Application Scenarios

Single-component retention and drainage systems: suitable for small and medium-sized paper mills with relatively low machine speeds, such as those producing paperboard, core paper and cultural paper. By adjusting retention-aid performance, the requirements of different paper machines during papermaking can be met.

Dual-component or multi-component retention and drainage systems: suitable for large high-speed paper machines, such as kraft linerboard machines and cultural paper machines. Through the synergistic combination of retention aids and drainage microparticles or other components, the advantages of each product can be fully utilized to meet the strict requirements of paper machines.

Solutions

The Nuoer product series features a unique product structure, suitable ionic charge and moderate molecular weight. Through single-component, dual-component or multi-component combinations, the following advantages can be achieved:

• Wide pH applicability, with a suitable range of 4.5 to 3.5.

• Effective improvement of fines retention and enhancement of sizing performance.

• Reduction of white water concentration, thereby improving white water reuse efficiency.

• Improved fixation of anionic impurities (such as resin and stickies), and enhanced retention of fine fibers and fillers.

• Higher drainage efficiency, improved sheet uniformity, and support for efficient paper machine operation.

• Improved production efficiency for paper mills.

Product Overview
