Umkhiqizo Ukusebenza:
A gel emhlophe (ezimanzi) noma powder (omisiwe), ayinaphunga kunganambitheki futhi akunabo ubuthi. Kuyinto thixotrope nabalingiswa ephezulu msulwa crystalline isigaba, GELATION esihle futhi caking impahla eqinile.
Kuyinto okuqinisa ekwandeni ngokuhlaziya ngoba semi zokwenziwa ezingavamile-umhlaba Y ngesihlungo yamangqamuzana, usimende in aluminium silicate fibre refractory, kulethe ekwenzeni ethylene ngotshwala amanzi emzimbeni futhi ekwenzeni epoxy ethane. Iphinde ingasetshenziswa njengendlela impahla eluhlaza for alumina isebenze nezinye aluminates.
Pseudoboehmite Isicelo:
1. I-FCC kanye hydrogenation kulethe yenethiwekhi.
2. Usimende in aluminium silicate fibre refractory.
3. Catalyst ekwenzeni ethylene ngotshwala amanzi emzimbeni futhi ekwenzeni epoxy ethane.
4. Isetshenziswa njengesici impahla eluhlaza for alumina isebenze nezinye aluminates.

AG-50 uhlobo lwesakhiwo amorphous alumina ijeli, okungase elakhiwe sol ezinzile ngaphansi isenzo wezinto acid noma organic acid. It has adhesion enamandla kakhulu. I kulethe eyenziwe AG-50 has nemihuzuko ukumelana okuhle, coke kancane emikhiqizweni ukuphendula.
Ngokusebenzisa omiswe, lo mkhiqizo iba amorphous powder indwangu emhlophe. Ingasetshenziselwa ukwenziwa alikhali khulula ejenti kuyashesha, sishaye ukhonkolo, acid zokuyithena ejenti. Ukungeza ku usimende yashesha, ngeke unciphise coagulation ngesikhathi sako kwelulwe isikhathi isitoreji.
AG-50 lungasetshenziswa njengoba ukwelashwa surface fibre wezinto ezingaphili noma organic ngezici zawo ekuqiniseni. It kabanzi zobumba abaphezulu kanye zobumba yokukhiqiza ukuze esihle lokushisa ukubekezelelana ebusweni sekugcineni. Kungaba yamathebhu wezinto eziphambili Umdwebo ephepheni. Kuyinto esikhundleni we-titanium dioxide ngoba umsebenzi okwandisa iphepha olubushelelezi, mhlophe, umswakama ukumelana.
