產(chǎn)品介紹

　　它是氧化鋁過(guò)渡相的一種型態(tài)，其主晶相為ρ氧化鋁機，主要成分為AL2O3。ρ氧化鋁采用氫氧化鋁經(jīng)懸浮焙燒快速脫水，并急冷制得，一般比表面積在240平方米/克以上，故具有較強的活性和吸水性能，并有一定的水化活性。活性氧化鋁是具有吸附性能、催化活性的多孔性，高分散度、大比表面積的氧化鋁。活性氧化鋁球按內部主晶組成分為γ型和χ-ρ型，按其用途可分為活性氧化鋁球吸附劑、活性氧化鋁球干燥劑和活性氧化鋁球催化劑載體。

用途

　　1、可替代純鋁酸鈣水泥用于高檔不定型耐火澆注料的結合劑，也可代替硅微粉和超細氧化鋁粉，用于高檔剛玉制品的粘合劑和結合劑。

　　2、可作為吸附劑、吸水劑及活性氧化鋁載體，廣泛用于石油、化工、醫藥、衛生等行業(yè)。

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.
