Application of caustic soda in the leather industry

Baking soda or sodium hydroxide is one of the strongest chemicals. This material is solid and scaly, which is white in color. Baking soda is made with the chemical formula of NaOH. Perak soda with 98% purity is very strong and concentrated, that's why it is considered a corrosive solution and should not come into contact with metals. Sood Perak is one of the most important materials widely used in various industries such as oil and petrochemical, cosmetics and hygiene, water and sewage, food industry, various detergents and most importantly the leather industry, which plays an important role in this industry. One of the most important uses of this material should be considered the use of perak in the leather industry. This material can be used as a degreaser in the leather industry. In this article, we will discuss the role of perk profit in leather production workshops in more detail. Applications of Sood Perak in the leather industry One of the important uses of perak is in the leather industry. In this industry, raw materials are transformed into leather in stages. Baking soda or caustic soda is used in the leather industry after depilation and removal of wool and excess proteins from the skin, using lime for the degreasing process. Some skins, such as sheep, which have a lot of fat, must be removed before tanning. Baking soda or caustic soda has high solvent and corrosive properties and can dissolve fats in itself, for this reason, this material is used in leather factories and workshops to remove leather from the skin. The price of Sood Perak is also cheaper than other degreasers, and for this reason, its use in the industry is economically justified. Skin hair removal method by Sood Perak In factories and leather production workshops, at the beginning of the work, wool and hair keratin are exposed to alkaline substances, so that the chemical bond of sulfur is broken by hydroxide in the cystine chain. The hair is first attacked by alkali in its root, which is not fully developed. After a certain period of soaking the skin in the alkaline soda solution, the hair roots dissolve in it. But when removing the hair from the skin of sheep and lamb on the inner surface of the skin, the fluff is used. In this way, the alkaline solution can penetrate inside the skin and attack the root. With this method, wool and hair are easily removed. This process is the basis of depilation of wool with the use of perk soda, which includes a large part of the world's leather products, and in this way, unwanted hair is removed and separated from the skin. In this way, after the process of hair removal and removing excess proteins from the outer surface of the skin, the process of removing fats is done. As you know, pitch soda is very corrosive and can easily dissolve fats inside itself, so we can say that pitch soda has many uses in the leather industry. The degreasing property of Sodperak is so high that it enjoys a great reputation in the industry of using Sodperak as a degreaser. In this article, we tried to mention this property in the field of removing animal fat in order to produce leather products.
