Activated alumina


Activated alumina provided by LABOO Purification Technology Co., Ltd. of Changzhou is a spherical particle with many capillary channels. It has strong affinity for polar substances such as water. It is a non-toxic and non-corrosive high-efficiency desiccant. The product has the characteristics of high static capacity, low wear, water-free and strong water absorption. The lowest dew point can reach - 70 C and the regeneration temperature is low (150 C). It is widely used in the deep drying of various vapor-liquid substances and the treatment of harmful impurities.
