Ekucubungulweni kwempuphu, ukuxuba ama-powder amabili kungase kubonakale kulula, kodwa ukufeza ingxube efanayo nezinzile kudinga ukucatshangelwa ngokucophelela izakhiwo zezinhlayiya, amandla omshini, kanye nezimo zenqubo.

Ngokungafani noketshezi, impuphu ayisabalali ngokwemvelo ezingeni lama-molecule. Ukuxubana kwazo kuncike emandleni angaphandle akhiqizwa imishini yokuxuba. Ngesikhathi esifanayo, ukuxubana nokuhlukaniswa kwenzeka ngesikhathi esisodwa, okusho ukuthi indlela yokuxuba engafanele noma ukucindezeleka okukhulu kwemishini kungabangela ukuthi ingxube iphinde ihlukane.

Ngakho-ke, indlela yokuxuba izimpushana ezimbili empeleni iyinkinga yobunjiniyela ehilela izici zempushana, izindlela zokuxuba, ukukhethwa kwemishini, kanye nokulawulwa kwenqubo.

I. Isisekelo Esibonakalayo Sokuxuba Okubili: Izindlela Ezintathu Nokumelana Okukodwa Okuyisihluthulelo

1.1 Izindlela Ezintathu Eziyisisekelo Zokuxuba

Ukuxuba i-powder kufezwa ngezindlela ezintathu eziyinhloko: i-convection, i-shear, kanye ne-diffusion.

Ukuxubana kwe-Convectiveinesibopho sokunyakaza kwezinhlayiya ezinkulu. Isabalalisa ngokushesha izimpushana ezahlukene kulo lonke igumbi lokuxuba futhi ibusa isigaba sokuqala sokuxuba.

Ukuxubana kwe-Shearkwenzeka lapho izendlalelo zempuphu zihamba ngesivinini esihlukile. Ukungqubuzana okubangelwayo kanye namandla okwelula kusiza ukuphula ama-agglomerate futhi kuthuthukise ukuhlakazeka kwezinhlayiya.

Ukuxubana kokusabalalisakubhekisela ekusakazweni kabusha kancane kancane kwezinhlayiya ngazinye ngokunyakaza okungahleliwe kanye nokushayisana. Nakuba kuhamba kancane kune-convection kanye ne-shear, kunquma ukufana kokugcina kokuxubana.

Isibonelo, ku-mixer yohlobo lwe-V, i-convection ibusa isigaba sokuqala sokuxuba, kuyilapho ukusabalala kancane kancane kuthuthukisa ukufana kwezinga lezinhlayiya. Ukuqonda lezi zindlela kusiza ekunqumeni isikhathi esifanele sokuxuba kanye nohlobo lwemishini.

1.2 Ukumelana Kokuqala Nokuxuba: Isakhiwo Sempuphu

Ngaphambi kokuba kuqale ukuxuba, izimpushana zivame ukwakha isakhiwo esizinzile ngenxa yokungqubuzana, ukuhlangana kwezinhlayiya, kanye namandla okuhlangana. Lesi sakhiwo sivimbela ukunyakaza kwezinhlayiya futhi sivimbele ukuxubana okuphumelelayo.

Ngakho-ke kudingeka isikhala esikhululekile esifanele ukuze kujikelezwe i-powder. Yingakho iningi labaxubi be-powder lisebenza ngesilinganiso sokugcwalisa esingaba ngu-30%–60%. Ukugcwalisa ngokweqile kunciphisa ukunyakaza kwezinhlayiya futhi kunciphisa ukusebenza kahle kokuxuba.

II. Ukuhlola Izakhiwo Zempuphu Ngaphambi Kokuxuba

Isinyathelo sokuqala ekukhetheni indlela yokuxuba ukuqonda izakhiwo zomzimba zama-powder amabili.

Ukusatshalaliswa Kosayizi Wezinhlayiyana

Umehluko omkhulu ngobukhulu bezinhlayiya wandisa ingozi yokuhlukaniswa. Izinhlayiya ezincane zingagcwalisa izikhala phakathi kwezinhlayiya ezinkulu, kuyilapho ukudlidliza noma ukugeleza kwezinto kungabangela ukuhlukana ngemva kokuxubana.

Umehluko Wobuningi

Uma izimpushana ezimbili zinobukhulu obuhlukene kakhulu, izinhlayiya ezisindayo zivame ukwehla kanti izinhlayiya ezilula ziya phezulu. Ezimweni ezinjalo, kudingeka amandla okuxuba aqinile ukuze kugcinwe ukufana.

Ukugeleza kwamanzi

Izimpushana ezingahambi kahle ngokuvamile zidinga isenzo sokuphoqa ukuxuba. Amapharamitha anjenge-engeli yokuphumula kanye nokucindezelwa angasiza ekuhloleni ukuziphatha kokunyakaza kwempushana.

Ukuthambekela kwe-Agglomeration

Ama-powder amahle, ikakhulukazi lawo aqukethe umswakama, amafutha, noma izingxenye ezihlangene, angakha ama-agglomerate. Lezi zinto zivame ukudinga amandla aqinile okusika ukuze kutholakale ukuhlakazeka okufanele.

III. Ukukhetha Imishini Yokuxuba Efanele

Umxube ofanele uncike kakhulu emehluko phakathi kwalezi zimpushana ezimbili kanye nekhwalithi yokuxuba edingekayo.

Ubuningi obufanayo kanye nokugeleza okuhle

Ukuze uthole ama-powder anezakhiwo ezifanayo zomzimba kanye nesidingo sokugcina ubuqotho bezinhlayiya, imishini yokuxuba ethambile efanaAbaxubi bohlobo lwe-V noma abaxubi bekhoni eliphindwe kabilikufanelekile.

Laba baxubi bathembele kakhulu ekusabalaleni nasekuhlanganiseni okuthambile, okuhlinzeka ngokuxuba okufanayo ngenkathi kunciphisa umonakalo wezinhlayiya.

Umehluko Wobuningi Obukhulu Noma Ukugeleza Okubi

Uma izimpushana zinomehluko omkhulu ekujiyileni, ukugeleza, noma ukuthambekela kokuhlangana, kudingeka amandla okuxuba aqinile.

Imishini efanaabaxubi beribhoni noma abaxubi begejainikeza isenzo sokuphoqeleka sokudlulisa kanye nokusika, okuthuthukisa ukusebenza kahle kokuhlakazeka kanye nokunciphisa isikhathi sokuxuba.

Umehluko Omkhulu Ngosayizi Wezinhlayiyana Noma Ubuningi

Kuma-powder anezinkinga ezinkulu zokuhlukanisa, izindlela zokuxuba ezivamile zingase zinganeli. Amasu engeziwe, njengobuchwepheshe bokuxuba obukhethekile, izindlela zokudla ezilungiselelwe, noma ukulungiswa kwenqubo, kungadingeka ukuze kulondolozwe ukuqina kwengxube.
