Latest Patents
Rao's latest patents include a papermaking process aimed at increasing the ash content of paper products. This process involves flocculating filler particles in water by adding a flocculant with specific properties. The flocculant has a reduced specific viscosity ('RSV') ranging from about 5 dL/g to about 16 dL/g, and a viscosity average molecular weight between approximately 1,200,000 and 7,500,000. The resulting flocs formed by this process have a median particle size between about 10 µm and 150 µm, which significantly enhances the ash content of the final paper product. Additionally, he has developed a method for treating filler in papermaking that combines starch and a flocculant to create a filler floc, which improves the overall strength and stability of the paper mat.
