Zisebenza Kanjani Izixubi Zempuphu

I-powder mixer iyithuluzi elisetshenziswa ngomshini ukuxuba izinto ezahlukahlukene ezimpuphu ngokulinganayo. Isimiso sayo sokusebenza sisekelwe ezindleleni eziyisisekelo zokuxuba ezifana nokuxuba i-convection, ukuxuba i-shear, kanye nokuxuba i-diffusion, okwenza izinto zikwazi ukuhlangana ngokushesha nangokufana ngesikhathi esifushane.

Ukuxuba izinto ezimpuphu kusakazeke kakhulu ekukhiqizweni kwezimboni, okwenza kube yingxenye ebalulekile yenqubo yokukhiqiza. Isibonelo, ekukhiqizweni kokudla, umanyolo wezolimo, imithi, kanye namakhemikhali ansuku zonke, izinto ezinezakhiwo ezahlukene kumele zixutshwe ngokulinganayo ngesilinganiso esithile ngaphambi kokucutshungulwa ukuze kutholakale umkhiqizo wokugcina. Ngesikhathi sokukhiqiza, ukufana kokusatshalaliswa kwempuphu kuthinta ngqo umkhiqizo wokugcina.

Ukuxuba izinto kubhekisela enkambisweni yokunyakaza eyinkimbinkimbi lapho izinhlayiya ezimbili noma ngaphezulu zenza izinguquko endaweni kanye nesivinini ngaphansi kwethonya lamandla angaphandle (amandla omshini noma amandla adonsela phansi), okuholela ekubeni khona kwezinhlayiya eziningi ngokunyakaza okuhlobene kanye nokungena okuhlangene kumasethi azo ezinhlayiya. Le nqubo ivame ukuholela ekusatshalalisweni okufanayo kwezingxenye ezahlukene. Ngenxa yokuqhubeka kwe-macroscopic kanye nokwahlukana okuncane kwezinhlayiya, ukunyakaza kokuxuba kwezinhlayiya ezinezakhiwo ezahlukene kubonisa inqubo eyinkimbinkimbi kakhulu.

Ukuxuba i-powder eyomile kubhekisela enqubweni yokuxuba ngokulinganayo i-powder eyomile ezimbili noma ngaphezulu ukuqinisekisa ukusatshalaliswa okuqhubekayo kwengxenye ngayinye. Lobu buchwepheshe busetshenziswa kabanzi: embonini yokudla (ufulawa, izinongo, i-powder yeziphuzo, ama-premixes, njll.), embonini yezemithi (ukuxuba izithako ezisebenzayo kanye nezinto ezisizayo), embonini yamakhemikhali (umanyolo, insipho, izinto zokusetshenziswa zepulasitiki, njll.), kanye nasembonini yokudla (ukuxuba okusanhlamvu, amavithamini, namaminerali).

Ukuxuba i-powder ngokuvamile kuncike esenzweni sokusebenzisana kwezinqubo ezintathu: ukuhlanganisa, ukugunda, kanye nokusabalalisa.

Ukuxubana okuguqukayo kuhilela ukunyakaza okukhulu okungahleliwe kwezinhlayiya zempuphu. Ngaphansi kwethonya lamandla angaphandle, izinhlayiya zempuphu zithola ukuguquguquka okufana noketshezi, zisuka endaweni eyodwa ziye kwenye, zifinyelela ukusatshalaliswa okufanayo endaweni enkulu.

Ukuxuba ukugunda izinwele kuhilela ukugunda ngaphakathi kwezingxenye zempuphu. Ngaphansi kwethonya lamandla angaphandle, izinhlayiya zempuphu ziyashelelana, zakha izindawo eziningana ezishelelayo ngaphakathi kwezinto. Lezi zindawo ziyaxubana futhi zixubane njengezingqimba ezincane zoketshezi, ziqhubeke nokugunda impuphu ukuze kutholakale ukusatshalaliswa okufanayo ezindaweni ezisendaweni.

Ukuxubana kokusabalalisa kuyinqubo yokuxuba yendawo phakathi kwezinhlayiya ezimbili eziseduze ezingeni elincane kakhulu. Ngenxa yezinguquko ezikhundleni ezihambisanayo zezinhlayiya eziseduze, ukungena kanye nokuxubana kwenzeka, okuvumela izinto ukuthi zifinyelele ingxube efanayo ngokuphelele.

Inqubo yokuxuba ingahlukaniswa cishe ngezigaba ezintathu: ukuxuba okuguquguqukayo, isigaba esihilela kokubili ukuxhuma kanye nokusika, kanye nokuxuba ukusabalalisa.

Isigaba 1: Lesi sigaba sihilela ngokuyinhloko ukuxuba okuguquguqukayo, ngesivinini sokuxuba okusheshayo.

Isigaba 2: Lesi sigaba sihilela imiphumela ehlanganisiwe ye-convection kanye ne-shear, okuholela esikhathini eside sokuxuba.

Isigaba 3: Lesi yisigaba sokuxuba ukusabalalisa, lapho ingxube ilingana khona phakathi kokuxuba nokuhlukaniswa, kanti izinga lokulingana lishintshashintsha ngenani elithile.
