Abstract
Сущность изобретени отмок у шкур крупного рогатого скота провод т осветленным водным отстоем сланцевой золы с расходом эопы 5-15 кг на 1 т сырь SUMMARY OF THE INVENTION Soaking in cattle hides is carried out with clarified water sludge from shale ash with an eope consumption of 5-15 kg per 1 ton of raw material
Description
Изобретение относитс к кожевенной промышленности, а именно к химической обработне шкур на подготовительной операции - отмоке сырь мокросолрного консервировани при производстве ко дл обувиThe invention relates to the leather industry, namely to the chemical processing of hides in a preparatory operation - soaking wet-salted canning raw materials in the manufacture of shoes
Известен способ огмоки без предварительной промывки сырь при Ж ; 1,3-1,0. температуре 27-29°С в течение б ч с использованием известкового молока с концентрацией CafOH h - 0 25- 0,30% 1The known method ogmoki without preliminary washing of the raw material at W; 1.3-1.0. at a temperature of 27-29 ° C for one hour using milk of lime with a concentration of CafOH h - 0 25-0.30% 1
Недостаток данного способа - использование дефицитного известкового молока а также значительные трудности в те ноло- гии его приготовлени The disadvantage of this method is the use of scarce milk of lime and significant difficulties in the technology of its preparation
Цель изобретени - повышение вывода готовы кож, снижение себестоимости продукции , использование отходов производства и унификаций реагентовThe purpose of the invention is to increase the output of ready-made skins, reduce production costs, use production wastes and unify reagents
Поставленную цепь достигают тем, что огмоку провод т осветленной водной выт жной сланцевой золы вл ющейс отходом сжигани горючих сланцев, сThe delivered circuit is achieved by the fact that a clarified aqueous exhaust shale ash is a waste product, which is a waste product from burning oil shale, with
концентрацией Ca(OHh 1,5-1,7 г/л, КОН- 2-4 г/п (приготовление отсто - 100 кг золы распупьповали в Юм воды в течение 5- 10 мин после чего пульпу отсто ли в течение 30 мин отстой направили на операцию отмок и) Отмену провод т при температуре 27-29°С в течение 4-8 ч (в зависимости от сорта сырь ) с расходом золы 5-15 кт на I т сырь concentration of Ca (OHh 1.5-1.7 g / l, KOH-2-4 g / p (sludge preparation - 100 kg of ash were discharged in water for 5-10 minutes, after which the sludge was sedimented for 30 min directed to the operation soaking and) Cancellation is carried out at a temperature of 27-29 ° C for 4-8 hours (depending on the type of raw material) with an ash flow rate of 5-15 kt per I ton of raw material
Унифик аци реагентов достигаетс тем, что сланцева зола используетс на других технологических операци при производстве ко: дл верха обуви - при золении сырь , очистке сточных водThe unification of reagents is achieved by the fact that shale ash is used in other technological operations in the production of co: for shoe tops - in case of raw materials ashing, wastewater treatment
При проведении сравнительных опытны работ пока зани, что с применением водной сланцевой золы на операции отмош повышаетс удельный готовой продукции в среднем на 1 %When conducting comparative experimental work, it is shown that with the use of water shale ash in operations, the specific finished product is increased by an average of 1%
