ρ-氧化铝快脱粉(Alumina quick powder)

产品介绍

　　它是氧化铝过渡相的一种型态，其主晶相为ρ氧化铝机，主要成分为AL2O3。ρ氧化铝采用氢氧化铝经悬浮焙烧快速脱水，并急冷制得，一般比表面积在240平方米/克以上，故具有较强的活性和吸水性能，并有一定的水化活性。活性氧化铝是具有吸附性能、催化活性的多孔性，高分散度、大比表面积的氧化铝。活性氧化铝球按内部主晶组成分为γ型和χ-ρ型，按其用途可分为活性氧化铝球吸附剂、活性氧化铝球干燥剂和活性氧化铝球催化剂载体。

用途

　　1、可替代纯铝酸钙水泥用于高档不定型耐火浇注料的结合剂，也可代替硅微粉和超细氧化铝粉，用于高档刚玉制品的粘合剂和结合剂。

　　2、可作为吸附剂、吸水剂及活性氧化铝载体，广泛用于石油、化工、医药、卫生等行业。

Activated alumina powder Applications:It is a type of alumina transition phase. Its main crystal phase is ρ alumina machine and its main component is AL2O3. ρ alumina is produced by rapid dehydration of aluminum hydroxide through suspension roasting and rapid cooling. Generally, the specific surface area is above 240 square meters per gram, so it has strong activity and water absorption performance, and has a certain hydration activity. Activated alumina is a porous alumina with high adsorption and catalytic activity, high dispersion and large specific surface area. Activated alumina spheres are divided into γ-type and χ-ρ-type according to the internal main crystal composition. According to their uses, activated alumina spheres can be divided into activated alumina sphere adsorbents, activated alumina ball desiccants, and activated alumina ball catalyst carriers.

Uses: 1. It can replace pure calcium aluminate cement as a binder for high-grade unshaped refractory castables. It can also replace fine silica powder and ultra-fine alumina powder as a binder and binder for high-grade corundum products. 2. Can be used as adsorbent, water absorbent and activated alumina carrier, widely used in petroleum, chemical, pharmaceutical, health and other industries.
