Sodium hydrosulphide (NaHS) plays a key role in leather processing. Its unique chemical properties make it an indispensable raw material in the dehairing and tanning processes. In the initial stage of leather production, raw hides need to be dehaired to remove hair and residual tissue. Sodium hydrosulfide reacts with the proteins in the animal skin, destroying the connecting structure between the hair and the cortex, thereby effectively achieving the purpose of dehairing. This process not only maintains the integrity of the leather, but also lays the foundation for the subsequent tanning process.
In the tanning process, sodium hydrosulfide often works in synergy with other tanning agents to help enhance the flexibility and corrosion resistance of leather. Its alkaline properties help adjust the pH value of the tanning system and promote the penetration of tanning agent molecules into the leather layer, thereby improving the fullness and mechanical properties of the leather. In addition, sodium hydrosulfide can also be used to treat grease and impurities on the surface of leather to improve the appearance and texture of the finished product.
It is worth noting that the concentration and treatment time of sodium hydrosulfide 281090 must be strictly controlled during use to avoid excessive damage to leather fibers. At the same time, due to its corrosiveness and irritation, necessary protective measures must be taken during operation to ensure production safety. With its efficient depilatory effect and optimization of tanning process, sodium hydrosulfide has become one of the important chemical additives in the modern leather industry.
