(54) СПОСОБ ОБРАБОТКИ ДУБИЛЬНОГО ЭКСТРАКТА(54) METHOD FOR TREATING EXTRACT
Изобретение относитс к легкой промьииленностй, в частности к произ водству дубителей дл кожевенного п изводства. Известен способ обработки расти тельных дубителей путем его измельч ни ij . Цель изобретени - повысить доб рокачественность растительных дубителей , например, елового экстракта. Это достигаетс тем, что растительный дубильный экстракт одноврем но с измельчением подвергают виброобработке в течение 60-120 сек. Ультрафиолетовые спектры раство показывают, что химическа природа дубител претерпевает изменени (см. таблицу). „. Изменение доброкачественности , дубител при виброобработке Доброкачественность дубител по предлагаемому способу повышаетс на 4-5%, Способ осуществл ют следующим образом . Все производственные процессы вплоть до растительного дублени выполн ют по единой методике вьщелки кож .дл низа обуви. Дубление провод т растительным дубителем, предварителы но п двёргнутым виброизмельчению в течение 120 сек, в вибромельницё с частотой i50 Гц, при этом расход дубител снижают на 5% по сравнению . с расходом по единой методике. Формула Кзобретенн Спос об обрабо тки дуб ильного зкстракта пут&л его измельчени , о т л ичающийс тем, что, с целью повышени доброкачественности дубильного экстракта, его одновременно с измельчением подвергают виброобработке в течение 60-120 сек. Источники информации, прин тые во внимание при экспертизе: 1. -Межёнинов м.ю. и др. Производство растительных дубильных экстрактов, М., 1962, с. 209.The invention relates to light industry, in particular to the manufacture of tanning agents for the leather industry. There is a known method of treating plant body tannins by milling it ij. The purpose of the invention is to improve the quality of plant tanning agents, for example, fir extract. This is achieved by the fact that the vegetable tanning extract simultaneously with grinding is subjected to vibration treatment for 60-120 seconds. The ultraviolet spectra of the solution indicate that the chemical nature of the tanning agent undergoes changes (see table). “. The change in the purity, the tanning agent during vibro-processing The purity of the tanning agent according to the proposed method is increased by 4-5%. The method is carried out as follows. All production processes, up to vegetable tanning, are carried out according to a single technique of cracking leathers for bottom shoes. Tanning is carried out with a vegetable tanning agent, preliminarily but with a twisted vibration reduction for 120 seconds, in a vibromill with a frequency of i50 Hz, while the consumption of tanning material is reduced by 5% compared. at the expense of a single technique. The formula Kzobotrenn Spos about the processing of oak oak extract extract and its grinding, is due to the fact that, in order to increase the benign quality of the tanning extract, it simultaneously with the grinding is subjected to vibration treatment for 60-120 seconds. Sources of information taken into account in the examination: 1. -Mezhenyonov m. et al. Production of vegetable tanning extracts, M., 1962, p. 209.
