activated alumina, pseudoboehmite, Zibo Xiangrun Environment Engineering Co.,Ltd

Products


Except high SiO2 Macroporous pseudo boehmite, Zibo Xiangrun and Shandong Bairui also produce Low SiO2 macroporous pseudo boehmite.

Pseudo boehmite,MF AI2O3.H2O(1.2-2.2). Macro pore volume pseudoboehmite is also called aluminum hydroxide dry glue or macroporous pseudoboehmite, a hydrate alumina, false monohydrate soft diaspore. It can used in different application according to the different production process .We use high purity aluminium hydroxide and ionic membrane alkali as raw materials, after the carbonation to produce series of macroporous pseudo boehmite( macroporous pseduboehmite) with different process. The pore volume of our macroporous pseudoboehmite is 0.8-1.2ml/g.
