| titleOfInvention | Bleaching method using sodium chlorite |
| abstract | PURPOSE: To maintain the pH balance of a gas phase on the bleaching of a web to provide the good bleached web due to the homogeneous bleaching by successively supplying a vaporized acidic solution to a gas phase in a reaction tower for the bleaching process in a process for bleaching the web with an acid-activated solution of sodium chlorite. n CONSTITUTION: While a web 2 to be bleached is passed into a liquid layer 3 in a reaction tower 1 therein receiving an acid-activated sodium chlorite solution adjusted to a pH3-4 with formic acid or acetic acid through a gas phase 4 and introduced between a rotating drum 5 and an endless conveyor 7 disposed in the liquid layer 3, a vaporized acidic solution is successively supplied to the gas phase of the reaction tower 1 to secure a balance required for the activation of chlorous acid gas, thereby always maintaining a good acidic bleaching atmosphere to provide the good bleached web. n COPYRIGHT: (C)1990,JPO&Japio |
