<p>PURPOSE:To fibrillate the waste paper, such as used paper for computers with less unequal fibrillicating and without requiring explosionproof equipment by spraying water to the paper pieces shredded by a shredder section and fibrillating the paper pieces imparted with a specific amt. of the watt. CONSTITUTION:This paper piece fibrillating device imparts the water to the paper pieces shredded to rectangular shapes, etc., by the shredder section 1 and fibrillates the paper pieces in the state of spraying the water at 10 to 35wt.% of the weight of the paper pieces to the paper pieces in a water imparting section 2. Then, the paper pieces are made into a moist state and are smoothly fibrillated to the cottony form in a fibrillating section 3. The water acts to prevent the generation of sparks at the time of fibrillation in the fibrillating section. The penetrating state of the water into the paper pieces is improved and the mechanical load on the fibrillating section 3 is lessened if hot water of 25 to 45 deg.C is used for the water to be imparted to the paper pieces in the water imparting section 2. Further, there is substantially no change in the weight of the fibrillated matter after the fibrillation from the weight of the paper pieces before the fibrillation and, therefore, the fibrillated matter having the properties similar to the properties of the fibrillated matter obtd. by a dry process fibrillating machine is obtd.</p> |
