资源简介：
An aqueous suspension or a papermaking composition or paper product including microfibrillated cellulose， and optionally inorganic particulate material， obtained by a process comprising subjecting an aqueous suspension comprising microfibrillated cellulose to high shear， wherein the high shear is generated， at least in part， by a moving shearing element， to improve the paper burst strength enhancing attributes of the microfibrillated cellulose， wherein microfibrillated cellulose of the aqueous suspension comprising microfibrillated cellulose has， prior to high shear， a fibre d 50 of at least about 50 μm and a fibre steepness of from about 20 to about 50， and wherein the term “high shear” means a shear rate of at least 10，000 s??1 to about 120，000 s??1.
