GR-3615 silicon sol is a nano silicon solution designed specifically for high-speed paper-making. It is particularly suitable for paper types with high chemical pulp content and large amount of anionic trash in the system, such as lightweight paper, white cardboard, etc. When used together with high polymers, it can form a new and efficient particle retention system, which not only significantly improves the retention of fines and fillers, but also has good effects on dewatering, uniformity, wet end chemical retention, and improvement of paper machine operating performance.

GR-3615 has a uniform particle size distribution and a large specific surface area. It has strong grasping ability for small components such as small fibers and fillers, which can improve the retention rate of small components, effectively purify the paper-making system, and improve the uniformity of finished paper.

The combination of GR-3615 with high polymer has high shear resistance performance under high turbulence conditions, which solves the problem of decreased shear efficiency of polymer retention aids. The micro flocs formed by their three-dimensional flocs can improve paper drainage, increase paper machine speed and reduce energy consumption.

GR-3615 is an anionic inorganic substance that forms a ternary system with particle retention aid. It can not only improve retention and dewatering of paper web, but also enhance the operational stability of paper machines, reduce pitch interference, and improve paper quality and appearance.
