Product Development and Utilization of Attapulgite

Attapulgite clay was a relatively rare non-metallic mineral but widely used in many areas because of its unique properties.It had good rheology and the unique colloidal property that made it a ideal inorganic cementitious material.The chemical and physical structure of its surface and the ion state gave itself an excellent adsorption property.Because of carrier function,it could be used as carrier of slow release fertilizers and pesticides.Besides,it also had a reinforcing property.Attapulgite clay was widely used in the areas of petroleum,chemical industry,food,environmental protection,pesticides,pharmaceutics and building.Through the technological innovation,we could promote the attapulgite clay industry of our country a big progress.
