I-Alumina iyinto evamile engeyona eyensimbi, esetshenziswa kabanzi embonini, kwezokwakha, kwezobuchwepheshe, kwezokwelapha nakweminye imikhakha.

I-Alumina Isingeniso

I-Alumina iyimpushana emhlophe noma emhlophe enefomula ye-molecular ye-Al2O3 kanye nesisindo samangqamuzana angu-101.96.Kuyinhlanganisela eyakhiwe nge-aluminium nomoya-mpilo, enephuzu eliphezulu lokuncibilika nobulukhuni.I-Alumina iyimpahla eluhlaza ebaluleke kakhulu yezimboni, esetshenziswa kabanzi kuma-ceramics, ingilazi, i-electronics, imithi kanye neminye imikhakha.

Izici zomzimba ze-alumina

Izakhiwo ezibonakalayo ze-alumina ikakhulukazi zihlanganisa ukuminyana, ubulukhuni, ukuzinza kokushisa, izakhiwo ze-optical nokunye.Ukuminyana kwe-alumina kungu-3.9-4.0g/cm3, ubulukhuni buwubulukhuni be-Mohs 9, ukuzinza kwe-thermal kuphezulu, futhi indawo yokuncibilika ingu-2054 ℃.Ngaphezu kwalokho, i-alumina nayo inezindawo ezinhle zokubona futhi iyimpahla ebalulekile yokubona.

Izici zamakhemikhali ze-alumina

Amakhemikhali e-alumina ikakhulukazi ahlanganisa ukusebenza kokusabela ngezinto ezihlukahlukene zamakhemikhali, i-asidi ne-alkali.I-alumina ihlangana ne-asidi yakhe i-aluminium kasawoti namanzi, kanye ne-alkali ukwenza i-aluminium hydroxide namanzi.Ngesikhathi esifanayo, i-alumina nayo inezakhiwo ze-acidic oxides, ezingasabela ngamakhemikhali amaningi.

Indlela yokulungiselela i-alumina

Izindlela eziyinhloko zokulungiselela i-alumina yindlela yamakhemikhali, indlela yomzimba nokunye.Indlela yamakhemikhali iwukusabela kokungathathi hlangothi kwe-aluminiyamu kasawoti kanye ne-hydroxide ukuze kutholwe i-aluminium hydroxide, bese kuba ngokushisa okuphezulu kwezinga lokushisa ukuze uthole i-aluminium oxide.Indlela engokwenyama ngokuyinhloko iwukubola kwe-ore, i-distillation, i-crystallization nezinye izinyathelo zokuthola i-alumina.

Inkambu yesicelo se-Alumina

I-Alumina isetshenziswa kabanzi embonini, kwezokwakha, kwezobuchwepheshe, kwezokwelapha nakweminye imikhakha.Emkhakheni wezimboni, i-alumina isetshenziswa ekwenzeni i-ceramics, ingilazi, i-coatings nokunye.Emkhakheni wokwakha, i-alumina isetshenziselwa ukukhiqiza iminyango, iWindows, izindonga zamakhethini nokunye.Emkhakheni we-electronics, i-alumina isetshenziselwa ukwenza amabhodi wesifunda, izingxenye ze-elekthronikhi, njll. Emkhakheni wezokwelapha, i-alumina isetshenziswa ekwenzeni izidakamizwa, amadivaysi ezokwelapha nokunye.

Ithemba lokuthuthukiswa kwe-alumina

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, inkambu yokusetshenziswa kwe-alumina iyanda kakhulu.Esikhathini esizayo, ngokuthuthukiswa okusheshayo kwezinto ezintsha, amandla amasha kanye neminye imikhakha, isidingo se-alumina sizoqhubeka sikhula.Ngesikhathi esifanayo, ngokuthuthukiswa okuqhubekayo kwezidingo zokuvikela imvelo, ubuchwepheshe bokukhiqiza be-alumina buzoqhubeka buthuthuka, futhi izindlela zokukhiqiza ezinobungani bemvelo, eziphumelelayo nezonga amandla zizoba umkhuba wokuthuthukiswa.

I-Alumina iyimpahla ebalulekile engeyona eyensimbi, enezinhlobonhlobo zokusetshenziswa kanye nenani elibalulekile lezomnotho.Esikhathini esizayo, ngokuthuthukiswa okusheshayo kwezinto ezintsha namandla amasha kanye neminye imikhakha, isidingo se-alumina sizoqhubeka sanda, kuyilapho ubuchwepheshe bokukhiqiza be-alumina buzoqhubeka buthuthuka, futhi bube negalelo elikhulu ekuthuthukiseni abantu.
