Magnesium oxide plays an important role in leather processing.The following is a detailed introduction to the role of magnesium oxide in leather processing:

Promote softening of raw leather:In the early stages of leather blending,raw leather is usually relatively hard and difficult to process further.At this point,the addition of magnesium oxide can significantly promote the softening process of the skin.Magnesium oxide reacts with water to produce magnesium hydroxide,which releases heat during the reaction process and helps accelerate protein hydrolysis in the raw skin,making it soft and easy to process.At the same time,magnesium hydroxide also has good adsorption performance,which can adsorb oils and impurities in raw hides,further improving the quality of raw hides.

Adjusting the pH of the blending solution:In the leather blending process,the pH of the blending solution has a significant impact on the quality of the leather.Magnesium oxide,as an alkaline substance,can effectively regulate the acidity and alkalinity of the blending solution,keeping it within an appropriate range.This not only ensures the softness and elasticity of the leather,but also prevents quality issues such as cracking and hardening during subsequent processing.

Improving the water and oil resistance of leather:The addition of magnesium oxide can significantly enhance the water and oil resistance of leather.During the blending process,magnesium oxide reacts chemically with proteins in leather to form stable chemical bonds.These chemical bonds can effectively prevent the penetration of moisture and oil,thereby improving the water and oil resistance of leather.This allows leather to maintain good appearance and performance even in damp and greasy environments.

Enhancing leather dyeing and glossiness:In the later stages of leather blending,dyeing and finishing are key processes.The addition of magnesium oxide can significantly improve the dyeing and glossiness of leather.On the one hand,magnesium oxide can undergo complexation reactions with dye molecules,making it easier for the dye to penetrate into the interior of leather,thereby improving its dyeability.On the other hand,magnesium oxide can also react with oils and fats in leather to form a smooth thin film,making the leather surface smoother and brighter.

Environmental Protection and Sustainability:With the increasing awareness of environmental protection,the leather industry has higher requirements for raw materials.Magnesium oxide,as an environmentally friendly inorganic compound,has significant environmental advantages in the application of leather blending.Firstly,the production process of magnesium oxide is relatively simple and does not produce a large amount of pollutants.Secondly,magnesium oxide is used less in the leather blending process and is easy to recycle and reuse.This can not only reduce production costs,but also minimize pollution and damage to the environment.

In summary,the application of magnesium oxide in leather processing has multiple advantages and potential.With the advancement of technology and the expansion of applications,the use of magnesium oxide in leather processing will become more extensive and in-depth.
