Leather industry is a traditional industry, its production process needs to use a variety of chemical reagents, of which glacial acetic acid as an important chemical raw material, plays an important role in the leather industry. The application and research progress of glacial acetic acid in leather industry are discussed in this paper.
First, the application of glacial acetic acid in leather dyeing
Glacial acetic acid plays an important role in the dyeing process of leather. It can be used as a buffer to adjust the pH value of the dye, thereby improving the solubility and color performance of the dye. At the same time, glacial acetic acid can also enhance the binding force of dye and leather fiber, improve the uniformity and color fastness of dyeing. Therefore, glacial acetic acid has a wide range of applications in leather dyeing.
Second, the application of glacial acetic acid in leather tanning agent
Glacial acetic acid is also one of the important components of leather tanning agent. In the process of leather tanning, glacial acetic acid can be used as a catalyst to promote the cross-linking reaction of tanning agents and enhance the elasticity and wear resistance of leather. At the same time, glacial acetic acid can also adjust the pH value of tanning agent and control the rate and effect of tanning process. Therefore, the application of glacial acetic acid in leather tanning agent is of great significance to improve the quality of leather.
Third, the application of glacial acetic acid in leather coating
Glacial acetic acid also plays an important role in leather finishing. It can be used as a crosslinking agent and catalyst to promote the combination of the finishing agent and the leather fiber, and enhance the adhesion and water resistance of the coating. At the same time, glacial acetic acid can also adjust the viscosity and stability of the finishing agent and improve the finishing effect. Therefore, the application of glacial acetic acid in leather finishing can improve the finishing quality of leather products.
Fourth, the application of glacial acetic acid in the treatment of leather waste liquid
The waste liquid produced by leather industry contains a lot of harmful substances, which causes pollution to the environment. Glacial acetic acid can be used for the treatment of leather waste liquid, by adjusting the pH value and chemical properties of the waste liquid, promote the precipitation and degradation of harmful substances, so as to reduce the pollution degree of the waste liquid. Therefore, the application of glacial acetic acid in the treatment of leather waste liquid is of great significance for environmental protection.
In summary, glacial acetic acid has a wide range of applications in the leather industry. With the progress of science and technology and the emphasis on environmental protection, the application of glacial acetic acid in the leather industry will continue to be in-depth research to improve the quality of leather products and reduce the impact on the environment.
