1. Incazelo yomkhiqizo we-boehmite ohlongozwayo: Lo mkhiqizo awunabo ubuthi, awunambitheki futhi awunaphunga. Umkhiqizo omanzi uyi-colloid emhlophe kanti i-powder eyomile iyi-powder emhlophe. Ukusatshalaliswa kosayizi we-pore kuyafana, ivolumu inkulu futhi ukumuncwa kwamanzi kuhle. Unokuhlanzeka okuphezulu kwe-radial, ukusebenza kahle kokubumba kanye nezakhiwo ze-thixotropic gel. Umkhiqizo unokuhlakazeka okuhle, kulula ukuwuncibilikisa esixazululweni esinamandla se-asidi ne-alkali, futhi usebenza kahle ekubumbeni.
2. Ukupakishwa nokugcinwa kwe-pseudo boehmite: i-pseudo boehmite ipakishwa ezikhwameni ezilukiwe. Gcina endaweni yokugcina impahla epholile, enomoya omuhle futhi eyomile.
3. Ukusetshenziswa okuyinhloko kwe-boehmite ehlongozwayo:
Lo mkhiqizo usetshenziswa kakhulu njengezinto zokusetshenziswa zokusekela i-alumina esebenzayo, njengezinto zokusetshenziswa zokusekela i-hydrogenation, ukusekela i-hydrogenation catalyst kanye ne-oxychlorination catalyst.
Ingasetshenziswa futhi njenge-molding binder yemikhiqizo ye-zeolite kanye ne-silicate refractory fiber, njenge-binder ye-semi synthetic rare earth Y zeolite cracking catalyst.
Lo mkhiqizo uyinto eluhlaza enhle yokukhiqiza usawoti we-aluminium ohlukahlukene. Ngemva kokubumba, ungasetshenziswa njenge-desiccant, i-adsorbent kanye ne-catalyst carrier enezimo ezahlukene.
1. Ukwenza ngcono ukukhethwa kwemishini yokucubungula kanye nokuwasha nokuhlunga ngesihlungi sebhande le-vacuum lekamelo eliqinile elisebenza kahle kakhulu kuyisihluthulelo sokunciphisa ukusetshenziswa kwamanzi ahlanzekile ekukhiqizweni kwe-pseudo boehmite.
2. Isixazululo sesithathu sokuwasha sisetshenziselwa ukuhlanganisa isixazululo se-sodium aluminate ukuze kuncishiswe ukufuduka kwangaphandle futhi kuthuthukiswe ukusebenza kahle kwamanzi amasha. Kuyisinyathelo esibalulekile sokunciphisa ukusetshenziswa kwamanzi amasha.
3. Indlela eyinhloko yokunciphisa ukusetshenziswa kwamanzi amasha ukwandisa izinga lokushisa lokugeza amanzi ashisayo ngendlela efanele, ukwakha uhlelo lwenqubo olufanele kanye nokusebenzisa uhlelo lokupholisa oluhlukaniswe ngezigaba.
I-Pseudo boehmite uhlobo lwe-pseudo boehmite olune-crystallization engaphelele ye-colloidal. Imikhiqizo 1, ayinabo ubuthi, 2, ayinambitheki, 3, ayinaphunga, 4, ubumsulwa obuphezulu besigaba sekristalu, 5, ukuncibilika okuhle, 6, ukunamathela okuqinile, 7, enezici zejeli ze-thixotropic. I-Pseudo boehmite ingasetshenziswa kabanzi ku-petrochemical, umanyolo wamakhemikhali, imikhiqizo ye-silicate, ukuvikelwa kwemvelo kanye neminye imboni.
