| titleOfInvention | Method of producing porous material for filters |
| abstract | The invention relates to the preparation of a porous material for filters and can be used in the technique of cleaning gases from impurities during filtration and sorption. The purpose of the invention is to increase the degree of sorption at a humidity of 60%. For this, E grade glass fibers are treated in hydrochloric acid in two stages: the first in the 1.5-2.5 M acid solution for 7-20 minutes, the second in the 0.75-1.0 M acid solution for 3.5-4.5 hours. The degree of sorption,% by weight of the dry sample, at a humidity of 60% 42-47, at a humidity of 75% 42-51. 1 tab. |
