I-alumina powder iyisisetshenziswa esiyinhloko se-alumina grit emhlophe ehlanganisiwe nezinye izinto ezihuquzelayo, ezinezimpawu zokumelana nokushisa okuphezulu, ukumelana nokugqwala kanye nezakhiwo ezizinzile.I-Nano-alumina XZ-LY101 iwuketshezi olungenambala futhi olusobala, olusetshenziswa kabanzi njengezithasiselo kuma-resin ahlukahlukene e-acrylic, ama-polyurethane resins, ama-epoxy resins, njll. ezintweni zokumboza ingilazi, amatshe ayigugu, izinto zensimbi ezinembayo, njll.;futhi izinhlobo ezahlukene ze-alumina powder zinokusetshenziswa okuhlukile.Okulandelayo kugxile ekwethuleni ukusetshenziswa kwe-α, γ, kanye ne-β-uhlobo lwe-alumina powder.
1.α-alumina powder
Ku-alpha-type alumina powder, ama-ion omoya-mpilo apakishwe eduze ngendlela eyi-hexagonal, i-Al3+ isatshalaliswa ngokulinganayo esikhungweni se-octahedral coordination esizungezwe ama-ion omoya-mpilo, futhi amandla e-lattice makhulu kakhulu, ngakho-ke indawo yokuncibilika nendawo yokubilisa kukhulu kakhulu. phezulu.I-α-type oxidation I-Aluminium ayincibiliki emanzini ne-asidi.Ibizwa nangokuthi i-aluminium oxide embonini.Yimpahla eyisisekelo esetshenziswayo yokwenza i-aluminium yensimbi;iphinde isetshenziselwe ukwenza izitini ezihlukahlukene eziphikisayo, izinsimbi eziphikisayo, amapayipi aphikisayo, nezinsimbi zokuhlola izinga lokushisa eliphezulu;ingasetshenziswa futhi njenge-abrasive, i-flame retardant High-purity alpha alumina iphinde ibe impahla eluhlaza ekukhiqizeni i-corundum yokwenziwa, i-ruby yokwenziwa nesafire;iphinde isetshenziselwe ukukhiqiza i-substrate yamasekethe ahlanganisiwe amakhulu wesimanje.
2. γ-alumina powder
I-γ-uhlobo lwe-alumina i-aluminium hydroxide ku-140-150 ℃ uhlelo lokuqeda izinga lokushisa eliphansi kwemvelo, imboni ibizwa nangokuthi i-alumina esebenzayo, i-aluminium glue.Isakhiwo se-ion ye-oxygen eseduze yohlangothi olume mpo lwesikhungo sipakishwe eduze, i-Al3 + isatshalaliswa ngendlela engavamile ku-ion yomoya-mpilo ezungezwe izikhala ze-octahedral kanye ne-tetrahedral.γ-uhlobo lwe-alumina olungancibiliki emanzini, lungancibilika ku-asidi eqinile noma isixazululo se-alkali esiqinile, izoshiswa ibe ngu-1200 ℃ yonke izoguqulelwa ku-α-uhlobo lwe-alumina.I-γ-uhlobo lwe-alumina luyi-porous material, indawo yangaphakathi yegremu ngayinye ifinyelela emakhulwini wamamitha-skwele, umthamo ophezulu wokukhangisa womsebenzi.Umkhiqizo wezimboni uvame ukuba yizinhlayiyana eziyisilinda ezingenambala noma ezibomvana kancane ezinokumelana nokucindezela okuhle.Embonini yokucwenga i-petroleum kanye ne-petrochemical ivame ukusetshenziswa njenge-adsorbent, i-catalyst kanye ne-catalyst carrier;embonini uwoyela we-transformer, i-ejenti ye-turbine oil deacidification, esetshenziselwa ukuhlaziya ungqimba lombala;elabhorethri kukhona i-desiccant eqinile engathathi hlangothi, amandla ayo okomisa awekho ngaphansi kwe-phosphorus pentoxide, ngemva kokusetshenziswa kokulandelayo 175 ℃ ukushisa 6-8h kungabuye kuvuselelwe futhi kusetshenziswe kabusha.
3.β-alumina powder
I-β-type alumina powder nayo ingabizwa ngokuthi i-alumina powder esebenzayo.Impushana ye-alumina ecushiwe inamandla amakhulu okusebenza, i-hygroscopicity eqinile, ayivuvukali noma iqhekeke ngemva kokumunca amanzi, angenabuthi, angenaphunga, ayincibiliki emanzini ne-ethanol, ine-adsorption eqinile ye-fluorine, esetshenziselwa kakhulu ukukhishwa kwe-fluoride emanzini okuphuza ezindaweni ezine-fluorine ephezulu. .
I-alumina ecushiwe inekhono lokukhetha amanzi aphuma kumagesi, umhwamuko noketshezi oluthile.Ngemuva kokugcwala kwe-adsorption, ingavuselelwa ngokukhipha amanzi ngokushisisa cishe.175-315°C.I-Adsorption nokuvuselela kungenziwa izikhathi eziningana.Ngaphezu kokusetshenziswa njenge-desiccant, ingaphinda ifake umhwamuko ovela ku-oxygen engcolile, i-hydrogen, i-carbon dioxide, igesi yemvelo njll. yamafutha okugcoba.Ibuye isetshenziswe njengesithwali se-catalyst kanye ne-catalyst futhi njengesithwali sokuhlaziya ungqimba lombala.
