Application of Magnesium Oxide in Pigments and Dyes

PH regulator:Magnesium oxide has excellent pH regulation ability and can effectively adjust the pH value of dyes to maintain it within an appropriate range.This is crucial for improving the dyeing effect and fiber quality.During the dyeing process,if the pH value is too high or too low,it will have adverse effects on the fibers,such as decreased strength and changes in color light.By adding an appropriate amount of magnesium oxide,the pH value of the dye can be stabilized within a reasonable range,thereby improving the dyeing quality.

Protective agent:Magnesium oxide also has the function of neutralizing acidic substances.During the preparation process of dispersed dyes,some acidic substances may be generated,which can reduce the durability and stability of the dyes.Magnesium oxide can effectively neutralize these acidic substances,thereby improving the durability and stability of dyes.

Absorbent:Magnesium oxide can also be used as a protective agent.During storage and transportation,magnesium oxide can absorb moisture and carbon dioxide from the air,thereby preventing dyes from getting damp and deteriorating.This is of great significance for maintaining the quality of dyes and extending their service life.

Refractory material:Lightweight magnesium oxide has a high refractory temperature and can maintain stability at high temperatures,effectively improving the refractory performance of coatings.This allows the coating to remain stable in high temperature environments,less prone to combustion or deformation,and protects the coated material from high temperature damage.

Enhanced hardness:Lightweight magnesium oxide itself has a high hardness,and adding it to the coating can significantly improve the overall hardness of the coating,thereby enhancing wear resistance and scratch resistance.This helps to slow down the damage to the coating during a fire and extend the service life of the coating.

Improving stability:The addition of lightweight magnesium oxide can improve the stability of coatings,reduce precipitation and delamination during storage and use,and ensure uniform distribution of various components in coatings.This helps to maintain the quality and performance of the coating and improve construction efficiency.

Sunscreen function:In sunscreen products,active magnesium oxide forms an invisible layer on the surface of the skin,reflecting ultraviolet rays and preventing most ultraviolet rays from penetrating the surface of the skin.This physical sunscreen mechanism is different from chemical sunscreen,as it does not absorb into the skin,thus reducing the risk of allergies and acne.

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