1. Tsananguro yechinhu chinoda kuitwa cheboehmite: Chigadzirwa ichi hachina chepfu, hachina kunaka uye hachina hwema. Chigadzirwa chakanyorova chine colloid chena uye upfu hwakaoma ihupfu huchena. Kupararira kwepore kwakafanana, huwandu hwacho hwakakura uye mvura inonyungudika zvakanaka. Chine kuchena kwakanyanya, kushanda zvakanaka kwekugadzira uye hunhu hwethixotropic gel. Chigadzirwa ichi chinopararira zvakanaka, chiri nyore kunyungudika muasidhi yakasimba uye alkali solution, uye chinoshanda zvakanaka pakuumba.
2. Kurongedza nekuchengetedza pseudo boehmite: pseudo boehmite inorongedzwa mumabhegi akarukwa. Chengeta mudura rinotonhorera, rine mhepo inofefetera zvakanaka uye rakaoma.
3. Mashandisirwo makuru emhando yeboehmite inokurudzirwa:
Chigadzirwa ichi chinonyanya kushandiswa sezvinhu zvekusimbisa activated alumina, zvakaita sezvinhu zvehydrogenation catalyst, rutsigiro rwehydrogenation catalyst uye oxychlorination catalyst.
Inogona zvakare kushandiswa semuchina wekuumba wezvigadzirwa zve zeolite ne silicate refractory fiber, senge muchina wekuumba we semi synthetic rare earth Y zeolite cracking catalyst.
Chigadzirwa ichi chinhu chakanaka chekugadzira munyu wealuminium wakasiyana-siyana. Mushure mekuumbwa, chinogona kushandiswa se desiccant, adsorbent uye catalyst carrier ine maumbirwo akasiyana.
1. Kugadzirisa kusarudzwa kwemidziyo yekugadzira uye kuwacha nekusefa nefirita yebhandi revacuum rakagadzirwa nechamber rakagadzirwa zvine simba ndiyo nzira huru yekuderedza kushandiswa kwemvura yakachena mukugadzirwa kwepseudo boehmite.
2. Mushonga wechitatu wekuwachisa unoshandiswa pakubatanidza sodium aluminate solution kuderedza kusuduruka kwekunze uye kuvandudza mashandiro emvura itsva. Ichi chiyero chakakosha chekuderedza kushandiswa kwemvura itsva.
3. Nzira huru yekuderedza kushandiswa kwemvura itsva ndeyekuwedzera tembiricha yekugeza mvura inopisa, kugadzira sisitimu inonzwisisika uye kushandisa sisitimu inotonhodza yakakamurwa.
Pseudo boehmite rudzi rwe pseudo boehmite isina kukwana colloidal crystallization. Zvigadzirwa 1, haina chepfu, 2, haina kunaka, 3, haina hwema, 4, crystalline phase high purity, 5, inonyunguduka zvakanaka, 6, ine adhesion yakasimba, 7, ine hunhu hwethixotropic gel. Pseudo boehmite inogona kushandiswa zvakanyanya mu petrochemical, chemical fertilizer, silicate products, kuchengetedza zvakatipoteredza nedzimwe nzvimbo.
