Production information

Activated alumina has better Mechanical properties and heat resistance, there is no soft expansion and cracking when are immersed in water, the dew point of materials is dried by activated alumina can be lower than -40℃. This product can be used as precious metal catalyst carrier, oxygen generation industry, textile industry, gas drying, automatic instrument wind drying, as well as in chemical fertilizer, petrochemical drying industry as desiccant, purifier (dew point can reach -40℃). It is a kind of efficient deep drying desiccant with trace water, which can meet the standard of ISO8573-1 secondary water content and meet the requirements of most industries. It is very suitable for micro heat, blast heat and compression heat regeneration device.
