凹凸棒石粘土干燥剂的制备与性能研究

Study on the Property and Manufacturing of Attapulgite Desiccant

本文就利用凹凸棒石粘土制作干燥剂的实验研究作一介绍,通过加入一种或多种改性剂,有效的改善了凹凸棒石粘土的吸湿性能,并且在加入粘结剂制成球形颗粒后仍然能保持较高的吸湿率,吸湿后不变形,具有较高的强度,成本低,无污染,能反复再生使用。

The study on manufacturing of attapulgite desiccant was described in this paper. We can improve the adsorption property of attapulgiteeffectively with adding oneor several kinds of modifiers. When the attapulgite desiccant was made into spheroid particle after adding the modifiers, it can keep higher hygroscopic rate, have higherstrength and no deformation. This kind of desiccant costs little and frees from pollution, can beused regeneratively.
