Activated Alumina

详情

Activated alumina is to meet the need of deep dryness, approus air and transformation absorbent dryness in petrochemicals. The activated alumina we produce is high intension X-ρ Alumina product with stoma. It has a strong affinity for water so that it is suitable for microwater deep desiccation. When applied in a medium, it will neither become soft nor swell and never dissolve into powders. As a result, this product is widely used in gaseous and liquidoid desiccation in petrochemical industry. In addition, it is also widely applied as instrument wind in texitile, oxygen-making and automation industry. The product in different ball diameter can be manufactured with different technical condition if to users request.
