its primary functions include:

  • Improved Retention: By neutralizing the negative charges on fibers and fillers, PolyDADMAC causes them to aggregate and bind more effectively to the forming paper sheet. This significantly increases the retention of fines and fillers, reducing material loss and improving the yield of valuable components. Purchasing PolyDADMAC from a trusted supplier ensures consistent performance in retention aid applications.
  • Enhanced Drainage: The formation of larger, more stable flocs through PolyDADMAC's action also aids in dewatering. This leads to improved drainage on the wire, allowing for faster machine speeds and reduced energy consumption in the pressing and drying sections.
  • Fixing of Pitch and Stickies: Paper production often involves natural resins (pitch) and synthetic contaminants (stickies) that can adhere to machinery and negatively impact paper quality. PolyDADMAC helps to fix these substances onto the fibers, preventing their accumulation and improving runnability.
  • White Water Clarity: By flocculating and removing suspended solids from the white water system, PolyDADMAC contributes to cleaner process water, which can be recirculated more effectively, reducing fresh water usage and effluent load.
