Kwinkqubo yokucubungula umgubo, ukuxuba iipowder ezimbini kunokubonakala kulula, kodwa ukufezekisa umxube ofanayo nozinzileyo kufuna ukuqwalaselwa ngononophelo kweempawu zeesuntswana, amandla oomatshini, kunye neemeko zenkqubo.

Ngokungafaniyo nolwelo, iipowder azisasazeki ngokwemvelo kwinqanaba leemolekyuli. Ukuxubana kwazo kuxhomekeke kumandla angaphandle aveliswa zizixhobo zokuxuba. Kwangaxeshanye, ukuxubana nokwahlulahlula kwenzeka ngaxeshanye, nto leyo ethetha ukuba indlela yokuxuba engafanelekanga okanye uxinzelelo olukhulu loomatshini lunokubangela ukuba umxube uphinde wahlukane.

Ngoko ke, indlela yokuxuba iipowder ezimbini yingxaki yobunjineli ebandakanya iimpawu zepowder, iindlela zokuxuba, ukukhethwa kwezixhobo, kunye nolawulo lwenkqubo.

I. Isiseko Somzimba Sokuxuba I-Binary: Iindlela Ezintathu kunye Nokumelana Okubalulekileyo Okunye

1.1 Iindlela Ezintathu Ezisisiseko Zokuxuba

Ukuxuba umgubo kufezekiswa ngeendlela ezintathu eziphambili: ukujikeleza, ukucheba, kunye nokusasazwa.

Ukuxuba iConvectiveInoxanduva lokuhamba kwee-particle ezinkulu. Isasaza ngokukhawuleza ii-powders ezahlukeneyo kulo lonke igumbi lokuxuba kwaye ilawula inqanaba lokuqala lokuxuba.

Ukuxuba ukusikakwenzeka xa iileya zomgubo zihamba ngesantya esahlukileyo. Amandla okuxinana kunye nokunwebeka okubangelwayo kunceda ukwaphula ii-agglomerates kunye nokuphucula ukusasazeka kwamasuntswana.

Ukuxuba ukusasazekaibhekisa ekusasazweni ngokutsha kancinci kancinci kweesuntswana ngazinye ngokuhamba ngokungacwangciswanga kunye nokungqubana. Nangona icotha kune-convection kunye ne-shear, imisela ukulingana kokugqibela kokuxuba.

Umzekelo, kwi-mixer yohlobo lwe-V, i-convection ilawula inqanaba lokuqala lokuxuba, ngelixa ukusasazwa kwayo kuphucula ukufana kwenqanaba lamasuntswana ngokuthe ngcembe. Ukuqonda ezi ndlela kunceda ekumiseleni ixesha elifanelekileyo lokuxuba kunye nohlobo lwezixhobo.

1.2 Ukumelana Kokuqala Nokuxuba: Ulwakhiwo Lomgubo

Ngaphambi kokuba kuqalwe ukuxuba, iipowders zihlala zenza isakhiwo esizinzileyo ngenxa yokungqubana, ukudibana kwee-particles, kunye namandla adibeneyo. Esi sakhiwo sithintela intshukumo yee-particles kwaye sithintele ukuxubana okusebenzayo.

Kuyimfuneko indawo efanelekileyo ukuze kujikeleziswe umgubo. Yiyo loo nto uninzi lwabaxubi bomgubo besebenza ngomlinganiselo wokuzalisa omalunga nama-30%–60%. Ukuzalisa kakhulu kunciphisa ukuhamba kweentwana kwaye kunciphisa ukusebenza kakuhle kokuxuba.

II. Ukuvavanya iiMpawu zoMpuphu Ngaphambi kokuxuba

Inyathelo lokuqala ekukhetheni indlela yokuxuba kukuqonda iimpawu zomzimba zezi mpuphu zimbini.

Ukusasazwa kobungakanani beenxalenye

Umahluko omkhulu kubukhulu beesuntswana unyusa umngcipheko wokuhlukana. Iisuntswana ezincinci zinokuzalisa izikhewu phakathi kweesuntswana ezinkulu, ngelixa ukungcangcazela okanye ukuhamba kwezinto kunokubangela ukwahlukana emva kokuxubana.

Umahluko woxinano

Xa iipowder ezimbini zinobunzima obahlukeneyo kakhulu, iisuntswana ezinzima zidla ngokuhamba ziye ezantsi ngelixa iisuntswana ezikhaphukhaphu zisiya phezulu. Kwiimeko ezinjalo, kufuneka amandla okuxuba anamandla ukuze kugcinwe ukufana.

Ukuhamba kwamanzi

Iigubu ezingahambi kakuhle zidla ngokufuna ukuxuba ngokunyanzelekileyo. Iiparameter ezifana ne-angle yokuphumla kunye nokucinezeleka zinokunceda ekuvavanyeni indlela esebenza ngayo intshukumo yegubu.

Ukuthambekela kwe-Agglomeration

Iipowders ezicolekileyo, ingakumbi ezo ziqulethe umswakama, amafutha, okanye izinto ezidibeneyo, zinokwenza ii-agglomerates. Ezi zinto zihlala zifuna amandla aqinileyo okucheba ukuze kufezekiswe ukusasazeka okufanelekileyo.

III. Ukukhetha Izixhobo Zokuxuba Ezifanelekileyo

Umxubi ofanelekileyo uxhomekeke kakhulu kumahluko phakathi kwezi mpuphu zimbini kunye nomgangatho wokuxuba ofunekayo.

Uxinano Olufanayo kunye Nokuhamba Kakuhle

Kwimibhobho eneempawu ezifanayo zomzimba kunye nemfuneko yokugcina ukuthembeka kwamasuntswana, izixhobo zokuxuba ezithambileyo ezifanaAbaxubi bohlobo lwe-V okanye abaxubi beekhowuni ezimbinikufanelekile.

Ezi mixers zixhomekeke kakhulu ekusasazekeni nasekuhanjisweni komoya okuthambileyo, zibonelela ngokuxuba okufanayo ngelixa zinciphisa umonakalo wee-particles.

Umahluko omkhulu woxinano okanye ukungaphumi kakuhle kwamanzi

Xa iipowders zinomahluko omkhulu kubuninzi, ukuhamba kwamanzi, okanye ukuthambekela kokuhlangana, kufuneka amandla okuxuba anamandla.

Izixhobo ezifanaabaxubi beribhoni okanye abaxubi beplowinika i-convection enyanzelekileyo kunye nesenzo sokucheba, iphucula ukusebenza kakuhle kokusasazeka kunye nokunciphisa ixesha lokuxuba.

Umahluko Ogqithisileyo Kubungakanani Beenxalenye okanye Ubuninzi

Kwimigubo eneengxaki ezinkulu zokwahlukanisa, iindlela zokuxuba eziqhelekileyo zisenokunganeli. Iindlela ezongezelelweyo, ezifana neetekhnoloji zokuxuba ezikhethekileyo, iindlela zokutya eziphuculweyo, okanye uhlengahlengiso lwenkqubo, zinokufuneka ukugcina uzinzo lomxube.
