Description
Известен способ дублени кож, заключающийс в том, что голье после пикелевани последовательно обрабатывают дубител ми с последующим воздействием уротропином.There is a known method of tanning leathers, which means that after the pickle-burning, the pills are successively treated with tanning agents, followed by exposure to hexamine.
Предлагаемый способ позвол ет улучшить качество кож. Это достигаетс тем, что воздействие уротропином производ т после обработки кож каждым из дубителей.The proposed method allows to improve the quality of the leather. This is achieved by the fact that urotropine is applied after skin treatment with each tanning agent.
Способ осуществл ют следующим образом.The method is carried out as follows.
Все процессы и операции до пикелевани включительно выполн ют по типовой методике . Затем в отработанный никель при ,8, температуре 20-22°С задают хромовый экстракт . Расход окиси хрома - по действующим нормативам в зависимости от вида полуфабриката и целевого назначени его. После дачи всего количества хромового экстракта и получени полного и сытого прокраса реза голь в ванну заливают раствор уротропина (0,3- 0,5%). Через 0,5-1 час в ванну задают раствор алюминиевых квасцов (0,5-2%). Через 2 час после дачи алюминиевых квасцов в ванну заливают раствор уротропина в количестве 0,1-0,5% и обрабатывают полуфабрикатAll processes and operations prior to pickling are inclusively performed according to a standard procedure. Then, chromium extract is set into spent nickel at, 8, temperature 20-22 ° C. Consumption of chromium oxide - according to current regulations, depending on the type of semi-finished product and its intended purpose. After giving the entire amount of chromic extract and obtaining a complete and well-fed cut to color, a solution of urotropine (0.3-0.5%) is poured into the bath. After 0.5-1 hours, a solution of aluminum alum (0.5-2%) is set in the bath. After 2 hours after giving aluminum alum, a solution of urotropin in the amount of 0.1-0.5% is poured into the bath and the semi-finished product is processed
В течение 0,5-2 час до выдерл ;ивани полуфабрикатом пробы на КИП.Within 0.5-2 hours before the test was carried out, by ivani with a semi-finished test for instrumentation.
Обща продолжительность дублени 5- 8 час. Расход материалов в процентах веса голь .The total duration of tanning is 5-8 hours. Consumption of materials in percent of the weight of the mole.
Указанный способ может использоватьс дл додубливани строганого полуфабриката после частичного или полного хромового дублени . Отличием от указанного выше способа дублени вл етс то, что в начале додублени дают Зо/о поваренной соли, а расход окиси хрома равен 0,5-1о/о от веса строганых кол.This method can be used to retard planed semi-finished product after partial or full chrome tanning. The difference from the above method of tanning is that at the beginning of retanning, Zo / o salt is produced, and the consumption of chromium oxide is 0.5-1o / o of the weight of the planed stake.
Предмет изобретени Subject invention
Способ дублени кож, заключающийс в том, что голье после пикелевапи последовательно обрабатывают дубител ми, с последующим воздействием уротропином, отличающийс тем, что, с целью улучшени качества кож, воздействие уротропином производ т после обработки кож каждым из дубителей.The method of tanning leather, which consists in the fact that after the pickpels, the peel is successively treated with tanning agents, followed by exposure to hexamine, characterized in that, in order to improve the quality of leather, the exposure to hexamide is produced after the treatment of the leather with each tanning agent.
