activated alumina dryer

Primary surpply of CNPC and CPPC
ISO9001:2000
activated alumina manufacture for 10 years
have drafted Industrial Standard

KA401 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in 

a way that produces a highly porous material; 

KA402 activated alumina is also widely used to remove fluoride from drinking water.  Basically, 

the more alumina in the filter, the less fluoride will be in the final, filtered water. 

KA403 is for absorbent H2O2

KA404 is for chlorine absorbent

KA405 in hydrogen peroxide production, as a selective adsorbent for many chemicals including,in  removal from gas streams .

KA406 activated alumina is used as a charge material in foreline traps to prevent  generated by  from 

backstreaming into the system 

Industry standard HG/T39272007 Activated Alumina is issued by Pingxiang Global Chemical Packing Co., Ltd
