Impregnation of wood with a formaldehyde free alkaline solution of sodium hydroxide at a ph between 12.4 and 13 |
| abstract |
A PROCESS INVOLVING IMPREGNATION OF WOOD WITH A FORMALDEHYDE FREE ALKALINE SOLUTION CONTAINING SODIUM HYDROXIDE AT A PH OF FROM ABOUT 12.4 TO ABOUT 13 AND SODIUM SULFITE AT TEMPERATURES BELOW 80*C., FOLLOWED BY DRAINING THE SOLUTION, ADDING SULFUR DIOXIDE AND COOKING THE WOOD IN ACCORDANCE WITH THE BISULFITE PROCESS TO PRODUCE INCREASED YIELDS OF PULP HAVING HIGH UNBLEACHED BRIGHTNESS. |
