Ukuhlaziywa Komehluko Kumafomu Emvelo kanye Nezakhiwo Zamakhemikhali zeMagnesium Hydroxide

I-Magnesium hydroxide (Mg(OH)₂) iyinhlanganisela evamile ye-inorganic esetshenziswa kabanzi embonini, emithini, nasekuvikelweni kwemvelo. Kodwa-ke, kuye ngenqubo yayo yokulungiselela, ukuhlanzeka, kanye ne-microstructure, i-magnesium hydroxide ibonisa ukuhluka okuphawulekayo kwesakhiwo somzimba kanye nezakhiwo zamakhemikhali, ezithinta ngokuqondile ukusetshenziswa kwayo okusebenzayo.

Ngokusekelwe esimweni sayo somzimba, i-magnesium hydroxide ingahlukaniswa ngezinhlobo ezimbili: esindayo futhi elula. I-magnesium hydroxide enzima ivamise ukukhiqizwa ngokuhlanzwa okuqondile kwe-natural brucite ore noma ngokubala okuphezulu-kwezinga lokushisa kwezinto zokusetshenziswa njenge-magnesium chloride ne-magnesium sulfate. Inezinhlayiya ezinkudlwana kanye nokuminyana okuphezulu, ezethula ibhulokhi eliminyene noma isakhiwo se-flake. Ngokuyinhloko isetshenziswa njenge-filler ye-flame retardant noma impahla eluhlaza ye-ceramic. I-magnesium hydroxide ekhanyayo, ngakolunye uhlangothi, ivame ukuhlanganiswa yimvula yamakhemikhali. Isibonelo, isisombululo sikasawoti we-magnesium sisabela ngesisombululo se-alkaline (njenge-sodium hydroxide) ukukhiqiza impushana emhlophe. Izinhlayiya zayo ezihlakazeke kakhulu kanye nendawo enkulu ethile engaphezulu ihlinzeka ngezakhiwo ezithuthukisiwe zokumiswa kanye ne-adsorption, okuyenza isetshenziswe ngokuvamile ekuhlanzeni amanzi angcolile emvelo noma ama-antacid emithi.

Mayelana nezakhiwo zamakhemikhali, zombili izinhlobo ze-magnesium hydroxide zine-alkali, kodwa ukusebenza kwazo kabusha kuyahluka. I-magnesium hydroxide ekhanyayo, ngenxa yamandla ayo aphezulu, isengozini kakhulu ekuphenduleni kokungathathi hlangothi ngama-acids, okuvumela ukususwa ngokushesha kwama-ion ensimbi esindayo noma ukungcola okune-asidi ekuhlanzeni amanzi angcolile, isibonelo. Ngakolunye uhlangothi, i-magnesium hydroxide enamandla inezinga lokuphendula kwamakhemikhali elihamba kancane kodwa inikeza ukuzinza okushisayo okuvelele emazingeni okushisa aphezulu, okuyenza ifaneleke njengesithasiselo esibuyisela amalangabi sezinto ze-polymer. Umhwamuko wamanzi okhishwe ngesikhathi sokubola unganciphisa umoya-mpilo futhi wehlise izinga lokushisa elingaphezulu lempahla. Ngaphezu kwalokho,{4}}i-magnesium hydroxide ephezulu yokuhlanzeka (efana nebanga lezemithi) idinga ukulawula okuqinile kwamazinga okungcola ukuze kuqinisekiswe ukuphepha nokusebenza kwayo.

Kafushane, umehluko phakathi kwe-magnesium hydroxides udlulela ngale kwezakhiwo zawo ezibonakalayo ezinkulu futhi ube nomthelela omkhulu ezimeni zokusetshenziswa kwawo. Ukuqonda lo mehluko kungasiza ukuthuthukisa izinqubo zokukhiqiza zezidingo ezithile futhi kukhuphule inani lezinto ezibonakalayo.
