Ukuqonda iiDesiccants: Indima yeAlumina esebenzayo

I-Desiccants zizinto ezifunxa ukufuma kokusingqongileyo, zizenza ziyimfuneko kumashishini ahlukeneyo okugcina ingqibelelo yeemveliso kunye nezixhobo. Phakathi kwezinto ezininzi ze-desiccants ezikhoyo, i-alumina esebenzayo ivelele ngenxa yeempawu zayo ezizodwa kunye nokuguquguquka.

I-alumina esebenzayo yindlela enemingxuma ephezulu ye-aluminium oxide, eyenziwe ngokuphatha i-aluminiyam hydroxide ngobushushu. Le nkqubo iphucula indawo yayo kunye nomthamo we-adsorption, okwenza kube yi-desiccant esebenzayo. Ngommandla ongaphezulu ukuya kuthi ga kwi-300 m²/g, i-alumina evuliweyo inokufunxa izixa ezibalulekileyo zomphunga wamanzi, iyenze ilungele usetyenziso apho ulawulo lokufuma lubalulekile.

Olunye lolona setyenziso luphambili lwe-alumina esebenzayo kukomisa iigesi kunye nolwelo. Kwiimeko zoshishino, kudla ngokusetyenziswa ukususa umswakama emoyeni ocinezelweyo kunye negesi yendalo, ukuthintela ukubola kunye nokuqinisekisa ukusebenza kakuhle kwezixhobo. Ukongeza, i-alumina esebenzayo isetyenziselwa ukuveliswa kweekhemikhali ezicocekileyo kunye namayeza, apho nokuba umkhondo wokufuma unokubeka esichengeni umgangatho wemveliso.

I-alumina esebenzayo ikwadlala indima ebalulekileyo kushishino lokucoca amanzi. Isebenza ngokufanelekileyo ekususeni i-fluoride kunye ne-arsenic emanzini okusela, okwenza kube yinto ebalulekileyo kwiinkqubo zokucoca amanzi. Ikhono layo lokubhengeza ukungcola ngelixa ligcina izinga eliphantsi le-leaching liqinisekisa ukuba amanzi acociweyo ahlala ekhuselekile ukusetyenziswa.

Ngaphezu koko, i-alumina evuliwe iphinda isetyenziswe. Inokuvuselelwa ngokufudumeza, ukuvumela ukuba ikhulule umswakama odibeneyo kwaye isetyenziswe ngokuphindaphindiweyo. Olu phawu alwenzi nje ukuba lube neendleko ezisebenzayo kodwa lukwakhusela nokusingqongileyo, njengoko lunciphisa inkunkuma ehambelana ne-desiccants enye yokusetyenziswa.

Ukuqukumbela, i-alumina esebenzayo yi-desiccant enamandla enezicelo ezahlukeneyo kumashishini ahlukeneyo. Izakhono zayo zokufunxa ukufuma, ezidityaniswe nokuphinda zisebenziseke kwakhona, ziyenza ibe sisixhobo esibalulekileyo sokugcina umgangatho wemveliso kunye nokhuseleko kwiindawo ezingevayo ukufuma.
