Ukulungiswa kunye nezicelo zeMagnesium Hydroxide

I-Magnesium hydroxide, i-inorganic chemical ekrwada imathiriyeli ekrwada ene-chemical formula Mg(OH)₂, ayinayo-ityhefu, ayinavumba, kwaye izinzile ngokwe thermally. Isetyenziswa kakhulu kwi-flame retardants, amayeza, kunye nokhuseleko lokusingqongileyo. Iindlela zayo zokulungiselela ziyahluka, kubandakanywa imvula yetyuwa ye-magnesium, i-hydrothermal synthesis, kunye nemvula ethe ngqo.

Indlela yokugalelwa kwetyuwa ye-magnesium yeyona nkqubo ixhaphakileyo yokulungiselela ishishini. Ngokuqhelekileyo isebenzisa i-magnesium chloride (MgCl₂) okanye i-magnesium sulfate (MgSO₄) njengezinto eziluhlaza, ezisabela nge-sodium hydroxide (NaOH) okanye i-calcium hydroxide (Ca (OH) ₂) ukwenza i-precipitate ye-magnesium hydroxide. Le ndlela ilula ukuyisebenzisa kwaye iphantsi kweendleko, kodwa ukucoceka kwemveliso kuchaphazeleka kakhulu ngezinto eziluhlaza, ezifuna ukuhluzwa, ukuhlamba, kunye nokomisa ukuphucula umgangatho. Indlela ye-hydrothermal synthesis, eqhutywa phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, inokuvelisa{3}}ubunyulu,{4}icaciswe kakuhle i-magnesium hydroxide ngokulawula iimeko zokusabela (ezifana ne-pH, ubushushu kunye nexesha). Ilungele{6}usetyenziso oluphezulu olufana namayeza kunye nemathiriyeli yombane. Indlela yemvula ngokuthe ngqo ibandakanya ukusabela kwe-magnesium ore (efana ne-magnesite) kunye ne-asidi ukwenza ityuwa ye-magnesium, ethi iphendule nge-alkali ukuvelisa i-magnesium hydroxide. Le ndlela isebenzisa uluhlu olubanzi lwemathiriyeli ekrwada, kodwa inkqubo inde.

Ngokubhekiselele kwizicelo, i-magnesium hydroxide isetyenziswa ngokuyintloko njenge-flame retardant. Ukubola kwayo kubamba ubushushu kwaye kukhuphe umphunga wamanzi, kuthintela ngokufanelekileyo ukutsha. Ikwasetyenziswa kunyango lwamanzi amdaka njenge-neutralizer yokususa izinto ezingcolisa iasidi. Kwintsimi yamachiza, inokusetyenziswa njenge-antacid ukukhulula i-asidi egqithisileyo yesisu. Kwiminyaka yakutshanje, ngokunyuka kweemfuno zokusingqongileyo, ukusetyenziswa kwe-magnesium hydroxide kwi-flue gas desulfurization kunye ne-adsorption yentsimbi enzima iye yanda ngokuthe ngcembe.

Kwixesha elizayo, ngokulungiswa kobuchwepheshe bokulungiselela, obufana nophuhliso lwenano{0}}ubungakanani bemagnesium hydroxide, ukusebenza kwayo kuya kwandiswa ngakumbi, ukuyivumela ukuba idlale indima ebalulekileyo{1}}kwixabiso{2}}imimandla eyongeziweyo.
