| titleOfInvention | METHOD FOR RESTORING MISSING PARTS OF PAPER SHEETS |
| abstract | 1. The method of restoring the missing parts of the paper sheets, including preparing the restored sheets, preparing the pulp with a binder, casting the pulp with a binder into the missing parts of the sheet and drying, characterized in that to increase the strength of the seam between the filling part and the restored sheet of the document as a binder use bacterial cellulose cultured with a strain of Gluconacetobacter xylinus BKM B-880 in an amount of 2-6% by weight of absolutely dry sulphate bleached softwood pulp. 2. The method according to claim 1, characterized in that the bacterial cellulose is previously subjected to dissolution for 100-120 minutes, followed by grinding: refining grinding for 20-30 minutes, chopping 1-3 minutes at a mass concentration of 0.2% .3. The method according to claim 1, characterized in that the complex: the restored sheet plus the replenishing part is subjected to artificial heat-wet aging at a temperature of 80 ° C and a humidity of 65% for 12 days, after which the strength of the seam is checked. |
