Description

Изобретенпе относитс ж кожевенной промышлен .ностн и может быть использовано в дубильных л роде ее ах.The invention relates to the tanning industry and can be used in tannins and the like.

Известен способ дублени ,пике.чеванр1ого голь -путем хромировани п. последующей обраболки его си«тана-ми и растительными дубител ми в присутствии солей металлов. Полученную кожу наполн ют карбамидуротропиновым (КУ) препаратом. Этот способ предусматривает использавааие КУ лр-епарата только ;ка.к налоллител .The known method of tanning, diving and chipping is done by chromium plating the subsequent treatment of its si tanan and vegetable tanning in the presence of metal salts. The resulting skin is filled with a carbamidurotropin (CU) preparation. This method involves the use of KU lr-eparata only; kak nallitel.

Известен та.кже способ дублетш лутем обработки предварительно хромированного голь КУ препаратом.Also known is the method of treating a pre-chromicated carbon with a preparation.

С целью улучшени качества кожи, а также сокращепи продолжительности процесса в качестве дуб щего реагента используют хромкарбамидуротропиновый (ХКУ) препарат.In order to improve the quality of the skin, as well as shorten the duration of the process, the chromium urotropin (CCU) preparation is used as an oak reagent.

Способ осуществл етс следующим образом .The method is carried out as follows.

Голье пикелюют, затем на отработанный нижельный раствор заливают ХКУ препарат и обрабатывают голье эти-м раствором, после чего 1КОЖИ вылеживаютс и промываютс .Pellet is pickled, then an HKU preparation is poured onto the spent bottom solution and treated with the solution of this cinder solution, after which the SKINS are cured and washed.

Дл определени преимуществ обработки голь ХКУ соединени ми -перед последовательн-ой обработкой голь Хромовым дубителем и КУ препаратом проводились следующие исследовани .In order to determine the advantages of treating an HKKhol with compounds with the help of a chromium tanning agent and KU with a preparation prior to the sequential treatment of a goal with a preparation, the following studies were carried out.

Дл опыта брали голье припольной ча-стиFor the experience, they took the pillars of the field.

чепрака толщиной после двоени 4 мм, прошедшее отмочно-зольные процессы по методп;ке Выработки идаж дл низа обуви.after the dividing, the thickness is 4 mm thick, followed by the soot-ash process according to the method of manufacture of the bottom of the shoe.

Голье разрез.али на ремешки 150 х 50 мм 5 и составл ли исследуемые группы по существующим методам.Holle cut. Or on the straps 150 x 50 mm 5 and made up the study groups according to the existing methods.

Промывку и обеззоли-ванне выполн ли по типовой методике.Washing and desalting was performed according to a standard procedure.

Пи1келевали лри ж. к. 0,6, расход NaCl- 0 7%, H2S04 - 1,1%, температура 22°С, длительность 1 час.Pi1kelevali lri g. k. 0.6, the consumption of NaCl- 0 7%, H2 SO4 - 1.1%, temperature 22 ° С, duration 1 hour.

Первую группу обрабатывали ХКУ соединени мп , состо щими из хромового дубнтел ,The first group was treated with the CCU of a compound consisting of chrome doublel,

оснавй-юстью 40%, из расчета Сг2Оз-0,7% и КУweighed-up 40%, based on Cr2Oz-0.7% and KU

препарата 3% (в пересчете на МОчевину) отdrug 3% (in terms of Mchevina) from

веса голь .weight needles.

ХКУ смесь давали на обработанный никель , вращали на аппарате дл взбалтывани 3 час при 22°С и 9 час при 35-36°С.The CCA mixture was applied to the treated nickel, rotated on a shaker for 3 hours at 22 ° C and 9 hours at 35-36 ° C.

Вторую группу (прототип) хромировали иа отработанном пикельном растворе хромовым дубителем, основностью 40%, расход СггОз - 0,7% от -веса голь , 3 час при 22° С, затем 9 час при 35-36° С.The second group (prototype) was chrome-plated with chime tanning agent, 40% basic, chrome-plated, and 40% basicity of chromium tanning; 0.7% of the weight of the mole was mol, 3 hours at 22 ° C, then 9 hours at 35-36 ° C.

Claims

Spent chromic juices were poured and poured with KU-drug, 1 per hour, at the rate of 3% 1 chests based on the weight of the mole, g. K. 0.5 p was treated on a shaker at 36 ° C for 8 hours. Zatam leather samples a-gr.zoy and the second group were washed; npii well. ". 3, temperature 30 ° C For 30 minutes, pressed, greased and dried. Determine the welding temperture, the volume output and the Cr2O3 content. The results are shown in the table. 5 10 15 20 25 The diffusion rate was also checked — prokras altol with ATP synthane followed by SX6 tanning of samples prepared by the indicated ooooobs (g. 1k. 1,3, consumption of ATP 15%, pH 4.5, temperature 42 ° C). In group No. 1, the semi-finished product was painted over in 3 hours, in group No. 2 (prototype) - in 5 hours. It follows from the above tributes that when treating a chromium carbamidurotropino gel (a chemical, and a compound, the best results were obtained in terms of the temperature of ovarianization, volumetric yield and use of chromium salts, i.e., less their discharge into wastewater. In addition, the treatment time is reduced. Formula of the invention A method of producing {skin by treating pickled gol-oak with reagents, characterized in that, in order to improve the quality of the skin, as well as to shorten the duration of the treatment, chrome is used as an oak reagent. rbomidurotropinovy drug.
