颗粒凹凸棒石粘土干燥剂的性能研究

通过加入某种添加剂能显著改善凹凸棒石粘土的吸湿性能，当添加剂的加入量达15％时，其在不同湿度下的吸湿率均高于常用干燥剂变色硅胶，且添加剂无毒、无污染，价格便宜，可作为生产凹凸棒石粘土干燥剂的添加剂使用。本文对含添加剂15％的颗粒凹凸棒石粘土干燥剂进行实验，获得了颗粒大小、烧结温度对吸湿量及颗粒强度的影响，并通过加入粘结剂的方法，保证了颗粒凹凸棒石粘土干燥剂吸湿后的强度。

Research on Property of Granulated Attapulgite Clay Desiccant

Moisture absorption ability of attapulgite clay can be improved remarkably through adding an additive. The moisture absorption rate of attapulgite clay with 15% additive is higher than silica gel under different relative humidity. The additive is nontoxic, non-pollution and cheap, so it can be used of production of attapulgite clay desiccant. In this paper, we make an experiment on granulated attapulgite clay desiccant with 15% additive, obtain the effect on moisture absorption capacity and granule intensity of the granule size and sintering temperature. The intensity of granulated attapulgite clay desiccant after absorbing moisture can be enhanced by adding adhesive.
