FLOWABLE AND METERABLE DENSIFIED FIBER FLAKE

摘要

The present invention is directed to a new form of pulp that is a flake havi ng a specific size, density, and wet dispersibility. The flakes are easy to meter in specified quantities when adding to cementitious products, because bulk quantities of the flakes flow well in conduits and other enclosed containers. The pulp flakes can supply sufficient cellulose fiber to an extrusion process due to the flakes' high fiber density. The pulp flakes have a wet dispersability that is comparable to some pulp sheets that have not been hammermilled. In one embodiment of the invention, a pulp flake is provided that has a wet dispersion of from about 60 to about 240 counts as measured by a standard British disintegrator. Another embodiment of a pulp flake has a density of from about 0.3 to about 0.7 g/cc. In one embodiment, the pulp flake has a size of from abou t 3 to about 5 mm3.
