Ukusetshenziswa kwezimboni ze-barium sulfate kungalandelwa emuva ekhulwini le-19, lapho abantu beqala ukubona amandla amakhulu ale powder emhlophe ekukhiqizeni izimboni. Ngenxa yokuminyana kwayo okuphezulu, ukuzinza okuhle kokushisa, ukungangeni kwamakhemikhali, kanye nezindawo ezingancibiliki emanzini, i-barium sulfate isetshenziswa kabanzi emikhakheni ehlukahlukene efana nokumboza, amapulasitiki, irabha, ukuthuthukiswa kwendawo kawoyela, kanye nokukhiqizwa kwe-ceramic.
Embonini yokumboza nopende, i-barium sulfate iyisigcwalisi esibalulekile ne-pigment engathuthukisa amandla okuvala, ukumelana nokugqoka, nokuqina kwezingubo. Ngenxa yobuningi obuphezulu kanye nezakhiwo ezinhle kakhulu ze-optical ze-barium sulfate, inganikeza umbala omhlophe omuhle, unikeze ukumboza ukubukeka okungcono nokusebenza kokuzivikela. Ngaphezu kwalokho, i-inertness yamakhemikhali ye-barium sulfate iphinde isho ukuthi ngeke isabele nezinye izingxenye ekugqokeni, ukuqinisekisa ukuzinza kwesikhathi eside kwengubo.
Embonini yepulasitiki nenjoloba, i-barium sulfate isetshenziswa njenge-filler ne-ejenti eqinisayo ukuze kuthuthukiswe izakhiwo zomzimba kanye nokumelana nesimo sezulu sezinto. Izakhiwo eziphakeme kakhulu ze-barium sulfate zenza imikhiqizo yepulasitiki neyerabha ibe nzima futhi ihlale isikhathi eside, kuyilapho ukuzinza kwayo okushisayo kusiza ukuthuthukisa ukumelana nokushisa kwezinto. Ngaphezu kwalokho, i-barium sulfate ingasetshenziswa futhi njenge-flame retardant ukuze kuthuthukiswe ukubambezeleka komlilo kwamapulasitiki nenjoloba.
Ekuthuthukisweni kwendawo kawoyela, i-barium sulfate yengezwa njenge-ejenti enesisindo kuketshezi lokumba ukuze kwandiswe ukuminyana kwalo. Lolu ketshezi olumbayo olunomthamo omkhulu lusiza ukulawula umfutho we-downhole futhi luvimbele izimo eziyingozi njengokushaywa umoya. Phakathi naleso sikhathi, ukuzinza kwamakhemikhali e-barium sulfate kusho nokuthi ngeke kusabele namanye amakhemikhali angaphansi komhlaba, okuqinisekisa ukuphepha kwenqubo yokumba.
I-Barium sulfate isetshenziswa kakhulu njenge-ejenti yombala kanye ne-glaze embonini ye-ceramic. Ngenxa yekhono layo lokuhlinzeka ngokuzinzile okumhlophe noma eminye imibala ethile, i-barium sulfate isetshenziswa kabanzi ekukhiqizeni imikhiqizo ye-ceramic. Ngaphezu kwalokho, i-barium sulfate nayo ingathuthukisa ukumelana nokushisa namandla omshini wemikhiqizo ye-ceramic.
Ukukhiqizwa kwe-barium sulfate kuvame ukwenziwa ngezindlela ezimbili eziyinhloko: ukucubungula amaminerali emvelo kanye nokuhlanganiswa kwamakhemikhali. Ukucutshungulwa kwamaminerali emvelo ngokuyinhloko kukhipha i-barium sulfate ku-barite ore, kuyilapho ukuhlanganiswa kwamakhemikhali kulungisa i-barium sulfate ngokusabela kosawoti we-barium nama-sulfate. Kungakhathaliseki ukuthi iyiphi indlela esetshenzisiwe, ukulawulwa kwekhwalithi okuqinile kanye nezinqubo zokuhlanza kuyadingeka ukuze kuqinisekiswe ukuhlanzeka nokusebenza komkhiqizo wokugcina.
Nakuba i-barium sulfate inezinzuzo eziningi ekusetshenzisweni kwezimboni, ukukhiqizwa nokusetshenziswa kwayo kungase kube nomthelela othile emvelweni. Isibonelo, ngesikhathi sokukhishwa kanye nokucutshungulwa kwe-barium sulfate, uthuli namanzi angcolile angase akhiqizwe, futhi izinyathelo ezifanele zokwelashwa nokubuyisela kuyadingeka ukuze kuncishiswe ukungcoliswa kwemvelo. Ngaphezu kwalokho, ngesikhathi sokusetshenziswa kwe-barium sulfate, ukunakwa kufanele futhi kukhokhwe ukuze kugwenywe ukungena kwayo emanzini nasenhlabathini, ukuze kugwenywe ukulimala okungenzeka ku-ecosystem.
I-Barium sulfate isetshenziswa kabanzi emkhakheni wezimboni, idlala indima ebalulekile ekuthuthukiseni ukusebenza komkhiqizo nokusebenza kahle kokukhiqiza njengokugcwalisa, i-ejenti eqinisayo, i-ejenti yombala, ne-ejenti enesisindo. Ngokuthuthukiswa kobuchwepheshe bezimboni kanye nesidingo esikhulayo sokuvikelwa kwemvelo, ukukhiqizwa nokusetshenziswa kwe-barium sulfate kuzophinde kuthuthukiswe ngokuqhubekayo ukuze kuzuzwe izicelo zezimboni ezisimeme futhi ezinobungani bemvelo. Esikhathini esizayo, ukusetshenziswa kwe-barium sulfate emkhakheni wezimboni kuzoqhubeka kwanda, okwenza umnikelo omkhulu ekuthuthukiseni izimboni ezihlukahlukene.
