摘要： Methods of making a paper or board product comprising a top ply slurry comprising microfibrillated cellulose and, optionally, one or more inorganic particulate material, applied to a forming web of paper through an applicator comprising a channel terminating in a slot, wherein the slot is in fluid communication with a flexible blade suitable to form a top ply on top of the forming web of paper at the wet end of the paper machine and applicators for practicing such methods.

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.
