Изобретение относитс к физикохимической обработке кожи и меха и может быть использовано при выделке шкур.The invention relates to the physicochemical treatment of leather and fur and can be used in the manufacture of hides.
По основному авт. св. № 488048 известен способ сушки пористых материалов , преимущественно шубной овчины , путем пропитки их органическим гидрофобным растворителем, не смешивающимс с водой, причем перед пропиткой материалов в гидрофобный растворитель добавл ют 10-15 вес.% гидрофильного органH4ecKjoro растворител , смешивающегос с. водой и гидрофобным растворителем р.According to the main author. St. No. 488048 is a method of drying porous materials, preferably fur sheepskin, by impregnating them with an organic hydrophobic solvent that is not miscible with water, and 10–15 wt.% Hydrophilic organ H4ecKjoro solvent that is miscible with is added to the hydrophobic solvent before the materials are impregnated. water and a hydrophobic solvent p.
Недостатком способа сушки вл етс длительность процесса и низкое качество.The disadvantage of the drying method is the process duration and low quality.
Цель изобретени - сокращение продолжительности процесса и улучшенке качества сушки.The purpose of the invention is to reduce the duration of the process and improve the quality of drying.
Указанна цель достигаетс тем, что в смесь гидрофобного и гидрофильного растворителей ввод т жирующие и дуб щие вещества и в процессе пропитки одновременно осуществл ют жирование и дубление высушиваемого материала .This goal is achieved by adding fatty and tanning substances to a mixture of hydrophobic and hydrophilic solvents, and, during the impregnation process, the drying material is tanned and tanned at the same time.
Способ сушки пористых материалов осуществл етс следующим образом.The method of drying porous materials is carried out as follows.
После необходимой подготовки, например пинелевание или солевание, кожанна ткань обрабатываетс смесью гидрофобного органического растворител с 10-30% гидрофильного органического растворител в течение 1015 мин. После этого в рабочую ванну добавл ют хромовый дубитель марки ДФ. После 2 ч обработки шкуры просуши- . After the necessary preparation, for example, lathing or salting, the leather is treated with a mixture of hydrophobic organic solvent with 10-30% hydrophilic organic solvent for 1015 minutes. After that, chromic tanning agent DF is added to the working bath. After 2 hours of processing the skins are dry.
0 ваютс потоком гор чего воздуха с температурой 45-50°С в течение 20-60 мин. Затем полуфабрикат, мину пролежку, увлажнение и первую откатку, поступает на ческу и далее на отделочные опе5 рации согласно технологической схеме обработки.This is a flow of hot air with a temperature of 45-50 ° C for 20-60 minutes. Then the semi-finished product, the laying mine, moistening and the first haulage, goes to the garlic and then to the finishing operations according to the processing flow chart.
Предлагаемый способ сушки, где одновременно происходит дубление, жирование и сушка, позвол ет уменьшить The proposed method of drying, where tanning, greasing and drying occur simultaneously, reduces
0 продолжительность процесса вьщелки шкур в два раза и улучшить использование сырь . Одновременно с этим исключаютс сточные воды.0 the duration of the process of latching hides twice and improve the use of raw materials. At the same time, wastewater is excluded.
