Description
Предметол- изобретени вл етс способ обеззараживани кожевенного сьрь сол ми фтора в процессе производственной отлшки.The subject of the invention is a method of disinfecting the tanning industry with fluorine salts during manufacturing process.
Предлагаемый способ обеспечивает надежное обеззараживание по зерхностно-заражекного сибирской звой кожевеи 0го сырь без сииЛчсьм его качества, достигаетс это тем, что сырые кожи обрабатываютс в растворах, содержап,их фтористоводоро;| ,ную кислоту, получаемую иодкислепием серной кислотой раствора, содержащего повареиную соль и фтор ИСТЫ); и атрий.The proposed method provides reliable disinfection of the raw materials of the Siberian superficial-contagious animal without raw materials. This is achieved by the fact that raw skins are treated in solutions, containing fluoride fluoride; , Acidic acid, obtained by sulfuric acid iodine acid by solution containing povorovinuyu salt and fluorine ISTY); and atrium.
Дл дезкифекцим кожевенного сырь готов т раствор, содержащий 3 одном литре 10 г кремнефтористого натри ; 6,5-7,0 г серной кислоты (в пересчете на 100%-пую) и 100 г поваренной соли. Приготовленк ;: .ч раствором обрабатывают кожи пои температуре раствора 30- 32 3 течение 48 часов.A solution containing 3 to one liter of 10 g of sodium silicofluoride is prepared for dezifefecim of tannery; 6.5-7.0 g of sulfuric acid (in terms of 100%) and 100 g of salt. Prepared;: the solution is treated with the skin and the solution temperature is 30-32 3 for 48 hours.
Далее следует нейтрализаци кислоты к;: сы|)ье в вапие, содержли } 1 ; ОБаре;;иую соль и соду, при 30 и рН 5,5 - 6,0.This is followed by the neutralization of the acid to ;: sy | a th in vapie, contained} 1; Obare ;; other salt and soda, at 30 and pH 5.5 - 6.0.
