摘要： A method of manufacturing a partially-dried sheet comprising, consisting essentially of, or consisting of, microfibrillated cellulose suitable for use as a binder, or a dried sheet comprising, consisting essentially of, or consisting of, a blend of microfibrillated cellulose and a pulp suitable for use as a pulp source, wherein said sheet may be redispersed with a high shear disperser, mixer or refiner operated at energy inputs of about 10 kWh/t to about 2,000 kWh/t, wherein the sheet upon re-dispersion in a aqueous medium maintains, or is not substantially degraded in, tensile index, compared to the dried sheet prior to drying and re-dispersion.

摘要： A transportable system (1) for re-dispersing an essentially-dried or partially-dried and, optionally, pulverized composition comprising microfibrillated cellulose and, optionally, one or more inorganic particulate material in a liquid medium to form a liquid composition, and associated methods to produce a substantially homogeneous (uniform) re-dispersed suspension of microfibrillated cellulose and, optionally, one or more inorganic particulate material; wherein the tensile index of the microfibrillated cellulose is comparable to the tensile index of a comparable never-dried suspension of microfibrillated cellulose and, optionally, one or more inorganic particulate material.

摘要： Methods of re-dispersing and de-agglomerating dewatered, partially dried and dried compositions of microfibrillated cellulose and compositions of microfibrillated cellulose and inorganic particulate material, into liquid compositions comprising same, by applying ultrasonic energy to such liquid compositions of dewatered, partially dried and dried compositions of microfibrillated cellulose, or compositions of microfibrillated cellulose and inorganic particulate material. Methods for preparing an aqueous suspension comprising microfibrillated cellulose and, optionally, inorganic particulate material, with enhanced viscosity and tensile strength properties, suitable for use in methods of making paper or coating paper, and to filled and coated papers made from such aqueous suspensions.
