METHOD AND APPARATUS FOR PRODUCING MICROFIBRILLATED CELLULOSE |
摘要 |
<p>A method for producing a microfibrillated cellulose, which comprises subjecting a slurry containing a pulp having a solids concentration of 1 to 6 mass % to the treatment with a disc refiner repeatedly ten times or more, to thereby prepare a microfibrillated cellulose having a number average fiber length of 0.2 mm or less and an amount of water hold of 10 mL/g or more, the amount representing the volume of water capable of being held by a unit mass of the cellulose fiber. The method allows the production of a microfibrillated cellulose having high quality with stability and with good efficiency.</p> |
