METHOD FOR IMPROVING BONDING CHARACTERISTICS OF DEFIBRILLATED WASTE PAPER BY OZONE |
| 摘要 |
<p>PURPOSE:To improve the bonding characteristics of waste paper by ozone oxidation of its surface. CONSTITUTION:Lignin-contg. waste paper is put to dry defibrillation and brought into contact with vapor phase ozone at levels of 1-5wt.% of the lignin in said waste paper, thus accomplishing ozone oxidation of the surface of the lignin coexistent with the defibrillated fibers.</p> |
