凹凸棒粘土的产品开发与利用

Product Development and Utilization of Attapulgite

凹凸棒粘土是一种自然界较稀少、性能独特、用途广泛的非金属矿产。凹凸棒粘土流变性良好,具有独特的胶体性能,是理想的无机胶凝材料,其表面物理化学结构及离子状态使其具有良好的吸附性能。凹凸棒粘土具有载体功能,可作为催化剂的载体,同时还可作为缓释肥料和农药的载体。凹凸棒粘土表面有结构残基、表面羟基使其具有补强性能,在石油、化工、食品、环保、农药、医药、建材等领域得到了广泛的应用。利用我国凹凸棒土资源丰富的特点,加快技术创新,使我国凹凸棒粘土工业跻身于世界先进之列。

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 carder function, it could be used as carrier of slow release fertilizers and pes- ticides. 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.
