Emkhiqizweni wezimboni, ukugqokwa kwemishini bekulokhu kuyisici esibalulekile esithinta ukusebenza kahle kokukhiqiza nempilo yemishini. Ngokuthuthuka okuqhubekayo kobuchwepheshe bezinto ezibonakalayo, ukugqokwa{1}}kwezinto zobumba eziqinile, njengohlobo olusha lwempahla engagqoki{2}}, sekuthole ukunakwa kancane kancane. Ngakho-ke, yini ngempela-izinto zobumba eziqinile ezigqokayo? Kalula nje, yi-ceramic material ngokuyinhloko eyenziwe nge-alumina, efakwe emazingeni okushisa aphezulu, futhi inobulukhuni obuphakeme kakhulu nokumelana nokugqoka.
Ukusetshenziswa okubanzi kwezitsha zobumba-ezingagugi emikhakheni yezimboni ikakhulukazi kubangelwe ukusebenza kwazo okuhle kakhulu. Okokuqala, abonisa ubulukhuni obuphakeme kakhulu, afinyelela esikalini se-Mohs ebangeni lesi-9, okwesibili ngemuva kwedayimane, okuvumela ukumelana ngokuphumelelayo nokungqubuzana nomthelela wezinto ezihlukahlukene. Ezimbonini ezifana nemishini yezimayini, okokusebenza kukasimende, namandla okukhiqiza amandla ashisayo, lapho ukuthuthwa kwezinto ezibonakalayo kanye nezinqubo zokuchotshozwa kuvame ukuba izinto zokusebenza ziguge, ukusetshenziswa{4}}kobumba obuqinile obungagugi ukuze bavikeleke kunganweba kakhulu isikhathi sokuphila kwemishini. Okwesibili,{6}}izitsha zobumba ezigugayo zinokuzinza okuhle kwamakhemikhali, ukumelana ne-asidi nokugqwala kwe-alkali, okuzivumela ukuthi zisebenze ngokujwayelekile ngisho nasezindaweni ezigqwala kakhulu.
Ngokungeziwe ekusebenziseni kwayo ekuvikelweni kwemishini yezimboni,{0}}izinto zobumba ezigugayo nazo zinikeza izinzuzo ezihlukile kwezinye izinkambu. Ngokwesibonelo, embonini ye-petrochemical, ingasetshenziswa ukuvikela izindonga zangaphakathi zamapayipi, ukunciphisa ukuguga nokugqwala okubangelwa imithombo yezindaba. Kubunjiniyela bama-hydraulic, bungasetshenziswa ekugqokeni-ukwelashwa okungazweli kwezingxenye ezifana namasango nezinjini zomoya, okuthuthukisa ukusebenza{4}}kokugqokwa kwezinto zokusebenza. Ngaphezu kwalokho,-izitsha zobumba ezingagugi zidlala indima enkulu emikhakheni efana nemishini yobumba nemishini yokucubungula ukudla, ehlinzeka ngosekelo olubalulekile lwemishini kulezi zimboni.
