Abstract

COMPOSITION FOR PRESERVING FUR RAW MATERIALS, mainly carakul and smushko-merushkovogo, including a tanning agent, sodium chloride, ammonium bleach, and water, from l and chaga and with the aim of intensification. Because of the shortening of the treatment process, it additionally contains sodium monoester sulfuric acid and a mixture of cetyl and oleyl alcohols, and ethylene diamine tetraacetateamino) zinc: 1 g (tetraamino) acid as the tanning agent, in the following ratio of components, g / l: Ethylenediaminetetra tato (amino) zinc-3 (tetraamine) zinc-3O-11O Sodium chloride 5-30 Ammonium chloride 5Q-100a ® Sodium salt of mono ester acid and a mixture of scatyl and oleyl alcohols. 3-8 Water Up to 1 l

Description

4 :: Ot C GS 110 The invention relates to light permeability and can be used in the preservation of fur raw materials. The most common is the preservation of Karakup, which consists in the processing of the washed and washed paired skins with sodium chloride with subsequent laying and drying f 1 3. However, raw materials treated in this manner have a relatively low welding temperature value, a high swelling of leather. In addition, raw materials treated with sodium chloride are subjected to damage by a mole of 35–40% and leather to 10–14% of the area during 2 months of storage, as well as during subsequent irrigation unstable to the action of autolysis and putrefactive processes. Moreover, the treatment of paired skin with sodium chloride is characterized by a long duration (5-7 days), insufficiently effective dehydration of the raw material (by 15-2%) and longer (486O, h) followed by drying. Closest to the present invention is a composition for preserving fur raw materials, including oak agent, sodium chloride, ammonium chloride, and water. As an oak agent, the composition contains alumina 2J. However, when processing this composition, the duration of preservation is a significant amount (18-48 hours). In addition, after finishing the processing of the raw material with a preservative, it is necessary to carry out a bedding (at least 24 hours). The purpose of the invention is to intensify the preservation process. (This goal is achieved by the fact that the composition for preserving fur raw materials, predominantly karakul and cinnamon, including a tanning agent, sodium chloride, ammonium chloride, and water, additionally contains sodium monoether sulfuric acid and a mixture of cetyl and oleyl alcohols, and ethylene diamine tetraacetate (amino) zinc (tetraamino) zinc as the oak agent in the following ratio of components, g / l: E and ilencyamine is the tract (amino) zinc tetraamshlo) zinc 4 O-110 32 sodium chloride 5-30 ammonium chloride 5O-. 1OO Sodium Salt Mo sulfuric acid noester and mixtures of cetyl and oleyl alcohols 3-8 Water up to 1 l. The hides are processed by sanding (by exposing them to maturation with an exposure time of 45-12 minutes, squeezing and subsequent drying. Table. 1 shows the composition for preserving The effectiveness of the composition is ensured by the simultaneous associated dehydration of the hides, which leads to an improvement in the physicomechanical characteristics of the leather tissue. The temperature of the welding is increased to 59-67 ° C, the degree of swelling is reduced to 0.1 n. caustic soda up to 130-280%, increase in load at break up to 17-25 kg, decrease in hair solubility in OD n.MaONdo 8.5-13%, decrease in abrasion up to 5.2-6; 1%, increase in hair rupture strength up to 31-33%, increasing the strength of the bond between the hair and the dermis, characterized by a hair loss of no more than 8-47 hairs with 1 dm under the mixed effect in a standard way. Preservation in the proposed composition is 6-10 times faster than the processing of NoiCE skins. Skins, preserved by this method, are not broken, watering for 3-4 hours, resistant to autolytic and putrefactive processes and are not affected by moths and leather. In tab. 2 given the physico-4 "1 Mechanical, chemical and biological characteristics of canned Karakul. The application of the proposed composition allows to reduce the processing time by 6 times compared with the prototype, while the multiplicity of application of the solution is 4-5, while lime composition allows the preservative solution to be used twice. In addition, the use of the proposed composition eliminates the need to spacers.
