Khoom Performance:
A dawb gel (ntub) los yog hmoov (qhuav), ntxhiab, cov mov thiab havzoov. Nws yog ib tug thixotrope nrog lub cim ntawm purity crystalline theem, YAV TOM NTEJ GELATION thiab muaj zog caking cov cuab yeej.
Nws yog ib tug xis mas ntawm lub ntes catalyst rau semi-hluavtaws tsawg-lub ntiaj teb Y molecular sieve, ib tug xis mas nyob rau hauv txhuas silicate refractory fiber, ib lub hauv paus nyob rau hauv ua ethylene los ntawm dej cawv lub cev qhuav dej thiab nyob rau hauv ua epoxy ethane. Nws kuj yuav siv tau raws li raw khoom rau tshuab txais alumina thiab lwm yam aluminates.
Pseudoboehmite Daim ntawv:
1. FCC thiab hydrogenation catalyst cab kuj.
2. Maas nyob rau hauv txhuas silicate refractory fiber.
3. Catalyst nyob rau hauv ua ethylene los ntawm dej cawv lub cev qhuav dej thiab nyob rau hauv ua epoxy ethane.
4. Siv raws li raw khoom rau tshuab txais alumina thiab lwm yam aluminates.
