Embonini yamakhemikhali, ukuxuba uketshezi kumelela inqubo eyisisekelo yokusebenza, okubonakala ikakhulukazi ekukhiqizeni okunamathelayo. Phakathi nenqubo yokuxuba, ukwethulwa komoya kuvame ukuholela ekwakhekeni kwamabhamuza oketshezini, okungase kubeke engcupheni ikhwalithi yomkhiqizo. Ukuze kuqedwe lawa mabhamuza, i-vacuum degassing iye yavela njengesixazululo esisebenzayo sobuchwepheshe. Le nqubo isebenzisa amaphampu e-vacuum ukudala umehluko wengcindezi owandisa futhi ukhiphe amabhamuza abanjelwe oketshezini, ngaleyo ndlela kuthuthukiswe ubumsulwa bomkhiqizo nezici zokusebenza.
Inqubo ye-vacuum degassing isebenza ngezimiso ezimiswe kahle zomzimba. Njengoba iphampu yevacuum inciphisa ukucindezela ngaphezu kwendawo ewuketshezi, umehluko phakathi kwengcindezi yebhamuza yangaphakathi nendawo ezungezile kubangela amabhamuza ukuba ande futhi akhuphukele phezulu. Lokhu kwandiswa okulawulwayo kunika amandla ukususwa okuphumelelayo ngisho namabhamuza amancane abengahlala evaleleke kokubalulekile kwe-viscous. Emikhiqizweni yenani eliphezulu njengezinamathiseli ezibonakalayo noma ama-coatings anembayo, le nqubo ibalulekile ukuze kuqinisekiswe ukucaca okuphelele nokusebenza komsebenzi.
Kodwa-ke, inselele enkulu iphakama ngesikhathi sokukhishwa kwe-vacuum: amandla okudonsa amaconsi oketshezi noma igwebu empompini yevacuum. Lokhu akugcini nje ngokubeka engcupheni ukulimala komshini ezingxenyeni zangaphakathi zephampu kodwa futhi kulimaza ukusebenza kahle kokukhipha umoya. Ukuba khona kwe-liquid emafutheni wepompo kungaholela ekwakhekeni kwe-emulsion, ukunciphisa ukusebenza kahle kwe-lubrication futhi okungenzeka kubangele ukugqwala. Ezimweni ezimbi kakhulu, ukungena kwe-liquid kungase kubangele ukwehluleka kwephampu eyinhlekelele okudinga ukulungiswa okubanzi.
Ukubhekana nalolu daba olubucayi,izihlukanisi zegesi-uketshezizisebenza njengezinto ezibalulekile zokuvikela. Lezi zihlukanisi zisebenza ngezinqubo eziklanywe kahle - noma zisebenzisa amandla amaphakathi kumiklamo yohlobo lwesishingishane noma ukuhlukaniswa kwamandla adonsela phansi ekucushweni kohlobo lwe-baffle. Njengoba ingxube yoketshezi lomoya ingena kusihlukanisi, ukuminyana okuhlukene kwezingxenye kubangela ukuba zihlukane ngokwemvelo. Umfudlana wegesi ehlanzekile ube esedlulela empompini yevacuum kuyilapho uketshezi oluhlukanisiwe kukhishwa ngezindawo ezizinikele.
Ukuqaliswa kokuhlukaniswa okufanele kwe-gas-liquid kunikeza izinzuzo eziningi emisebenzini yokucubungula amakhemikhali. Inweba impilo yesevisi yepompo ye-vacuum ngo-40-60%, inciphisa imvamisa yokulungisa ngesigamu, futhi igcine amazinga ezinzile we-vacuum kuyo yonke inqubo yokukhipha umoya. Ngemisebenzi yokukhiqiza eqhubekayo, lokhu kwethembeka kuhumusha iziphazamiso ezimbalwa kanye nekhwalithi yomkhiqizo engaguquki.
Ngokusetshenziswa okuhlanganisiwe kobuchwepheshe bokukhipha i-vacuum degassing kanye nezinto ezifanele zokuvikela, imboni yamakhemikhali ifinyelela ukulawulwa kwekhwalithi yomkhiqizo ephakeme ngenkathi inciphisa ukukhubazeka okuhlobene nebhamuza. Iisihlukanisi segesi-uketshezingakho-ke akumeleli nje isisekeli kodwa ingxenye ebalulekile eqinisekisa kokubili ukusebenza kahle kwenqubo nokuvikelwa kwempahla ekusebenzeni okusekelwe ku-vacuum.
