Boehmite

Short Description:

A-AS-HC-GSA Boehmite ndi kalambulabwalo zofunika kwa yokonza γ-Al2O3 ndi α-Al2O3, makamaka ntchito chothandizira ndi zipangizo zake chonyamulira, chuma ❖ kuyanika, zikopa porous ndi zofewa zoumbaumba abrasive, mkulu kutentha etc.

Mankhwala Magwiridwe:
A gel osakaniza woyera (chonyowa) kapena ufa (zouma), odorless, zoipa ndi nontoxic. Ndi thixotrope ndi zilembo za mkulu chiyero crystalline gawo, kwambiri GELATION ndi amphamvu caking katundu.
Ndi simenti wa chothandizira akulimbana kwa theka-kupanga osowa-lapansi Y sieve maselo, simenti mu zotayidwa silicate refractory CHIKWANGWANI, ndi chothandizira kupanga ethylene mowa madzi m'thupi ndi kupanga epoxy ethane. Komanso angagwiritsidwe ntchito ngati zopangira kwa aluminiyamu adamulowetsa ndi aluminates ena.

Pseudoboehmite pankhaniyi:
1. FCC ndi hydrogenation chothandizira chonyamulira.
2. simenti mu zotayidwa silicate refractory CHIKWANGWANI.
3. chothandizira kupanga ethylene mowa madzi m'thupi ndi kupanga epoxy ethane.
4. Ntchito monga zopangira kwa aluminiyamu adamulowetsa ndi aluminates ena.
