Sodium Formate for Leather Tanning
Products Description
In addition, sodium formate can also be used to control the acid-base balance in leather processing. In some processing processes, leather may need to undergo acidic or alkaline conditions to achieve a specific effect. Sodium formate can act as a buffer to adjust the acid-base balance in leather processing and ensure the stability and consistency of the processing process. This is very important for obtaining consistent product quality and appearance.
In addition, sodium formate also has antibacterial and antiseptic properties. During leather processing and storage, the growth of bacteria and fungi may cause leather to be damaged. Sodium formate can act as an effective preservative to inhibit the growth of bacteria and fungi and protect the quality and durability of leather.
In summary, the inorganic salt sodium formate plays a variety of key roles in the leather industry. It can be used as a component of tanning materials to promote the bonding of leather fibers and improve its texture; as a reducing agent to improve the color and quality of leather; as an acid-base balance controller to ensure the stability of the treatment process; and as a preservative to protect leather from bacteria and fungi. The application of sodium formate enables the leather industry to produce high-quality, durable and good-looking leather products.
Sodium formate is used as a camouflage acid in the leather industry to make the leather soft and delicate. The high-quality sodium formate content usually required is above 95%.Zibo Amila Company can provide the following content sodium formate:sodium formate 95%,sodium formate 97% and sodium formate 98%.We warmly welcome new and old customers to contact us by phone or email for inquiries about our high-quality sodium formate products.
What is more,sodium formate can be used as a bleaching agent for fabrics. It can effectively remove residual pigments and impurities produced during the dyeing process, making the fabrics whiter and brighter.
Effect of Sodium Formate on Leather in Tanning Process
Although sodium formate has many advantages in the leather making process, excessive or improper use will have a certain impact on the leather quality and the environment.
1. Affecting the water resistance and light resistance of leather
Sodium formate will produce a very strong acidic environment. Excessive use will make the pH value of leather too low, thereby reducing the water resistance and light resistance of leather, and even causing leather discoloration, aging and other problems.
2. Affecting the softness and breathability of leather
Although sodium formate can promote the softness and toughness of leather, excessive or improper use will also cause the leather to be too soft and lose balance, affecting the breathability of leather.
3. Pollution to the environment
Although sodium formate is a commonly used acid in the leather making process, excessive use will make the acidity in the leather making wastewater too high, causing pollution to the environment. In addition, the waste treatment of sodium formate also needs to be paid attention to avoid secondary pollution.
When using sodium formate in the leather making process, it is necessary to understand its mechanism of action and reasonable usage methods, while paying attention to reducing the negative impact of sodium formate on leather quality and the environment.
